AbstractUser Django full example

Question

I am new to Django and I have been trying this for weeks, but could not find a way to solve this problem.

I want to store additional information like user mobile number,

Answer 1

Inlines forms assume that you have a Generic ForeignKey on your model, in this case, the UserProfileAdmin expect a Generic ForeignKey of the UserProfile, that does not exists. Try to do a regular Model Admin, like:

class UserProfileAdmin(admin.ModelAdmin):
    can_delete = False
    verbose_name_plural = 'userprofile'

admin.site.register(UserProfile, UserProfileAdmin)

Answer 2

You have confused yourself a bit here. The idea of subclassing AbstractUser - and defining AUTH_USER_MODEL as your subclass - is that the new model completely replaces auth.models.User. You shouldn't be importing the original User at all, and you certainly should be calling User.objects.create_user(): your new model's manager now has its own create_user method.

Because of this, there's no reason to muck about with inline admins. Your UserProfile should be registered in the admin using the existing django.contrib.auth.admin.UserAdmin class.
