Django 1.8 LookupError : Model not registered AUTH_USER_MODEL

Question

Django 1.8 and Python 3.4

I'm using a custom User model called UploaderClient in my app called authenticateclients . When I run check or makemigrations or migrate I get a LookupError: Model 'authenticateclients.UploaderClient' not registered. error. Please help.

In settings.py I have defined AUTH_USER_MODEL as authenticateclients.UploaderClient

authenticateclients/models.py

    from django.db import models
    from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

    # Create your models here.

   class UploaderClientManager(BaseUserManager):
       def create_user(self, accountname, password=None, **kwargs):
           if not accountname:
               raise ValueError('Users must have a valid accountname.')

           if not kwargs.get('email'):
               raise ValueError('Users must have a valid email.')

           if not kwargs.get('company_name'):
               raise ValueError('Users must have a valid company name.')

           account = self.model(
               accountname=self.normalize_accountname(accountname),email=kwargs.get('email'), company_name=kwargs.get('company_name')
           )

           account.set_password(password)
           account.save()

           return account

       def create_superuser(self, accountname, password, **kwargs):
           account = self.create_user(accountname, password, **kwargs)

           account.is_admin = True
           account.save()

           return account


   class UploaderClient(AbstractBaseUser):
       email = models.EmailField()
       accountname = models.CharField(max_length=100, unique=True)
       company_name = models.CharField(max_length=100)
       vuforiadb_name = models.CharField(max_length=100, blank=True)

       is_admin = models.BooleanField(default=False)

       created_at = models.DateTimeField(auto_now_add=True)
       updated_at = models.DateTimeField(auto_now=True)

       objects = UploaderClientManager()

       USERNAME_FIELD = 'accountname'
       REQUIRED_FIELDS = ['email','company_name']

       def __unicode__(self):
           return self.accountname

       def get_company_name(self):
           return self.company_name

       def get_vuforiadb_name(self):
           return self.vuforiadb_name

LookupError: Model 'authenticateclients.UploaderClient' not registered.

So what I did is comment the line

AUTH_USER_MODEL = 'authenticateclients.UploaderClient'

and run makemigrations and migrate. The migrations were applied. Then on uncommenting the above line and trying check or makemigrations or migrate I'm still getting the same error.

Please help with the error. If it is not possible to fix, can I proceed with my Project by commenting out the line or will the authentication not work if I leave out the line..

Answer 1

For this specific problem, part of the problem is already pointed out by @danihp. You need to put the app with your custom model before "cms" in your INSTALLED_APPS.

INSTALLED_APPS = {
    'your_custom_app',
    '...',
    'cms',
}
