I am getting this error rest_framework.request.WrappedAttributeError

Question

I am trying to upgrade my django 1.9 to django 2.0. It is working fine for GET() but I am getting error in POST(). My views.py is:-

class AccountInfoUpdate(APIView):
    authentication_classes = [IsAuthenticated]

    def post(self, request):
        user = request.user
        user_profile = UserProfile.objects.get(user=user)
        name = False
        contact = False
        if "name" in request.data:
            user_profile.name = request.data.get('name')
            user_profile.save()
            name = True
        if "contact" in request.data:
            user_profile.contact = request.data.get('contact')
            user_profile.save()
            contact = True

        if user_profile.affiliate_code is not None and (name or contact):
            result = service.update_affiliate(user_profile.affiliate_code, name=user_profile.name,
                                                   contact=user_profile.contact)

        return Response({'Message': 'Account info updated successfully!'})

I am getting this error:-

user_auth_tuple = authenticator.authenticate(self)
rest_framework.request.WrappedAttributeError: 'IsAuthenticated' object has no attribute 'authenticate'

If I removed or comment 'rest_framework.authentication.SessionAuthentication', from REST_FRAMEWORK then I am getting this error CSRF Failed: CSRF token missing or incorrect.

I tried permission_classes = [IsAuthenticated] and did fallow on Postman but still getting same error.

Answer 1

IsAuthenticated is a Permission Class not an Authentication class. So it should be as

class AccountInfoUpdate(APIView):
    permission_classes = [IsAuthenticated]
    # your code

UPDATE-1
How to resolve CSRF Failed error

1. Open a new tab in POSTMAN
2. Provide URL(1) 3. Go to Authorization tab(2) and setect Basic Auth then provide your username and password
4. Then go to Body tab, and enter your JSON payload. 5. Hit send button. There you go
