django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'app.User' th-CodePudding

this question has been asked a lot of times but I am asking it because I still cannot find any workable solution. I am trying to create a custom user model using AbstractBaseUser inside the myapp app and I have written the app name inside INSTALLED_APPS and the command AUTH_USER_MODEL = 'myapp.User' inside settings.py. The command python manage.py makemigrations --dry-run works perfectly without any errors when my custom user model is stored within the default model file location at backend/myapp/models.py but I want to rename and move this file to the directory backend/myapp/models/user.py and have it stored along with other models. Whenever I try and move or rename the backend/myapp/models.py file which has my custom user model, Django returns the django.core.exceptions.ImproperlyConfigured error. Need help. Thanks

backend/myapp/models.py:

from django.db import models
from django.contrib.auth.models import AbstractBaseUser

class User(AbstractBaseUser):
    id = models.CharField(max_length=15, null=False, blank=False, primary_key=True, unique=True)

    USERNAME_FIELD = "id"

CodePudding user response：

In settings.py Add myapp in INSTALLED_APPS

INSTALLED_APPS = [
    ...,
    'myapp',
]

I User model add app_label = 'myapp' like

class User(AbstractBaseUser):
    id = models.CharField(max_length=15, null=False, blank=False, primary_key=True, unique=True)

    USERNAME_FIELD = "id"

    class Meta:
        app_label = 'myapp'

If you want to move the model in a separate file. The directory structure should like

myapp
   models
       __init__.py
       user.py

Put User model code in user.py Then import User model in __init__.py

from myapp.models.user import User
__all__ = ["User"]
