admin.logentry: 'user' has a relation with model <class 'api.models.User'>, which has either not been installed or is abstract

Question

django 1.5.1

I create custom auth model:

file api/models.py

from django.contrib.auth.models import BaseUserManager, AbstractUser

class User(AbstractUser):

  token = models.CharField(max_length=64, null=False, blank=False, help_text=_('Photo for carte'), unique=True)
  updated_token = models.DateTimeField(auto_now_add=True, help_text=_('Create record'))

  USERNAME_FIELD = 'email'

  objects = MyUserManager()

  def __unicode__(self):
      return "пользователь: %s" % self.email
  class Meta:
      app_label = 'custom_auth'

file settings.py

AUTH_USER_MODEL = 'custom_auth.User'
.....
INSTALLED_APPS = (
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'api',
.....
'south',
'django.contrib.admin',

)

on ./manage.py syncdb I get an error:

admin.logentry: 'user' has a relation with model <class 'api.models.User'>, which has either not been installed or is abstract.

How decide this problem?

Edit 1 tried comment line and make syncdb:

'django.contrib.admin',

syncdb was successful after that tried create user in ./manage.py shell

In [1]: from api.models import User
In [2]: User.objects.create_superuser('[email protected]', 'test')

and recieve error:

DatabaseError: (1146, "Table 'app_name.custom_auth_user' doesn't exist")

Answer 1

You will need to set an app_label on your class which is also in your INSTALLED_APPS: either set app_label = 'api' (the default), or add 'custom_auth' to your INSTALLED_APPS (of course, it needs to be a valid app then).

The validation process in Django tries to get the new User class using get_model, and by default get_model returns models for installed apps only. You can verify with your current code:

>>> loading.get_model('custom_auth', 'user')
>>> loading.get_model('custom_auth', 'user', only_installed=False)
  > api.models.User
