If I remove the the import everything goes well. If I cutpaste the code from views.py to interfaces it works too. What am I doing wrong here? This is a classical circular import error. If your views.py, for example, imports interfaces.py, you have a circular import loop between views.py and interfaces.py.

Hi Florian, To get around the circular import error use a marker interface to suit your code. Best regards.
