Something to where we can have nginx point to certain views which would service as its own microservice. -

But the view named table_view belongs to another app called table. Both apps belong to the same root. What do I need to set up for the above code to work? -
Testing CSRF protecting views in Django Rest Framework
I was hitting a wall when it comes to testing my APIViews that require authentication. I wanted to test that both CSRF and authentications + permissions were enforced as expected. Some information of my setup: My view is a Django Rest Framework rest_framework.views.APIView which implements the post function. Default authentication classes are SessionAuthentication Default permission classes are IsAuthenticated Test cases use the APIClient to issue requests When initializing the APIClient with enforce_csrf_checks=True I still can't seem to get the response I'm expecting when it comes to views that require authentication (using the IsAuthenticated permission class). For non-authenticated views, I can test CSRF protection, no problem. The view in question: @method_decorator(csrf_protect) def post(self, request, format=None): """ Create a new user. """ serializer = UserSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) The test code: client = APIClient() response = client.post(url, data) # Success! client = APIClient(enforce_csrf_checks=True) response = client.post(url, data) # 403 FORBIDDEN For authenticated views, things get weird (this view uses the IsAuthenticated permission: def get(self, request, format=None): """ Get request user. """ user = User.objects.get(pk=request.user.id) serializer = UserSerializer(user) return Response(serializer.data, status=status.HTTP_200_OK) The test code: self.client = APIClient(enforce_csrf_checks=True) self.client.login(email='t@t.se', password='pw') self.client.get(url) # Succeeds, even though it should not. … -
Celery doesn't work with Django on Heroku. Getting `Cannot connect to amqp://guest:**@127.0.0.1:5672//: [Errno 111] Connection refused` error
I can't seem to get Celery to work with Django using Heroku. I've tried many different combinations of fixes over the past two days and can't seem to get it done. The error that I'm getting is this [2020-10-10 22:29:25,246: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [Errno 111] Connection refused. I use a heroku add-on called Redis Cloud for redis, (hence the celery settings using REDISCLOUD_URL as an environment variable. I'm basically at a complete loss on what to do at this point as I've looked at many tutorials, stackoverflow questions, etc. Thank you.
