Proxy for User model referenced as AUTH_USER_MODEL

[Nicolas Pantel]

As ​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:

Traceback (most recent call last):
  File "./manage.py", line 22, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python3.6/dist-packages/django/core/management/__init__.py", line 363, in execute_from_command_line

    raise TypeError("%s cannot proxy the swapped model '%s'." % (name, base_meta.swapped))
TypeError: MyUser cannot proxy the swapped model 'proxy_user.MyUser'.

Is it a bug or a misunderstanding?

Thanks,

​As documented, the behavior seems expected. Your ​post on django-users, is the correct place to ask "is it a bug?" questions (see TicketClosingReasons/UseSupportChannels).
