Error raised when sending OPTIONS request to relationship view

[valerymelou]

Hi.
I'm trying to send an OPTIONS request to a relationship view and the server raises a RuntimeError saying ResourceIdentifierObjectsSerializer must be initialized with a model class. I took a look in the code and I don't see how RelationshipView may specify the model class explicitly or implicitly. I don't have too much experience with the package itself so could someone please take a look at this?

See the declaration of ResourceIdentifierObjectSerializer where it looks like the model_class and instance have to be provided as an optional argument. In the debugger, neither is set. I'm not quite sure where that is supposed to happen. Will try to find it.

The is based on iterating through a RelationShipView's fields which was happening because I was
trying to use coreapi rest_framework.schemas.get_schema_view.

The relevant call tree is:

rest_framework.GenericAPIView.get_serializer
rest_framework.AutoSchema.get_serializer_fields

I added a serializer_class and this appears to have fixed it:

class WidgetRelationshipView(RelationshipView):
    queryset = Widget.objects
    serializer_class = WidgetSerializer # <<<--- add this
    self_link_view_name = 'widget-relationships'

But the response for coreapi and swagger are both based on application/json and not application/vnd.api+json so it's the coreapi schema, not jsonapi's.
