[tzaharia] - -* Update documentation for :dependent declaration so that it explicitly uses the non-deprecated API. [Jack Danger Canty] - -* Add documentation caveat about when to use count_by_sql. [fearoffish] - -* Enhance documentation for increment_counter and decrement_counter. [fearoffish] - -* Provide brief introduction to what optimistic locking is. [fearoffish] - -* Add documentation for :encoding option to mysql adapter. [marclove] - -* Added short-hand declaration style to migrations (inspiration from Sexy Migrations, http://errtheblog.com/post/2381) [David Heinemeier Hansson]. Example: - - create_table "products" do |t| - t.column "shop_id", :integer - t.column "creator_id", :integer - t.column "name", :string, :default => "Untitled" - t.column "value", :string, :default => "Untitled" - t.column "created_at", :datetime - t.column "updated_at", :datetime - end - - ...can now be written as: - - create_table :products do |t| - t.integer :shop_id, :creator_id - t.string :name, :value, :default => "Untitled" - t.timestamps - end - -* Use association name for the wrapper element when using .to_xml. Previous behavior lead to non-deterministic situations with STI and polymorphic associations. [Michael Koziarski, jstrachan] - -* Improve performance of calling .create on has_many :through associations. [evan] - -* Improved cloning performance by relying less on exception raising #8159 [Blaine] - -* Added ActiveRecord::Base.inspect to return a column-view like # [David Heinemeier Hansson] - -* Added yielding of Builder instance for ActiveRecord::Base#to_xml calls [David Heinemeier Hansson] - -* Small additions and fixes for ActiveRecord documentation.

[court3nay] - -* SQLite: binary escaping works with $KCODE='u'. #7862 [tsuka] - -* Base#to_xml supports serialized attributes. #7502 [jonathan] - -* Base.update_all :order and :limit options. Useful for MySQL updates that must be ordered to avoid violating unique constraints. [Jeremy Kemper] - -* Remove deprecated object transactions. People relying on this functionality should install the object_transactions plugin at http://code.bitsweat.net/svn/object_transactions. Closes #5637 [Michael Koziarski, Jeremy Kemper] - -* PostgreSQL: remove DateTime -> Time downcast. Warning: do not enable translate_results for the C bindings if you have timestamps outside Time's domain. [Jeremy Kemper] - -* find_or_create_by_* takes a hash so you can create with more attributes than are in the method name. For example, Person.find_or_create_by_name(:name => 'Henry', :comments => 'Hi new user!') is equivalent to Person.find_by_name('Henry') || Person.create(:name => 'Henry', :comments => 'Hi new user!'). #7368 [Josh Susser] - -* Make sure with_scope takes both :select and :joins into account when setting :readonly. Allows you to save records you retrieve using method_missing on a has_many :through associations. [Michael Koziarski] - -* Allow a polymorphic :source for has_many :through associations.

Example: - - transaction do |transaction| - david.withdrawal(100) - mary.deposit(100) - transaction.rollback! # rolls back the transaction that was otherwise going to be successful - end - -* Made increment_counter/decrement_counter play nicely with optimistic locking, and added a more general update_counters method [Jamis Buck] - -* Reworked David's query cache to be available as Model.cache {...}. For the duration of the block no select query should be run more then once. Any inserts/deletes/executes will flush the whole cache however [Tobias Lütke] - Task.cache { Task.find(1); Task.find(1) } # => 1 query - -* When dealing with SQLite3, use the table_info pragma helper, so that the bindings can do some translation for when sqlite3 breaks incompatibly between point releases. [Jamis Buck] - -* Oracle: fix lob and text default handling. #7344 [gfriedrich, Michael Schoen] - -* SQLServer: don't choke on strings containing 'null'. #7083 [Jakob Skjerning] - -* MySQL: blob and text columns may not have defaults in 5.x. Update fixtures schema for strict mode. #6695 [Dan Kubb] - -* update_all can take a Hash argument. sanitize_sql splits into two methods for conditions and assignment since NULL values and delimiters are handled differently. #6583, #7365 [sandofsky, Assaf] - -* MySQL: SET SQL_AUTO_IS_NULL=0 so 'where id is null' doesn't select the last inserted id. #6778 [Jonathan Viney, timc] - -* Use Date#to_s(:db) for quoted dates. #7411 [Michael Schoen] - -* Don't create instance writer methods for class attributes. Closes #7401 [Rick Olson] - -* Docs: validations examples. #7343 [zackchandler] - -* Add missing tests ensuring callbacks work with class inheritance. Closes #7339 [sandofsky] - -* Fixtures use the table name and connection from set_fixture_class. #7330 [Anthony Eden] - -* Remove useless code in #attribute_present? since 0 != blank?.

Skip column options for primary keys. #6956, #7048 [Dan Manges, Jeremy Kemper] - -* MySQL, PostgreSQL: change_column_default quotes the default value and doesn't lose column type information. #3987, #6664 [Jonathan Viney, Manfred Stienstra, altano@bigfoot.com] - -* Oracle: create_table takes a :sequence_name option to override the 'tablename_seq' default. #7000 [Michael Schoen] - -* MySQL: retain SSL settings on reconnect. #6976 [randyv2] - -* Apply scoping during initialize instead of create. Fixes setting of foreign key when using find_or_initialize_by with scoping.

[Obie Fernandez, Jeremy Kemper] - -* Oracle: fix connection reset failure. #6846 [leonlleslie] - -* Subclass instantiation doesn't try to explicitly require the corresponding subclass. #6840 [leei, Jeremy Kemper] - -* fix faulty inheritance tests and that eager loading grabs the wrong inheritance column when the class of your association is an STI subclass. Closes #6859 [protocool] - -* Consolidated different create and create! versions to call through to the base class with scope. This fixes inconsistencies, especially related to protected attribtues. Closes #5847 [Alexander Dymo, Tobias Lütke] - -* find supports :lock with :include. Check whether your database allows SELECT ... FOR UPDATE with outer joins before using. #6764 [vitaly, Jeremy Kemper] - -* Add AssociationCollection#create! to be consistent with AssociationCollection#create when dealing with a foreign key that is a protected attribute [Cody Fauser] - -* Added counter optimization for AssociationCollection#any? so person.friends.any? won't actually load the full association if we have the count in a cheaper form [David Heinemeier Hansson] - -* Change fixture_path to a class inheritable accessor allowing test cases to have their own custom set of fixtures. #6672 [Zach Dennis] - -* Quote ActiveSupport::Multibyte::Chars. #6653 [Julian Tarkhanov] - -* Simplify query_attribute by typecasting the attribute value and checking whether it's nil, false, zero or blank. #6659 [Jonathan Viney] - -* validates_numericality_of uses \A \Z to ensure the entire string matches rather than ^ $ which may match one valid line of a multiline string. #5716 [Andreas Schwarz] - -* Run validations in the order they were declared. #6657 [obrie] - -* MySQL: detect when a NOT NULL column without a default value is misreported as default ''. Can't detect for string, text, and binary columns since '' is a legitimate default. #6156 [simon@redhillconsulting.com.au, obrie, Jonathan Viney, Jeremy Kemper] - -* Simplify association proxy implementation by factoring construct_scope out of method_missing. #6643 [martin] - -* Oracle: automatically detect the primary key. #6594 [vesaria, Michael Schoen] - -* Oracle: to increase performance, prefetch 100 rows and enable similar cursor sharing. Both are configurable in database.yml. #6607 [philbogle@gmail.com, ray.fortna@jobster.com, Michael Schoen] - -* Don't inspect unloaded associations. #2905 [lmarlow] - -* SQLite: use AUTOINCREMENT primary key in >= 3.1.0. #6588, #6616 [careo, lukfugl] - -* Cache inheritance_column. #6592 [Stefan Kaes] - -* Firebird: decimal/numeric support. #6408 [macrnic] - -* make add_order a tad faster. #6567 [Stefan Kaes] - -* Find with :include respects scoped :order. #5850 - -* Support nil and Array in :conditions => { attr => value } hashes. #6548 [Assaf, Jeremy Kemper] - find(:all, :conditions => { :topic_id => [1, 2, 3], :last_read => nil } - -* Consistently use LOWER() for uniqueness validations (rather than mixing with UPPER()) so the database can always use a functional index on the lowercased column. #6495 [Si] - -* SQLite: fix calculations workaround, remove count(distinct) query rewrite, cleanup test connection scripts. [Jeremy Kemper] - -* SQLite: count(distinct) queries supported in >= 3.2.6. #6544 [Bob Silva] - -* Dynamically generate reader methods for serialized attributes. #6362 [Stefan Kaes] - -* Deprecation: object transactions warning.

Don't start a transaction in create_fixtures if a transaction is started. #6282 [Jacob Fugal, Jeremy Kemper] - -* Add #delete support to has_many :through associations. Closes #6049 [Martin Landers] - -* Reverted old select_limited_ids_list postgresql fix that caused issues in mysql. Closes #5851 [Rick Olson] - -* Removes the ability for eager loaded conditions to be interpolated, since there is no model instance to use as a context for interpolation. #5553 [turnip@turnipspatch.com] - -* Added timeout option to SQLite3 configurations to deal more gracefully with SQLite3::BusyException, now the connection can instead retry for x seconds to see if the db clears up before throwing that exception #6126 [wreese@gmail.com] - -* Added update_attributes! which uses save! to raise an exception if a validation error prevents saving #6192 [jonathan] - -* Deprecated add_on_boundary_breaking (use validates_length_of instead) #6292 [Bob Silva] - -* The has_many create method works with polymorphic associations. #6361 [Dan Peterson] - -* MySQL: introduce Mysql::Result#all_hashes to support further optimization. #5581 [Stefan Kaes] - -* save! shouldn't validate twice. #6324 [maiha, Bob Silva] - -* Association collections have an _ids reader method to match the existing writer for collection_select convenience (e.g. employee.task_ids). The writer method skips blank ids so you can safely do @employee.task_ids = params[:tasks] without checking every time for an empty list or blank values. #1887, #5780 [Michael Schuerig] - -* Add an attribute reader method for ActiveRecord::Base.observers [Rick Olson] - -* Deprecation: count class method should be called with an options hash rather than two args for conditions and joins. #6287 [Bob Silva] - -* has_one associations with a nil target may be safely marshaled. #6279 [norbauer, Jeremy Kemper] - -* Duplicate the hash provided to AR::Base#to_xml to prevent unexpected side effects [Michael Koziarski] - -* Add a :namespace option to AR::Base#to_xml [Michael Koziarski] - -* Deprecation tests. Remove warnings for dynamic finders and for the foo_count method if it's also an attribute. [Jeremy Kemper] - -* Mock Time.now for more accurate Touch mixin tests. #6213 [Dan Peterson] - -* Improve yaml fixtures error reporting. #6205 [Bruce Williams] - -* Rename AR::Base#quote so people can use that name in their models. #3628 [Michael Koziarski] - -* Add deprecation warning for inferred foreign key. #6029 [Josh Susser] - -* Fixed the Ruby/MySQL adapter we ship with Active Record to work with the new authentication handshake that was introduced in MySQL 4.1, along with the other protocol changes made at that time #5723 [jimw@mysql.com] - -* Deprecation: use :dependent => :delete_all rather than :exclusively_dependent => true. #6024 [Josh Susser] - -* Document validates_presences_of behavior with booleans: you probably want validates_inclusion_of :attr, :in => [true, false]. #2253 [Bob Silva] - -* Optimistic locking: gracefully handle nil versions, treat as zero. #5908 [Tom Ward] - -* to_xml: the :methods option works on arrays of records. #5845 [Josh Starcher] - -* Deprecation: update docs. #5998 [Jakob Skjerning, Kevin Clark] - -* Add some XmlSerialization tests for ActiveRecord [Rick Olson] - -* has_many :through conditions are sanitized by the associating class. #5971 [martin.emde@gmail.com] - -* Tighten rescue clauses. #5985 [james@grayproductions.net] - -* Fix spurious newlines and spaces in AR::Base#to_xml output [Jamis Buck] - -* has_one supports the :dependent => :delete option which skips the typical callback chain and deletes the associated object directly from the database. #5927 [Chris Mear, Jonathan Viney] - -* Nested subclasses are not prefixed with the parent class' table_name since they should always use the base class' table_name. #5911 [Jonathan Viney] - -* SQLServer: work around bug where some unambiguous date formats are not correctly identified if the session language is set to german. #5894 [Tom Ward, kruth@bfpi] - -* SQLServer: fix eager association test. #5901 [Tom Ward] - -* Clashing type columns due to a sloppy join shouldn't wreck single-table inheritance. #5838 [Kevin Clark] - -* Fixtures: correct escaping of \n and \r. #5859 [evgeny.zislis@gmail.com] - -* Migrations: gracefully handle missing migration files. #5857 [eli.gordon@gmail.com] - -* MySQL: update test schema for MySQL 5 strict mode. #5861 [Tom Ward] - -* to_xml: correct naming of included associations. #5831 [Josh Starcher] - -* Pushing a record onto a has_many :through sets the association's foreign key to the associate's primary key and adds it to the correct association. #5815, #5829 [Josh Susser] - -* Add records to has_many :through using <<, push, and concat by creating the association record. Raise if base or associate are new records since both ids are required to create the association. #build raises since you can't associate an unsaved record. #create! takes an attributes hash and creates the associated record and its association in a transaction. [Jeremy Kemper] - - # Create a tagging to associate the post and tag. - post.tags << Tag.find_by_name('old') - post.tags.create! :name => 'general' - - # Would have been: - post.taggings.create!(:tag => Tag.find_by_name('finally') - transaction do - post.taggings.create!(:tag => Tag.create!(:name => 'general')) - end - -* Cache nil results for :included has_one associations also. #5787 [Michael Schoen] - -* Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. [Tobias Lütke] - -* Nested classes are given table names prefixed by the singular form of the parent's table name. [Jeremy Kemper] - Example: Invoice::Lineitem is given table name invoice_lineitems - -* Migrations: uniquely name multicolumn indexes so you don't have to. [Jeremy Kemper] - # people_active_last_name_index, people_active_deactivated_at_index - add_index :people, [:active, :last_name] - add_index :people, [:active, :deactivated_at] - remove_index :people, [:active, :last_name] - remove_index :people, [:active, :deactivated_at] - - WARNING: backward-incompatibility. Multicolumn indexes created before this - revision were named using the first column name only. Now they're uniquely - named using all indexed columns. - - To remove an old multicolumn index, remove_index :table_name, :first_column - -* Fix for deep includes on the same association. [richcollins@gmail.com] - -* Tweak fixtures so they don't try to use a non-ActiveRecord class. [Kevin Clark] - -* Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. [Rick Olson] - -* Document find's :from option. Closes #5762. [andrew@redlinesoftware.com] - -* PostgreSQL: autodetected sequences work correctly with multiple schemas. Rely on the schema search_path instead of explicitly qualifying the sequence name with its schema. #5280 [guy.naor@famundo.com] - -* Replace Reloadable with Reloadable::Deprecated. [Nicholas Seckar] - -* Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757. [Michael Schoen] - -* Add documentation for how to disable timestamps on a per model basis. Closes #5684. [matt@mattmargolis.net Marcel Molina Jr.] - -* Don't save has_one associations unnecessarily. #5735 [Jonathan Viney] - -* Refactor ActiveRecord::Base.reset_subclasses to #reset, and add global observer resetting. [Rick Olson] - -* Formally deprecate the deprecated finders. [Michael Koziarski] - -* Formally deprecate rich associations. [Michael Koziarski] - -* Fixed that default timezones for new / initialize should uphold utc setting #5709 [daniluk@yahoo.com] - -* Fix announcement of very long migration names. #5722 [blake@near-time.com] - -* The exists? class method should treat a string argument as an id rather than as conditions. #5698 [jeremy@planetargon.com] - -* Fixed to_xml with :include misbehaviors when invoked on array of model instances #5690 [alexkwolfe@gmail.com] - -* Added support for conditions on Base.exists? #5689 [Josh Peek]. Examples: - - assert (Topic.exists?(:author_name => "David")) - assert (Topic.exists?(:author_name => "Mary", :approved => true)) - assert (Topic.exists?(["parent_id = ?", 1])) - -* Schema dumper quotes date :default values. [Dave Thomas] - -* Calculate sum with SQL, not Enumerable on HasManyThrough Associations. [Dan Peterson] - -* Factor the attribute#{suffix} methods out of method_missing for easier extension. [Jeremy Kemper] - -* Patch sql injection vulnerability when using integer or float columns. [Jamis Buck] - -* Allow #count through a has_many association to accept :include.

[Zed Shaw] - -* PostgreSQL: return array fields as strings. #4664 [Robby Russell] - -* SQLServer: added tests to ensure all database statements are closed, refactored identity_insert management code to use blocks, removed update/delete rowcount code out of execute and into update/delete, changed insert to go through execute method, removed unused quoting methods, disabled pessimistic locking tests as feature is currently unsupported, fixed RakeFile to load sqlserver specific tests whether running in ado or odbc mode, fixed support for recently added decimal types, added support for limits on integer types. #5670 [Tom Ward] - -* SQLServer: fix db:schema:dump case-sensitivity. #4684 [Will Rogers] - -* Oracle: BigDecimal support. #5667 [Michael Schoen] - -* Numeric and decimal columns map to BigDecimal instead of Float. Those with scale 0 map to Integer. #5454 [robbat2@gentoo.org, work@ashleymoran.me.uk] - -* Firebird migrations support. #5337 [Ken Kunz ] - -* PostgreSQL: create/drop as postgres user. #4790 [mail@matthewpainter.co.uk, mlaster@metavillage.com] - -* Update callbacks documentation. #3970 [Robby Russell ] - -* PostgreSQL: correctly quote the ' in pk_and_sequence_for. #5462 [tietew@tietew.net] - -* PostgreSQL: correctly quote microseconds in timestamps. #5641 [rick@rickbradley.com] - -* Clearer has_one/belongs_to model names (account has_one :user). #5632 [matt@mattmargolis.net] - -* Oracle: use nonblocking queries if allow_concurrency is set, fix pessimistic locking, don't guess date vs. time by default (set OracleAdapter.emulate_dates = true for the old behavior), adapter cleanup. #5635 [Michael Schoen] - -* Fixed a few Oracle issues: Allows Oracle's odd date handling to still work consistently within #to_xml, Passes test that hardcode insert statement by dropping the :id column, Updated RUNNING_UNIT_TESTS with Oracle instructions, Corrects method signature for #exec #5294 [Michael Schoen] - -* Added :group to available options for finds done on associations #5516 [mike@michaeldewey.org] - -* Minor tweak to improve performance of ActiveRecord::Base#to_param. - -* Observers also watch subclasses created after they are declared. #5535 [daniels@pronto.com.au] - -* Removed deprecated timestamps_gmt class methods. [Jeremy Kemper] - -* rake build_mysql_database grants permissions to rails@localhost. #5501 [brianegge@yahoo.com] - -* PostgreSQL: support microsecond time resolution. #5492 [alex@msgpad.com] - -* Add AssociationCollection#sum since the method_missing invokation has been shadowed by Enumerable#sum. - -* Added find_or_initialize_by_X which works like find_or_create_by_X but doesn't save the newly instantiated record. [Sam Stephenson] - -* Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE". Use the #lock! method to obtain a row lock on a single record (reloads the record with :lock => true). [Shugo Maeda] - # Obtain an exclusive lock on person 1 so we can safely increment visits. - Person.transaction do - # select * from people where id=1 for update - person = Person.find(1, :lock => true) - person.visits += 1 - person.save! - end - -* PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency. [Jeremy Kemper] - -* Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. [Jeremy Kemper] - -* Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. [Nicholas Seckar] - -* Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de) - -* Refactored ActiveRecord::Base.to_xml to become a delegate for XmlSerializer, which restores sanity to the mega method. This refactoring also reinstates the opinions that type="string" is redundant and ugly and nil-differentiation is not a concern of serialization [David Heinemeier Hansson] - -* Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example: - - Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2) - -...is the same as: - - Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2) - - This makes it easier to pass in the options from a form or otherwise outside. - - -* Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 [kennethkunz@gmail.com] - -* Fixed usage of :limit and with_scope when the association in scope is a 1:m #5208 [alex@purefiction.net] - -* Fixed migration trouble with SQLite when NOT NULL is used in the new definition #5215 [greg@lapcominc.com] - -* Fixed problems with eager loading and counting on SQL Server #5212 [kajism@yahoo.com] - -* Fixed that count distinct should use the selected column even when using :include #5251 [anna@wota.jp] - -* Fixed that :includes merged from with_scope won't cause the same association to be loaded more than once if repetition occurs in the clauses #5253 [alex@purefiction.net] - -* Allow models to override to_xml. #4989 [Blair Zajac ] - -* PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 [shimbo@is.naist.jp] - -* Records and arrays of records are bound as quoted ids. [Jeremy Kemper] - Foo.find(:all, :conditions => ['bar_id IN (?)', bars]) - Foo.find(:first, :conditions => ['bar_id = ?', bar]) - -* Fixed that Base.find :all, :conditions => [ "id IN (?)", collection ] would fail if collection was empty [David Heinemeier Hansson] - -* Add a list of regexes assert_queries skips in the ActiveRecord test suite. [Rick Olson] - -* Fix the has_and_belongs_to_many #create doesn't populate the join for new records.

Raise if base or associate are new records since both ids are required to create the association. #build raises since you can't associate an unsaved record. #create! takes an attributes hash and creates the associated record and its association in a transaction. [Jeremy Kemper] - - # Create a tagging to associate the post and tag. - post.tags << Tag.find_by_name('old') - post.tags.create! :name => 'general' - - # Would have been: - post.taggings.create!(:tag => Tag.find_by_name('finally') - transaction do - post.taggings.create!(:tag => Tag.create!(:name => 'general')) - end - -* Cache nil results for :included has_one associations also. #5787 [Michael Schoen] - -* Fixed a bug which would cause .save to fail after trying to access a empty has_one association on a unsaved record. [Tobias Lütke] - -* Nested classes are given table names prefixed by the singular form of the parent's table name. [Jeremy Kemper] - Example: Invoice::Lineitem is given table name invoice_lineitems - -* Migrations: uniquely name multicolumn indexes so you don't have to.

Multicolumn indexes created before this - revision were named using the first column name only. Now they're uniquely - named using all indexed columns. - - To remove an old multicolumn index, remove_index :table_name, :first_column - -* Fix for deep includes on the same association. [richcollins@gmail.com] - -* Tweak fixtures so they don't try to use a non-ActiveRecord class. [Kevin Clark] - -* Remove ActiveRecord::Base.reset since Dispatcher doesn't use it anymore. [Rick Olson] - -* PostgreSQL: autodetected sequences work correctly with multiple schemas. Rely on the schema search_path instead of explicitly qualifying the sequence name with its schema. #5280 [guy.naor@famundo.com] - -* Replace Reloadable with Reloadable::Deprecated. [Nicholas Seckar] - -* Cache nil results for has_one associations so multiple calls don't call the database. Closes #5757.

[Sam Stephenson] - -* Row locking. Provide a locking clause with the :lock finder option or true for the default "FOR UPDATE". Use the #lock! method to obtain a row lock on a single record (reloads the record with :lock => true). [Shugo Maeda] - # Obtain an exclusive lock on person 1 so we can safely increment visits. - Person.transaction do - # select * from people where id=1 for update - person = Person.find(1, :lock => true) - person.visits += 1 - person.save! - end - -* PostgreSQL: introduce allow_concurrency option which determines whether to use blocking or asynchronous #execute. Adapters with blocking #execute will deadlock Ruby threads. The default value is ActiveRecord::Base.allow_concurrency. [Jeremy Kemper] - -* Use a per-thread (rather than global) transaction mutex so you may execute concurrent transactions on separate connections. [Jeremy Kemper] - -* Change AR::Base#to_param to return a String instead of a Fixnum. Closes #5320. [Nicholas Seckar] - -* Use explicit delegation instead of method aliasing for AR::Base.to_param -> AR::Base.id. #5299 (skaes@web.de) - -* Refactored ActiveRecord::Base.to_xml to become a delegate for XmlSerializer, which restores sanity to the mega method. This refactoring also reinstates the opinions that type="string" is redundant and ugly and nil-differentiation is not a concern of serialization [David Heinemeier Hansson] - -* Added simple hash conditions to find that'll just convert hash to an AND-based condition string #5143 [Hampton Catlin]. Example: - - Person.find(:all, :conditions => { :last_name => "Catlin", :status => 1 }, :limit => 2) - -...is the same as: - - Person.find(:all, :conditions => [ "last_name = ? and status = ?", "Catlin", 1 ], :limit => 2) - - This makes it easier to pass in the options from a form or otherwise outside. - - -* Fixed issues with BLOB limits, charsets, and booleans for Firebird #5194, #5191, #5189 [kennethkunz@gmail.com] - -* Fixed usage of :limit and with_scope when the association in scope is a 1:m #5208 [alex@purefiction.net] - -* Fixed migration trouble with SQLite when NOT NULL is used in the new definition #5215 [greg@lapcominc.com] - -* Fixed problems with eager loading and counting on SQL Server #5212 [kajism@yahoo.com] - -* Fixed that count distinct should use the selected column even when using :include #5251 [anna@wota.jp] - -* Fixed that :includes merged from with_scope won't cause the same association to be loaded more than once if repetition occurs in the clauses #5253 [alex@purefiction.net] - -* Allow models to override to_xml. #4989 [Blair Zajac ] - -* PostgreSQL: don't ignore port when host is nil since it's often used to label the domain socket. #5247 [shimbo@is.naist.jp] - -* Records and arrays of records are bound as quoted ids.

