django AbstractUser model 'str' object has no attribute '_meta'

Question

I can not register a custom User model in the admin.py. No admin.py , all works fine

Why do the customUser? I not know what this is problems. I did everything according to the documentation

models.py

from django.db import models
from django.contrib.auth.models import AbstractUser
from django.utils.translation import ugettext_lazy as _

AbstractUser._meta.get_field('email')._unique = True
AbstractUser._meta.get_field('email').blank = False


class User(AbstractUser):
    is_agency = models.BooleanField(_('agency status'), default=False)
    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']

    def get_is_agency(self):
        return self.is_agency

admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from settings import AUTH_USER_MODEL as CustomUser

admin.site.register(CustomUser, UserAdmin)

This line is importing the string name of your user model, not the actual class.

from settings import AUTH_USER_MODEL as CustomUser

You should import the class from your models.py file.

from <app_name>.models import User as CustomUser

I can think of two possible reasons for this:

1) If you use this admin.site.register(classname) (with single/double quotes) it generates an error

Instead use this:

admin.site.register(**classname**)  # (without single/double quotes)

2) If you forget to import class in admin.py, the same error is generated.

To keep the application independent you should use:

from django.contrib.auth import get_user_model

CustomUser = get_user_model()

You can check what it does here
