[Solved]-Django/Python: Update the relation to point at settings.AUTH_USER_MODEL

in settings_example.py you have AUTH_USER_MODEL = 'users.User'. However you are using an app – menu.bookmark – that has a relation to django.contrib.auth.User – you can’t have both. Setting AUTH_USER_MODEL means that you are replacing the built-in Django user model with your own. See http://procrastinatingdev.com/django/using-configurable-user-models-in-django-1-5/ for details.