[Jeremy Evans] #4144 - -* Alias the has_and_belongs_to_many join table on eager includes. #4106 [Jeremy Evans] - - This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous. - - Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL') - -* Oracle adapter gets some love #4230 [Michael Schoen] - - * Changes :text to CLOB rather than BLOB [Moses Hohman] - * Fixes an issue with nil numeric length/scales (several) - * Implements support for XMLTYPE columns [wilig / Kubo Takehiro] - * Tweaks a unit test to get it all green again - * Adds support for #current_database - -* Added Base.abstract_class? that marks which classes are not part of the Active Record hierarchy #3704 [Rick Olson] - - class CachedModel < ActiveRecord::Base - self.abstract_class = true - end - - class Post < CachedModel - end - - CachedModel.abstract_class? - => true - - Post.abstract_class? - => false - - Post.base_class - => Post - - Post.table_name - => 'posts' - -* Allow :dependent options to be used with polymorphic joins. #3820 [Rick Olson] - - class Foo < ActiveRecord::Base - has_many :attachments, :as => :attachable, :dependent => :delete_all - end - -* Nicer error message on has_many :through when :through reflection can not be found. #4042 [court3nay] - -* Upgrade to Transaction::Simple 1.3 [Jamis Buck] - -* Catch FixtureClassNotFound when using instantiated fixtures on a fixture that has no ActiveRecord model [Rick Olson] - -* Allow ordering of calculated results and/or grouped fields in calculations [solo@gatelys.com] - -* Make ActiveRecord::Base#save! return true instead of nil on success. #4173 [johan@johansorensen.com] - -* Dynamically set allow_concurrency. #4044 [Stefan Kaes] - -* Added Base#to_xml that'll turn the current record into a XML representation [David Heinemeier Hansson]. Example: - - topic.to_xml - - ...returns: - - - - The First Topic - David - 1 - false - 0 - 2000-01-01 08:28:00 - 2003-07-16 09:28:00 - Have a nice day - david@loudthinking.com - - 2004-04-15 - - - ...and you can configure with: - - topic.to_xml(:skip_instruct => true, :except => [ :id, bonus_time, :written_on, replies_count ]) - - ...that'll return: - - - The First Topic - David - false - Have a nice day - david@loudthinking.com - - 2004-04-15 - - - You can even do load first-level associations as part of the document: - - firm.to_xml :include => [ :account, :clients ] - - ...that'll return something like: - - - - 1 - 1 - 37signals - - - 1 - Summit - - - 1 - Microsoft - - - - 1 - 50 - - - -* Allow :counter_cache to take a column name for custom counter cache columns [Jamis Buck] - -* Documentation fixes for :dependent [robby@planetargon.com] - -* Stop the MySQL adapter crashing when views are present. #3782 [Jonathan Viney] - -* Don't classify the belongs_to class, it is already singular #4117 [keithm@infused.org] - -* Allow set_fixture_class to take Classes instead of strings for a class in a module. Raise FixtureClassNotFound if a fixture can't load. [Rick Olson] - -* Fix quoting of inheritance column for STI eager loading #4098 [Jonathan Viney ] - -* Added smarter table aliasing for eager associations for multiple self joins #3580 [Rick Olson] - - * The first time a table is referenced in a join, no alias is used. - * After that, the parent class name and the reflection name are used. - - Tree.find(:all, :include => :children) # LEFT OUTER JOIN trees AS tree_children ... - - * Any additional join references get a numerical suffix like '_2', '_3', etc. - -* Fixed eager loading problems with single-table inheritance #3580 [Rick Olson]. Post.find(:all, :include => :special_comments) now returns all posts, and any special comments that the posts may have. And made STI work with has_many :through and polymorphic belongs_to. - -* Added cascading eager loading that allows for queries like Author.find(:all, :include=> { :posts=> :comments }), which will fetch all authors, their posts, and the comments belonging to those posts in a single query (using LEFT OUTER JOIN) #3913 [anna@wota.jp]. Examples: - - # cascaded in two levels - >> Author.find(:all, :include=>{:posts=>:comments}) - => authors - +- posts - +- comments - - # cascaded in two levels and normal association - >> Author.find(:all, :include=>[{:posts=>:comments}, :categorizations]) - => authors - +- posts - +- comments - +- categorizations - - # cascaded in two levels with two has_many associations - >> Author.find(:all, :include=>{:posts=>[:comments, :categorizations]}) - => authors - +- posts - +- comments - +- categorizations - - # cascaded in three levels - >> Company.find(:all, :include=>{:groups=>{:members=>{:favorites}}}) - => companies - +- groups - +- members - +- favorites - -* Make counter cache work when replacing an association #3245 [eugenol@gmail.com] - -* Make migrations verbose [Jamis Buck] - -* Make counter_cache work with polymorphic belongs_to [Jamis Buck] - -* Fixed that calling HasOneProxy#build_model repeatedly would cause saving to happen #4058 [anna@wota.jp] - -* Added Sybase database adapter that relies on the Sybase Open Client bindings (see http://raa.ruby-lang.org/project/sybase-ctlib) #3765 [John Sheets]. It's almost completely Active Record compliant (including migrations), but has the following caveats: - - * Does not support DATE SQL column types; use DATETIME instead. - * Date columns on HABTM join tables are returned as String, not Time. - * Insertions are potentially broken for :polymorphic join tables - * BLOB column access not yet fully supported - -* Clear stale, cached connections left behind by defunct threads. [Jeremy Kemper] - -* CHANGED DEFAULT: set ActiveRecord::Base.allow_concurrency to false. Most AR usage is in single-threaded applications. [Jeremy Kemper] - -* Renamed the "oci" adapter to "oracle", but kept the old name as an alias #4017 [Michael Schoen] - -* Fixed that Base.save should always return false if the save didn't succeed, including if it has halted by before_save's #1861, #2477 [David Heinemeier Hansson] - -* Speed up class -> connection caching and stale connection verification. #3979 [Stefan Kaes] - -* Add set_fixture_class to allow the use of table name accessors with models which use set_table_name.

Introducing the disconnect! instance method for the PostgreSQL, MySQL, and SQL Server adapters; implementations for the others are welcome. #3591 [Simon Stapleton, Tom Ward] - -* Added support for nested scopes #3407 [anna@wota.jp]. Examples: - - Developer.with_scope(:find => { :conditions => "salary > 10000", :limit => 10 }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (salary > 10000) LIMIT 10 - - # inner rule is used. (all previous parameters are ignored) - Developer.with_exclusive_scope(:find => { :conditions => "name = 'Jamis'" }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (name = 'Jamis') - end - - # parameters are merged - Developer.with_scope(:find => { :conditions => "name = 'Jamis'" }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (( salary > 10000 ) AND ( name = 'Jamis' )) LIMIT 10 - end - end - -* Fixed db2 connection with empty user_name and auth options #3622 [phurley@gmail.com] - -* Fixed validates_length_of to work on UTF-8 strings by using characters instead of bytes #3699 [Masao Mutoh] - -* Fixed that reflections would bleed across class boundaries in single-table inheritance setups #3796 [Lars Pind] - -* Added calculations: Base.count, Base.average, Base.sum, Base.minimum, Base.maxmium, and the generic Base.calculate. All can be used with :group and :having. Calculations and statitics need no longer require custom SQL. #3958 [Rick Olson]. Examples: - - Person.average :age - Person.minimum :age - Person.maximum :age - Person.sum :salary, :group => :last_name - -* Renamed Errors#count to Errors#size but kept an alias for the old name (and included an alias for length too) #3920 [Luke Redpath] - -* Reflections don't attempt to resolve module nesting of association classes. Simplify type computation. [Jeremy Kemper] - -* Improved the Oracle OCI Adapter with better performance for column reflection (from #3210), fixes to migrations (from #3476 and #3742), tweaks to unit tests (from #3610), and improved documentation (from #2446) #3879 [Aggregated by schoenm@earthlink.net] - -* Fixed that the schema_info table used by ActiveRecord::Schema.define should respect table pre- and suffixes #3834 [rubyonrails@atyp.de] - -* Added :select option to Base.count that'll allow you to select something else than * to be counted on. Especially important for count queries using DISTINCT #3839 [Stefan Kaes] - -* Correct syntax error in mysql DDL, and make AAACreateTablesTest run first [Bob Silva] - -* Allow :include to be used with has_many :through associations #3611 [Michael Schoen] - -* PostgreSQL: smarter schema dumps using pk_and_sequence_for(table). #2920 [Blair Zajac] - -* SQLServer: more compatible limit/offset emulation. #3779 [Tom Ward] - -* Polymorphic join support for has_one associations (has_one :foo, :as => :bar) #3785 [Rick Olson] - -* PostgreSQL: correctly parse negative integer column defaults. #3776 [bellis@deepthought.org] - -* Fix problems with count when used with :include [Jeremy Hopple and Kevin Clark] - -* ActiveRecord::RecordInvalid now states which validations failed in its default error message [Tobias Lütke] - -* Using AssociationCollection#build with arrays of hashes should call build, not create [David Heinemeier Hansson] - -* Remove definition of reloadable? from ActiveRecord::Base to make way for new Reloadable code.

For example Base.reflection_of_all_associations(:has_many) [David Heinemeier Hansson] - -* Added ActiveRecord::SchemaDumper.ignore_tables which tells SchemaDumper which tables to ignore. Useful for tables with funky column like the ones required for tsearch2. [Tobias Lütke] - -* SchemaDumper now doesn't fail anymore when there are unknown column types in the schema. Instead the table is ignored and a Comment is left in the schema.rb. [Tobias Lütke] - -* Fixed that saving a model with multiple habtm associations would only save the first one. #3244 [yanowitz-rubyonrails@quantumfoam.org, Florian Weber] - -* Fix change_column to work with PostgreSQL 7.x and 8.x. #3141 [wejn@box.cz, Rick Olson, Scott Barron] - -* removed :piggyback in favor of just allowing :select on :through associations.

