无法设置设置在Django中{AUTH_USER_MODEL

如何解决无法设置设置在Django中{AUTH_USER_MODEL

以前，我无法为我的项目设置AUTH_USER_MODEL = 'apps.authuser.User'。我所有的应用程序都合并到一个文件夹中，并以apps命名。项目结构是这样的；

├── apps
│   ├── authuser/
│   │   ├── __init__.py
│   │   ├── apps.py
│   │   ├── models/
│   │   │   ├── __init__.py
│   │   │   └── user.py
│   │   ├── utils
│   │   │   ├── backends.py
│   │   │   └── __init__.py
│   ├── blog/
│   │   ├── __init__.py
│   │   ├── apps.py
│   │   └── models/
│   ├── product/
│   │   ├── __init__.py
│   │   └── apps.py
├── core/
│   ├── asgi.py
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── templates/
├── db.sqlite3
└── manage.py

1。 settings.py;

INSTALLED_APPS = [
    'django.contrib.admin','django.contrib.auth',....

    # major apps
    'apps.authuser','apps.blog','apps.product',]

# Custom Auth User Model
AUTH_USER_MODEL = 'apps.authuser.User'
AUTHENTICATION_BACKENDS = [
    'django.contrib.auth.backends.ModelBackend','apps.authuser.utils.backends.CustomAuthBackend'
]

2。 apps/authuser/apps.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.apps import AppConfig
from django.utils.translation import ugettext_lazy as _


class AuthUserConfig(AppConfig):
    name = 'apps.authuser'
    verbose_name = _('App Auth User')

3。 apps/authuser/__init__.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

default_app_config = 'apps.authuser.apps.AuthUserConfig'

4。 apps/authuser/models/__init__.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

# to custom the Auth User Model
# you need to import that model into this __init__.py file
# because we use the folder to manage it models.py
from .user import User

5。 apps/authuser/models/user.py;

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models
from django.urls import reverse
from django.conf import settings
from django.contrib.auth.models import AbstractUser
from django.utils.translation import ugettext_lazy as _


class User(AbstractUser):
    """
    extending from base `AbstractUser`
    to rewrite the `id` AutoField to `id` `BigAutoField`
    """
    id = models.BigAutoField(primary_key=True)

    @property
    def fullname(self):
        if hasattr(self,'profile') and self.profile:
            return self.profile.display_name
        return self.get_full_name() or self.username

我也尝试使用此解决方案https://stackoverflow.com/a/50179553/6396981，但仍然无法正常工作。

AttributeError: 'Settings' object has no attribute 'authuser_MODEL'

当我尝试在label = 'apps.authuser'中添加AuthUserConfig时，它向我显示了该错误；

ValueError: Invalid model reference 'apps.authuser.User_groups'.
String model references must be of the form 'app_label.ModelName'.

解决方法

如错误所述。您只需要应用名称和型号名称即可。

String model references must be of the form 'app_label.ModelName'.

因此auth模型的用户应该是

AUTH_USER_MODEL = 'authuser.User'
