'type' object is not iterable when I use any decorators

[Shekar Tippur]

Hello,

Here is a decorator that I am trying ot use to restrict access to the class to only super users: Can someone please point me to what could be wrong. If I take the decorator, I am able to get thro but it is not restricted to only super users.

@user_passes_test(lambda u: u.is_superuser)
class UserViewSet(viewsets.ModelViewSet):
    permission_classes = [permissions.TokenHasReadWriteScope]
    queryset = User.objects.all()
    serializer_class = UserSerializer
    model=User

When I use this, I get the error:

'type' object is not iterable

user_passes_test is for decorating functions, not classes

Django Rest Framework has its own system for permissions (and you seem to be already using it)

http://www.django-rest-framework.org/api-guide/permissions/

Use that instead I think