This allows you to act on the habtm association as you please while preserving referential integrity. #2065 [larrywilliams1@gmail.com, sam.kirchmeier@gmail.com, elliot@townx.org, Jeremy Kemper] - -* Deprecate the old, confusing :exclusively_dependent option in favor of :dependent => :delete_all. [Jeremy Kemper] - -* More compatible Oracle column reflection. #2771 [Ryan Davis , Michael Schoen ] - - -*1.13.0* (November 7th, 2005) - -* Fixed faulty regex in get_table_name method (SQLServerAdapter) #2639 [Ryan Tomayko] - -* Added :include as an option for association declarations [David Heinemeier Hansson]. Example: - - has_many :posts, :include => [ :author, :comments ] - -* Rename Base.constrain to Base.with_scope so it doesn't conflict with existing concept of database constraints. Make scoping more robust: uniform method => parameters, validated method names and supported finder parameters, raise exception on nested scopes. [Jeremy Kemper] Example: - - Comment.with_scope(:find => { :conditions => 'active=true' }, :create => { :post_id => 5 }) do - # Find where name = ? and active=true - Comment.find :all, :conditions => ['name = ?', name] - # Create comment associated with :post_id - Comment.create :body => "Hello world" - end - -* Fixed that SQL Server should ignore :size declarations on anything but integer and string in the agnostic schema representation #2756 [Ryan Tomayko] - -* Added constrain scoping for creates using a hash of attributes bound to the :creation key [David Heinemeier Hansson]. Example: - - Comment.constrain(:creation => { :post_id => 5 }) do - # Associated with :post_id - Comment.create :body => "Hello world" - end - - This is rarely used directly, but allows for find_or_create on associations. So you can do: - - # If the tag doesn't exist, a new one is created that's associated with the person - person.tags.find_or_create_by_name("Summer") - -* Added find_or_create_by_X as a second type of dynamic finder that'll create the record if it doesn't already exist [David Heinemeier Hansson]. Example: - - # No 'Summer' tag exists - Tag.find_or_create_by_name("Summer") # equal to Tag.create(:name => "Summer") - - # Now the 'Summer' tag does exist - Tag.find_or_create_by_name("Summer") # equal to Tag.find_by_name("Summer") - -* Added extension capabilities to has_many and has_and_belongs_to_many proxies [David Heinemeier Hansson]. Example: - - class Account < ActiveRecord::Base - has_many :people do - def find_or_create_by_name(name) - first_name, *last_name = name.split - last_name = last_name.join " " - - find_or_create_by_first_name_and_last_name(first_name, last_name) - end - end - end - - person = Account.find(:first).people.find_or_create_by_name("David Heinemeier Hansson") - person.first_name # => "David" - person.last_name # => "Heinemeier Hansson" - - Note that the anoymous module must be declared using brackets, not do/end (due to order of evaluation). - -* Omit internal dtproperties table from SQLServer table list. #2729 [Ryan Tomayko] - -* Quote column names in generated SQL. #2728 [Ryan Tomayko] - -* Correct the pure-Ruby MySQL 4.1.1 shim's version test. #2718 [Jeremy Kemper] - -* Add Model.create! to match existing model.save! method. When save! raises RecordInvalid, you can catch the exception, retrieve the invalid record (invalid_exception.record), and see its errors (invalid_exception.record.errors). [Jeremy Kemper] - -* Correct fixture behavior when table name pluralization is off. #2719 [Rick Bradley ] - -* Changed :dbfile to :database for SQLite adapter for consistency (old key still works as an alias) #2644 [Dan Peterson] - -* Added migration support for Oracle #2647 [Michael Schoen] - -* Worked around that connection can't be reset if allow_concurrency is off. #2648 [Michael Schoen ] - -* Fixed SQL Server adapter to pass even more tests and do even better #2634 [Ryan Tomayko] - -* Fixed SQL Server adapter so it honors options[:conditions] when applying :limits #1978 [Tom Ward] - -* Added migration support to SQL Server adapter (please someone do the same for Oracle and DB2) #2625 [Tom Ward] - -* Use AR::Base.silence rather than AR::Base.logger.silence in fixtures to preserve Log4r compatibility. #2618 [dansketcher@gmail.com] - -* Constraints are cloned so they can't be inadvertently modified while they're -in effect. Added :readonly finder constraint. Calling an association collection's class method (Part.foobar via item.parts.foobar) constrains :readonly => false since the collection's :joins constraint would otherwise force it to true. [Jeremy Kemper ] - -* Added :offset and :limit to the kinds of options that Base.constrain can use #2466 [duane.johnson@gmail.com] - -* Fixed handling of nil number columns on Oracle and cleaned up tests for Oracle in general #2555 [Michael Schoen] - -* Added quoted_true and quoted_false methods and tables to db2_adapter and cleaned up tests for DB2 #2493, #2624 [maik schmidt] - - -*1.12.2* (October 26th, 2005) - -* Allow symbols to rename columns when using SQLite adapter. #2531 [Kevin Clark] - -* Map Active Record time to SQL TIME. #2575, #2576 [Robby Russell ] - -* Clarify semantics of ActiveRecord::Base#respond_to? #2560 [Stefan Kaes] - -* Fixed Association#clear for associations which have not yet been accessed. #2524 [Patrick Lenz ] - -* HABTM finders shouldn't return readonly records. #2525 [Patrick Lenz ] - -* Make all tests runnable on their own. #2521. [Blair Zajac ] - - -*1.12.1* (October 19th, 2005) - -* Always parenthesize :conditions options so they may be safely combined with STI and constraints. - -* Correct PostgreSQL primary key sequence detection. #2507 [tmornini@infomania.com] - -* Added support for using limits in eager loads that involve has_many and has_and_belongs_to_many associations - - -*1.12.0* (October 16th, 2005) - -* Update/clean up documentation (rdoc) - -* PostgreSQL sequence support. Use set_sequence_name in your model class to specify its primary key sequence. #2292 [Rick Olson , Robby Russell ] - -* Change default logging colors to work on both white and black backgrounds. [Sam Stephenson] - -* YAML fixtures support ordered hashes for fixtures with foreign key dependencies in the same table. #1896 [purestorm@ggnore.net] - -* :dependent now accepts :nullify option. Sets the foreign key of the related objects to NULL instead of deleting them. #2015 [Robby Russell ] - -* Introduce read-only records. If you call object.readonly! then it will mark the object as read-only and raise ReadOnlyRecord if you call object.save. object.readonly? reports whether the object is read-only. Passing :readonly => true to any finder method will mark returned records as read-only. The :joins option now implies :readonly, so if you use this option, saving the same record will now fail. Use find_by_sql to work around. - -* Avoid memleak in dev mode when using fcgi - -* Simplified .clear on active record associations by using the existing delete_records method. #1906 [Caleb ] - -* Delegate access to a customized primary key to the conventional id method. #2444. [Blair Zajac ] - -* Fix errors caused by assigning a has-one or belongs-to property to itself - -* Add ActiveRecord::Base.schema_format setting which specifies how databases should be dumped [Sam Stephenson] - -* Update DB2 adapter. #2206. [contact@maik-schmidt.de] - -* Corrections to SQLServer native data types. #2267. [rails.20.clarry@spamgourmet.com] - -* Deprecated ActiveRecord::Base.threaded_connection in favor of ActiveRecord::Base.allow_concurrency. - -* Protect id attribute from mass assigment even when the primary key is set to something else. #2438. [Blair Zajac ] - -* Misc doc fixes (typos/grammar/etc.). #2430. [coffee2code] - -* Add test coverage for content_columns. #2432. [coffee2code] - -* Speed up for unthreaded environments. #2431. [Stefan Kaes] - -* Optimization for Mysql selects using mysql-ruby extension greater than 2.6.3. #2426. [Stefan Kaes] - -* Speed up the setting of table_name. #2428. [Stefan Kaes] - -* Optimize instantiation of STI subclass records. In partial fullfilment of #1236. [Stefan Kaes] - -* Fix typo of 'constrains' to 'contraints'. #2069. [Michael Schuerig ] - -* Optimization refactoring for add_limit_offset!. In partial fullfilment of #1236. [Stefan Kaes] - -* Add ability to get all siblings, including the current child, with acts_as_tree. Recloses #2140. [Michael Schuerig ] - -* Add geometric type for postgresql adapter. #2233 [Andrew Kaspick] - -* Add option (true by default) to generate reader methods for each attribute of a record to avoid the overhead of calling method missing. In partial fullfilment of #1236. [Stefan Kaes] - -* Add convenience predicate methods on Column class. In partial fullfilment of #1236. [Stefan Kaes] - -* Raise errors when invalid hash keys are passed to ActiveRecord::Base.find. #2363 [Chad Fowler , Nicholas Seckar] - -* Added :force option to create_table that'll try to drop the table if it already exists before creating - -* Fix transactions so that calling return while inside a transaction will not leave an open transaction on the connection. [Nicholas Seckar] - -* Use foreign_key inflection uniformly. #2156 [Blair Zajac ] - -* model.association.clear should destroy associated objects if :dependent => true instead of nullifying their foreign keys. #2221 [joergd@pobox.com, ObieFernandez ] - -* Returning false from before_destroy should cancel the action. #1829 [Jeremy Huffman] - -* Recognize PostgreSQL NOW() default as equivalent to CURRENT_TIMESTAMP or CURRENT_DATE, depending on the column's type. #2256 [mat ] - -* Extensive documentation for the abstract database adapter. #2250 [François Beausoleil ] - -* Clean up Fixtures.reset_sequences for PostgreSQL. Handle tables with no rows and models with custom primary keys. #2174, #2183 [jay@jay.fm, Blair Zajac ] - -* Improve error message when nil is assigned to an attr which validates_size_of within a range. #2022 [Manuel Holtgrewe ] - -* Make update_attribute use the same writer method that update_attributes uses. - #2237 [trevor@protocool.com] - -* Make migrations honor table name prefixes and suffixes. #2298 [Jakob Skjerning, Marcel Molina Jr.] - -* Correct and optimize PostgreSQL bytea escaping. #1745, #1837 [dave@cherryville.org, ken@miriamtech.com, bellis@deepthought.org] - -* Fixtures should only reset a PostgreSQL sequence if it corresponds to an integer primary key named id. #1749 [chris@chrisbrinker.com] - -* Standardize the interpretation of boolean columns in the Mysql and Sqlite adapters. (Use MysqlAdapter.emulate_booleans = false to disable this behavior) - -* Added new symbol-driven approach to activating observers with Base#observers= [David Heinemeier Hansson]. Example: - - ActiveRecord::Base.observers = :cacher, :garbage_collector - -* Added AbstractAdapter#select_value and AbstractAdapter#select_values as convenience methods for selecting single values, instead of hashes, of the first column in a SELECT #2283 [solo@gatelys.com] - -* Wrap :conditions in parentheses to prevent problems with OR's #1871 [Jamis Buck] - -* Allow the postgresql adapter to work with the SchemaDumper. [Jamis Buck] - -* Add ActiveRecord::SchemaDumper for dumping a DB schema to a pure-ruby file, making it easier to consolidate large migration lists and port database schemas between databases. [Jamis Buck] - -* Fixed migrations for Windows when using more than 10 [David Naseby] - -* Fixed that the create_x method from belongs_to wouldn't save the association properly #2042 [Florian Weber] - -* Fixed saving a record with two unsaved belongs_to associations pointing to the same object #2023 [Tobias Lütke] - -* Improved migrations' behavior when the schema_info table is empty. [Nicholas Seckar] - -* Fixed that Observers didn't observe sub-classes #627 [Florian Weber] - -* Fix eager loading error messages, allow :include to specify tables using strings or symbols. Closes #2222 [Marcel Molina Jr.] - -* Added check for RAILS_CONNECTION_ADAPTERS on startup and only load the connection adapters specified within if its present (available in Rails through config.connection_adapters using the new config) #1958 [skae] - -* Fixed various problems with has_and_belongs_to_many when using customer finder_sql #2094 [Florian Weber] - -* Added better exception error when unknown column types are used with migrations #1814 [François Beausoleil] - -* Fixed "connection lost" issue with the bundled Ruby/MySQL driver (would kill the app after 8 hours of inactivity) #2163, #428 [kajism@yahoo.com] - -* Fixed comparison of Active Record objects so two new objects are not equal #2099 [deberg] - -* Fixed that the SQL Server adapter would sometimes return DBI::Timestamp objects instead of Time #2127 [Tom Ward] - -* Added the instance methods #root and #ancestors on acts_as_tree and fixed siblings to not include the current node #2142, #2140 [coffee2code] - -* Fixed that Active Record would call SHOW FIELDS twice (or more) for the same model when the cached results were available #1947 [sd@notso.net] - -* Added log_level and use_silence parameter to ActiveRecord::Base.benchmark. The first controls at what level the benchmark statement will be logged (now as debug, instead of info) and the second that can be passed false to include all logging statements during the benchmark block/ - -* Make sure the schema_info table is created before querying the current version #1903 - -* Fixtures ignore table name prefix and suffix #1987 [Jakob Skjerning] - -* Add documentation for index_type argument to add_index method for migrations #2005 [Blaine] - -* Modify read_attribute to allow a symbol argument #2024 [Ken Kunz] - -* Make destroy return self #1913 [Sebastian Kanthak] - -* Fix typo in validations documentation #1938 [court3nay] - -* Make acts_as_list work for insert_at(1) #1966 [hensleyl@papermountain.org] - -* Fix typo in count_by_sql documentation #1969 [Alexey Verkhovsky] - -* Allow add_column and create_table to specify NOT NULL #1712 [emptysands@gmail.com] - -* Fix create_table so that id column is implicitly added [Rick Olson] - -* Default sequence names for Oracle changed to #{table_name}_seq, which is the most commonly used standard. In addition, a new method ActiveRecord::Base#set_sequence_name allows the developer to set the sequence name per model. This is a non-backwards-compatible change -- anyone using the old-style "rails_sequence" will need to either create new sequences, or set: ActiveRecord::Base.set_sequence_name = "rails_sequence" #1798 - -* OCIAdapter now properly handles synonyms, which are commonly used to separate out the schema owner from the application user #1798 - -* Fixed the handling of camelCase columns names in Oracle #1798 - -* Implemented for OCI the Rakefile tasks of :clone_structure_to_test, :db_structure_dump, and :purge_test_database, which enable Oracle folks to enjoy all the agile goodness of Rails for testing. Note that the current implementation is fairly limited -- only tables and sequences are cloned, not constraints or indexes. A full clone in Oracle generally requires some manual effort, and is version-specific. Post 9i, Oracle recommends the use of the DBMS_METADATA package, though that approach requires editing of the physical characteristics generated #1798 - -* Fixed the handling of multiple blob columns in Oracle if one or more of them are null #1798 - -* Added support for calling constrained class methods on has_many and has_and_belongs_to_many collections #1764 [Tobias Lütke] - - class Comment < AR:B - def self.search(q) - find(:all, :conditions => ["body = ?", q]) - end - end - - class Post < AR:B - has_many :comments - end - - Post.find(1).comments.search('hi') # => SELECT * from comments WHERE post_id = 1 AND body = 'hi' - - NOTICE: This patch changes the underlying SQL generated by has_and_belongs_to_many queries. If your relying on that, such as - by explicitly referencing the old t and j aliases, you'll need to update your code. Of course, you _shouldn't_ be relying on - details like that no less than you should be diving in to touch private variables. But just in case you do, consider yourself - noticed :) - -* Added migration support for SQLite (using temporary tables to simulate ALTER TABLE) #1771 [Sam Stephenson] - -* Remove extra definition of supports_migrations? from abstract_adaptor.rb [Nicholas Seckar] - -* Fix acts_as_list so that moving next-to-last item to the bottom does not result in duplicate item positions - -* Fixed incompatibility in DB2 adapter with the new limit/offset approach #1718 [Maik Schmidt] - -* Added :select option to find which can specify a different value than the default *, like find(:all, :select => "first_name, last_name"), if you either only want to select part of the columns or exclude columns otherwise included from a join #1338 [Stefan Kaes] - - -*1.11.1* (11 July, 2005) - -* Added support for limit and offset with eager loading of has_one and belongs_to associations. Using the options with has_many and has_and_belongs_to_many associations will now raise an ActiveRecord::ConfigurationError #1692 [Rick Olson] - -* Fixed that assume_bottom_position (in acts_as_list) could be called on items already last in the list and they would move one position away from the list #1648 [tyler@kianta.com] - -* Added ActiveRecord::Base.threaded_connections flag to turn off 1-connection per thread (required for thread safety). By default it's on, but WEBrick in Rails need it off #1685 [Sam Stephenson] - -* Correct reflected table name for singular associations. #1688 [court3nay] - -* Fixed optimistic locking with SQL Server #1660 [tom@popdog.net] - -* Added ActiveRecord::Migrator.migrate that can figure out whether to go up or down based on the target version and the current - -* Added better error message for "packets out of order" #1630 [court3nay] - -* Fixed first run of "rake migrate" on PostgreSQL by not expecting a return value on the id #1640 - - -*1.11.0* (6 July, 2005) - -* Fixed that Yaml error message in fixtures hid the real error #1623 [Nicholas Seckar] - -* Changed logging of SQL statements to use the DEBUG level instead of INFO - -* Added new Migrations framework for describing schema transformations in a way that can be easily applied across multiple databases #1604 [Tobias Lütke] See documentation under ActiveRecord::Migration and the additional support in the Rails rakefile/generator. - -* Added callback hooks to association collections #1549 [Florian Weber]. Example: - - class Project - has_and_belongs_to_many :developers, :before_add => :evaluate_velocity - - def evaluate_velocity(developer) - ... - end - end - - ..raising an exception will cause the object not to be added (or removed, with before_remove). - - -* Fixed Base.content_columns call for SQL Server adapter #1450 [DeLynn Berry] - -* Fixed Base#write_attribute to work with both symbols and strings #1190 [Paul Legato] - -* Fixed that has_and_belongs_to_many didn't respect single table inheritance types #1081 [Florian Weber] - -* Speed up ActiveRecord#method_missing for the common case (read_attribute). - -* Only notify observers on after_find and after_initialize if these methods are defined on the model. #1235 [Stefan Kaes] - -* Fixed that single-table inheritance sub-classes couldn't be used to limit the result set with eager loading #1215 [Chris McGrath] - -* Fixed validates_numericality_of to work with overrided getter-method when :allow_nil is on #1316 [raidel@onemail.at] - -* Added roots, root, and siblings to the batch of methods added by acts_as_tree #1541 [Michael Schuerig] - -* Added support for limit/offset with the MS SQL Server driver so that pagination will now work #1569 [DeLynn Berry] - -* Added support for ODBC connections to MS SQL Server so you can connect from a non-Windows machine #1569 [Mark Imbriaco/DeLynn Berry] - -* Fixed that multiparameter posts ignored attr_protected #1532 [alec+rails@veryclever.net] - -* Fixed problem with eager loading when using a has_and_belongs_to_many association using :association_foreign_key #1504 [flash@vanklinkenbergsoftware.nl] - -* Fixed Base#find to honor the documentation on how :joins work and make them consistent with Base#count #1405 [pritchie@gmail.com]. What used to be: - - Developer.find :all, :joins => 'developers_projects', :conditions => 'id=developer_id AND project_id=1' - - ...should instead be: - - Developer.find( - :all, - :joins => 'LEFT JOIN developers_projects ON developers.id = developers_projects.developer_id', - :conditions => 'project_id=1' - ) - -* Fixed that validations didn't respecting custom setting for too_short, too_long messages #1437 [Marcel Molina Jr.] - -* Fixed that clear_association_cache doesn't delete new associations on new records (so you can safely place new records in the session with Action Pack without having new associations wiped) #1494 [cluon] - -* Fixed that calling Model.find([]) returns [] and doesn't throw an exception #1379 - -* Fixed that adding a record to a has_and_belongs_to collection would always save it -- now it only saves if its a new record #1203 [Alisdair McDiarmid] - -* Fixed saving of in-memory association structures to happen as a after_create/after_update callback instead of after_save -- that way you can add new associations in after_create/after_update callbacks without getting them saved twice - -* Allow any Enumerable, not just Array, to work as bind variables #1344 [Jeremy Kemper] - -* Added actual database-changing behavior to collection assigment for has_many and has_and_belongs_to_many #1425 [Sebastian Kanthak]. - Example: - - david.projects = [Project.find(1), Project.new("name" => "ActionWebSearch")] - david.save - - If david.projects already contain the project with ID 1, this is left unchanged. Any other projects are dropped. And the new - project is saved when david.save is called. - - Also included is a way to do assignments through IDs, which is perfect for checkbox updating, so you get to do: - - david.project_ids = [1, 5, 7] - -* Corrected typo in find SQL for has_and_belongs_to_many. #1312 [ben@bensinclair.com] - -* Fixed sanitized conditions for has_many finder method. #1281 [jackc@hylesanderson.com, pragdave, Tobias Lütke] - -* Comprehensive PostgreSQL schema support. Use the optional schema_search_path directive in database.yml to give a comma-separated list of schemas to search for your tables. This allows you, for example, to have tables in a shared schema without having to use a custom table name. See http://www.postgresql.org/docs/8.0/interactive/ddl-schemas.html to learn more. #827 [dave@cherryville.org] - -* Corrected @@configurations typo #1410 [david@ruppconsulting.com] - -* Return PostgreSQL columns in the order they were declared #1374 [perlguy@gmail.com] - -* Allow before/after update hooks to work on models using optimistic locking - -* Eager loading of dependent has_one associations won't delete the association #1212 - -* Added a second parameter to the build and create method for has_one that controls whether the existing association should be replaced (which means nullifying its foreign key as well). By default this is true, but false can be passed to prevent it. - -* Using transactional fixtures now causes the data to be loaded only once. - -* Added fixture accessor methods that can be used when instantiated fixtures are disabled. - - fixtures :web_sites - - def test_something - assert_equal "Ruby on Rails", web_sites(:rubyonrails).name - end - -* Added DoubleRenderError exception that'll be raised if render* is called twice #518 [Nicholas Seckar] - -* Fixed exceptions occuring after render has been called #1096 [Nicholas Seckar] - -* CHANGED: validates_presence_of now uses Errors#add_on_blank, which will make " " fail the validation where it didn't before #1309 - -* Added Errors#add_on_blank which works like Errors#add_on_empty, but uses Object#blank? instead - -* Added the :if option to all validations that can either use a block or a method pointer to determine whether the validation should be run or not. #1324 [Duane Johnson/jhosteny]. Examples: - - Conditional validations such as the following are made possible: - validates_numericality_of :income, :if => :employed? - - Conditional validations can also solve the salted login generator problem: - validates_confirmation_of :password, :if => :new_password? - - Using blocks: - validates_presence_of :username, :if => Proc.new { |user| user.signup_step > 1 } - -* Fixed use of construct_finder_sql when using :join #1288 [dwlt@dwlt.net] - -* Fixed that :delete_sql in has_and_belongs_to_many associations couldn't access record properties #1299 [Rick Olson] - -* Fixed that clone would break when an aggregate had the same name as one of its attributes #1307 [Jeremy Kemper] - -* Changed that destroying an object will only freeze the attributes hash, which keeps the object from having attributes changed (as that wouldn't make sense), but allows for the querying of associations after it has been destroyed. - -* Changed the callbacks such that observers are notified before the in-object callbacks are triggered. Without this change, it wasn't possible to act on the whole object in something like a before_destroy observer without having the objects own callbacks (like deleting associations) called first. - -* Added option for passing an array to the find_all version of the dynamic finders and have it evaluated as an IN fragment. Example: - - # SELECT * FROM topics WHERE title IN ('First', 'Second') - Topic.find_all_by_title(["First", "Second"]) - -* Added compatibility with camelCase column names for dynamic finders #533 [Dee Zsombor] - -* Fixed extraneous comma in count() function that made it not work with joins #1156 [Jarkko Laine/Dee Zsombor] - -* Fixed incompatibility with Base#find with an array of ids that would fail when using eager loading #1186 [Alisdair McDiarmid] - -* Fixed that validate_length_of lost :on option when :within was specified #1195 [jhosteny@mac.com] - -* Added encoding and min_messages options for PostgreSQL #1205 [Shugo Maeda]. Configuration example: - - development: - adapter: postgresql - database: rails_development - host: localhost - username: postgres - password: - encoding: UTF8 - min_messages: ERROR - -* Fixed acts_as_list where deleting an item that was removed from the list would ruin the positioning of other list items #1197 [Jamis Buck] - -* Added validates_exclusion_of as a negative of validates_inclusion_of - -* Optimized counting of has_many associations by setting the association to empty if the count is 0 so repeated calls doesn't trigger database calls - - -*1.10.1* (20th April, 2005) - -* Fixed frivilous database queries being triggered with eager loading on empty associations and other things - -* Fixed order of loading in eager associations - -* Fixed stray comma when using eager loading and ordering together from has_many associations #1143 - - -*1.10.0* (19th April, 2005) - -* Added eager loading of associations as a way to solve the N+1 problem more gracefully without piggy-back queries. Example: - - for post in Post.find(:all, :limit => 100) - puts "Post: " + post.title - puts "Written by: " + post.author.name - puts "Last comment on: " + post.comments.first.created_on - end - - This used to generate 301 database queries if all 100 posts had both author and comments. It can now be written as: - - for post in Post.find(:all, :limit => 100, :include => [ :author, :comments ]) - - ...and the number of database queries needed is now 1. - -* Added new unified Base.find API and deprecated the use of find_first and find_all. See the documentation for Base.find. Examples: - - Person.find(1, :conditions => "administrator = 1", :order => "created_on DESC") - Person.find(1, 5, 6, :conditions => "administrator = 1", :order => "created_on DESC") - Person.find(:first, :order => "created_on DESC", :offset => 5) - Person.find(:all, :conditions => [ "category IN (?)", categories], :limit => 50) - Person.find(:all, :offset => 10, :limit => 10) - -* Added acts_as_nested_set #1000 [wschenk]. Introduction: - - This acts provides Nested Set functionality. Nested Set is similiar to Tree, but with - the added feature that you can select the children and all of it's descendants with - a single query. A good use case for this is a threaded post system, where you want - to display every reply to a comment without multiple selects. - -* Added Base.save! that attempts to save the record just like Base.save but will raise a RecordInvalid exception instead of returning false if the record is not valid [Dave Thomas] - -* Fixed PostgreSQL usage of fixtures with regards to public schemas and table names with dots #962 [gnuman1@gmail.com] - -* Fixed that fixtures were being deleted in the same order as inserts causing FK errors #890 [andrew.john.peters@gmail.com] - -* Fixed loading of fixtures in to be in the right order (or PostgreSQL would bark) #1047 [stephenh@chase3000.com] - -* Fixed page caching for non-vhost applications living underneath the root #1004 [Ben Schumacher] - -* Fixes a problem with the SQL Adapter which was resulting in IDENTITY_INSERT not being set to ON when it should be #1104 [adelle] - -* Added the option to specify the acceptance string in validates_acceptance_of #1106 [caleb@aei-tech.com] - -* Added insert_at(position) to acts_as_list #1083 [DeLynnB] - -* Removed the default order by id on has_and_belongs_to_many queries as it could kill performance on large sets (you can still specify by hand with :order) - -* Fixed that Base.silence should restore the old logger level when done, not just set it to DEBUG #1084 [yon@milliped.com] - -* Fixed boolean saving on Oracle #1093 [mparrish@pearware.org] - -* Moved build_association and create_association for has_one and belongs_to out of deprecation as they work when the association is nil unlike association.build and association.create, which require the association to be already in place #864 - -* Added rollbacks of transactions if they're active as the dispatcher is killed gracefully (TERM signal) #1054 [Leon Bredt] - -* Added quoting of column names for fixtures #997 [jcfischer@gmail.com] - -* Fixed counter_sql when no records exist in database for PostgreSQL (would give error, not 0) #1039 [Caleb Tennis] - -* Fixed that benchmarking times for rendering included db runtimes #987 [Stefan Kaes] - -* Fixed boolean queries for t/f fields in PostgreSQL #995 [dave@cherryville.org] - -* Added that model.items.delete(child) will delete the child, not just set the foreign key to nil, if the child is dependent on the model #978 [Jeremy Kemper] - -* Fixed auto-stamping of dates (created_on/updated_on) for PostgreSQL #985 [dave@cherryville.org] - -* Fixed Base.silence/benchmark to only log if a logger has been configured #986 [Stefan Kaes] - -* Added a join parameter as the third argument to Base.find_first and as the second to Base.count #426, #988 [Stefan Kaes] - -* Fixed bug in Base#hash method that would treat records with the same string-based id as different [Dave Thomas] - -* Renamed DateHelper#distance_of_time_in_words_to_now to DateHelper#time_ago_in_words (old method name is still available as a deprecated alias) - - -*1.9.1* (27th March, 2005) - -* Fixed that Active Record objects with float attribute could not be cloned #808 - -* Fixed that MissingSourceFile's wasn't properly detected in production mode #925 [Nicholas Seckar] - -* Fixed that :counter_cache option would look for a line_items_count column for a LineItem object instead of lineitems_count - -* Fixed that AR exists?() would explode on postgresql if the passed id did not match the PK type #900 [Scott Barron] - -* Fixed the MS SQL adapter to work with the new limit/offset approach and with binary data (still suffering from 7KB limit, though) #901 [delynnb] - - -*1.9.0* (22th March, 2005) - -* Added adapter independent limit clause as a two-element array with the first being the limit, the second being the offset #795 [Sam Stephenson]. Example: - - Developer.find_all nil, 'id ASC', 5 # return the first five developers - Developer.find_all nil, 'id ASC', [3, 8] # return three developers, starting from #8 and forward - - This doesn't yet work with the DB2 or MS SQL adapters. Patches to make that happen are encouraged. - -* Added alias_method :to_param, :id to Base, such that Active Record objects to be used as URL parameters in Action Pack automatically #812 [Nicholas Seckar/Sam Stephenson] - -* Improved the performance of the OCI8 adapter for Oracle #723 [pilx/gjenkins] - -* Added type conversion before saving a record, so string-based values like "10.0" aren't left for the database to convert #820 [dave@cherryville.org] - -* Added with additional settings for working with transactional fixtures and pre-loaded test databases #865 [mindel] - -* Fixed acts_as_list to trigger remove_from_list on destroy after the fact, not before, so a unique position can be maintained #871 [Alisdair McDiarmid] - -* Added the possibility of specifying fixtures in multiple calls #816 [kim@tinker.com] - -* Added Base.exists?(id) that'll return true if an object of the class with the given id exists #854 [stian@grytoyr.net] - -* Added optionally allow for nil or empty strings with validates_numericality_of #801 [Sebastian Kanthak] - -* Fixed problem with using slashes in validates_format_of regular expressions #801 [Sebastian Kanthak] - -* Fixed that SQLite3 exceptions are caught and reported properly #823 [yerejm] - -* Added that all types of after_find/after_initialized callbacks are triggered if the explicit implementation is present, not only the explicit implementation itself - -* Fixed that symbols can be used on attribute assignment, like page.emails.create(:subject => data.subject, :body => data.body) - - -*1.8.0* (7th March, 2005) - -* Added ActiveRecord::Base.colorize_logging to control whether to use colors in logs or not (on by default) - -* Added support for timestamp with time zone in PostgreSQL #560 [Scott Barron] - -* Added MultiparameterAssignmentErrors and AttributeAssignmentError exceptions #777 [demetrius]. Documentation: - - * +MultiparameterAssignmentErrors+ -- collection of errors that occurred during a mass assignment using the - +attributes=+ method. The +errors+ property of this exception contains an array of +AttributeAssignmentError+ - objects that should be inspected to determine which attributes triggered the errors. - * +AttributeAssignmentError+ -- an error occurred while doing a mass assignment through the +attributes=+ method. - You can inspect the +attribute+ property of the exception object to determine which attribute triggered the error. - -* Fixed that postgresql adapter would fails when reading bytea fields with null value #771 [rodrigo k] - -* Added transactional fixtures that uses rollback to undo changes to fixtures instead of DELETE/INSERT -- it's much faster. See documentation under Fixtures #760 [Jeremy Kemper] - -* Added destruction of dependent objects in has_one associations when a new assignment happens #742 [mindel]. Example: - - class Account < ActiveRecord::Base - has_one :credit_card, :dependent => true - end - class CreditCard < ActiveRecord::Base - belongs_to :account - end - - account.credit_card # => returns existing credit card, lets say id = 12 - account.credit_card = CreditCard.create("number" => "123") - account.save # => CC with id = 12 is destroyed - - -* Added validates_numericality_of #716 [Sebastian Kanthak/Chris McGrath]. Docuemntation: - - Validates whether the value of the specified attribute is numeric by trying to convert it to - a float with Kernel.Float (if integer is false) or applying it to the regular expression - /^[\+\-]?\d+$/ (if integer is set to true). - - class Person < ActiveRecord::Base - validates_numericality_of :value, :on => :create - end - - Configuration options: - * message - A custom error message (default is: "is not a number") - * on Specifies when this validation is active (default is :save, other options :create, :update) - * only_integer Specifies whether the value has to be an integer, e.g. an integral value (default is false) - - -* Fixed that HasManyAssociation#count was using :finder_sql rather than :counter_sql if it was available #445 [Scott Barron] - -* Added better defaults for composed_of, so statements like composed_of :time_zone, :mapping => %w( time_zone time_zone ) can be written without the mapping part (it's now assumed) - -* Added MacroReflection#macro which will return a symbol describing the macro used (like :composed_of or :has_many) #718, #248 [james@slashetc.com] - - -*1.7.0* (24th February, 2005) - -* Changed the auto-timestamping feature to use ActiveRecord::Base.default_timezone instead of entertaining the parallel ActiveRecord::Base.timestamps_gmt method. The latter is now deprecated and will throw a warning on use (but still work) #710 [Jamis Buck] - -* Added a OCI8-based Oracle adapter that has been verified to work with Oracle 8 and 9 #629 [Graham Jenkins]. Usage notes: - - 1. Key generation uses a sequence "rails_sequence" for all tables. (I couldn't find a simple - and safe way of passing table-specific sequence information to the adapter.) - 2. Oracle uses DATE or TIMESTAMP datatypes for both dates and times. Consequently I have had to - resort to some hacks to get data converted to Date or Time in Ruby. - If the column_name ends in _at (like created_at, updated_at) it's created as a Ruby Time. Else if the - hours/minutes/seconds are 0, I make it a Ruby Date. Else it's a Ruby Time. - This is nasty - but if you use Duck Typing you'll probably not care very much. - In 9i it's tempting to map DATE to Date and TIMESTAMP to Time but I don't think that is - valid - too many databases use DATE for both. - Timezones and sub-second precision on timestamps are not supported. - 3. Default values that are functions (such as "SYSDATE") are not supported. This is a - restriction of the way active record supports default values. - 4. Referential integrity constraints are not fully supported. Under at least - some circumstances, active record appears to delete parent and child records out of - sequence and out of transaction scope. (Or this may just be a problem of test setup.) - - The OCI8 driver can be retrieved from http://rubyforge.org/projects/ruby-oci8/ - -* Added option :schema_order to the PostgreSQL adapter to support the use of multiple schemas per database #697 [YuriSchimke] - -* Optimized the SQL used to generate has_and_belongs_to_many queries by listing the join table first #693 [yerejm] - -* Fixed that when using validation macros with a custom message, if you happened to use single quotes in the message string you would get a parsing error #657 [tonka] - -* Fixed that Active Record would throw Broken Pipe errors with FCGI when the MySQL connection timed out instead of reconnecting #428 [Nicholas Seckar] - -* Added options to specify an SSL connection for MySQL. Define the following attributes in the connection config (config/database.yml in Rails) to use it: sslkey, sslcert, sslca, sslcapath, sslcipher. To use SSL with no client certs, just set :sslca = '/dev/null'. http://dev.mysql.com/doc/mysql/en/secure-connections.html #604 [daniel@nightrunner.com] - -* Added automatic dropping/creating of test tables for running the unit tests on all databases #587 [adelle@bullet.net.au] - -* Fixed that find_by_* would fail when column names had numbers #670 [demetrius] - -* Fixed the SQL Server adapter on a bunch of issues #667 [DeLynn] - - 1. Created a new columns method that is much cleaner. - 2. Corrected a problem with the select and select_all methods - that didn't account for the LIMIT clause being passed into raw SQL statements. - 3. Implemented the string_to_time method in order to create proper instances of the time class. - 4. Added logic to the simplified_type method that allows the database to specify the scale of float data. - 5. Adjusted the quote_column_name to account for the fact that MS SQL is bothered by a forward slash in the data string. - -* Fixed that the dynamic finder like find_all_by_something_boolean(false) didn't work #649 [lmarlow] - -* Added validates_each that validates each specified attribute against a block #610 [Jeremy Kemper]. Example: - - class Person < ActiveRecord::Base - validates_each :first_name, :last_name do |record, attr| - record.errors.add attr, 'starts with z.' if attr[0] == ?z - end - end - -* Added :allow_nil as an explicit option for validates_length_of, so unless that's set to true having the attribute as nil will also return an error if a range is specified as :within #610 [Jeremy Kemper] - -* Added that validates_* now accept blocks to perform validations #618 [Tim Bates]. Example: - - class Person < ActiveRecord::Base - validate { |person| person.errors.add("title", "will never be valid") if SHOULD_NEVER_BE_VALID } - end - -* Addded validation for validate all the associated objects before declaring failure with validates_associated #618 [Tim Bates] - -* Added keyword-style approach to defining the custom relational bindings #545 [Jamis Buck]. Example: - - class Project < ActiveRecord::Base - primary_key "sysid" - table_name "XYZ_PROJECT" - inheritance_column { original_inheritance_column + "_id" } - end - -* Fixed Base#clone for use with PostgreSQL #565 [hanson@surgery.wisc.edu] - - -*1.6.0* (January 25th, 2005) - -* Added that has_many association build and create methods can take arrays of record data like Base#create and Base#build to build/create multiple records at once. - -* Added that Base#delete and Base#destroy both can take an array of ids to delete/destroy #336 - -* Added the option of supplying an array of attributes to Base#create, so that multiple records can be created at once. - -* Added the option of supplying an array of ids and attributes to Base#update, so that multiple records can be updated at once (inspired by #526/Duane Johnson). Example - - people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy"} } - Person.update(people.keys, people.values) - -* Added ActiveRecord::Base.timestamps_gmt that can be set to true to make the automated timestamping use GMT instead of local time #520 [Scott Baron] - -* Added that update_all calls sanitize_sql on its updates argument, so stuff like MyRecord.update_all(['time = ?', Time.now]) works #519 [notahat] - -* Fixed that the dynamic finders didn't treat nil as a "IS NULL" but rather "= NULL" case #515 [Demetrius] - -* Added bind-named arrays for interpolating a group of ids or strings in conditions #528 [Jeremy Kemper] - -* Added that has_and_belongs_to_many associations with additional attributes also can be created between unsaved objects and only committed to the database when Base#save is called on the associator #524 [Eric Anderson] - -* Fixed that records fetched with piggy-back attributes or through rich has_and_belongs_to_many associations couldn't be saved due to the extra attributes not part of the table #522 [Eric Anderson] - -* Added mass-assignment protection for the inheritance column -- regardless of a custom column is used or not - -* Fixed that association proxies would fail === tests like PremiumSubscription === @account.subscription - -* Fixed that column aliases didn't work as expected with the new MySql411 driver #507 [Demetrius] - -* Fixed that find_all would produce invalid sql when called sequentialy #490 [Scott Baron] - - -*1.5.1* (January 18th, 2005) - -* Fixed that the belongs_to and has_one proxy would fail a test like 'if project.manager' -- this unfortunately also means that you can't call methods like project.manager.build unless there already is a manager on the project #492 [Tim Bates] - -* Fixed that the Ruby/MySQL adapter wouldn't connect if the password was empty #503 [Pelle] - - -*1.5.0* (January 17th, 2005) - -* Fixed that unit tests for MySQL are now run as the "rails" user instead of root #455 [Eric Hodel] - -* Added validates_associated that enables validation of objects in an unsaved association #398 [Tim Bates]. Example: - - class Book < ActiveRecord::Base - has_many :pages - belongs_to :library - - validates_associated :pages, :library - end - -* Added support for associating unsaved objects #402 [Tim Bates]. Rules that govern this addition: - - == Unsaved objects and associations - - You can manipulate objects and associations before they are saved to the database, but there is some special behaviour you should be - aware of, mostly involving the saving of associated objects. - - === One-to-one associations - - * Assigning an object to a has_one association automatically saves that object, and the object being replaced (if there is one), in - order to update their primary keys - except if the parent object is unsaved (new_record? == true). - * If either of these saves fail (due to one of the objects being invalid) the assignment statement returns false and the assignment - is cancelled. - * If you wish to assign an object to a has_one association without saving it, use the #association.build method (documented below). - * Assigning an object to a belongs_to association does not save the object, since the foreign key field belongs on the parent. It does - not save the parent either. - - === Collections - - * Adding an object to a collection (has_many or has_and_belongs_to_many) automatically saves that object, except if the parent object - (the owner of the collection) is not yet stored in the database. - * If saving any of the objects being added to a collection (via #push or similar) fails, then #push returns false. - * You can add an object to a collection without automatically saving it by using the #collection.build method (documented below). - * All unsaved (new_record? == true) members of the collection are automatically saved when the parent is saved. - -* Added replace to associations, so you can do project.manager.replace(new_manager) or project.milestones.replace(new_milestones) #402 [Tim Bates] - -* Added build and create methods to has_one and belongs_to associations, so you can now do project.manager.build(attributes) #402 [Tim Bates] - -* Added that if a before_* callback returns false, all the later callbacks and the associated action are cancelled. If an after_* callback returns false, all the later callbacks are cancelled. Callbacks are generally run in the order they are defined, with the exception of callbacks defined as methods on the model, which are called last. #402 [Tim Bates] - -* Fixed that Base#== wouldn't work for multiple references to the same unsaved object #402 [Tim Bates] - -* Fixed binary support for PostgreSQL #444 [alex@byzantine.no] - -* Added a differenciation between AssociationCollection#size and -length. Now AssociationCollection#size returns the size of the - collection by executing a SELECT COUNT(*) query if the collection hasn't been loaded and calling collection.size if it has. If - it's more likely than not that the collection does have a size larger than zero and you need to fetch that collection afterwards, - it'll take one less SELECT query if you use length. - -* Added Base#attributes that returns a hash of all the attributes with their names as keys and clones of their objects as values #433 [atyp.de] - -* Fixed that foreign keys named the same as the association would cause stack overflow #437 [Eric Anderson] - -* Fixed default scope of acts_as_list from "1" to "1 = 1", so it'll work in PostgreSQL (among other places) #427 [Alexey] - -* Added Base#reload that reloads the attributes of an object from the database #422 [Andreas Schwarz] - -* Added SQLite3 compatibility through the sqlite3-ruby adapter by Jamis Buck #381 [Jeremy Kemper] - -* Added support for the new protocol spoken by MySQL 4.1.1+ servers for the Ruby/MySQL adapter that ships with Rails #440 [Matt Mower] - -* Added that Observers can use the observes class method instead of overwriting self.observed_class(). - - Before: - class ListSweeper < ActiveRecord::Base - def self.observed_class() [ List, Item ] - end - - After: - class ListSweeper < ActiveRecord::Base - observes List, Item - end - -* Fixed that conditions in has_many and has_and_belongs_to_many should be interpolated just like the finder_sql is - -* Fixed Base#update_attribute to be indifferent to whether a string or symbol is used to describe the name - -* Added Base#toggle(attribute) and Base#toggle!