Django Rest Framework,Filtering objects based on Forignkey relationship

Django Rest Framework - Django ORM instance.delete() doesn't delete the instance...?
I have the following API delete view: @action(detail=True, methods=['delete'], permission_classes=[IsAuthenticatedViaJWTCookie]) def delete(self, request, pk=None, *args, **kwargs): queryset = self.get_queryset().get(id=pk) if queryset.user == request.user: queryset.delete() return Response(status=status.HTTP_204_NO_CONTENT) else: response = standardized_json_error_response( message='Artwork Object Could Not Be Deleted', data=[] ) return Response(data=response, status=status.HTTP_401_UNAUTHORIZED) When calling this view from an axios.delete request, I can see that the delete request is being made, and hitting the endpoint. All good so far. Yet, in the listing API view, the target instance to be deleted is still being listed. Doesn't matter how many times that endpoint is refreshed, or how long I wait. What is worse still, is when I call that endpoint again using axios.delete in the front end, for a second time, the record is then permanently deleted? Has anyone experienced such odd behaviour before with Django, or could this be a third party issue? *I have installed django-cleanup...? -

GraphQL API export of Django project in SDL representation not possible anymore
I'm trying to export the GraphQL API of my backend server with python manage.py graphql_schema --schema <django-app>.schema.schema --out <django-project>/schema.graphql.

It seems like a package I introduced later is the root cause ot this issue. I added the following GraphQL dependencies over time: graphene==2.1.8 graphene-django==2.8.0 graphene-django-cud==0.4.4 graphene-file-upload==1.2.2 graphene-subscriptions==1.0.2 graphql-core==2.3.1 graphql-relay==2.0.1 Had someone else this behavior as well and knows how to fix or workaround it? -
