The 3.7 release focuses on improvements to schema generation and the interactive API documentation.
This release has been made possible by Bayer who have sponsored the release.
If you use REST framework commercially and would like to see this work continue, we strongly encourage you to invest in its continued development by
signing up for a paid plan.
The schema generation introduced in 3.5 and the related API docs generation in 3.6 are both hugely powerful features, however they’ve been somewhat limited in cases where the view introspection isn’t able to correctly identify the schema for a particular view.
In order to try to address this we’re now adding the ability for per-view customization of the API schema. The interface that we’re adding for this allows either basic manual overrides over which fields should be included on a view, or for more complex programmatic overriding of the schema generation. We believe this release comprehensively addresses some of the existing shortcomings of the schema features.
Let’s take a quick look at using the new functionality…
APIView class has a
schema attribute, that is used to control how the Schema for that particular view is generated. The default behaviour is to use the
from rest_framework.views import APIView from rest_framework.schemas import AutoSchema class CustomView(APIView): schema = AutoSchema() # Included for demonstration only. This is the default behavior.
We can remove a view from the API schema and docs, like so:
class CustomView(APIView): schema = None
If we want to mostly use the default behavior, but additionally include some additional fields on a particular view, we can now do so easily…
class CustomView(APIView): schema = AutoSchema(manual_fields=[ coreapi.Field('search', location='query') ])
To ignore the automatic generation for a particular view, and instead specify the schema explicitly, we use the
ManualSchema class instead…
class CustomView(APIView): schema = ManualSchema(fields=[...])
For more advanced behaviors you can subclass
AutoSchema to provide for customized schema generation, and apply that to particular views.
class CustomView(APIView): schema = CustomizedSchemaGeneration()
For full details on the new functionality, please see the Schema Documentation.
REST framework 3.7 supports Django versions 1.10, 1.11, and 2.0 alpha.
There are a large number of minor fixes and improvements in this release. See the release notes page for a complete listing.
The number of open tickets against the project currently at its lowest number in quite some time, and we’re continuing to focus on reducing these to a manageable amount.

We’re still planning to work on improving real-time support for REST framework by providing documentation on integrating with Django channels, as well adding support for more easily adding WebSocket support to existing HTTP endpoints.
This will likely be timed so that any REST framework development here ties in with similar work on API Star.