(attribute) that makes it easier to flip a switch or flag. - - Before: topic.update_attribute(:approved, !approved?) - After : topic.toggle!(:approved) - -* Added Base#increment!(attribute) and Base#decrement!(attribute) that also saves the records. Example: - - page.views # => 1 - page.increment!(:views) # executes an UPDATE statement - page.views # => 2 - - page.increment(:views).increment!(:views) - page.views # => 4 - -* Added Base#increment(attribute) and Base#decrement(attribute) that encapsulates the += 1 and -= 1 patterns. - - - - -*1.14.2* (April 9th, 2005) - -* Fixed calculations for the Oracle Adapter (closes #4626) [Michael Schoen] - - -*1.14.1* (April 6th, 2006) - -* Fix type_name_with_module to handle type names that begin with '::'. Closes #4614. [Nicholas Seckar] - -* Fixed that that multiparameter assignment doesn't work with aggregations (closes #4620) [Lars Pind] - -* Enable Limit/Offset in Calculations (closes #4558) [lmarlow] - -* Fixed that loading including associations returns all results if Load IDs For Limited Eager Loading returns none (closes #4528) [Rick Olson] - -* Fixed HasManyAssociation#find bugs when :finder_sql is set #4600 [lagroue@free.fr] - -* Allow AR::Base#respond_to? to behave when @attributes is nil [Ryan Davis] - -* Support eager includes when going through a polymorphic has_many association. [Rick Olson] - -* Added support for eagerly including polymorphic has_one associations. (closes #4525) [Rick Olson] - - class Post < ActiveRecord::Base - has_one :tagging, :as => :taggable - end - - Post.find :all, :include => :tagging - -* Added descriptive error messages for invalid has_many :through associations: going through :has_one or :has_and_belongs_to_many [Rick Olson] - -* Added support for going through a polymorphic has_many association: (closes #4401) [Rick Olson] - - class PhotoCollection < ActiveRecord::Base - has_many :photos, :as => :photographic - belongs_to :firm - end - - class Firm < ActiveRecord::Base - has_many :photo_collections - has_many :photos, :through => :photo_collections - end - -* Multiple fixes and optimizations in PostgreSQL adapter, allowing ruby-postgres gem to work properly. [ruben.nine@gmail.com] - -* Fixed that AssociationCollection#delete_all should work even if the records of the association are not loaded yet. [Florian Weber] - -* Changed those private ActiveRecord methods to take optional third argument :auto instead of nil for performance optimizations. (closes #4456) [Stefan] - -* Private ActiveRecord methods add_limit!, add_joins!, and add_conditions! take an OPTIONAL third argument 'scope' (closes #4456) [Rick Olson] - -* DEPRECATED: Using additional attributes on has_and_belongs_to_many associations. Instead upgrade your association to be a real join model [David Heinemeier Hansson] - -* Fixed that records returned from has_and_belongs_to_many associations with additional attributes should be marked as read only (fixes #4512) [David Heinemeier Hansson] - -* Do not implicitly mark recordss of has_many :through as readonly but do mark habtm records as readonly (eventually only on join tables without rich attributes). [Marcel Mollina Jr.] - -* Fixed broken OCIAdapter #4457 [Michael Schoen] - - -*1.14.0* (March 27th, 2006) - -* Replace 'rescue Object' with a finer grained rescue. Closes #4431. [Nicholas Seckar] - -* Fixed eager loading so that an aliased table cannot clash with a has_and_belongs_to_many join table [Rick Olson] - -* Add support for :include to with_scope [andrew@redlinesoftware.com] - -* Support the use of public synonyms with the Oracle adapter; required ruby-oci8 v0.1.14 #4390 [Michael Schoen] - -* Change periods (.) in table aliases to _'s. Closes #4251 [jeff@ministrycentered.com] - -* Changed has_and_belongs_to_many join to INNER JOIN for Mysql 3.23.x. Closes #4348 [Rick Olson] - -* Fixed issue that kept :select options from being scoped [Rick Olson] - -* Fixed db_schema_import when binary types are present #3101 [David Heinemeier Hansson] - -* Fixed that MySQL enums should always be returned as strings #3501 [David Heinemeier Hansson] - -* Change has_many :through to use the :source option to specify the source association. :class_name is now ignored. [Rick Olson] - - class Connection < ActiveRecord::Base - belongs_to :user - belongs_to :channel - end - - class Channel < ActiveRecord::Base - has_many :connections - has_many :contacts, :through => :connections, :class_name => 'User' # OLD - has_many :contacts, :through => :connections, :source => :user # NEW - end - -* Fixed DB2 adapter so nullable columns will be determines correctly now and quotes from column default values will be removed #4350 [contact@maik-schmidt.de] - -* Allow overriding of find parameters in scoped has_many :through calls [Rick Olson] - - In this example, :include => false disables the default eager association from loading. :select changes the standard - select clause. :joins specifies a join that is added to the end of the has_many :through query. - - class Post < ActiveRecord::Base - has_many :tags, :through => :taggings, :include => :tagging do - def add_joins_and_select - find :all, :select => 'tags.*, authors.id as author_id', :include => false, - :joins => 'left outer join posts on taggings.taggable_id = posts.id left outer join authors on posts.author_id = authors.id' - end - end - end - -* Fixed that schema changes while the database was open would break any connections to an SQLite database (now we reconnect if that error is throw) [David Heinemeier Hansson] - -* Don't classify the has_one class when eager loading, it is already singular. Add tests. (closes #4117) [Jonathan Viney] - -* Quit ignoring default :include options in has_many :through calls [Mark James] - -* Allow has_many :through associations to find the source association by setting a custom class (closes #4307) [Jonathan Viney] - -* Eager Loading support added for has_many :through => :has_many associations (see below). [Rick Olson] - -* Allow has_many :through to work on has_many associations (closes #3864) [sco@scottraymond.net] Example: - - class Firm < ActiveRecord::Base - has_many :clients - has_many :invoices, :through => :clients - end - - class Client < ActiveRecord::Base - belongs_to :firm - has_many :invoices - end - - class Invoice < ActiveRecord::Base - belongs_to :client - end - -* Raise error when trying to select many polymorphic objects with has_many :through or :include (closes #4226) [Josh Susser] - -* Fixed has_many :through to include :conditions set on the :through association. closes #4020 [Jonathan Viney] - -* Fix that has_many :through honors the foreign key set by the belongs_to association in the join model (closes #4259) [andylien@gmail.com / Rick Olson] - -* SQL Server adapter gets some love #4298 [Ryan Tomayko] - -* Added OpenBase database adapter that builds on top of the http://www.spice-of-life.net/ruby-openbase/ driver. All functionality except LIMIT/OFFSET is supported #3528 [derrickspell@cdmplus.com] - -* Rework table aliasing to account for truncated table aliases. Add smarter table aliasing when doing eager loading of STI associations. This allows you to use the association name in the order/where clause. [Jonathan Viney / Rick Olson] #4108 Example (SpecialComment is using STI): - - Author.find(:all, :include => { :posts => :special_comments }, :order => 'special_comments.body') - -* Add AbstractAdapter#table_alias_for to create table aliases according to the rules of the current adapter. [Rick Olson] - -* Provide access to the underlying database connection through Adapter#raw_connection. Enables the use of db-specific methods without complicating the adapters. #2090 [Michael Koziarski] - -* Remove broken attempts at handling columns with a default of 'now()' in the postgresql adapter. #2257 [Michael Koziarski] - -* Added connection#current_database that'll return of the current database (only works in MySQL, SQL Server, and Oracle so far -- please help implement for the rest of the adapters) #3663 [Tom Ward] - -* Fixed that Migration#execute would have the table name prefix appended to its query #4110 [mark.imbriaco@pobox.com] - -* Make all tinyint(1) variants act like boolean in mysql (tinyint(1) unsigned, etc.) [Jamis Buck] - -* Use association's :conditions when eager loading. [Jeremy Evans] #4144 - -* Alias the has_and_belongs_to_many join table on eager includes. #4106 [Jeremy Evans] - - This statement would normally error because the projects_developers table is joined twice, and therefore joined_on would be ambiguous. - - Developer.find(:all, :include => {:projects => :developers}, :conditions => 'join_project_developers.joined_on IS NOT NULL') - -* Oracle adapter gets some love #4230 [Michael Schoen] - - * Changes :text to CLOB rather than BLOB [Moses Hohman] - * Fixes an issue with nil numeric length/scales (several) - * Implements support for XMLTYPE columns [wilig / Kubo Takehiro] - * Tweaks a unit test to get it all green again - * Adds support for #current_database - -* Added Base.abstract_class? that marks which classes are not part of the Active Record hierarchy #3704 [Rick Olson] - - class CachedModel < ActiveRecord::Base - self.abstract_class = true - end - - class Post < CachedModel - end - - CachedModel.abstract_class? - => true - - Post.abstract_class? - => false - - Post.base_class - => Post - - Post.table_name - => 'posts' - -* Allow :dependent options to be used with polymorphic joins. #3820 [Rick Olson] - - class Foo < ActiveRecord::Base - has_many :attachments, :as => :attachable, :dependent => :delete_all - end - -* Nicer error message on has_many :through when :through reflection can not be found. #4042 [court3nay] - -* Upgrade to Transaction::Simple 1.3 [Jamis Buck] - -* Catch FixtureClassNotFound when using instantiated fixtures on a fixture that has no ActiveRecord model [Rick Olson] - -* Allow ordering of calculated results and/or grouped fields in calculations [solo@gatelys.com] - -* Make ActiveRecord::Base#save! return true instead of nil on success. #4173 [johan@johansorensen.com] - -* Dynamically set allow_concurrency. #4044 [Stefan Kaes] - -* Added Base#to_xml that'll turn the current record into a XML representation [David Heinemeier Hansson]. Example: - - topic.to_xml - - ...returns: - - - - The First Topic - David - 1 - false - 0 - 2000-01-01 08:28:00 - 2003-07-16 09:28:00 - Have a nice day - david@loudthinking.com - - 2004-04-15 - - - ...and you can configure with: - - topic.to_xml(:skip_instruct => true, :except => [ :id, bonus_time, :written_on, replies_count ]) - - ...that'll return: - - - The First Topic - David - false - Have a nice day - david@loudthinking.com - - 2004-04-15 - - - You can even do load first-level associations as part of the document: - - firm.to_xml :include => [ :account, :clients ] - - ...that'll return something like: - - - - 1 - 1 - 37signals - - - 1 - Summit - - - 1 - Microsoft - - - - 1 - 50 - - - -* Allow :counter_cache to take a column name for custom counter cache columns [Jamis Buck] - -* Documentation fixes for :dependent [robby@planetargon.com] - -* Stop the MySQL adapter crashing when views are present. #3782 [Jonathan Viney] - -* Don't classify the belongs_to class, it is already singular #4117 [keithm@infused.org] - -* Allow set_fixture_class to take Classes instead of strings for a class in a module. Raise FixtureClassNotFound if a fixture can't load. [Rick Olson] - -* Fix quoting of inheritance column for STI eager loading #4098 [Jonathan Viney ] - -* Added smarter table aliasing for eager associations for multiple self joins #3580 [Rick Olson] - - * The first time a table is referenced in a join, no alias is used. - * After that, the parent class name and the reflection name are used. - - Tree.find(:all, :include => :children) # LEFT OUTER JOIN trees AS tree_children ... - - * Any additional join references get a numerical suffix like '_2', '_3', etc. - -* Fixed eager loading problems with single-table inheritance #3580 [Rick Olson]. Post.find(:all, :include => :special_comments) now returns all posts, and any special comments that the posts may have. And made STI work with has_many :through and polymorphic belongs_to. - -* Added cascading eager loading that allows for queries like Author.find(:all, :include=> { :posts=> :comments }), which will fetch all authors, their posts, and the comments belonging to those posts in a single query (using LEFT OUTER JOIN) #3913 [anna@wota.jp]. Examples: - - # cascaded in two levels - >> Author.find(:all, :include=>{:posts=>:comments}) - => authors - +- posts - +- comments - - # cascaded in two levels and normal association - >> Author.find(:all, :include=>[{:posts=>:comments}, :categorizations]) - => authors - +- posts - +- comments - +- categorizations - - # cascaded in two levels with two has_many associations - >> Author.find(:all, :include=>{:posts=>[:comments, :categorizations]}) - => authors - +- posts - +- comments - +- categorizations - - # cascaded in three levels - >> Company.find(:all, :include=>{:groups=>{:members=>{:favorites}}}) - => companies - +- groups - +- members - +- favorites - -* Make counter cache work when replacing an association #3245 [eugenol@gmail.com] - -* Make migrations verbose [Jamis Buck] - -* Make counter_cache work with polymorphic belongs_to [Jamis Buck] - -* Fixed that calling HasOneProxy#build_model repeatedly would cause saving to happen #4058 [anna@wota.jp] - -* Added Sybase database adapter that relies on the Sybase Open Client bindings (see http://raa.ruby-lang.org/project/sybase-ctlib) #3765 [John Sheets]. It's almost completely Active Record compliant (including migrations), but has the following caveats: - - * Does not support DATE SQL column types; use DATETIME instead. - * Date columns on HABTM join tables are returned as String, not Time. - * Insertions are potentially broken for :polymorphic join tables - * BLOB column access not yet fully supported - -* Clear stale, cached connections left behind by defunct threads. [Jeremy Kemper] - -* CHANGED DEFAULT: set ActiveRecord::Base.allow_concurrency to false. Most AR usage is in single-threaded applications. [Jeremy Kemper] - -* Renamed the "oci" adapter to "oracle", but kept the old name as an alias #4017 [Michael Schoen] - -* Fixed that Base.save should always return false if the save didn't succeed, including if it has halted by before_save's #1861, #2477 [David Heinemeier Hansson] - -* Speed up class -> connection caching and stale connection verification. #3979 [Stefan Kaes] - -* Add set_fixture_class to allow the use of table name accessors with models which use set_table_name. [Kevin Clark] - -* Added that fixtures to placed in subdirectories of the main fixture files are also loaded #3937 [dblack@wobblini.net] - -* Define attribute query methods to avoid method_missing calls. #3677 [Jonathan Viney] - -* ActiveRecord::Base.remove_connection explicitly closes database connections and doesn't corrupt the connection cache. Introducing the disconnect! instance method for the PostgreSQL, MySQL, and SQL Server adapters; implementations for the others are welcome. #3591 [Simon Stapleton, Tom Ward] - -* Added support for nested scopes #3407 [anna@wota.jp]. Examples: - - Developer.with_scope(:find => { :conditions => "salary > 10000", :limit => 10 }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (salary > 10000) LIMIT 10 - - # inner rule is used. (all previous parameters are ignored) - Developer.with_exclusive_scope(:find => { :conditions => "name = 'Jamis'" }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (name = 'Jamis') - end - - # parameters are merged - Developer.with_scope(:find => { :conditions => "name = 'Jamis'" }) do - Developer.find(:all) # => SELECT * FROM developers WHERE (( salary > 10000 ) AND ( name = 'Jamis' )) LIMIT 10 - end - end - -* Fixed db2 connection with empty user_name and auth options #3622 [phurley@gmail.com] - -* Fixed validates_length_of to work on UTF-8 strings by using characters instead of bytes #3699 [Masao Mutoh] - -* Fixed that reflections would bleed across class boundaries in single-table inheritance setups #3796 [Lars Pind] - -* Added calculations: Base.count, Base.average, Base.sum, Base.minimum, Base.maxmium, and the generic Base.calculate. All can be used with :group and :having. Calculations and statitics need no longer require custom SQL. #3958 [Rick Olson]. Examples: - - Person.average :age - Person.minimum :age - Person.maximum :age - Person.sum :salary, :group => :last_name - -* Renamed Errors#count to Errors#size but kept an alias for the old name (and included an alias for length too) #3920 [Luke Redpath] - -* Reflections don't attempt to resolve module nesting of association classes. Simplify type computation. [Jeremy Kemper] - -* Improved the Oracle OCI Adapter with better performance for column reflection (from #3210), fixes to migrations (from #3476 and #3742), tweaks to unit tests (from #3610), and improved documentation (from #2446) #3879 [Aggregated by schoenm@earthlink.net] - -* Fixed that the schema_info table used by ActiveRecord::Schema.define should respect table pre- and suffixes #3834 [rubyonrails@atyp.de] - -* Added :select option to Base.count that'll allow you to select something else than * to be counted on. Especially important for count queries using DISTINCT #3839 [Stefan Kaes] - -* Correct syntax error in mysql DDL, and make AAACreateTablesTest run first [Bob Silva] - -* Allow :include to be used with has_many :through associations #3611 [Michael Schoen] - -* PostgreSQL: smarter schema dumps using pk_and_sequence_for(table). #2920 [Blair Zajac] - -* SQLServer: more compatible limit/offset emulation. #3779 [Tom Ward] - -* Polymorphic join support for has_one associations (has_one :foo, :as => :bar) #3785 [Rick Olson] - -* PostgreSQL: correctly parse negative integer column defaults. #3776 [bellis@deepthought.org] - -* Fix problems with count when used with :include [Jeremy Hopple and Kevin Clark] - -* ActiveRecord::RecordInvalid now states which validations failed in its default error message [Tobias Lütke] - -* Using AssociationCollection#build with arrays of hashes should call build, not create [David Heinemeier Hansson] - -* Remove definition of reloadable? from ActiveRecord::Base to make way for new Reloadable code. [Nicholas Seckar] - -* Fixed schema handling for DB2 adapter that didn't work: an initial schema could be set, but it wasn't used when getting tables and indexes #3678 [Maik Schmidt] - -* Support the :column option for remove_index with the PostgreSQL adapter. #3661 [Shugo Maeda] - -* Add documentation for add_index and remove_index. #3600 [Manfred Stienstra ] - -* If the OCI library is not available, raise an exception indicating as much. #3593 [Michael Schoen] - -* Add explicit :order in finder tests as postgresql orders results differently by default. #3577. [Rick Olson] - -* Make dynamic finders honor additional passed in :conditions. #3569 [Oleg Pudeyev , Marcel Molina Jr.] - -* Show a meaningful error when the DB2 adapter cannot be loaded due to missing dependencies. [Nicholas Seckar] - -* Make .count work for has_many associations with multi line finder sql [Michael Schoen] - -* Add AR::Base.base_class for querying the ancestor AR::Base subclass [Jamis Buck] - -* Allow configuration of the column used for optimistic locking [wilsonb@gmail.com] - -* Don't hardcode 'id' in acts as list. [ror@philippeapril.com] - -* Fix date errors for SQLServer in association tests. #3406 [Kevin Clark] - -* Escape database name in MySQL adapter when creating and dropping databases. #3409 [anna@wota.jp] - -* Disambiguate table names for columns in validates_uniqueness_of's WHERE clause. #3423 [alex.borovsky@gmail.com] - -* .with_scope imposed create parameters now bypass attr_protected [Tobias Lütke] - -* Don't raise an exception when there are more keys than there are named bind variables when sanitizing conditions. [Marcel Molina Jr.] - -* Multiple enhancements and adjustments to DB2 adaptor. #3377 [contact@maik-schmidt.de] - -* Sanitize scoped conditions. [Marcel Molina Jr.] - -* Added option to Base.reflection_of_all_associations to specify a specific association to scope the call. For example Base.reflection_of_all_associations(:has_many) [David Heinemeier Hansson] - -* Added ActiveRecord::SchemaDumper.ignore_tables which tells SchemaDumper which tables to ignore. Useful for tables with funky column like the ones required for tsearch2. [Tobias Lütke] - -* SchemaDumper now doesn't fail anymore when there are unknown column types in the schema. Instead the table is ignored and a Comment is left in the schema.rb. [Tobias Lütke] - -* Fixed that saving a model with multiple habtm associations would only save the first one. #3244 [yanowitz-rubyonrails@quantumfoam.org, Florian Weber] - -* Fix change_column to work with PostgreSQL 7.x and 8.x. #3141 [wejn@box.cz, Rick Olson, Scott Barron] - -* removed :piggyback in favor of just allowing :select on :through associations. [Tobias Lütke] - -* made method missing delegation to class methods on relation target work on :through associations. [Tobias Lütke] - -* made .find() work on :through relations. [Tobias Lütke] - -* Fix typo in association docs. #3296. [Blair Zajac] - -* Fixed :through relations when using STI inherited classes would use the inherited class's name as foreign key on the join model [Tobias Lütke] - -*1.13.2* (December 13th, 2005) - -* Become part of Rails 1.0 - -* MySQL: allow encoding option for mysql.rb driver. [Jeremy Kemper] - -* Added option inheritance for find calls on has_and_belongs_to_many and has_many assosociations [David Heinemeier Hansson]. Example: - - class Post - has_many :recent_comments, :class_name => "Comment", :limit => 10, :include => :author - end - - post.recent_comments.find(:all) # Uses LIMIT 10 and includes authors - post.recent_comments.find(:all, :limit => nil) # Uses no limit but include authors - post.recent_comments.find(:all, :limit => nil, :include => nil) # Uses no limit and doesn't include authors - -* Added option to specify :group, :limit, :offset, and :select options from find on has_and_belongs_to_many and has_many assosociations [David Heinemeier Hansson] - -* MySQL: fixes for the bundled mysql.rb driver. #3160 [Justin Forder] - -* SQLServer: fix obscure optimistic locking bug. #3068 [kajism@yahoo.com] - -* SQLServer: support uniqueidentifier columns. #2930 [keithm@infused.org] - -* SQLServer: cope with tables names qualified by owner. #3067 [jeff@ministrycentered.com] - -* SQLServer: cope with columns with "desc" in the name. #1950 [Ron Lusk, Ryan Tomayko] - -* SQLServer: cope with primary keys with "select" in the name. #3057 [rdifrango@captechventures.com] - -* Oracle: active? performs a select instead of a commit. #3133 [Michael Schoen] - -* MySQL: more robust test for nullified result hashes. #3124 [Stefan Kaes] - -* Reloading an instance refreshes its aggregations as well as its associations. #3024 [François Beausoleil] - -* Fixed that using :include together with :conditions array in Base.find would cause NoMethodError #2887 [Paul Hammmond] - -* PostgreSQL: more robust sequence name discovery. #3087 [Rick Olson] - -* Oracle: use syntax compatible with Oracle 8. #3131 [Michael Schoen] - -* MySQL: work around ruby-mysql/mysql-ruby inconsistency with mysql.stat. Eliminate usage of mysql.ping because it doesn't guarantee reconnect. Explicitly close and reopen the connection instead. [Jeremy Kemper] - -* Added preliminary support for polymorphic associations [David Heinemeier Hansson] - -* Added preliminary support for join models [David Heinemeier Hansson] - -* Allow validate_uniqueness_of to be scoped by more than just one column. #1559. [jeremy@jthopple.com, Marcel Molina Jr.] - -* Firebird: active? and reconnect! methods for handling stale connections. #428 [Ken Kunz ] - -* Firebird: updated for FireRuby 0.4.0. #3009 [Ken Kunz ] - -* MySQL and PostgreSQL: active? compatibility with the pure-Ruby driver. #428 [Jeremy Kemper] - -* Oracle: active? check pings the database rather than testing the last command status. #428 [Michael Schoen] - -* SQLServer: resolve column aliasing/quoting collision when using limit or offset in an eager find. #2974 [kajism@yahoo.com] - -* Reloading a model doesn't lose track of its connection. #2996 [junk@miriamtech.com, Jeremy Kemper] - -* Fixed bug where using update_attribute after pushing a record to a habtm association of the object caused duplicate rows in the join table. #2888 [colman@rominato.com, Florian Weber, Michael Schoen] - -* MySQL, PostgreSQL: reconnect! also reconfigures the connection. Otherwise, the connection 'loses' its settings if it times out and is reconnected. #2978 [Shugo Maeda] - -* has_and_belongs_to_many: use JOIN instead of LEFT JOIN. [Jeremy Kemper] - -* MySQL: introduce :encoding option to specify the character set for client, connection, and results. Only available for MySQL 4.1 and later with the mysql-ruby driver. Do SHOW CHARACTER SET in mysql client to see available encodings. #2975 [Shugo Maeda] - -* Add tasks to create, drop and rebuild the MySQL and PostgreSQL test databases. [Marcel Molina Jr.] - -* Correct boolean handling in generated reader methods. #2945 [Don Park, Stefan Kaes] - -* Don't generate read methods for columns whose names are not valid ruby method names. #2946 [Stefan Kaes] - -* Document :force option to create_table. #2921 [Blair Zajac ] - -* Don't add the same conditions twice in has_one finder sql. #2916 [Jeremy Evans] - -* Rename Version constant to VERSION. #2802 [Marcel Molina Jr.] - -* Introducing the Firebird adapter. Quote columns and use attribute_condition more consistently. Setup guide: http://wiki.rubyonrails.com/rails/pages/Firebird+Adapter #1874 [Ken Kunz ] - -* SQLServer: active? and reconnect! methods for handling stale connections. #428 [kajism@yahoo.com, Tom Ward ] - -* Associations handle case-equality more consistently: item.parts.is_a?(Array) and item.parts === Array. #1345 [MarkusQ@reality.com] - -* SQLServer: insert uses given primary key value if not nil rather than SELECT @@IDENTITY. #2866 [kajism@yahoo.com, Tom Ward ] - -* Oracle: active? and reconnect! methods for handling stale connections. Optionally retry queries after reconnect. #428 [Michael Schoen ] - -* Correct documentation for Base.delete_all. #1568 [Newhydra] - -* Oracle: test case for column default parsing. #2788 [Michael Schoen ] - -* Update documentation for Migrations. #2861 [Tom Werner ] - -* When AbstractAdapter#log rescues an exception, attempt to detect and reconnect to an inactive database connection. Connection adapter must respond to the active? and reconnect! instance methods. Initial support for PostgreSQL, MySQL, and SQLite. Make certain that all statements which may need reconnection are performed within a logged block: for example, this means no avoiding log(sql, name) { } if @logger.nil? #428 [Jeremy Kemper] - -* Oracle: Much faster column reflection. #2848 [Michael Schoen ] - -* Base.reset_sequence_name analogous to reset_table_name (mostly useful for testing). Base.define_attr_method allows nil values. [Jeremy Kemper] - -* PostgreSQL: smarter sequence name defaults, stricter last_insert_id, warn on pk without sequence. [Jeremy Kemper] - -* PostgreSQL: correctly discover custom primary key sequences. #2594 [Blair Zajac , meadow.nnick@gmail.com, Jeremy Kemper] - -* SQLServer: don't report limits for unsupported field types. #2835 [Ryan Tomayko] - -* Include the Enumerable module in ActiveRecord::Errors. [Rick Bradley ] - -* Add :group option, correspond to GROUP BY, to the find method and to the has_many association. #2818 [rubyonrails@atyp.de] - -* Don't cast nil or empty strings to a dummy date. #2789 [Rick Bradley ] - -* acts_as_list plays nicely with inheritance by remembering the class which declared it. #2811 [rephorm@rephorm.com] - -* Fix sqlite adaptor's detection of missing dbfile or database declaration. [Nicholas Seckar] - -* Fixed acts_as_list for definitions without an explicit :order #2803 [Jonathan Viney] - -* Upgrade bundled ruby-mysql 0.2.4 with mysql411 shim (see #440) to ruby-mysql 0.2.6 with a patchset for 4.1 protocol support. Local change [301] is now a part of the main driver; reapplied local change [2182]. Removed GC.start from Result.free. [tommy@tmtm.org, akuroda@gmail.com, Doug Fales , Jeremy Kemper] - -* Correct handling of complex order clauses with SQL Server limit emulation. #2770 [Tom Ward , Matt B.] - -* Correct whitespace problem in Oracle default column value parsing. #2788 [rick@rickbradley.com] - -* Destroy associated has_and_belongs_to_many records after all before_destroy callbacks but before destroy. This allows you to act on the habtm association as you please while preserving referential integrity. #2065 [larrywilliams1@gmail.com, sam.kirchmeier@gmail.com, elliot@townx.org, Jeremy Kemper] - -* Deprecate the old, confusing :exclusively_dependent option in favor of :dependent => :delete_all. [Jeremy Kemper] - -* More compatible Oracle column reflection. #2771 [Ryan Davis , Michael Schoen ] - - -*1.13.0* (November 7th, 2005) - -* Fixed faulty regex in get_table_name method (SQLServerAdapter) #2639 [Ryan Tomayko] - -* Added :include as an option for association declarations [David Heinemeier Hansson]. Example: - - has_many :posts, :include => [ :author, :comments ] - -* Rename Base.constrain to Base.with_scope so it doesn't conflict with existing concept of database constraints. Make scoping more robust: uniform method => parameters, validated method names and supported finder parameters, raise exception on nested scopes. [Jeremy Kemper] Example: - - Comment.with_scope(:find => { :conditions => 'active=true' }, :create => { :post_id => 5 }) do - # Find where name = ? and active=true - Comment.find :all, :conditions => ['name = ?', name] - # Create comment associated with :post_id - Comment.create :body => "Hello world" - end - -* Fixed that SQL Server should ignore :size declarations on anything but integer and string in the agnostic schema representation #2756 [Ryan Tomayko] - -* Added constrain scoping for creates using a hash of attributes bound to the :creation key [David Heinemeier Hansson]. Example: - - Comment.constrain(:creation => { :post_id => 5 }) do - # Associated with :post_id - Comment.create :body => "Hello world" - end - - This is rarely used directly, but allows for find_or_create on associations. So you can do: - - # If the tag doesn't exist, a new one is created that's associated with the person - person.tags.find_or_create_by_name("Summer") - -* Added find_or_create_by_X as a second type of dynamic finder that'll create the record if it doesn't already exist [David Heinemeier Hansson]. Example: - - # No 'Summer' tag exists - Tag.find_or_create_by_name("Summer") # equal to Tag.create(:name => "Summer") - - # Now the 'Summer' tag does exist - Tag.find_or_create_by_name("Summer") # equal to Tag.find_by_name("Summer") - -* Added extension capabilities to has_many and has_and_belongs_to_many proxies [David Heinemeier Hansson]. Example: - - class Account < ActiveRecord::Base - has_many :people do - def find_or_create_by_name(name) - first_name, *last_name = name.split - last_name = last_name.join " " - - find_or_create_by_first_name_and_last_name(first_name, last_name) - end - end - end - - person = Account.find(:first).people.find_or_create_by_name("David Heinemeier Hansson") - person.first_name # => "David" - person.last_name # => "Heinemeier Hansson" - - Note that the anoymous module must be declared using brackets, not do/end (due to order of evaluation). - -* Omit internal dtproperties table from SQLServer table list. #2729 [Ryan Tomayko] - -* Quote column names in generated SQL. #2728 [Ryan Tomayko] - -* Correct the pure-Ruby MySQL 4.1.1 shim's version test. #2718 [Jeremy Kemper] - -* Add Model.create! to match existing model.save! method. When save! raises RecordInvalid, you can catch the exception, retrieve the invalid record (invalid_exception.record), and see its errors (invalid_exception.record.errors). [Jeremy Kemper] - -* Correct fixture behavior when table name pluralization is off. #2719 [Rick Bradley ] - -* Changed :dbfile to :database for SQLite adapter for consistency (old key still works as an alias) #2644 [Dan Peterson] - -* Added migration support for Oracle #2647 [Michael Schoen] - -* Worked around that connection can't be reset if allow_concurrency is off. #2648 [Michael Schoen ] - -* Fixed SQL Server adapter to pass even more tests and do even better #2634 [Ryan Tomayko] - -* Fixed SQL Server adapter so it honors options[:conditions] when applying :limits #1978 [Tom Ward] - -* Added migration support to SQL Server adapter (please someone do the same for Oracle and DB2) #2625 [Tom Ward] - -* Use AR::Base.silence rather than AR::Base.logger.silence in fixtures to preserve Log4r compatibility. #2618 [dansketcher@gmail.com] - -* Constraints are cloned so they can't be inadvertently modified while they're -in effect. Added :readonly finder constraint. Calling an association collection's class method (Part.foobar via item.parts.foobar) constrains :readonly => false since the collection's :joins constraint would otherwise force it to true. [Jeremy Kemper ] - -* Added :offset and :limit to the kinds of options that Base.constrain can use #2466 [duane.johnson@gmail.com] - -* Fixed handling of nil number columns on Oracle and cleaned up tests for Oracle in general #2555 [Michael Schoen] - -* Added quoted_true and quoted_false methods and tables to db2_adapter and cleaned up tests for DB2 #2493, #2624 [maik schmidt] - - -*1.12.2* (October 26th, 2005) - -* Allow symbols to rename columns when using SQLite adapter. #2531 [Kevin Clark] - -* Map Active Record time to SQL TIME. #2575, #2576 [Robby Russell ] - -* Clarify semantics of ActiveRecord::Base#respond_to? #2560 [Stefan Kaes] - -* Fixed Association#clear for associations which have not yet been accessed. #2524 [Patrick Lenz ] - -* HABTM finders shouldn't return readonly records. #2525 [Patrick Lenz ] - -* Make all tests runnable on their own. #2521. [Blair Zajac ] - - -*1.12.1* (October 19th, 2005) - -* Always parenthesize :conditions options so they may be safely combined with STI and constraints. - -* Correct PostgreSQL primary key sequence detection. #2507 [tmornini@infomania.com] - -* Added support for using limits in eager loads that involve has_many and has_and_belongs_to_many associations - - -*1.12.0* (October 16th, 2005) - -* Update/clean up documentation (rdoc) - -* PostgreSQL sequence support. Use set_sequence_name in your model class to specify its primary key sequence. #2292 [Rick Olson , Robby Russell ] - -* Change default logging colors to work on both white and black backgrounds. [Sam Stephenson] - -* YAML fixtures support ordered hashes for fixtures with foreign key dependencies in the same table. #1896 [purestorm@ggnore.net] - -* :dependent now accepts :nullify option. Sets the foreign key of the related objects to NULL instead of deleting them. #2015 [Robby Russell ] - -* Introduce read-only records. If you call object.readonly! then it will mark the object as read-only and raise ReadOnlyRecord if you call object.save. object.readonly? reports whether the object is read-only. Passing :readonly => true to any finder method will mark returned records as read-only. The :joins option now implies :readonly, so if you use this option, saving the same record will now fail. Use find_by_sql to work around. - -* Avoid memleak in dev mode when using fcgi - -* Simplified .clear on active record associations by using the existing delete_records method. #1906 [Caleb ] - -* Delegate access to a customized primary key to the conventional id method. #2444. [Blair Zajac ] - -* Fix errors caused by assigning a has-one or belongs-to property to itself - -* Add ActiveRecord::Base.schema_format setting which specifies how databases should be dumped [Sam Stephenson] - -* Update DB2 adapter. #2206. [contact@maik-schmidt.de] - -* Corrections to SQLServer native data types. #2267. [rails.20.clarry@spamgourmet.com] - -* Deprecated ActiveRecord::Base.threaded_connection in favor of ActiveRecord::Base.allow_concurrency. - -* Protect id attribute from mass assigment even when the primary key is set to something else. #2438.

