Is it possible to add ability to convert raw dict to reduced dict using schema? #455
Description
jsonschema already have a function validate to validate a raw dict with a schema.
To explain what I mean, for example, there is a dict:
raw_dict = {
"latitude": 48.858093,
"longitude": 2.294694,
"extra_key": "value1"
}
and a schema:
schema = {
"id": "https://example.com/geographical-location.schema.json",
"$schema": "http://json-schema.org/draft-06/schema#",
"title": "Longitude and Latitude Values",
"description": "A geographical coordinate.",
"required": [ "latitude", "longitude" ],
"type": "object",
"properties": {
"latitude": {
"type": "number",
"minimum": -90,
"maximum": 90
},
"longitude": {
"type": "number",
"minimum": -180,
"maximum": 180
}
}
}
Now I want a function which like:
def reduce(instance, schema):
...
return new_instance
>>> reduce(raw_dict, schema)
>>> raw_dict = {
"latitude": 48.858093,
"longitude": 2.294694
}
the reduce function validate the raw_dict and pass it ,then convert it to the result which fit the schema, if the dict is not passed, it behaves like validate, raise an error.
If this function is allowed to add into jsonschema, I can take some time to write it.
