22872	Backwards incompatible change: Can't proxy User model: RuntimeError: App registry isn't ready yet.	Jon Dufresne	nobody	"My application creates proxies of the user model to add custom methods that are useful in certain contexts. There is an attempt to do this in a `AUTH_USER_MODEL` agnostic way. This fails with the latest beta version of 1.7.

Starting from a fresh install and project I created the following files in directory `myapp`.

`myapp/models.py`

{{{
from django.contrib.auth import get_user_model


class MyUser(get_user_model()):
    def my_method(self):
        return 'foo'

    class Meta:
        proxy = True
}}}

`myapp/tests.py`

{{{
from django.test import TestCase
from myapp.models import MyUser


class MyTestCase(TestCase):
    def test_my_user(self):
        user = MyUser()
        self.assertTrue(user)
}}}

If there is a better (or forward compatible) way proxy an unknown `User` model, I'd be happy to hear about it."	Cleanup/optimization	closed	Documentation	1.7	Normal	wontfix		app-loading	Accepted	0	0	0	0	0	0