(Use MysqlAdapter.emulate_booleans = false to disable this behavior) - -* Added new symbol-driven approach to activating observers with Base#observers= [David Heinemeier Hansson]. Example: - - ActiveRecord::Base.observers = :cacher, :garbage_collector - -* Added AbstractAdapter#select_value and AbstractAdapter#select_values as convenience methods for selecting single values, instead of hashes, of the first column in a SELECT #2283 [solo@gatelys.com] - -* Wrap :conditions in parentheses to prevent problems with OR's #1871 [Jamis Buck] - -* Allow the postgresql adapter to work with the SchemaDumper.

[Jamis Buck] - -* Fixed migrations for Windows when using more than 10 [David Naseby] - -* Fixed that the create_x method from belongs_to wouldn't save the association properly #2042 [Florian Weber] - -* Fixed saving a record with two unsaved belongs_to associations pointing to the same object #2023 [Tobias Lütke] - -* Improved migrations' behavior when the schema_info table is empty. [Nicholas Seckar] - -* Fixed that Observers didn't observe sub-classes #627 [Florian Weber] - -* Fix eager loading error messages, allow :include to specify tables using strings or symbols. Closes #2222 [Marcel Molina Jr.] - -* Added check for RAILS_CONNECTION_ADAPTERS on startup and only load the connection adapters specified within if its present (available in Rails through config.connection_adapters using the new config) #1958 [skae] - -* Fixed various problems with has_and_belongs_to_many when using customer finder_sql #2094 [Florian Weber] - -* Added better exception error when unknown column types are used with migrations #1814 [François Beausoleil] - -* Fixed "connection lost" issue with the bundled Ruby/MySQL driver (would kill the app after 8 hours of inactivity) #2163, #428 [kajism@yahoo.com] - -* Fixed comparison of Active Record objects so two new objects are not equal #2099 [deberg] - -* Fixed that the SQL Server adapter would sometimes return DBI::Timestamp objects instead of Time #2127 [Tom Ward] - -* Added the instance methods #root and #ancestors on acts_as_tree and fixed siblings to not include the current node #2142, #2140 [coffee2code] - -* Fixed that Active Record would call SHOW FIELDS twice (or more) for the same model when the cached results were available #1947 [sd@notso.net] - -* Added log_level and use_silence parameter to ActiveRecord::Base.benchmark. The first controls at what level the benchmark statement will be logged (now as debug, instead of info) and the second that can be passed false to include all logging statements during the benchmark block/ - -* Make sure the schema_info table is created before querying the current version #1903 - -* Fixtures ignore table name prefix and suffix #1987 [Jakob Skjerning] - -* Add documentation for index_type argument to add_index method for migrations #2005 [Blaine] - -* Modify read_attribute to allow a symbol argument #2024 [Ken Kunz] - -* Make destroy return self #1913 [Sebastian Kanthak] - -* Fix typo in validations documentation #1938 [court3nay] - -* Make acts_as_list work for insert_at(1) #1966 [hensleyl@papermountain.org] - -* Fix typo in count_by_sql documentation #1969 [Alexey Verkhovsky] - -* Allow add_column and create_table to specify NOT NULL #1712 [emptysands@gmail.com] - -* Fix create_table so that id column is implicitly added [Rick Olson] - -* Default sequence names for Oracle changed to #{table_name}_seq, which is the most commonly used standard. In addition, a new method ActiveRecord::Base#set_sequence_name allows the developer to set the sequence name per model. This is a non-backwards-compatible change -- anyone using the old-style "rails_sequence" will need to either create new sequences, or set: ActiveRecord::Base.set_sequence_name = "rails_sequence" #1798 - -* OCIAdapter now properly handles synonyms, which are commonly used to separate out the schema owner from the application user #1798 - -* Fixed the handling of camelCase columns names in Oracle #1798 - -* Implemented for OCI the Rakefile tasks of :clone_structure_to_test, :db_structure_dump, and :purge_test_database, which enable Oracle folks to enjoy all the agile goodness of Rails for testing. Note that the current implementation is fairly limited -- only tables and sequences are cloned, not constraints or indexes. A full clone in Oracle generally requires some manual effort, and is version-specific. Post 9i, Oracle recommends the use of the DBMS_METADATA package, though that approach requires editing of the physical characteristics generated #1798 - -* Fixed the handling of multiple blob columns in Oracle if one or more of them are null #1798 - -* Added support for calling constrained class methods on has_many and has_and_belongs_to_many collections #1764 [Tobias Lütke] - - class Comment < AR:B - def self.search(q) - find(:all, :conditions => ["body = ?", q]) - end - end - - class Post < AR:B - has_many :comments - end - - Post.find(1).comments.search('hi') # => SELECT * from comments WHERE post_id = 1 AND body = 'hi' - - NOTICE: This patch changes the underlying SQL generated by has_and_belongs_to_many queries. If your relying on that, such as - by explicitly referencing the old t and j aliases, you'll need to update your code. Of course, you _shouldn't_ be relying on - details like that no less than you should be diving in to touch private variables. But just in case you do, consider yourself - noticed :) - -* Added migration support for SQLite (using temporary tables to simulate ALTER TABLE) #1771 [Sam Stephenson] - -* Remove extra definition of supports_migrations? from abstract_adaptor.rb [Nicholas Seckar] - -* Fix acts_as_list so that moving next-to-last item to the bottom does not result in duplicate item positions - -* Fixed incompatibility in DB2 adapter with the new limit/offset approach #1718 [Maik Schmidt] - -* Added :select option to find which can specify a different value than the default *, like find(:all, :select => "first_name, last_name"), if you either only want to select part of the columns or exclude columns otherwise included from a join #1338 [Stefan Kaes] - - -*1.11.1* (11 July, 2005) - -* Added support for limit and offset with eager loading of has_one and belongs_to associations. Using the options with has_many and has_and_belongs_to_many associations will now raise an ActiveRecord::ConfigurationError #1692 [Rick Olson] - -* Fixed that assume_bottom_position (in acts_as_list) could be called on items already last in the list and they would move one position away from the list #1648 [tyler@kianta.com] - -* Added ActiveRecord::Base.threaded_connections flag to turn off 1-connection per thread (required for thread safety). By default it's on, but WEBrick in Rails need it off #1685 [Sam Stephenson] - -* Correct reflected table name for singular associations. #1688 [court3nay] - -* Fixed optimistic locking with SQL Server #1660 [tom@popdog.net] - -* Added ActiveRecord::Migrator.migrate that can figure out whether to go up or down based on the target version and the current - -* Added better error message for "packets out of order" #1630 [court3nay] - -* Fixed first run of "rake migrate" on PostgreSQL by not expecting a return value on the id #1640 - - -*1.11.0* (6 July, 2005) - -* Fixed that Yaml error message in fixtures hid the real error #1623 [Nicholas Seckar] - -* Changed logging of SQL statements to use the DEBUG level instead of INFO - -* Added new Migrations framework for describing schema transformations in a way that can be easily applied across multiple databases #1604 [Tobias Lütke] See documentation under ActiveRecord::Migration and the additional support in the Rails rakefile/generator. - -* Added callback hooks to association collections #1549 [Florian Weber]. Example: - - class Project - has_and_belongs_to_many :developers, :before_add => :evaluate_velocity - - def evaluate_velocity(developer) - ... - end - end - - ..raising an exception will cause the object not to be added (or removed, with before_remove). - - -* Fixed Base.content_columns call for SQL Server adapter #1450 [DeLynn Berry] - -* Fixed Base#write_attribute to work with both symbols and strings #1190 [Paul Legato] - -* Fixed that has_and_belongs_to_many didn't respect single table inheritance types #1081 [Florian Weber] - -* Speed up ActiveRecord#method_missing for the common case (read_attribute). - -* Only notify observers on after_find and after_initialize if these methods are defined on the model. #1235 [Stefan Kaes] - -* Fixed that single-table inheritance sub-classes couldn't be used to limit the result set with eager loading #1215 [Chris McGrath] - -* Fixed validates_numericality_of to work with overrided getter-method when :allow_nil is on #1316 [raidel@onemail.at] - -* Added roots, root, and siblings to the batch of methods added by acts_as_tree #1541 [Michael Schuerig] - -* Added support for limit/offset with the MS SQL Server driver so that pagination will now work #1569 [DeLynn Berry] - -* Added support for ODBC connections to MS SQL Server so you can connect from a non-Windows machine #1569 [Mark Imbriaco/DeLynn Berry] - -* Fixed that multiparameter posts ignored attr_protected #1532 [alec+rails@veryclever.net] - -* Fixed problem with eager loading when using a has_and_belongs_to_many association using :association_foreign_key #1504 [flash@vanklinkenbergsoftware.nl] - -* Fixed Base#find to honor the documentation on how :joins work and make them consistent with Base#count #1405 [pritchie@gmail.com]. What used to be: - - Developer.find :all, :joins => 'developers_projects', :conditions => 'id=developer_id AND project_id=1' - - ...should instead be: - - Developer.find( - :all, - :joins => 'LEFT JOIN developers_projects ON developers.id = developers_projects.developer_id', - :conditions => 'project_id=1' - ) - -* Fixed that validations didn't respecting custom setting for too_short, too_long messages #1437 [Marcel Molina Jr.] - -* Fixed that clear_association_cache doesn't delete new associations on new records (so you can safely place new records in the session with Action Pack without having new associations wiped) #1494 [cluon] - -* Fixed that calling Model.find([]) returns [] and doesn't throw an exception #1379 - -* Fixed that adding a record to a has_and_belongs_to collection would always save it -- now it only saves if its a new record #1203 [Alisdair McDiarmid] - -* Fixed saving of in-memory association structures to happen as a after_create/after_update callback instead of after_save -- that way you can add new associations in after_create/after_update callbacks without getting them saved twice - -* Allow any Enumerable, not just Array, to work as bind variables #1344 [Jeremy Kemper] - -* Added actual database-changing behavior to collection assigment for has_many and has_and_belongs_to_many #1425 [Sebastian Kanthak]. - Example: - - david.projects = [Project.find(1), Project.new("name" => "ActionWebSearch")] - david.save - - If david.projects already contain the project with ID 1, this is left unchanged. Any other projects are dropped. And the new - project is saved when david.save is called. - - Also included is a way to do assignments through IDs, which is perfect for checkbox updating, so you get to do: - - david.project_ids = [1, 5, 7] - -* Corrected typo in find SQL for has_and_belongs_to_many. #1312 [ben@bensinclair.com] - -* Fixed sanitized conditions for has_many finder method. #1281 [jackc@hylesanderson.com, pragdave, Tobias Lütke] - -* Comprehensive PostgreSQL schema support. Use the optional schema_search_path directive in database.yml to give a comma-separated list of schemas to search for your tables. This allows you, for example, to have tables in a shared schema without having to use a custom table name. See http://www.postgresql.org/docs/8.0/interactive/ddl-schemas.html to learn more. #827 [dave@cherryville.org] - -* Corrected @@configurations typo #1410 [david@ruppconsulting.com] - -* Return PostgreSQL columns in the order they were declared #1374 [perlguy@gmail.com] - -* Allow before/after update hooks to work on models using optimistic locking - -* Eager loading of dependent has_one associations won't delete the association #1212 - -* Added a second parameter to the build and create method for has_one that controls whether the existing association should be replaced (which means nullifying its foreign key as well). By default this is true, but false can be passed to prevent it. - -* Using transactional fixtures now causes the data to be loaded only once. - -* Added fixture accessor methods that can be used when instantiated fixtures are disabled. - - fixtures :web_sites - - def test_something - assert_equal "Ruby on Rails", web_sites(:rubyonrails).name - end - -* Added DoubleRenderError exception that'll be raised if render* is called twice #518 [Nicholas Seckar] - -* Fixed exceptions occuring after render has been called #1096 [Nicholas Seckar] - -* CHANGED: validates_presence_of now uses Errors#add_on_blank, which will make " " fail the validation where it didn't before #1309 - -* Added Errors#add_on_blank which works like Errors#add_on_empty, but uses Object#blank? instead - -* Added the :if option to all validations that can either use a block or a method pointer to determine whether the validation should be run or not. #1324 [Duane Johnson/jhosteny]. Examples: - - Conditional validations such as the following are made possible: - validates_numericality_of :income, :if => :employed? - - Conditional validations can also solve the salted login generator problem: - validates_confirmation_of :password, :if => :new_password? - - Using blocks: - validates_presence_of :username, :if => Proc.new { |user| user.signup_step > 1 } - -* Fixed use of construct_finder_sql when using :join #1288 [dwlt@dwlt.net] - -* Fixed that :delete_sql in has_and_belongs_to_many associations couldn't access record properties #1299 [Rick Olson] - -* Fixed that clone would break when an aggregate had the same name as one of its attributes #1307 [Jeremy Kemper] - -* Changed that destroying an object will only freeze the attributes hash, which keeps the object from having attributes changed (as that wouldn't make sense), but allows for the querying of associations after it has been destroyed. - -* Changed the callbacks such that observers are notified before the in-object callbacks are triggered. Without this change, it wasn't possible to act on the whole object in something like a before_destroy observer without having the objects own callbacks (like deleting associations) called first. - -* Added option for passing an array to the find_all version of the dynamic finders and have it evaluated as an IN fragment. Example: - - # SELECT * FROM topics WHERE title IN ('First', 'Second') - Topic.find_all_by_title(["First", "Second"]) - -* Added compatibility with camelCase column names for dynamic finders #533 [Dee Zsombor] - -* Fixed extraneous comma in count() function that made it not work with joins #1156 [Jarkko Laine/Dee Zsombor] - -* Fixed incompatibility with Base#find with an array of ids that would fail when using eager loading #1186 [Alisdair McDiarmid] - -* Fixed that validate_length_of lost :on option when :within was specified #1195 [jhosteny@mac.com] - -* Added encoding and min_messages options for PostgreSQL #1205 [Shugo Maeda]. Configuration example: - - development: - adapter: postgresql - database: rails_development - host: localhost - username: postgres - password: - encoding: UTF8 - min_messages: ERROR - -* Fixed acts_as_list where deleting an item that was removed from the list would ruin the positioning of other list items #1197 [Jamis Buck] - -* Added validates_exclusion_of as a negative of validates_inclusion_of - -* Optimized counting of has_many associations by setting the association to empty if the count is 0 so repeated calls doesn't trigger database calls - - -*1.10.1* (20th April, 2005) - -* Fixed frivilous database queries being triggered with eager loading on empty associations and other things - -* Fixed order of loading in eager associations - -* Fixed stray comma when using eager loading and ordering together from has_many associations #1143 - - -*1.10.0* (19th April, 2005) - -* Added eager loading of associations as a way to solve the N+1 problem more gracefully without piggy-back queries. Example: - - for post in Post.find(:all, :limit => 100) - puts "Post: " + post.title - puts "Written by: " + post.author.name - puts "Last comment on: " + post.comments.first.created_on - end - - This used to generate 301 database queries if all 100 posts had both author and comments. It can now be written as: - - for post in Post.find(:all, :limit => 100, :include => [ :author, :comments ]) - - ...and the number of database queries needed is now 1. - -* Added new unified Base.find API and deprecated the use of find_first and find_all. See the documentation for Base.find. Examples: - - Person.find(1, :conditions => "administrator = 1", :order => "created_on DESC") - Person.find(1, 5, 6, :conditions => "administrator = 1", :order => "created_on DESC") - Person.find(:first, :order => "created_on DESC", :offset => 5) - Person.find(:all, :conditions => [ "category IN (?)", categories], :limit => 50) - Person.find(:all, :offset => 10, :limit => 10) - -* Added acts_as_nested_set #1000 [wschenk]. Introduction: - - This acts provides Nested Set functionality. Nested Set is similiar to Tree, but with - the added feature that you can select the children and all of it's descendants with - a single query. A good use case for this is a threaded post system, where you want - to display every reply to a comment without multiple selects. - -* Added Base.save! that attempts to save the record just like Base.save but will raise a RecordInvalid exception instead of returning false if the record is not valid [Dave Thomas] - -* Fixed PostgreSQL usage of fixtures with regards to public schemas and table names with dots #962 [gnuman1@gmail.com] - -* Fixed that fixtures were being deleted in the same order as inserts causing FK errors #890 [andrew.john.peters@gmail.com] - -* Fixed loading of fixtures in to be in the right order (or PostgreSQL would bark) #1047 [stephenh@chase3000.com] - -* Fixed page caching for non-vhost applications living underneath the root #1004 [Ben Schumacher] - -* Fixes a problem with the SQL Adapter which was resulting in IDENTITY_INSERT not being set to ON when it should be #1104 [adelle] - -* Added the option to specify the acceptance string in validates_acceptance_of #1106 [caleb@aei-tech.com] - -* Added insert_at(position) to acts_as_list #1083 [DeLynnB] - -* Removed the default order by id on has_and_belongs_to_many queries as it could kill performance on large sets (you can still specify by hand with :order) - -* Fixed that Base.silence should restore the old logger level when done, not just set it to DEBUG #1084 [yon@milliped.com] - -* Fixed boolean saving on Oracle #1093 [mparrish@pearware.org] - -* Moved build_association and create_association for has_one and belongs_to out of deprecation as they work when the association is nil unlike association.build and association.create, which require the association to be already in place #864 - -* Added rollbacks of transactions if they're active as the dispatcher is killed gracefully (TERM signal) #1054 [Leon Bredt] - -* Added quoting of column names for fixtures #997 [jcfischer@gmail.com] - -* Fixed counter_sql when no records exist in database for PostgreSQL (would give error, not 0) #1039 [Caleb Tennis] - -* Fixed that benchmarking times for rendering included db runtimes #987 [Stefan Kaes] - -* Fixed boolean queries for t/f fields in PostgreSQL #995 [dave@cherryville.org] - -* Added that model.items.delete(child) will delete the child, not just set the foreign key to nil, if the child is dependent on the model #978 [Jeremy Kemper] - -* Fixed auto-stamping of dates (created_on/updated_on) for PostgreSQL #985 [dave@cherryville.org] - -* Fixed Base.silence/benchmark to only log if a logger has been configured #986 [Stefan Kaes] - -* Added a join parameter as the third argument to Base.find_first and as the second to Base.count #426, #988 [Stefan Kaes] - -* Fixed bug in Base#hash method that would treat records with the same string-based id as different [Dave Thomas] - -* Renamed DateHelper#distance_of_time_in_words_to_now to DateHelper#time_ago_in_words (old method name is still available as a deprecated alias) - - -*1.9.1* (27th March, 2005) - -* Fixed that Active Record objects with float attribute could not be cloned #808 - -* Fixed that MissingSourceFile's wasn't properly detected in production mode #925 [Nicholas Seckar] - -* Fixed that :counter_cache option would look for a line_items_count column for a LineItem object instead of lineitems_count - -* Fixed that AR exists?() would explode on postgresql if the passed id did not match the PK type #900 [Scott Barron] - -* Fixed the MS SQL adapter to work with the new limit/offset approach and with binary data (still suffering from 7KB limit, though) #901 [delynnb] - - -*1.9.0* (22th March, 2005) - -* Added adapter independent limit clause as a two-element array with the first being the limit, the second being the offset #795 [Sam Stephenson]. Example: - - Developer.find_all nil, 'id ASC', 5 # return the first five developers - Developer.find_all nil, 'id ASC', [3, 8] # return three developers, starting from #8 and forward - - This doesn't yet work with the DB2 or MS SQL adapters. Patches to make that happen are encouraged. - -* Added alias_method :to_param, :id to Base, such that Active Record objects to be used as URL parameters in Action Pack automatically #812 [Nicholas Seckar/Sam Stephenson] - -* Improved the performance of the OCI8 adapter for Oracle #723 [pilx/gjenkins] - -* Added type conversion before saving a record, so string-based values like "10.0" aren't left for the database to convert #820 [dave@cherryville.org] - -* Added with additional settings for working with transactional fixtures and pre-loaded test databases #865 [mindel] - -* Fixed acts_as_list to trigger remove_from_list on destroy after the fact, not before, so a unique position can be maintained #871 [Alisdair McDiarmid] - -* Added the possibility of specifying fixtures in multiple calls #816 [kim@tinker.com] - -* Added Base.exists?(id) that'll return true if an object of the class with the given id exists #854 [stian@grytoyr.net] - -* Added optionally allow for nil or empty strings with validates_numericality_of #801 [Sebastian Kanthak] - -* Fixed problem with using slashes in validates_format_of regular expressions #801 [Sebastian Kanthak] - -* Fixed that SQLite3 exceptions are caught and reported properly #823 [yerejm] - -* Added that all types of after_find/after_initialized callbacks are triggered if the explicit implementation is present, not only the explicit implementation itself - -* Fixed that symbols can be used on attribute assignment, like page.emails.create(:subject => data.subject, :body => data.body) - - -*1.8.0* (7th March, 2005) - -* Added ActiveRecord::Base.colorize_logging to control whether to use colors in logs or not (on by default) - -* Added support for timestamp with time zone in PostgreSQL #560 [Scott Barron] - -* Added MultiparameterAssignmentErrors and AttributeAssignmentError exceptions #777 [demetrius]. Documentation: - - * +MultiparameterAssignmentErrors+ -- collection of errors that occurred during a mass assignment using the - +attributes=+ method. The +errors+ property of this exception contains an array of +AttributeAssignmentError+ - objects that should be inspected to determine which attributes triggered the errors. - * +AttributeAssignmentError+ -- an error occurred while doing a mass assignment through the +attributes=+ method. - You can inspect the +attribute+ property of the exception object to determine which attribute triggered the error. - -* Fixed that postgresql adapter would fails when reading bytea fields with null value #771 [rodrigo k] - -* Added transactional fixtures that uses rollback to undo changes to fixtures instead of DELETE/INSERT -- it's much faster. See documentation under Fixtures #760 [Jeremy Kemper] - -* Added destruction of dependent objects in has_one associations when a new assignment happens #742 [mindel]. Example: - - class Account < ActiveRecord::Base - has_one :credit_card, :dependent => true - end - class CreditCard < ActiveRecord::Base - belongs_to :account - end - - account.credit_card # => returns existing credit card, lets say id = 12 - account.credit_card = CreditCard.create("number" => "123") - account.save # => CC with id = 12 is destroyed - - -* Added validates_numericality_of #716 [Sebastian Kanthak/Chris McGrath]. Docuemntation: - - Validates whether the value of the specified attribute is numeric by trying to convert it to - a float with Kernel.Float (if integer is false) or applying it to the regular expression - /^[\+\-]?\d+$/ (if integer is set to true). - - class Person < ActiveRecord::Base - validates_numericality_of :value, :on => :create - end - - Configuration options: - * message - A custom error message (default is: "is not a number") - * on Specifies when this validation is active (default is :save, other options :create, :update) - * only_integer Specifies whether the value has to be an integer, e.g. an integral value (default is false) - - -* Fixed that HasManyAssociation#count was using :finder_sql rather than :counter_sql if it was available #445 [Scott Barron] - -* Added better defaults for composed_of, so statements like composed_of :time_zone, :mapping => %w( time_zone time_zone ) can be written without the mapping part (it's now assumed) - -* Added MacroReflection#macro which will return a symbol describing the macro used (like :composed_of or :has_many) #718, #248 [james@slashetc.com] - - -*1.7.0* (24th February, 2005) - -* Changed the auto-timestamping feature to use ActiveRecord::Base.default_timezone instead of entertaining the parallel ActiveRecord::Base.timestamps_gmt method. The latter is now deprecated and will throw a warning on use (but still work) #710 [Jamis Buck] - -* Added a OCI8-based Oracle adapter that has been verified to work with Oracle 8 and 9 #629 [Graham Jenkins]. Usage notes: - - 1. Key generation uses a sequence "rails_sequence" for all tables. (I couldn't find a simple - and safe way of passing table-specific sequence information to the adapter.) - 2. Oracle uses DATE or TIMESTAMP datatypes for both dates and times. Consequently I have had to - resort to some hacks to get data converted to Date or Time in Ruby. - If the column_name ends in _at (like created_at, updated_at) it's created as a Ruby Time. Else if the - hours/minutes/seconds are 0, I make it a Ruby Date. Else it's a Ruby Time. - This is nasty - but if you use Duck Typing you'll probably not care very much. - In 9i it's tempting to map DATE to Date and TIMESTAMP to Time but I don't think that is - valid - too many databases use DATE for both. - Timezones and sub-second precision on timestamps are not supported. - 3. Default values that are functions (such as "SYSDATE") are not supported. This is a - restriction of the way active record supports default values. - 4. Referential integrity constraints are not fully supported. Under at least - some circumstances, active record appears to delete parent and child records out of - sequence and out of transaction scope. (Or this may just be a problem of test setup.) - - The OCI8 driver can be retrieved from http://rubyforge.org/projects/ruby-oci8/ - -* Added option :schema_order to the PostgreSQL adapter to support the use of multiple schemas per database #697 [YuriSchimke] - -* Optimized the SQL used to generate has_and_belongs_to_many queries by listing the join table first #693 [yerejm] - -* Fixed that when using validation macros with a custom message, if you happened to use single quotes in the message string you would get a parsing error #657 [tonka] - -* Fixed that Active Record would throw Broken Pipe errors with FCGI when the MySQL connection timed out instead of reconnecting #428 [Nicholas Seckar] - -* Added options to specify an SSL connection for MySQL. Define the following attributes in the connection config (config/database.yml in Rails) to use it: sslkey, sslcert, sslca, sslcapath, sslcipher. To use SSL with no client certs, just set :sslca = '/dev/null'. http://dev.mysql.com/doc/mysql/en/secure-connections.html #604 [daniel@nightrunner.com] - -* Added automatic dropping/creating of test tables for running the unit tests on all databases #587 [adelle@bullet.net.au] - -* Fixed that find_by_* would fail when column names had numbers #670 [demetrius] - -* Fixed the SQL Server adapter on a bunch of issues #667 [DeLynn] - - 1. Created a new columns method that is much cleaner. - 2. Corrected a problem with the select and select_all methods - that didn't account for the LIMIT clause being passed into raw SQL statements. - 3. Implemented the string_to_time method in order to create proper instances of the time class. - 4. Added logic to the simplified_type method that allows the database to specify the scale of float data. - 5. Adjusted the quote_column_name to account for the fact that MS SQL is bothered by a forward slash in the data string. - -* Fixed that the dynamic finder like find_all_by_something_boolean(false) didn't work #649 [lmarlow] - -* Added validates_each that validates each specified attribute against a block #610 [Jeremy Kemper]. Example: - - class Person < ActiveRecord::Base - validates_each :first_name, :last_name do |record, attr| - record.errors.add attr, 'starts with z.' if attr[0] == ?z - end - end - -* Added :allow_nil as an explicit option for validates_length_of, so unless that's set to true having the attribute as nil will also return an error if a range is specified as :within #610 [Jeremy Kemper] - -* Added that validates_* now accept blocks to perform validations #618 [Tim Bates]. Example: - - class Person < ActiveRecord::Base - validate { |person| person.errors.add("title", "will never be valid") if SHOULD_NEVER_BE_VALID } - end - -* Addded validation for validate all the associated objects before declaring failure with validates_associated #618 [Tim Bates] - -* Added keyword-style approach to defining the custom relational bindings #545 [Jamis Buck]. Example: - - class Project < ActiveRecord::Base - primary_key "sysid" - table_name "XYZ_PROJECT" - inheritance_column { original_inheritance_column + "_id" } - end - -* Fixed Base#clone for use with PostgreSQL #565 [hanson@surgery.wisc.edu] - - -*1.6.0* (January 25th, 2005) - -* Added that has_many association build and create methods can take arrays of record data like Base#create and Base#build to build/create multiple records at once. - -* Added that Base#delete and Base#destroy both can take an array of ids to delete/destroy #336 - -* Added the option of supplying an array of attributes to Base#create, so that multiple records can be created at once. - -* Added the option of supplying an array of ids and attributes to Base#update, so that multiple records can be updated at once (inspired by #526/Duane Johnson). Example - - people = { 1 => { "first_name" => "David" }, 2 => { "first_name" => "Jeremy"} } - Person.update(people.keys, people.values) - -* Added ActiveRecord::Base.timestamps_gmt that can be set to true to make the automated timestamping use GMT instead of local time #520 [Scott Baron] - -* Added that update_all calls sanitize_sql on its updates argument, so stuff like MyRecord.update_all(['time = ?', Time.now]) works #519 [notahat] - -* Fixed that the dynamic finders didn't treat nil as a "IS NULL" but rather "= NULL" case #515 [Demetrius] - -* Added bind-named arrays for interpolating a group of ids or strings in conditions #528 [Jeremy Kemper] - -* Added that has_and_belongs_to_many associations with additional attributes also can be created between unsaved objects and only committed to the database when Base#save is called on the associator #524 [Eric Anderson] - -* Fixed that records fetched with piggy-back attributes or through rich has_and_belongs_to_many associations couldn't be saved due to the extra attributes not part of the table #522 [Eric Anderson] - -* Added mass-assignment protection for the inheritance column -- regardless of a custom column is used or not - -* Fixed that association proxies would fail === tests like PremiumSubscription === @account.subscription - -* Fixed that column aliases didn't work as expected with the new MySql411 driver #507 [Demetrius] - -* Fixed that find_all would produce invalid sql when called sequentialy #490 [Scott Baron] - - -*1.5.1* (January 18th, 2005) - -* Fixed that the belongs_to and has_one proxy would fail a test like 'if project.manager' -- this unfortunately also means that you can't call methods like project.manager.build unless there already is a manager on the project #492 [Tim Bates] - -* Fixed that the Ruby/MySQL adapter wouldn't connect if the password was empty #503 [Pelle] - - -*1.5.0* (January 17th, 2005) - -* Fixed that unit tests for MySQL are now run as the "rails" user instead of root #455 [Eric Hodel] - -* Added validates_associated that enables validation of objects in an unsaved association #398 [Tim Bates]. Example: - - class Book < ActiveRecord::Base - has_many :pages - belongs_to :library - - validates_associated :pages, :library - end - -* Added support for associating unsaved objects #402 [Tim Bates]. Rules that govern this addition: - - == Unsaved objects and associations - - You can manipulate objects and associations before they are saved to the database, but there is some special behaviour you should be - aware of, mostly involving the saving of associated objects. - - === One-to-one associations - - * Assigning an object to a has_one association automatically saves that object, and the object being replaced (if there is one), in - order to update their primary keys - except if the parent object is unsaved (new_record? == true). - * If either of these saves fail (due to one of the objects being invalid) the assignment statement returns false and the assignment - is cancelled. - * If you wish to assign an object to a has_one association without saving it, use the #association.build method (documented below). - * Assigning an object to a belongs_to association does not save the object, since the foreign key field belongs on the parent. It does - not save the parent either. - - === Collections - - * Adding an object to a collection (has_many or has_and_belongs_to_many) automatically saves that object, except if the parent object - (the owner of the collection) is not yet stored in the database. - * If saving any of the objects being added to a collection (via #push or similar) fails, then #push returns false. - * You can add an object to a collection without automatically saving it by using the #collection.build method (documented below). - * All unsaved (new_record? == true) members of the collection are automatically saved when the parent is saved. - -* Added replace to associations, so you can do project.manager.replace(new_manager) or project.milestones.replace(new_milestones) #402 [Tim Bates] - -* Added build and create methods to has_one and belongs_to associations, so you can now do project.manager.build(attributes) #402 [Tim Bates] - -* Added that if a before_* callback returns false, all the later callbacks and the associated action are cancelled. If an after_* callback returns false, all the later callbacks are cancelled. Callbacks are generally run in the order they are defined, with the exception of callbacks defined as methods on the model, which are called last. #402 [Tim Bates] - -* Fixed that Base#== wouldn't work for multiple references to the same unsaved object #402 [Tim Bates] - -* Fixed binary support for PostgreSQL #444 [alex@byzantine.no] - -* Added a differenciation between AssociationCollection#size and -length. Now AssociationCollection#size returns the size of the - collection by executing a SELECT COUNT(*) query if the collection hasn't been loaded and calling collection.size if it has. If - it's more likely than not that the collection does have a size larger than zero and you need to fetch that collection afterwards, - it'll take one less SELECT query if you use length. - -* Added Base#attributes that returns a hash of all the attributes with their names as keys and clones of their objects as values #433 [atyp.de] - -* Fixed that foreign keys named the same as the association would cause stack overflow #437 [Eric Anderson] - -* Fixed default scope of acts_as_list from "1" to "1 = 1", so it'll work in PostgreSQL (among other places) #427 [Alexey] - -* Added Base#reload that reloads the attributes of an object from the database #422 [Andreas Schwarz] - -* Added SQLite3 compatibility through the sqlite3-ruby adapter by Jamis Buck #381 [Jeremy Kemper] - -* Added support for the new protocol spoken by MySQL 4.1.1+ servers for the Ruby/MySQL adapter that ships with Rails #440 [Matt Mower] - -* Added that Observers can use the observes class method instead of overwriting self.observed_class(). - - Before: - class ListSweeper < ActiveRecord::Base - def self.observed_class() [ List, Item ] - end - - After: - class ListSweeper < ActiveRecord::Base - observes List, Item - end - -* Fixed that conditions in has_many and has_and_belongs_to_many should be interpolated just like the finder_sql is - -* Fixed Base#update_attribute to be indifferent to whether a string or symbol is used to describe the name - -* Added Base#toggle(attribute) and Base#toggle!(attribute) that makes it easier to flip a switch or flag. - - Before: topic.update_attribute(:approved, !approved?) - After : topic.toggle!(:approved) - -* Added Base#increment!(attribute) and Base#decrement!(attribute) that also saves the records. Example: - - page.views # => 1 - page.increment!(:views) # executes an UPDATE statement - page.views # => 2 - - page.increment(:views).increment!(:views) - page.views # => 4 - -* Added Base#increment(attribute) and Base#decrement(attribute) that encapsulates the += 1 and -= 1 patterns. - - -*1.4.0* (January 4th, 2005) - -* Added automated optimistic locking if the field lock_version is present. Each update to the - record increments the lock_version column and the locking facilities ensure that records instantiated twice - will let the last one saved raise a StaleObjectError if the first was also updated. Example: - - p1 = Person.find(1) - p2 = Person.find(1) - - p1.first_name = "Michael" - p1.save - - p2.first_name = "should fail" - p2.save # Raises a ActiveRecord::StaleObjectError - - You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging, - or otherwise apply the business logic needed to resolve the conflict. - - #384 [Michael Koziarski] - -* Added dynamic attribute-based finders as a cleaner way of getting objects by simple queries without turning to SQL. - They work by appending the name of an attribute to find_by_, so you get finders like Person.find_by_user_name, - Payment.find_by_transaction_id. So instead of writing Person.find_first(["user_name = ?", user_name]), you just do - Person.find_by_user_name(user_name). - - It's also possible to use multiple attributes in the same find by separating them with "_and_", so you get finders like - Person.find_by_user_name_and_password or even Payment.find_by_purchaser_and_state_and_country. So instead of writing - Person.find_first(["user_name = ? AND password = ?", user_name, password]), you just do - Person.find_by_user_name_and_password(user_name, password). - - While primarily a construct for easier find_firsts, it can also be used as a construct for find_all by using calls like - Payment.find_all_by_amount(50) that is turned into Payment.find_all(["amount = ?", 50]). This is something not as equally useful, - though, as it's not possible to specify the order in which the objects are returned. - -* Added block-style for callbacks #332 [Jeremy Kemper]. - - Before: - before_destroy(Proc.new{ |record| Person.destroy_all "firm_id = #{record.id}" }) - - After: - before_destroy { |record| Person.destroy_all "firm_id = #{record.id}" } - -* Added :counter_cache option to acts_as_tree that works just like the one you can define on belongs_to #371 [Josh Peek] - -* Added Base.default_timezone accessor that determines whether to use Time.local (using :local) or Time.utc (using :utc) when pulling dates - and times from the database. This is set to :local by default. - -* Added the possibility for adapters to overwrite add_limit! to implement a different limiting scheme than "LIMIT X" used by MySQL, PostgreSQL, and SQLite. - -* Added the possibility of having objects with acts_as_list created before their scope is available or... - -* Added a db2 adapter that only depends on the Ruby/DB2 bindings (http://raa.ruby-lang.org/project/ruby-db2/) #386 [Maik Schmidt] - -* Added the final touches to the Microsoft SQL Server adapter by Joey Gibson that makes it suitable for actual use #394 [DeLynn Barry] - -* Added that Base#find takes an optional options hash, including :conditions. Base#find_on_conditions deprecated in favor of #find with :conditions #407 [Jeremy Kemper] - -* Added HasManyAssociation#count that works like Base#count #413 [intinig] - -* Fixed handling of binary content in blobs and similar fields for Ruby/MySQL and SQLite #409 [xal] - -* Fixed a bug in the Ruby/MySQL that caused binary content to be escaped badly and come back mangled #405 [Tobias Lütke] - -* Fixed that the const_missing autoload assumes the requested constant is set by require_association and calls const_get to retrieve it. - If require_association did not set the constant then const_get will call const_missing, resulting in an infinite loop #380 [Jeremy Kemper] - -* Fixed broken transactions that were actually only running object-level and not db level transactions [andreas] - -* Fixed that validates_uniqueness_of used 'id' instead of defined primary key #406 - -* Fixed that the overwritten respond_to? method didn't take two parameters like the original #391 - -* Fixed quoting in validates_format_of that would allow some rules to pass regardless of input #390 [Dmitry V. Sabanin] - - -*1.3.0* (December 23, 2004) - -* Added a require_association hook on const_missing that makes it possible to use any model class without requiring it first. This makes STI look like: - - before: - require_association 'person' - class Employee < Person - end - - after: - class Employee < Person - end - - This also reduces the usefulness of Controller.model in Action Pack to currently only being for documentation purposes. - -* Added that Base.update_all and Base.delete_all return an integer of the number of affected rows #341 - -* Added scope option to validation_uniqueness #349 [Kent Sibilev] - -* Added respondence to *_before_type_cast for all attributes to return their string-state before they were type casted by the column type. - This is helpful for getting "100,000" back on a integer-based validation where the value would normally be "100". - -* Added allow_nil options to validates_inclusion_of so that validation is only triggered if the attribute is not nil [what-a-day] - -* Added work-around for PostgreSQL and the problem of getting fixtures to be created from id 1 on each test case. - This only works for auto-incrementing primary keys called "id" for now #359 [Scott Baron] - -* Added Base#clear_association_cache to empty all the cached associations #347 [Tobias Lütke] - -* Added more informative exceptions in establish_connection #356 [Jeremy Kemper] - -* Added Base#update_attributes that'll accept a hash of attributes and save the record (returning true if it passed validation, false otherwise). - - Before: - person.attributes = @params["person"] - person.save - - Now: - person.update_attributes(@params["person"]) - -* Added Base.destroy and Base.delete to remove records without holding a reference to them first. - -* Added that query benchmarking will only happen if its going to be logged anyway #344 - -* Added higher_item and lower_item as public methods for acts_as_list #342 [Tobias Lütke] - -* Fixed that options[:counter_sql] was overwritten with interpolated sql rather than original sql #355 [Jeremy Kemper] - -* Fixed that overriding an attribute's accessor would be disregarded by add_on_empty and add_on_boundary_breaking because they simply used - the attributes[] hash instead of checking for @base.respond_to?(attr.to_s). [Marten] - -* Fixed that Base.table_name would expect a parameter when used in has_and_belongs_to_many joins [Anna Lissa Cruz] - -* Fixed that nested transactions now work by letting the outer most transaction have the responsibilty of starting and rolling back the transaction. - If any of the inner transactions swallow the exception raised, though, the transaction will not be rolled back. So always let the transaction - bubble up even when you've dealt with local issues. Closes #231 and #340. - -* Fixed validates_{confirmation,acceptance}_of to only happen when the virtual attributes are not nil #348 [dpiddy@gmail.com] - -* Changed the interface on AbstractAdapter to require that adapters return the number of affected rows on delete and update operations. - -* Fixed the automated timestamping feature when running under Rails' development environment that resets the inheritable attributes on each request. - - - -*1.2.0* - -* Added Base.validates_inclusion_of that validates whether the value of the specified attribute is available in a particular enumerable - object. [what-a-day] - - class Person < ActiveRecord::Base - validates_inclusion_of :gender, :in=>%w( m f ), :message=>"woah! what are you then!??!!" - validates_inclusion_of :age, :in=>0..99 - end - -* Added acts_as_list that can decorates an existing class with methods like move_higher/lower, move_to_top/bottom. [Tobias Lütke] Example: - - class TodoItem < ActiveRecord::Base - acts_as_list :scope => :todo_list_id - belongs_to :todo_list - end - -* Added acts_as_tree that can decorates an existing class with a many to many relationship with itself. Perfect for categories in - categories and the likes. [Tobias Lütke] - -* Added that Active Records will automatically record creation and/or update timestamps of database objects if fields of the names - created_at/created_on or updated_at/updated_on are present. [Tobias Lütke] - -* Added Base.default_error_messages as a hash of all the error messages used in the validates_*_of so they can be changed in one place [Tobias Lütke] - -* Added automatic transaction block around AssociationCollection.<<, AssociationCollection.delete, and AssociationCollection.destroy_all - -* Fixed that Base#find will return an array if given an array -- regardless of the number of elements #270 [Marten] - -* Fixed that has_and_belongs_to_many would generate bad sql when naming conventions differed from using vanilla "id" everywhere [RedTerror] - -* Added a better exception for when a type column is used in a table without the intention of triggering single-table inheritance. Example: - - ActiveRecord::SubclassNotFound: The single-table inheritance mechanism failed to locate the subclass: 'bad_class!'. - This error is raised because the column 'type' is reserved for storing the class in case of inheritance. - Please rename this column if you didn't intend it to be used for storing the inheritance class or - overwrite Company.inheritance_column to use another column for that information. - -* Added that single-table inheritance will only kick in if the inheritance_column (by default "type") is present. Otherwise, inheritance won't - have any magic side effects. - -* Added the possibility of marking fields as being in error without adding a message (using nil) to it that'll get displayed wth full_messages #208 [mjobin] - -* Fixed Base.errors to be indifferent as to whether strings or symbols are used. Examples: - - Before: - errors.add(:name, "must be shorter") if name.size > 10 - errors.on(:name) # => "must be shorter" - errors.on("name") # => nil - - After: - errors.add(:name, "must be shorter") if name.size > 10 - errors.on(:name) # => "must be shorter" - errors.on("name") # => "must be shorter" - -* Added Base.validates_format_of that Validates whether the value of the specified attribute is of the correct form by matching - it against the regular expression provided. [Marcel Molina Jr.] - - class Person < ActiveRecord::Base - validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/, :on => :create - end - -* Added Base.validates_length_of that delegates to add_on_boundary_breaking #312 [Tobias Lütke]. Example: - - Validates that the specified attribute matches the length restrictions supplied in either: - - - configuration[:minimum] - - configuration[:maximum] - - configuration[:is] - - configuration[:within] (aka. configuration[:in]) - - Only one option can be used at a time. - - class Person < ActiveRecord::Base - validates_length_of :first_name, :maximum=>30 - validates_length_of :last_name, :maximum=>30, :message=>"less than %d if you don't mind" - validates_length_of :user_name, :within => 6..20, :too_long => "pick a shorter name", :too_short => "pick a longer name" - validates_length_of :fav_bra_size, :minimum=>1, :too_short=>"please enter at least %d character" - validates_length_of :smurf_leader, :is=>4, :message=>"papa is spelled with %d characters... don't play me." - end - -* Added Base.validate_presence as an alternative to implementing validate and doing errors.add_on_empty yourself. - -* Added Base.validates_uniqueness_of that alidates whether the value of the specified attributes are unique across the system. - Useful for making sure that only one user can be named "davidhh". - - class Person < ActiveRecord::Base - validates_uniqueness_of :user_name - end - - When the record is created, a check is performed to make sure that no record exist in the database with the given value for the specified - attribute (that maps to a column). When the record is updated, the same check is made but disregarding the record itself. - - -* Added Base.validates_confirmation_of that encapsulates the pattern of wanting to validate a password or email address field with a confirmation. Example: - - Model: - class Person < ActiveRecord::Base - validates_confirmation_of :password - end - - View: - <%= password_field "person", "password" %> - <%= password_field "person", "password_confirmation" %> - - The person has to already have a password attribute (a column in the people table), but the password_confirmation is virtual. - It exists only as an in-memory variable for validating the password. This check is performed both on create and update. - - -* Added Base.validates_acceptance_of that encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement). Example: - - class Person < ActiveRecord::Base - validates_acceptance_of :terms_of_service - end - - The terms_of_service attribute is entirely virtual. No database column is needed. This check is performed both on create and update. - - NOTE: The agreement is considered valid if it's set to the string "1". This makes it easy to relate it to an HTML checkbox. - - -* Added validation macros to make the stackable just like the life cycle callbacks. Examples: - - class Person < ActiveRecord::Base - validate { |record| record.errors.add("name", "too short") unless name.size > 10 } - validate { |record| record.errors.add("name", "too long") unless name.size < 20 } - validate_on_create :validate_password - - private - def validate_password - errors.add("password", "too short") unless password.size > 6 - end - end - -* Added the option for sanitizing find_by_sql and the offset parts in regular finds [Sam Stephenson]. Examples: - - Project.find_all ["category = ?", category_name], "created ASC", ["? OFFSET ?", 15, 20] - Post.find_by_sql ["SELECT * FROM posts WHERE author = ? AND created > ?", author_id, start_date] - -* Fixed value quoting in all generated SQL statements, so that integers are not surrounded in quotes and that all sanitation are happening - through the database's own quoting routine. This should hopefully make it lots easier for new adapters that doesn't accept '1' for integer - columns. - -* Fixed has_and_belongs_to_many guessing of foreign key so that keys are generated correctly for models like SomeVerySpecialClient - [Florian Weber] - -* Added counter_sql option for has_many associations [Jeremy Kemper]. Documentation: - - :counter_sql - specify a complete SQL statement to fetch the size of the association. If +:finder_sql+ is - specified but +:counter_sql+, +:counter_sql+ will be generated by replacing SELECT ... FROM with SELECT COUNT(*) FROM. - -* Fixed that methods wrapped in callbacks still return their original result #260 [Jeremy Kemper] - -* Fixed the Inflector to handle the movie/movies pair correctly #261 [Scott Baron] - -* Added named bind-style variable interpolation #281 [Michael Koziarski]. Example: - - Person.find(["id = :id and first_name = :first_name", { :id => 5, :first_name = "bob' or 1=1" }]) - -* Added bind-style variable interpolation for the condition arrays that uses the adapter's quote method [Michael Koziarski] - - Before: - find_first([ "user_name = '%s' AND password = '%s'", user_name, password ])] - find_first([ "firm_id = %s", firm_id ])] # unsafe! - - After: - find_first([ "user_name = ? AND password = ?", user_name, password ])] - find_first([ "firm_id = ?", firm_id ])] - -* Added CSV format for fixtures #272 [what-a-day]. (See the new and expanded documentation on fixtures for more information) - -* Fixed fixtures using primary key fields called something else than "id" [dave] - -* Added proper handling of time fields that are turned into Time objects with the dummy date of 2000/1/1 [HariSeldon] - -* Added reverse order of deleting fixtures, so referential keys can be maintained #247 [Tim Bates] - -* Added relative path search for sqlite dbfiles in database.yml (if RAILS_ROOT is defined) #233 [Jeremy Kemper] - -* Added option to establish_connection where you'll be able to leave out the parameter to have it use the RAILS_ENV environment variable - -* Fixed problems with primary keys and postgresql sequences (#230) [Tim Bates] - -* Added reloading for associations under cached environments like FastCGI and mod_ruby. This makes it possible to use those environments for development. - This is turned on by default, but can be turned off with ActiveRecord::Base.reload_dependencies = false in production environments. - - NOTE: This will only have an effect if you let the associations manage the requiring of model classes. All libraries loaded through - require will be "forever" cached. You can, however, use ActiveRecord::Base.load_or_require("library") to get this behavior outside of the - auto-loading associations. - -* Added ERB capabilities to the fixture files for dynamic fixture generation. You don't need to do anything, just include ERB blocks like: - - david: - id: 1 - name: David - - jamis: - id: 2 - name: Jamis - - <% for digit in 3..10 %> - dev_<%= digit %>: - id: <%= digit %> - name: fixture_<%= digit %> - <% end %> - -* Changed the yaml fixture searcher to look in the root of the fixtures directory, so when you before could have something like: - - fixtures/developers/fixtures.yaml - fixtures/accounts/fixtures.yaml - - ...you now need to do: - - fixtures/developers.yaml - fixtures/accounts.yaml - -* Changed the fixture format from: - - name: david - data: - id: 1 - name: David Heinemeier Hansson - birthday: 1979-10-15 - profession: Systems development - --- - name: steve - data: - id: 2 - name: Steve Ross Kellock - birthday: 1974-09-27 - profession: guy with keyboard - - ...to: - - david: - id: 1 - name: David Heinemeier Hansson - birthday: 1979-10-15 - profession: Systems development - - steve: - id: 2 - name: Steve Ross Kellock - birthday: 1974-09-27 - profession: guy with keyboard - - The change is NOT backwards compatible. Fixtures written in the old YAML style needs to be rewritten! - -* All associations will now attempt to require the classes that they associate to. Relieving the need for most explicit 'require' statements. - - -*1.1.0* (34) - -* Added automatic fixture setup and instance variable availability. Fixtures can also be automatically - instantiated in instance variables relating to their names using the following style: - - class FixturesTest < Test::Unit::TestCase - fixtures :developers # you can add more with comma separation - - def test_developers - assert_equal 3, @developers.size # the container for all the fixtures is automatically set - assert_kind_of Developer, @david # works like @developers["david"].find - assert_equal "David Heinemeier Hansson", @david.name - end - end - -* Added HasAndBelongsToManyAssociation#push_with_attributes(object, join_attributes) that can create associations in the join table with additional - attributes. This is really useful when you have information that's only relevant to the join itself, such as a "added_on" column for an association - between post and category. The added attributes will automatically be injected into objects retrieved through the association similar to the piggy-back - approach: - - post.categories.push_with_attributes(category, :added_on => Date.today) - post.categories.first.added_on # => Date.today - - NOTE: The categories table doesn't have a added_on column, it's the categories_post join table that does! - -* Fixed that :exclusively_dependent and :dependent can't be activated at the same time on has_many associations [Jeremy Kemper] - -* Fixed that database passwords couldn't be all numeric [Jeremy Kemper] - -* Fixed that calling id would create the instance variable for new_records preventing them from being saved correctly [Jeremy Kemper] - -* Added sanitization feature to HasManyAssociation#find_all so it works just like Base.find_all [Sam Stephenson/Jeremy Kemper] - -* Added that you can pass overlapping ids to find without getting duplicated records back [Jeremy Kemper] - -* Added that Base.benchmark returns the result of the block [Jeremy Kemper] - -* Fixed problem with unit tests on Windows with SQLite [paterno] - -* Fixed that quotes would break regular non-yaml fixtures [Dmitry Sabanin/daft] - -* Fixed fixtures on windows with line endings cause problems under unix / mac [Tobias Lütke] - -* Added HasAndBelongsToManyAssociation#find(id) that'll search inside the collection and find the object or record with that id - -* Added :conditions option to has_and_belongs_to_many that works just like the one on all the other associations - -* Added AssociationCollection#clear to remove all associations from has_many and has_and_belongs_to_many associations without destroying the records [geech] - -* Added type-checking and remove in 1-instead-of-N sql statements to AssociationCollection#delete [geech] - -* Added a return of self to AssociationCollection#<< so appending can be chained, like project << Milestone.create << Milestone.create [geech] - -* Added Base#hash and Base#eql? which means that all of the equality using features of array and other containers now works: - - [ Person.find(1), Person.find(2), Person.find(3) ] & [ Person.find(1), Person.find(4) ] # => [ Person.find(1) ] - -* Added :uniq as an option to has_and_belongs_to_many which will automatically ensure that AssociateCollection#uniq is called - before pulling records out of the association. This is especially useful for three-way (and above) has_and_belongs_to_many associations. - -* Added AssociateCollection#uniq which is especially useful for has_and_belongs_to_many associations that can include duplicates, - which is common on associations that also use metadata. Usage: post.categories.uniq - -* Fixed respond_to? to use a subclass specific hash instead of an Active Record-wide one - -* Fixed has_and_belongs_to_many to treat associations between classes in modules properly [Florian Weber] - -* Added a NoMethod exception to be raised when query and writer methods are called for attributes that doesn't exist [geech] - -* Added a more robust version of Fixtures that throws meaningful errors when on formatting issues [geech] - -* Added Base#transaction as a compliment to Base.transaction for prettier use in instance methods [geech] - -* Improved the speed of respond_to? by placing the dynamic methods lookup table in a hash [geech] - -* Added that any additional fields added to the join table in a has_and_belongs_to_many association - will be placed as attributes when pulling records out through has_and_belongs_to_many associations. - This is helpful when have information about the association itself that you want available on retrival. - -* Added better loading exception catching and RubyGems retries to the database adapters [alexeyv] - -* Fixed bug with per-model transactions [daniel] - -* Fixed Base#transaction so that it returns the result of the last expression in the transaction block [alexeyv] - -* Added Fixture#find to find the record corresponding to the fixture id. The record - class name is guessed by using Inflector#classify (also new) on the fixture directory name. - - Before: Document.find(@documents["first"]["id"]) - After : @documents["first"].find - -* Fixed that the table name part of column names ("TABLE.COLUMN") wasn't removed properly [Andreas Schwarz] - -* Fixed a bug with Base#size when a finder_sql was used that didn't capitalize SELECT and FROM [geech] - -* Fixed quoting problems on SQLite by adding quote_string to the AbstractAdapter that can be overwritten by the concrete - adapters for a call to the dbm. [Andreas Schwarz] - -* Removed RubyGems backup strategy for requiring SQLite-adapter -- if people want to use gems, they're already doing it with AR. - - -*1.0.0 (35)* - -* Added OO-style associations methods [Florian Weber]. Examples: - - Project#milestones_count => Project#milestones.size - Project#build_to_milestones => Project#milestones.build - Project#create_for_milestones => Project#milestones.create - Project#find_in_milestones => Project#milestones.find - Project#find_all_in_milestones => Project#milestones.find_all - -* Added serialize as a new class method to control when text attributes should be YAMLized or not. This means that automated - serialization of hashes, arrays, and so on WILL NO LONGER HAPPEN (#10). You need to do something like this: - - class User < ActiveRecord::Base - serialize :settings - end - - This will assume that settings is a text column and will now YAMLize any object put in that attribute. You can also specify - an optional :class_name option that'll raise an exception if a serialized object is retrieved as a descendant of a class not in - the hierarchy. Example: - - class User < ActiveRecord::Base - serialize :settings, :class_name => "Hash" - end - - user = User.create("settings" => %w( one two three )) - User.find(user.id).settings # => raises SerializationTypeMismatch - -* Added the option to connect to a different database for one model at a time. Just call establish_connection on the class - you want to have connected to another database than Base. This will automatically also connect decendents of that class - to the different database [Renald Buter]. - -* Added transactional protection for Base#save. Validations can now check for values knowing that it happens in a transaction and callbacks - can raise exceptions knowing that the save will be rolled back. [Suggested by Alexey Verkhovsky] - -* Added column name quoting so reserved words, such as "references", can be used as column names [Ryan Platte] - -* Added the possibility to chain the return of what happened inside a logged block [geech]: - - This now works: - log { ... }.map { ... } - - Instead of doing: - result = [] - log { result = ... } - result.map { ... } - -* Added "socket" option for the MySQL adapter, so you can change it to something else than "/tmp/mysql.sock" [Anna Lissa Cruz] - -* Added respond_to? answers for all the attribute methods. So if Person has a name attribute retrieved from the table schema, - person.respond_to? "name" will return true. - -* Added Base.benchmark which can be used to aggregate logging and benchmark, so you can measure and represent multiple statements in a single block. - Usage (hides all the SQL calls for the individual actions and calculates total runtime for them all): - - Project.benchmark("Creating project") do - project = Project.create("name" => "stuff") - project.create_manager("name" => "David") - project.milestones << Milestone.find_all - end - -* Added logging of invalid SQL statements [Daniel Von Fange] - -* Added alias Errors#[] for Errors#on, so you can now say person.errors["name"] to retrieve the errors for name [Andreas Schwarz] - -* Added RubyGems require attempt if sqlite-ruby is not available through regular methods. - -* Added compatibility with 2.x series of sqlite-ruby drivers. [Jamis Buck] - -* Added type safety for association assignments, so a ActiveRecord::AssociationTypeMismatch will be raised if you attempt to - assign an object that's not of the associated class. This cures the problem with nil giving id = 4 and fixnums giving id = 1 on - mistaken association assignments. [Reported by Andreas Schwarz] - -* Added the option to keep many fixtures in one single YAML document [what-a-day] - -* Added the class method "inheritance_column" that can be overwritten to return the name of an alternative column than "type" for storing - the type for inheritance hierarchies. [Dave Steinberg] - -* Added [] and []= as an alternative way to access attributes when the regular methods have been overwritten [Dave Steinberg] - -* Added the option to observer more than one class at the time by specifying observed_class as an array - -* Added auto-id propagation support for tables with arbitrary primary keys that have autogenerated sequences associated with them - on PostgreSQL. [Dave Steinberg] - -* Changed that integer and floats set to "" through attributes= remain as NULL. This was especially a problem for scaffolding and postgresql. (#49) - -* Changed the MySQL Adapter to rely on MySQL for its defaults for socket, host, and port [Andreas Schwarz] - -* Changed ActionControllerError to decent from StandardError instead of Exception. It can now be caught by a generic rescue. - -* Changed class inheritable attributes to not use eval [Caio Chassot] - -* Changed Errors#add to now use "invalid" as the default message instead of true, which means full_messages work with those [Marcel Molina Jr.] - -* Fixed spelling on Base#add_on_boundry_breaking to Base#add_on_boundary_breaking (old naming still works) [Marcel Molina Jr.] - -* Fixed that entries in the has_and_belongs_to_many join table didn't get removed when an associated object was destroyed. - -* Fixed unnecessary calls to SET AUTOCOMMIT=0/1 for MySQL adapter [Andreas Schwarz] - -* Fixed PostgreSQL defaults are now handled gracefully [Dave Steinberg] - -* Fixed increment/decrement_counter are now atomic updates [Andreas Schwarz] - -* Fixed the problems the Inflector had turning Attachment into attuchments and Cases into Casis [radsaq/Florian Gross] - -* Fixed that cloned records would point attribute references on the parent object [Andreas Schwarz] - -* Fixed SQL for type call on inheritance hierarchies [Caio Chassot] - -* Fixed bug with typed inheritance [Florian Weber] - -* Fixed a bug where has_many collection_count wouldn't use the conditions specified for that association - - -*0.9.5* - -* Expanded the table_name guessing rules immensely [Florian Green]. Documentation: - - Guesses the table name (in forced lower-case) based on the name of the class in the inheritance hierarchy descending - directly from ActiveRecord. So if the hierarchy looks like: Reply < Message < ActiveRecord, then Message is used - to guess the table name from even when called on Reply. The guessing rules are as follows: - * Class name ends in "x", "ch" or "ss": "es" is appended, so a Search class becomes a searches table. - * Class name ends in "y" preceded by a consonant or "qu": The "y" is replaced with "ies", - so a Category class becomes a categories table. - * Class name ends in "fe": The "fe" is replaced with "ves", so a Wife class becomes a wives table. - * Class name ends in "lf" or "rf": The "f" is replaced with "ves", so a Half class becomes a halves table. - * Class name ends in "person": The "person" is replaced with "people", so a Salesperson class becomes a salespeople table. - * Class name ends in "man": The "man" is replaced with "men", so a Spokesman class becomes a spokesmen table. - * Class name ends in "sis": The "i" is replaced with an "e", so a Basis class becomes a bases table. - * Class name ends in "tum" or "ium": The "um" is replaced with an "a", so a Datum class becomes a data table. - * Class name ends in "child": The "child" is replaced with "children", so a NodeChild class becomes a node_children table. - * Class name ends in an "s": No additional characters are added or removed. - * Class name doesn't end in "s": An "s" is appended, so a Comment class becomes a comments table. - * Class name with word compositions: Compositions are underscored, so CreditCard class becomes a credit_cards table. - Additionally, the class-level table_name_prefix is prepended to the table_name and the table_name_suffix is appended. - So if you have "myapp_" as a prefix, the table name guess for an Account class becomes "myapp_accounts". - - You can also overwrite this class method to allow for unguessable links, such as a Mouse class with a link to a - "mice" table. Example: - - class Mouse < ActiveRecord::Base - def self.table_name() "mice" end - end - - This conversion is now done through an external class called Inflector residing in lib/active_record/support/inflector.rb. - -* Added find_all_in_collection to has_many defined collections. Works like this: - - class Firm < ActiveRecord::Base - has_many :clients - end - - firm.id # => 1 - firm.find_all_in_clients "revenue > 1000" # SELECT * FROM clients WHERE firm_id = 1 AND revenue > 1000 - - [Requested by Dave Thomas] - -* Fixed finders for inheritance hierarchies deeper than one level [Florian Weber] - -* Added add_on_boundry_breaking to errors to accompany add_on_empty as a default validation method. It's used like this: - - class Person < ActiveRecord::Base - protected - def validation - errors.add_on_boundry_breaking "password", 3..20 - end - end - - This will add an error to the tune of "is too short (minimum is 3 characters)" or "is too long (minimum is 20 characters)" if - the password is outside the boundry. The messages can be changed by passing a third and forth parameter as message strings. - -* Implemented a clone method that works properly with AR. It returns a clone of the record that - hasn't been assigned an id yet and is treated as a new record. - -* Allow for domain sockets in PostgreSQL by not assuming localhost when no host is specified [Scott Barron] - -* Fixed that bignums are saved properly instead of attempted to be YAMLized [Andreas Schwartz] - -* Fixed a bug in the GEM where the rdoc options weren't being passed according to spec [Chad Fowler] - -* Fixed a bug with the exclusively_dependent option for has_many - - -*0.9.4* - -* Correctly guesses the primary key when the class is inside a module [Dave Steinberg]. - -* Added [] and []= as alternatives to read_attribute and write_attribute [Dave Steinberg] - -* has_and_belongs_to_many now accepts an :order key to determine in which order the collection is returned [radsaq]. - -* The ids passed to find and find_on_conditions are now automatically sanitized. - -* Added escaping of plings in YAML content. - -* Multi-parameter assigns where all the parameters are empty will now be set to nil instead of a new instance of their class. - -* Proper type within an inheritance hierarchy is now ensured already at object initialization (instead of first at create) - - -*0.9.3* - -* Fixed bug with using a different primary key name together with has_and_belongs_to_many [Investigation by Scott] - -* Added :exclusively_dependent option to the has_many association macro. The doc reads: - - If set to true all the associated object are deleted in one SQL statement without having their - before_destroy callback run. This should only be used on associations that depend solely on - this class and don't need to do any clean-up in before_destroy. The upside is that it's much - faster, especially if there's a counter_cache involved. - -* Added :port key to connection options, so the PostgreSQL and MySQL adapters can connect to a database server - running on another port than the default. - -* Converted the new natural singleton methods that prevented AR objects from being saved by PStore - (and hence be placed in a Rails session) to a module. [Florian Weber] - -* Fixed the use of floats (was broken since 0.9.0+) - -* Fixed PostgreSQL adapter so default values are displayed properly when used in conjunction with - Action Pack scaffolding. - -* Fixed booleans support for PostgreSQL (use real true/false on boolean fields instead of 0/1 on tinyints) [radsaq] - - -*0.9.2* - -* Added static method for instantly updating a record - -* Treat decimal and numeric as Ruby floats [Andreas Schwartz] - -* Treat chars as Ruby strings (fixes problem for Action Pack form helpers too) - -* Removed debugging output accidently left in (which would screw web applications) - - -*0.9.1* - -* Added MIT license - -* Added natural object-style assignment for has_and_belongs_to_many associations. Consider the following model: - - class Event < ActiveRecord::Base - has_one_and_belongs_to_many :sponsors - end - - class Sponsor < ActiveRecord::Base - has_one_and_belongs_to_many :sponsors - end - - Earlier, you'd have to use synthetic methods for creating associations between two objects of the above class: - - roskilde_festival.add_to_sponsors(carlsberg) - roskilde_festival.remove_from_sponsors(carlsberg) - - nike.add_to_events(world_cup) - nike.remove_from_events(world_cup) - - Now you can use regular array-styled methods: - - roskilde_festival.sponsors << carlsberg - roskilde_festival.sponsors.delete(carlsberg) - - nike.events << world_cup - nike.events.delete(world_cup) - -* Added delete method for has_many associations. Using this will nullify an association between the has_many and the belonging - object by setting the foreign key to null. Consider this model: - - class Post < ActiveRecord::Base - has_many :comments - end - - class Comment < ActiveRecord::Base - belongs_to :post - end - - You could do something like: - - funny_comment.has_post? # => true - announcement.comments.delete(funny_comment) - funny_comment.has_post? # => false - - -*0.9.0* - -* Active Record is now thread safe! (So you can use it with Cerise and WEBrick applications) - [Implementation idea by Michael Neumann, debugging assistance by Jamis Buck] - -* Improved performance by roughly 400% on a basic test case of pulling 100 records and querying one attribute. - This brings the tax for using Active Record instead of "riding on the metal" (using MySQL-ruby C-driver directly) down to ~50%. - Done by doing lazy type conversions and caching column information on the class-level. - -* Added callback objects and procs as options for implementing the target for callback macros. - -* Added "counter_cache" option to belongs_to that automates the usage of increment_counter and decrement_counter. Consider: - - class Post < ActiveRecord::Base - has_many :comments - end - - class Comment < ActiveRecord::Base - belongs_to :post - end - - Iterating over 100 posts like this: - - <% for post in @posts %> - <%= post.title %> has <%= post.comments_count %> comments - <% end %> - - Will generate 100 SQL count queries -- one for each call to post.comments_count. If you instead add a "comments_count" int column - to the posts table and rewrite the comments association macro with: - - class Comment < ActiveRecord::Base - belongs_to :post, :counter_cache => true - end - - Those 100 SQL count queries will be reduced to zero. Beware that counter caching is only appropriate for objects that begin life - with the object it's specified to belong with and is destroyed like that as well. Typically objects where you would also specify - :dependent => true. If your objects switch from one belonging to another (like a post that can be move from one category to another), - you'll have to manage the counter yourself. - -* Added natural object-style assignment for has_one and belongs_to associations. Consider the following model: - - class Project < ActiveRecord::Base - has_one :manager - end - - class Manager < ActiveRecord::Base - belongs_to :project - end - - Earlier, assignments would work like following regardless of which way the assignment told the best story: - - active_record.manager_id = david.id - - Now you can do it either from the belonging side: - - david.project = active_record - - ...or from the having side: - - active_record.manager = david - - If the assignment happens from the having side, the assigned object is automatically saved. So in the example above, the - project_id attribute on david would be set to the id of active_record, then david would be saved. - -* Added natural object-style assignment for has_many associations [Florian Weber]. Consider the following model: - - class Project < ActiveRecord::Base - has_many :milestones - end - - class Milestone < ActiveRecord::Base - belongs_to :project - end - - Earlier, assignments would work like following regardless of which way the assignment told the best story: - - deadline.project_id = active_record.id - - Now you can do it either from the belonging side: - - deadline.project = active_record - - ...or from the having side: - - active_record.milestones << deadline - - The milestone is automatically saved with the new foreign key. - -* API CHANGE: Attributes for text (or blob or similar) columns will now have unknown classes stored using YAML instead of using - to_s. (Known classes that won't be yamelized are: String, NilClass, TrueClass, FalseClass, Fixnum, Date, and Time). - Likewise, data pulled out of text-based attributes will be attempted converged using Yaml if they have the "--- " header. - This was primarily done to be enable the storage of hashes and arrays without wrapping them in aggregations, so now you can do: - - user = User.find(1) - user.preferences = { "background" => "black", "display" => large } - user.save - - User.find(1).preferences # => { "background" => "black", "display" => large } - - Please note that this method should only be used when you don't care about representing the object in proper columns in - the database. A money object consisting of an amount and a currency is still a much better fit for a value object done through - aggregations than this new option. - -* POSSIBLE CODE BREAKAGE: As a consequence of the lazy type conversions, it's a bad idea to reference the @attributes hash - directly (it always was, but now it's paramount that you don't). If you do, you won't get the type conversion. So to implement - new accessors for existing attributes, use read_attribute(attr_name) and write_attribute(attr_name, value) instead. Like this: - - class Song < ActiveRecord::Base - # Uses an integer of seconds to hold the length of the song - - def length=(minutes) - write_attribute("length", minutes * 60) - end - - def length - read_attribute("length") / 60 - end - end - - The clever kid will notice that this opens a door to sidestep the automated type conversion by using @attributes directly. - This is not recommended as read/write_attribute may be granted additional responsibilities in the future, but if you think - you know what you're doing and aren't afraid of future consequences, this is an option. - -* Applied a few minor bug fixes reported by Daniel Von Fange. - - -*0.8.4* - -_Reflection_ - -* Added ActiveRecord::Reflection with a bunch of methods and classes for reflecting in aggregations and associations. - -* Added Base.columns and Base.content_columns which returns arrays of column description (type, default, etc) objects. - -* Added Base#attribute_names which returns an array of names for the attributes available on the object. - -* Added Base#column_for_attribute(name) which returns the column description object for the named attribute. - - -_Misc_ - -* Added multi-parameter assignment: - - # Instantiate objects for all attribute classes that needs more than one constructor parameter. This is done - # by calling new on the column type or aggregation type (through composed_of) object with these parameters. - # So having the pairs written_on(1) = "2004", written_on(2) = "6", written_on(3) = "24", will instantiate - # written_on (a date type) with Date.new("2004", "6", "24"). You can also specify a typecast character in the - # parenteses to have the parameters typecasted before they're used in the constructor. Use i for Fixnum, f for Float, - # s for String, and a for Array. - - This is incredibly useful for assigning dates from HTML drop-downs of month, year, and day. - -* Fixed bug with custom primary key column name and Base.find on multiple parameters. - -* Fixed bug with dependent option on has_one associations if there was no associated object. - - -*0.8.3* - -_Transactions_ - -* Added transactional protection for destroy (important for the new :dependent option) [Suggested by Carl Youngblood] - -* Fixed so transactions are ignored on MyISAM tables for MySQL (use InnoDB to get transactions) - -* Changed transactions so only exceptions will cause a rollback, not returned false. - - -_Mapping_ - -* Added support for non-integer primary keys [Aredridel/earlier work by Michael Neumann] - - User.find "jdoe" - Product.find "PDKEY-INT-12" - -* Added option to specify naming method for primary key column. ActiveRecord::Base.primary_key_prefix_type can either - be set to nil, :table_name, or :table_name_with_underscore. :table_name will assume that Product class has a primary key - of "productid" and :table_name_with_underscore will assume "product_id". The default nil will just give "id". - -* Added an overwriteable primary_key method that'll instruct AR to the name of the - id column [Aredridele/earlier work by Guan Yang] - - class Project < ActiveRecord::Base - def self.primary_key() "project_id" end - end - -* Fixed that Active Records can safely associate inside and out of modules. - - class MyApplication::Account < ActiveRecord::Base - has_many :clients # will look for MyApplication::Client - has_many :interests, :class_name => "Business::Interest" # will look for Business::Interest - end - -* Fixed that Active Records can safely live inside modules [Aredridel] - - class MyApplication::Account < ActiveRecord::Base - end - - -_Misc_ - -* Added freeze call to value object assignments to ensure they remain immutable [Spotted by Gavin Sinclair] - -* Changed interface for specifying observed class in observers. Was OBSERVED_CLASS constant, now is - observed_class() class method. This is more consistant with things like self.table_name(). Works like this: - - class AuditObserver < ActiveRecord::Observer - def self.observed_class() Account end - def after_update(account) - AuditTrail.new(account, "UPDATED") - end - end - - [Suggested by Gavin Sinclair] - -* Create new Active Record objects by setting the attributes through a block. Like this: - - person = Person.new do |p| - p.name = 'Freddy' - p.age = 19 - end - - [Suggested by Gavin Sinclair] - - -*0.8.2* - -* Added inheritable callback queues that can ensure that certain callback methods or inline fragments are - run throughout the entire inheritance hierarchy. Regardless of whether a descendant overwrites the callback - method: - - class Topic < ActiveRecord::Base - before_destroy :destroy_author, 'puts "I'm an inline fragment"' - end - - Learn more in link:classes/ActiveRecord/Callbacks.html - -* Added :dependent option to has_many and has_one, which will automatically destroy associated objects when - the holder is destroyed: - - class Album < ActiveRecord::Base - has_many :tracks, :dependent => true - end - - All the associated tracks are destroyed when the album is. - -* Added Base.create as a factory that'll create, save, and return a new object in one step. - -* Automatically convert strings in config hashes to symbols for the _connection methods. This allows you - to pass the argument hashes directly from yaml. (Luke) - -* Fixed the install.rb to include simple.rb [Spotted by Kevin Bullock] - -* Modified block syntax to better follow our code standards outlined in - http://www.rubyonrails.org/CodingStandards - - -*0.8.1* - -* Added object-level transactions [Austin Ziegler] - -* Changed adapter-specific connection methods to use centralized ActiveRecord::Base.establish_connection, - which is parametized through a config hash with symbol keys instead of a regular parameter list. - This will allow for database connections to be opened in a more generic fashion. (Luke) - - NOTE: This requires all *_connections to be updated! Read more in: - http://ar.rubyonrails.org/classes/ActiveRecord/Base.html#M000081 - -* Fixed SQLite adapter so objects fetched from has_and_belongs_to_many have proper attributes - (t.name is now name). [Spotted by Garrett Rooney] - -* Fixed SQLite adapter so dates are returned as Date objects, not Time objects [Spotted by Gavin Sinclair] - -* Fixed requirement of date class, so date conversions are succesful regardless of whether you - manually require date or not. - - -*0.8.0* - -* Added transactions - -* Changed Base.find to also accept either a list (1, 5, 6) or an array of ids ([5, 7]) - as parameter and then return an array of objects instead of just an object - -* Fixed method has_collection? for has_and_belongs_to_many macro to behave as a - collection, not an association - -* Fixed SQLite adapter so empty or nil values in columns of datetime, date, or time type - aren't treated as current time [Spotted by Gavin Sinclair] - - -*0.7.6* - -* Fixed the install.rb to create the lib/active_record/support directory [Spotted by Gavin Sinclair] -* Fixed that has_association? would always return true [Daniel Von Fange] diff --git a/activerecord/CHANGELOG.md b/activerecord/CHANGELOG.md new file mode 100644 index 0000000000000..4fb1e36517643 --- /dev/null +++ b/activerecord/CHANGELOG.md @@ -0,0 +1,521 @@ +## Rails 3.1.8 (Aug 9, 2012) + +* No changes. + +## Rails 3.1.7 (Jul 26, 2012) + +* No changes. + +## Rails 3.1.6 (Jun 12, 2012) + +* protect against the nesting of hashes changing the + table context in the next call to build_from_hash.

