------------------------------------------+-----------------------------
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:
{{{
Traceback (most recent call last):
File "./manage.py", line 22, in <module>
execute_from_command_line(sys.argv)

line 158, in __new__
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,
