thank you for this article.

Unfortunately i’m having an issue; i’m able to create a CustomUser through the admin interface (like described in comment #8).
But the CustomUsers will appears in admin/auth/user/ (without the custom fields) and nothing will appear in admin/myapp/customuser/.

Is there a clean way to fully add/list/edit extended users through the admin interface or must i make my own admin interface?

When I create a foreign key to the new CustomUser class and specify “to_field = ‘username’” it works fine with validation and saving but the moment you try and do a order_by on the new model which references a field in the User model it fails with customuser__username field not found.

Example:

class CustomUser(User):
    ......

class X(models.Model):
    added_by = models.ForeignKey(CustomUser, to_field = 'username')

X.objects.all().order_by('added_by__last_name)

I use auto complete fields in my forms that use the username as a value so if I don’t specify to_field in my model the validation will fail as it’s expecting the CustomUser.id.

Maybe there is a way to tell the ModelForm to validate using the username?

delimiter //
create trigger trigger_custom_user
after insert on auth_user
for each row
begin
insert into myapp_customuser (user_ptr_id) values(NEW.id);
//

It’s at the sql level and therefore not ideal, but it works.

If the 403 CSRF error is the problem you are having I suggest you remove django.contrib.csrf.middleware.CsrfMiddleware from your MIDDLEWARE_CLASSES and find out what the problem really is.

Yet I failed to apply this method successfully.
First, the changes I’ve made:

— Added to settings.py bottom:

AUTHENTICATION_BACKENDS = (
    'website.auth_backends.CustomUserModelBackend',
)

CUSTOM_USER_MODEL = 'profiles.CustomUser'

— Added to urls.py top:

from django.conf.urls.defaults import *
from django.contrib.auth.models import User
from django.contrib import admin
admin.autodiscover()
admin.site.unregister(User)

— settings.py INSTALLED_APPS:

(    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'fullhistory',
    'website.courses',
    'website.profiles' )

— profiles/models.py:

from django.db import models
from django.contrib.auth.models import User, UserManager
from fullhistory import register_model #this has nothing to do with users, it just logs every write to the database
from website.courses.models import Course #website is my Django project folder obviously

class CustomUser(User):
    cellphone = models.CharField(max_length=20)
    courses = models.ForeignKey(Course, null=True, blank=True)
    updatedat = models.DateTimeField(null=True, blank=True)

    objects = UserManager()

I’ve tried with and without AUTH_PROFILE_MODULE = ‘profiles.CustomUser’, but with no luck.

Any suggestions?

Forgot to add, it gives me 403 CSRF.