Thanks + Paul Battley for reporting. + + *Jon Leighton* + +* ActiveRecord::MacroReflection::AssociationReflection#build_record has a new method signature. + + Before: def build_association(*options) + After: def build_association(*options, &block) + + Users who are redefining this method to extend functionality should ensure that the block is + passed through to ActiveRecord::Base#new. + + This change is necessary to fix https://github.com/rails/rails/issues/1842. + + A deprecation warning and workaround has been added to 3.1, but authors will need to update + their code for it to work correctly in 3.2. + + *Jon Leighton* + +* AR#pluralize_table_names can be used to singularize/pluralize table name of an individual model: + + class User < ActiveRecord::Base + self.pluralize_table_names = false + end + + Previously this could only be set globally for all models through ActiveRecord::Base.pluralize_table_names. *Guillermo Iguaran* + +* Add block setting of attributes to singular associations: + + class User < ActiveRecord::Base + has_one :account + end + + user.build_account{ |a| a.credit_limit => 100.0 } + + The block is called after the instance has been initialized. *Andrew White* + +* Add ActiveRecord::Base.attribute_names to return a list of attribute names. This will return an empty array if the model is abstract or table does not exists. *Prem Sichanugrist* + +* CSV Fixtures are deprecated and support will be removed in Rails 3.2.0 + +* AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes! all accept a second hash as option that allows you + to specify which role to consider when assigning attributes. This is built on top of ActiveModel's + new mass assignment capabilities: + + class Post < ActiveRecord::Base + attr_accessible :title + attr_accessible :title, :published_at, :as => :admin + end + + Post.new(params[:post], :as => :admin) + + assign_attributes() with similar API was also added and attributes=(params, guard) was deprecated. + + Please note that this changes the method signatures for AR#new, AR#create, AR#create!, AR#update_attributes and AR#update_attributes!. If you have overwritten these methods you should update them accordingly. + + *Josh Kalderimis* + +* default_scope can take a block, lambda, or any other object which responds to `call` for lazy + evaluation: + + default_scope { ... } + default_scope lambda { ... } + default_scope method(:foo) + + This feature was originally implemented by Tim Morgan, but was then removed in favour of + defining a 'default_scope' class method, but has now been added back in by Jon Leighton. + The relevant lighthouse ticket is #1812. + +* Default scopes are now evaluated at the latest possible moment, to avoid problems where + scopes would be created which would implicitly contain the default scope, which would then + be impossible to get rid of via Model.unscoped. + + Note that this means that if you are inspecting the internal structure of an + ActiveRecord::Relation, it will *not* contain the default scope, though the resulting + query will do. You can get a relation containing the default scope by calling + ActiveRecord#with_default_scope, though this is not part of the public API. + + *Jon Leighton* + +* If you wish to merge default scopes in special ways, it is recommended to define your default + scope as a class method and use the standard techniques for sharing code (inheritance, mixins, + etc.): + + class Post < ActiveRecord::Base + def self.default_scope + where(:published => true).where(:hidden => false) + end + end + + *Jon Leighton* + +* PostgreSQL adapter only supports PostgreSQL version 8.2 and higher. + +* ConnectionManagement middleware is changed to clean up the connection pool + after the rack body has been flushed. + +* Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks. + It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of + the updated_at column. It should not be called on new records. + Example: + + User.first.update_column(:name, "sebastian") # => true + + *Sebastian Martinez* + +* Associations with a :through option can now use *any* association as the + through or source association, including other associations which have a + :through option and has_and_belongs_to_many associations + + *Jon Leighton* + +* The configuration for the current database connection is now accessible via + ActiveRecord::Base.connection_config. *fxn* + +* limits and offsets are removed from COUNT queries unless both are supplied. + For example: + + People.limit(1).count # => 'SELECT COUNT(*) FROM people' + People.offset(1).count # => 'SELECT COUNT(*) FROM people' + People.limit(1).offset(1).count # => 'SELECT COUNT(*) FROM people LIMIT 1 OFFSET 1' + + *lighthouse #6262* + +* ActiveRecord::Associations::AssociationProxy has been split. There is now an Association class + (and subclasses) which are responsible for operating on associations, and then a separate, + thin wrapper called CollectionProxy, which proxies collection associations. + + This prevents namespace pollution, separates concerns, and will allow further refactorings. + + Singular associations (has_one, belongs_to) no longer have a proxy at all. They simply return + the associated record or nil. This means that you should not use undocumented methods such + as bob.mother.create - use bob.create_mother instead. + + *Jon Leighton* + +* Make has_many :through associations work correctly when you build a record and then save it. This + requires you to set the :inverse_of option on the source reflection on the join model, like so: + + class Post < ActiveRecord::Base + has_many :taggings + has_many :tags, :through => :taggings + end + + class Tagging < ActiveRecord::Base + belongs_to :post + belongs_to :tag, :inverse_of => :tagging # :inverse_of must be set! + end + + class Tag < ActiveRecord::Base + has_many :taggings + has_many :posts, :through => :taggings + end + + post = Post.first + tag = post.tags.build :name => "ruby" + tag.save # will save a Taggable linking to the post + + *Jon Leighton* + +* Support the :dependent option on has_many :through associations. For historical and practical + reasons, :delete_all is the default deletion strategy employed by association.delete(*records), + despite the fact that the default strategy is :nullify for regular has_many. Also, this only + works at all if the source reflection is a belongs_to. For other situations, you should directly + modify the through association. + + *Jon Leighton* + +* Changed the behaviour of association.destroy for has_and_belongs_to_many and has_many :through. + From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link', + not (necessarily) 'get rid of the associated records'. + + Previously, has_and_belongs_to_many.destroy(*records) would destroy the records themselves. It + would not delete any records in the join table. Now, it deletes the records in the join table. + + Previously, has_many_through.destroy(*records) would destroy the records themselves, and the + records in the join table. [Note: This has not always been the case; previous version of Rails + only deleted the records themselves.] Now, it destroys only the records in the join table. + + Note that this change is backwards-incompatible to an extent, but there is unfortunately no + way to 'deprecate' it before changing it. The change is being made in order to have + consistency as to the meaning of 'destroy' or 'delete' across the different types of associations. + + If you wish to destroy the records themselves, you can do records.association.each(&:destroy) + + *Jon Leighton* + +* Add :bulk => true option to change_table to make all the schema changes defined in change_table block using a single ALTER statement. *Pratik Naik* + + Example: + + change_table(:users, :bulk => true) do |t| + t.string :company_name + t.change :birthdate, :datetime + end + + This will now result in: + + ALTER TABLE `users` ADD COLUMN `company_name` varchar(255), CHANGE `updated_at` `updated_at` datetime DEFAULT NULL + +* Removed support for accessing attributes on a has_and_belongs_to_many join table. This has been + documented as deprecated behaviour since April 2006. Please use has_many :through instead. + *Jon Leighton* + +* Added a create_association! method for has_one and belongs_to associations. *Jon Leighton* + +* Migration files generated from model and constructive migration generators + (for example, add_name_to_users) use the reversible migration's `change` + method instead of the ordinary `up` and `down` methods. *Prem Sichanugrist* + +* Removed support for interpolating string SQL conditions on associations. Instead, you should + use a proc, like so: + + Before: + + has_many :things, :conditions => 'foo = #{bar}' + + After: + + has_many :things, :conditions => proc { "foo = #{bar}" } + + Inside the proc, 'self' is the object which is the owner of the association, unless you are + eager loading the association, in which case 'self' is the class which the association is within. + + You can have any "normal" conditions inside the proc, so the following will work too: + + has_many :things, :conditions => proc { ["foo = ?", bar] } + + Previously :insert_sql and :delete_sql on has_and_belongs_to_many association allowed you to call + 'record' to get the record being inserted or deleted. This is now passed as an argument to + the proc. + +* Added ActiveRecord::Base#has_secure_password (via ActiveModel::SecurePassword) to encapsulate dead-simple password usage with BCrypt encryption and salting [DHH]. Example: + + # Schema: User(name:string, password_digest:string, password_salt:string) + class User < ActiveRecord::Base + has_secure_password + end + + user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch") + user.save # => false, password required + user.password = "mUc3m00RsqyRe" + user.save # => false, confirmation doesn't match + user.password_confirmation = "mUc3m00RsqyRe" + user.save # => true + user.authenticate("notright") # => false + user.authenticate("mUc3m00RsqyRe") # => user + User.find_by_name("david").try(:authenticate, "notright") # => nil + User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user + + +* When a model is generated add_index is added by default for belongs_to or references columns + + rails g model post user:belongs_to will generate the following: + + class CreatePosts < ActiveRecord::Migration + def change + create_table :posts do |t| + t.belongs_to :user + t.timestamps + end + add_index :posts, :user_id + end + end + + *Santiago Pastorino* + +* Setting the id of a belongs_to object will update the reference to the + object. *#2989 state:resolved* + +* ActiveRecord::Base#dup and ActiveRecord::Base#clone semantics have changed + to closer match normal Ruby dup and clone semantics. + +* Calling ActiveRecord::Base#clone will result in a shallow copy of the record, + including copying the frozen state. No callbacks will be called. + +* Calling ActiveRecord::Base#dup will duplicate the record, including calling + after initialize hooks. Frozen state will not be copied, and all associations + will be cleared. A duped record will return true for new_record?, have a nil + id field, and is saveable. + +* Migrations can be defined as reversible, meaning that the migration system + will figure out how to reverse your migration. To use reversible migrations, + just define the "change" method. For example: + + class MyMigration < ActiveRecord::Migration + def change + create_table(:horses) do + t.column :content, :text + t.column :remind_at, :datetime + end + end + end + + Some things cannot be automatically reversed for you. If you know how to + reverse those things, you should define 'up' and 'down' in your migration. If + you define something in `change` that cannot be reversed, an + IrreversibleMigration exception will be raised when going down. + +* Migrations should use instance methods rather than class methods: + class FooMigration < ActiveRecord::Migration + def up + ... + end + end + + *Aaron Patterson* + +* has_one maintains the association with separate after_create/after_update instead + of a single after_save. *fxn* + +* The following code: + + Model.limit(10).scoping { Model.count } + + now generates the following SQL: + + SELECT COUNT(*) FROM models LIMIT 10 + + This may not return what you want. Instead, you may with to do something + like this: + + Model.limit(10).scoping { Model.all.size } + + *Aaron Patterson* + +Please check [3-0-stable](https://github.com/rails/rails/blob/3-0-stable/activerecord/CHANGELOG) for previous changes. diff --git a/activerecord/MIT-LICENSE b/activerecord/MIT-LICENSE index 86bcb23b7cf93..c73d1af0969e5 100644 --- a/activerecord/MIT-LICENSE +++ b/activerecord/MIT-LICENSE @@ -1,4 +1,4 @@ -Copyright (c) 2004-2010 David Heinemeier Hansson +Copyright (c) 2004-2011 David Heinemeier Hansson Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the diff --git a/activerecord/README.rdoc b/activerecord/README.rdoc index 101a595ecdda2..1c114e7c086e0 100644 --- a/activerecord/README.rdoc +++ b/activerecord/README.rdoc @@ -3,7 +3,7 @@ Active Record connects classes to relational database tables to establish an almost zero-configuration persistence layer for applications.

