Multiple detail_route for the same url_path

[cancan101]

I would like to have multiple detail_route for the same url_path but with different HTTP methods. I would like to do this so that I may specify different permission_classes.

    @detail_route(methods=['post'], url_path='users', permission_classes=[A])
    def users_create(self, request, **kwargs):
        data = request.data
        serializer = UserSerializer(data=data)
        serializer.is_valid(raise_exception=True)

        user = serializer.validated_data

        return Response(serializer.data, status=status.HTTP_201_CREATED)

    @detail_route(methods=['get'], url_path='users', permission_classes=[B])
    def users_list(self, request, **kwargs):
        serializer = UserSerializer(data=[], many=True)
        serializer.is_valid(raise_exception=True)
        return Response(serializer.data, status=status.HTTP_200_OK)

Unfortunately this does not seem to work in the browseable API:

HTTP 405 METHOD NOT ALLOWED
Content-Type: application/json
Vary: Accept
Allow: POST, OPTIONS

{
    "detail": "Method \"GET\" not allowed."
}

This is a usage question that you should really post on the mailing list...

Nonetheless, override APIView.get_permissions to inspect the request and return the appropriate permissions for the method.

Forgetting for a moment even wanting to have different permission classes, why is this not supported (and I don't think this is a usage question):

    @detail_route(methods=['post'], url_path='users')
    def users_create(self, request, **kwargs):
        data = request.data
        serializer = UserSerializer(data=data)
        serializer.is_valid(raise_exception=True)

        user = serializer.validated_data

        return Response(serializer.data, status=status.HTTP_201_CREATED)

    @detail_route(methods=['get'], url_path='users')
    def users_list(self, request, **kwargs):
        serializer = UserSerializer(data=[], many=True)
        serializer.is_valid(raise_exception=True)
        return Response(serializer.data, status=status.HTTP_200_OK)

@cancan101 that request seems similar to what #2820 is trying to accomplish.
