Question

I have the Error:

Error: One or more models did not validate:
auth.permission: 'content_type' has a relation with model <class 'django.contrib.contenttypes.models.ContentType'>, which has either not been installed or is abstract.

I don’t see anywhere in the package a reference on the django.contrib.contenttypes.models.ContentType.

Even with all models inside a comma i get this error.

I reference user multiple times, but why a content_type error then?

Django==1.4.2

Edit: Because people think my module is named auth, here are the positions where it exists in the whole project:

models.py

2: from django.contrib.auth.models import User

settings.py

94: 'django.contrib.auth.middleware.AuthenticationMiddleware',
112: 'django.contrib.auth',

Answer 1

under settings INSTALLED_APPS there was

'django.contrib.contenttypes',

missing. The link to the ticket from jro was helpful.