YAML fixtures -# 2. CSV fixtures -# 3. Single-file fixtures -# -# == YAML fixtures -# -# This type of fixture is in YAML format and the preferred default. YAML is a file format which describes data structures -# in a non-verbose, human-readable format. It ships with Ruby 1.8.1+. -# -# Unlike single-file fixtures, YAML fixtures are stored in a single file per model, which are placed -# in the directory appointed by ActiveSupport::TestCase.fixture_path=(path) (this is -# automatically configured for Rails, so you can just put your files in /test/fixtures/). -# The fixture file ends with the .yml file extension (Rails example: -# /test/fixtures/web_sites.yml). The format of a YAML fixture file looks like this: -# -# rubyonrails: -# id: 1 -# name: Ruby on Rails -# url: http://www.rubyonrails.org -# -# google: -# id: 2 -# name: Google -# url: http://www.google.com -# -# This YAML fixture file includes two fixtures. Each YAML fixture (ie. record) is given a name and is followed by an -# indented list of key/value pairs in the "key: value" format. Records are separated by a blank line for your viewing -# pleasure. -# -# Note that YAML fixtures are unordered. If you want ordered fixtures, use the omap YAML type. -# See http://yaml.org/type/omap.html -# for the specification. You will need ordered fixtures when you have foreign key constraints on keys in the same table. -# This is commonly needed for tree structures. Example: -# -# --- !omap -# - parent: -# id: 1 -# parent_id: NULL -# title: Parent -# - child: -# id: 2 -# parent_id: 1 -# title: Child -# -# == CSV fixtures -# -# Fixtures can also be kept in the Comma Separated Value (CSV) format. Akin to YAML fixtures, CSV fixtures are stored -# in a single file, but instead end with the .csv file extension -# (Rails example: /test/fixtures/web_sites.csv). -# -# The format of this type of fixture file is much more compact than the others, but also a little harder to read by us -# humans. The first line of the CSV file is a comma-separated list of field names. The rest of the -# file is then comprised -# of the actual data (1 per line). Here's an example: -# -# id, name, url -# 1, Ruby On Rails, http://www.rubyonrails.org -# 2, Google, http://www.google.com -# -# Should you have a piece of data with a comma character in it, you can place double quotes around that value. If you -# need to use a double quote character, you must escape it with another double quote. -# -# Another unique attribute of the CSV fixture is that it has *no* fixture name like the other two formats. Instead, the -# fixture names are automatically generated by deriving the class name of the fixture file and adding an incrementing -# number to the end. In our example, the 1st fixture would be called "web_site_1" and the 2nd one would be called -# "web_site_2". -# -# Most databases and spreadsheets support exporting to CSV format, so this is a great format for you to choose if you -# have existing data somewhere already. -# -# == Single-file fixtures -# -# This type of fixture was the original format for Active Record that has since been deprecated in -# favor of the YAML and CSV formats. -# Fixtures for this format are created by placing text files in a sub-directory (with the name of the model) -# to the directory appointed by ActiveSupport::TestCase.fixture_path=(path) (this is automatically -# configured for Rails, so you can just put your files in /test/fixtures// -- -# like /test/fixtures/web_sites/ for the WebSite model). -# -# Each text file placed in this directory represents a "record". Usually these types of fixtures are named without -# extensions, but if you are on a Windows machine, you might consider adding .txt as the extension. -# Here's what the above example might look like: -# -# web_sites/google -# web_sites/yahoo.txt -# web_sites/ruby-on-rails -# -# The file format of a standard fixture is simple. Each line is a property (or column in db speak) and has the syntax -# of "name => value". Here's an example of the ruby-on-rails fixture above: -# -# id => 1 -# name => Ruby on Rails -# url => http://www.rubyonrails.org -# -# = Using fixtures in testcases -# -# Since fixtures are a testing construct, we use them in our unit and functional tests. There are two ways to use the -# fixtures, but first let's take a look at a sample unit test: -# -# require 'test_helper' -# -# class WebSiteTest < ActiveSupport::TestCase -# test "web_site_count" do -# assert_equal 2, WebSite.count -# end -# end -# -# By default, the test_helper module will load all of your fixtures into your test database, -# so this test will succeed. -# The testing environment will automatically load the all fixtures into the database before each test. -# To ensure consistent data, the environment deletes the fixtures before running the load. -# -# In addition to being available in the database, the fixture's data may also be accessed by -# using a special dynamic method, which has the same name as the model, and accepts the -# name of the fixture to instantiate: -# -# test "find" do -# assert_equal "Ruby on Rails", web_sites(:rubyonrails).name -# end -# -# Alternatively, you may enable auto-instantiation of the fixture data. For instance, take the following tests: -# -# test "find_alt_method_1" do -# assert_equal "Ruby on Rails", @web_sites['rubyonrails']['name'] -# end -# -# test "find_alt_method_2" do -# assert_equal "Ruby on Rails", @rubyonrails.news -# end -# -# In order to use these methods to access fixtured data within your testcases, you must specify one of the -# following in your ActiveSupport::TestCase-derived class: -# -# - to fully enable instantiated fixtures (enable alternate methods #1 and #2 above) -# self.use_instantiated_fixtures = true -# -# - create only the hash for the fixtures, do not 'find' each instance (enable alternate method #1 only) -# self.use_instantiated_fixtures = :no_instances -# -# Using either of these alternate methods incurs a performance hit, as the fixtured data must be fully -# traversed in the database to create the fixture hash and/or instance variables. This is expensive for -# large sets of fixtured data. -# -# = Dynamic fixtures with ERb -# -# Some times you don't care about the content of the fixtures as much as you care about the volume. In these cases, you can -# mix ERb in with your YAML or CSV fixtures to create a bunch of fixtures for load testing, like: -# -# <% for i in 1..1000 %> -# fix_<%= i %>: -# id: <%= i %> -# name: guy_<%= 1 %> -# <% end %> -# -# This will create 1000 very simple YAML fixtures. -# -# Using ERb, you can also inject dynamic values into your fixtures with inserts like <%= Date.today.strftime("%Y-%m-%d") %>. -# This is however a feature to be used with some caution. The point of fixtures are that they're -# stable units of predictable sample data. If you feel that you need to inject dynamic values, then -# perhaps you should reexamine whether your application is properly testable. Hence, dynamic values -# in fixtures are to be considered a code smell. -# -# = Transactional fixtures -# -# TestCases can use begin+rollback to isolate their changes to the database instead of having to -# delete+insert for every test case. -# -# class FooTest < ActiveSupport::TestCase -# self.use_transactional_fixtures = true -# -# test "godzilla" do -# assert !Foo.find(:all).empty? -# Foo.destroy_all -# assert Foo.find(:all).empty? -# end -# -# test "godzilla aftermath" do -# assert !Foo.find(:all).empty? -# end -# end -# -# If you preload your test database with all fixture data (probably in the Rakefile task) and use transactional fixtures, -# then you may omit all fixtures declarations in your test cases since all the data's already there -# and every case rolls back its changes. -# -# In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to true. This will provide -# access to fixture data for every table that has been loaded through fixtures (depending on the -# value of +use_instantiated_fixtures+) -# -# When *not* to use transactional fixtures: -# -# 1. You're testing whether a transaction works correctly. Nested transactions don't commit until -# all parent transactions commit, particularly, the fixtures transaction which is begun in setup -# and rolled back in teardown. Thus, you won't be able to verify -# the results of your transaction until Active Record supports nested transactions or savepoints (in progress). -# 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM. -# Use InnoDB, MaxDB, or NDB instead. -# -# = Advanced YAML Fixtures -# -# YAML fixtures that don't specify an ID get some extra features: -# -# * Stable, autogenerated IDs -# * Label references for associations (belongs_to, has_one, has_many) -# * HABTM associations as inline lists -# * Autofilled timestamp columns -# * Fixture label interpolation -# * Support for YAML defaults -# -# == Stable, autogenerated IDs -# -# Here, have a monkey fixture: -# -# george: -# id: 1 -# name: George the Monkey -# -# reginald: -# id: 2 -# name: Reginald the Pirate -# -# Each of these fixtures has two unique identifiers: one for the database -# and one for the humans.

