USERS ONLY USER ONLY when using user model, Postgres

I have an application for registering user actions or any actions. So to implement this, I had to use GenericForeignKeys on my model as a number of models could perform actions.

Here's my model:

class Activity(models.Model):
    actor_content_type = models.ForeignKey(
        ContentType, related_name='actor'
    actor_object_id = models.CharField(max_length=500)
    actor = generic.GenericForeignKey(
        ct_field='actor_content_type', fk_field='actor_object_id'
    verb = models.CharField(max_length=50)


I can create posts just fine by passing any model instance to "actor", but when I pass django user model instance I get the following error:

self = <django.db.backends.postgresql_psycopg2.base.DatabaseWrapper object at 0x2d3bfd0>

    def _commit(self):
        if self.connection is not None:
>               return self.connection.commit()
E               IntegrityError: insert or update on table "auth_permission" violates foreign key constraint "content_type_id_refs_id_d043b34a"
E               DETAIL:  Key (content_type_id)=(3) is not present in table "django_content_type".

/usr/local/lib/python2.7/dist-packages/Django-1.5.10-py2.7.egg/django/db/backends/postgresql_psycopg2/ IntegrityError


Can anyone understand why this is happening?

In your settings module, change the order of your INSTALLED_APPS variable so that "django.contrib.auth" is below "django.contrib.contenttypes", for example:
