29328	Proxy for User model referenced as AUTH_USER_MODEL	Nicolas Pantel	nobody	"As [https://docs.djangoproject.com/en/2.0/topics/auth/customizing/#extending-the-existing-user-model stated in the doc], needing to add some methods to User model, I tried to make a 'proxy' model.

settings.py:

{{{
AUTH_USER_MODEL = ""myapp.MyMuser""
}}}

myapp/models.py:

{{{
from django.contrib.auth.models import User

class MyUser(User):
    class Meta:
        proxy = True
}}}

But on server launch, the following error is triggered:

{{{

Is it a bug or a misunderstanding?