Since Active Record can figure out the ID of -# any fixture from its label, you can specify FK's by label instead of ID. -# -# === belongs_to -# -# Let's break out some more monkeys and pirates. -# -# ### in pirates.yml -# -# reginald: -# id: 1 -# name: Reginald the Pirate -# monkey_id: 1 -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# pirate_id: 1 -# -# Add a few more monkeys and pirates and break this into multiple files, -# and it gets pretty hard to keep track of what's going on.

Something -# like this should look familiar: -# -# ### in fruit.rb -# -# belongs_to :eater, :polymorphic => true -# -# ### in fruits.yml -# -# apple: -# id: 1 -# name: apple -# eater_id: 1 -# eater_type: Monkey -# -# Can we do better? You bet! -# -# apple: -# eater: george (Monkey) -# -# Just provide the polymorphic target type and Active Record will take care of the rest. -# -# === has_and_belongs_to_many -# -# Time to give our monkey some fruit. -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# -# ### in fruits.yml -# -# apple: -# id: 1 -# name: apple -# -# orange: -# id: 2 -# name: orange -# -# grape: -# id: 3 -# name: grape -# -# ### in fruits_monkeys.yml -# -# apple_george: -# fruit_id: 1 -# monkey_id: 1 -# -# orange_george: -# fruit_id: 2 -# monkey_id: 1 -# -# grape_george: -# fruit_id: 3 -# monkey_id: 1 -# -# Let's make the HABTM fixture go away. -# -# ### in monkeys.yml -# -# george: -# id: 1 -# name: George the Monkey -# fruits: apple, orange, grape -# -# ### in fruits.yml -# -# apple: -# name: apple -# -# orange: -# name: orange -# -# grape: -# name: grape -# -# Zap! No more fruits_monkeys.yml file. We've specified the list of fruits -# on George's fixture, but we could've just as easily specified a list -# of monkeys on each fruit. As with +belongs_to+, Active Record reflects on -# the fixture's model class and discovers the +has_and_belongs_to_many+ -# associations. -# -# == Autofilled timestamp columns -# -# If your table/model specifies any of Active Record's -# standard timestamp columns (+created_at+, +created_on+, +updated_at+, +updated_on+), -# they will automatically be set to Time.now. -# -# If you've set specific values, they'll be left alone. -# -# == Fixture label interpolation -# -# The label of the current fixture is always available as a column value: -# -# geeksomnia: -# name: Geeksomnia's Account -# subdomain: $LABEL -# -# Also, sometimes (like when porting older join table fixtures) you'll need -# to be able to get a hold of the identifier for a given label.

This is expensive for + # large sets of fixtured data. + # + # = Dynamic fixtures with ERB + # + # Some times you don't care about the content of the fixtures as much as you care about the volume. + # In these cases, you can mix ERB in with your YAML fixtures to create a bunch of fixtures for load + # testing, like: + # + # <% 1.upto(1000) do |i| %> + # fix_<%= i %>: + # id: <%= i %> + # name: guy_<%= 1 %> + # <% end %> + # + # This will create 1000 very simple fixtures. + # + # Using ERB, you can also inject dynamic values into your fixtures with inserts like + # <%= Date.today.strftime("%Y-%m-%d") %>. + # This is however a feature to be used with some caution. The point of fixtures are that they're + # stable units of predictable sample data. If you feel that you need to inject dynamic values, then + # perhaps you should reexamine whether your application is properly testable. Hence, dynamic values + # in fixtures are to be considered a code smell. + # + # = Transactional Fixtures + # + # Test cases can use begin+rollback to isolate their changes to the database instead of having to + # delete+insert for every test case. + # + # class FooTest < ActiveSupport::TestCase + # self.use_transactional_fixtures = true + # + # test "godzilla" do + # assert !Foo.all.empty? + # Foo.destroy_all + # assert Foo.all.empty? + # end + # + # test "godzilla aftermath" do + # assert !Foo.all.empty? + # end + # end + # + # If you preload your test database with all fixture data (probably in the rake task) and use + # transactional fixtures, then you may omit all fixtures declarations in your test cases since + # all the data's already there and every case rolls back its changes. + # + # In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to + # true. This will provide access to fixture data for every table that has been loaded through + # fixtures (depending on the value of +use_instantiated_fixtures+). + # + # When *not* to use transactional fixtures: + # + # 1. You're testing whether a transaction works correctly. Nested transactions don't commit until + # all parent transactions commit, particularly, the fixtures transaction which is begun in setup + # and rolled back in teardown. Thus, you won't be able to verify + # the results of your transaction until Active Record supports nested transactions or savepoints (in progress). + # 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM. + # Use InnoDB, MaxDB, or NDB instead. + # + # = Advanced Fixtures + # + # Fixtures that don't specify an ID get some extra features: + # + # * Stable, autogenerated IDs + # * Label references for associations (belongs_to, has_one, has_many) + # * HABTM associations as inline lists + # * Autofilled timestamp columns + # * Fixture label interpolation + # * Support for YAML defaults + # + # == Stable, Autogenerated IDs + # + # Here, have a monkey fixture: + # + # george: + # id: 1 + # name: George the Monkey + # + # reginald: + # id: 2 + # name: Reginald the Pirate + # + # Each of these fixtures has two unique identifiers: one for the database + # and one for the humans.

Since Active Record can figure out the ID of + # any fixture from its label, you can specify FK's by label instead of ID. + # + # === belongs_to + # + # Let's break out some more monkeys and pirates. + # + # ### in pirates.yml + # + # reginald: + # id: 1 + # name: Reginald the Pirate + # monkey_id: 1 + # + # ### in monkeys.yml + # + # george: + # id: 1 + # name: George the Monkey + # pirate_id: 1 + # + # Add a few more monkeys and pirates and break this into multiple files, + # and it gets pretty hard to keep track of what's going on.

All is made clear. Active Record reflects on the fixture's model class, + # finds all the +belongs_to+ associations, and allows you to specify + # a target *label* for the *association* (monkey: george) rather than + # a target *id* for the *FK* (monkey_id: 1). + # + # ==== Polymorphic belongs_to + # + # Supporting polymorphic relationships is a little bit more complicated, since + # Active Record needs to know what type your association is pointing at.

No more fruits_monkeys.yml file. We've specified the list of fruits + # on George's fixture, but we could've just as easily specified a list + # of monkeys on each fruit.
