Django rest framework- calling another class-based view


I have pored over several similar posts (and Calling a class-based view of an app from another app in same project seemed promising, but does not work), but some are older and none quite work for me. Here's my setup (using Django==2.0.6, djangorestframework==3.8.2)

I have a basic model (simplified here):

from django.db import models class Resource(models.Model): name = models.CharField(max_length=100, null=False)

I have a basic endpoint where I can list and create Resource instances:

from rest_framework import generics, permissions from myapp.models import Resource from myapp.serializers import ResourceSerializer class ListAndCreateResource(generics.ListCreateAPIView): queryset = Resource.objects.all() serializer_class = ResourceSerializer permission_classes = (permissions.IsAuthenticated,)

(afaik, the details of the serializer are not relevant, so that is left out).

Anyway, in addition to that basic endpoint, I have another API endpoint which performs some actions, but also creates some Resource objects in the process. Of course, I would like to make use of the functionality encapsulated in the ListAndCreateResource class so I only have to maintain one place where Resources are created.

I have tried:

Attempt 1:

class SomeOtherView(generics.CreateAPIView): def post(self, request, *args, **kwargs): # ... some other functionality... # ... response = ListAndCreateResource().post(request, *args, **kwargs) # ... more functionality... return Response({'message': 'ok'})

Unfortunately, that does not work for me. In my trace, I get:

File "/home/projects/venv/lib/python3.5/site-packages/rest_framework/generics.py", line 111, in get_serializer kwargs['context'] = self.get_serializer_context() File "/home/projects/venv/lib/python3.5/site-packages/rest_framework/generics.py", line 137, in get_serializer_context 'request': self.request, AttributeError: 'ListAndCreateResource' object has no attribute 'request'

Attempt 2: This attempt tries to use the as_view method which is part of all Django class-based views:

class SomeOtherView(generics.CreateAPIView): def post(self, request, *args, **kwargs): # ... some other functionality... # ... response = ListAndCreateResource.as_view()(request, *args, **kwargs) # ... more functionality... return Response({'message': 'ok'})

But that gives up with:

AssertionError: The `request` argument must be an instance of `django.http.HttpRequest`, not `rest_framework.request.Request`

So my question is...is there a straightforward way to do this? I can access the _request attribute of the rest_framework.request.Request object (which is of type django.http.HttpRequest, but then I do not have any of the authentication details that are contained in the DRF Request object (indeed, my ListAndCreateResource returns a 403 if I use response = ListAndCreateResource().as_view()(request._request, *args, **kwargs) in attempt #2 above).

Thanks in advance!


You can access the request with self.request in class based views.
