Deprecations

Router argument/method renamed to use basename for consistency.

• The Router.register base_name argument has been renamed in favor of basename.
• The Router.get_default_base_name method has been renamed in favor of Router.get_default_basename. #5990

See #5990.

base_name and get_default_base_name() are pending deprecation. They will be deprecated in 3.10 and removed entirely in 3.11.

action decorator replaces list_route and detail_route

Both list_route and detail_route are now deprecated in favour of the single action decorator. They will be removed entirely in 3.10.

The action decorator takes a boolean detail argument.

• Replace detail_route uses with @action(detail=True).
• Replace list_route uses with @action(detail=False).

exclude_from_schema

Both APIView.exclude_from_schema and the exclude_from_schema argument to the @api_view have now been removed.

For APIView you should instead set a schema = None attribute on the view class.

For function based views the @schema decorator can be used to exclude the view from the schema, by using @schema(None).
