I'm trying to use custom User model. Created app named "cw_auth", created "AppUser" model in it, added module to INSTALLED_APPS and added 
AUTH_USER_MODEL = 'cw_auth.AppUser'
to settings.py file. But when I'm trying to perform
./manage.py makemigrations cw_auth
I'm getting errors

cw_auth/models.py code bellow:

def get_full_name(self):

@property

return self.role == 1 or self.role == 2

Without AUTH_USER_MODEL migrations going well. Please help.

Have you tried cw_auth.models.AppUser as the value for AUTH_USER_MODEL?

Did you add "cw_auth" to your "INSTALED_APPS"?
