I have some issues with writing tests against Django REST API framework. I have Python 2.7.6 on Mac OS v.10.10.3, Django==1.6.5 and djangorestframework==3.1.1. I'm trying to write a couple of tests against Django REST framework.
I have a dummy test view for the API:
class TestApiView(APIView):
def get(self, request, format=None):
return Response(status=status.HTTP_404_NOT_FOUND)
It works just fine while I'm calling it:
(venv)bash-3.2# curl -H "Accept: application/json; indent=2" -i --request GET "http://ift.tt/1JcqKCi"
HTTP/1.0 404 NOT FOUND
Date: Thu, 30 Apr 2015 18:35:09 GMT
Server: WSGIServer/0.1 Python/2.7.6
Vary: Accept, Cookie
Allow: GET, HEAD, OPTIONS
But when I want to lunch a Test against that view it raises exception. My test code:
from rest_framework.test import APIClient
client = APIClient()
print client.get('/api/v1/client/test/', format='json')
This code raises exception:
Internal Server Error: /api/v1/client/test/

I have almost the same issue with views based on mixins.ListModelMixin - it works fine, but raises exception during testing.
View definition:
class ListTestView(mixins.ListModelMixin, generics.GenericAPIView):
pagination_class = paginators.StandardResultsSetPagination
def get(self, request, format=None, *args, **kwargs):
self.serializer_class = TestListSerializer
self.queryset = Client.objects.all()
return self.list(request, *args, **kwargs)
Calling this view from the test client:
print client.get('/api/v1/client/list/', format='json')
raises this exception:
Internal Server Error: /api/v1/client/list/

Any suggestions? Many thanks!
