Breaking Changes

Removed query parameter nullable/required special case

In previous versions, setting either nullable: true or required: false on a query parameter would act like both were set, resulting in a type signature like Union[None, Unset, YourType]. This special case has been removed, query parameters will now act like all other types of parameters.

Renamed body types and parameters

PR #900 addresses #822.

Where previously there would be one body parameter per supported content type, now there is a single body parameter which takes a union of all the possible inputs. This correctly models the fact that only one body can be sent (and ever would be sent) in a request.

For example, when calling a generated endpoint, code which used to look like this:

post_body_multipart.sync_detailed(
    client=client,
    multipart_data=PostBodyMultipartMultipartData(),
)

Will now look like this:

post_body_multipart.sync_detailed(
    client=client,
    body=PostBodyMultipartBody(),
)

Note that both the input parameter name and the class name have changed. This should result in simpler code when there is only a single body type and now produces correct code when there are multiple body types.

Features

OpenAPI 3.1 support

The generator will now attempt to generate code for OpenAPI documents with versions 3.1.x (previously, it would exit immediately on seeing a version other than 3.0.x). The following specific OpenAPI 3.1 features are now supported:

• null as a type
• Arrays of types (e.g., type: [string, null])
• const (defines Literal types)

The generator does not currently validate that the OpenAPI document is valid for a specific version of OpenAPI, so it may be possible to generate code for documents that include both removed 3.0 syntax (e.g., nullable) and new 3.1 syntax (e.g., null as a type).

Thanks to everyone who helped make this possible with discussions and testing, including:

Support multiple possible requestBody

PR #900 addresses #822.

It is now possible in some circumstances to generate valid code for OpenAPI documents which have multiple possible requestBody values. Previously, invalid code could have been generated with no warning (only one body could actually be sent).

Only one content type per "category" is currently supported at a time. The categories are:

• JSON, like application/json
• Binary data, like application/octet-stream
• Encoded form data, like application/x-www-form-urlencoded
• Files, like multipart/form-data

Fixes

Always use correct content type for requests

In previous versions, a request body that was similar to a known content type would use that content type in the request. For example application/json would be used for application/vnd.api+json. This was incorrect and could result in invalid requests being sent.

Now, the content type defined in the OpenAPI document will always be used.
