python - Django Admin：应用程序部分而不是身份验证部分中的自定义用户模型

问题描述

与问题 36046698 一样，我在models.py.

我希望它出现在Authentication & AuthorizationDjango Admin 的部分中。

我尝试按照建议添加 app_label = 'auth' ，即

class CustomUser(AbstractUser):
    class Meta:
        app_label = 'auth'

当我这样做时，我的应用程序将无法启动，并且错误如下：

Traceback (most recent call last):
  File "/Users/paul/myapp/.direnv/python-3.8.5/lib/python3.8/site-packages/django/apps/config.py", line 178, in get_model
    return self.models[model_name.lower()]
KeyError: 'customuser'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/Users/paul/myapp/.direnv/python-3.8.5/lib/python3.8/site-packages/django/contrib/auth/__init__.py", line 157, in get_user_model
    return django_apps.get_model(settings.AUTH_USER_MODEL, require_ready=False)
  File "/Users/paul/myapp/.direnv/python-3.8.5/lib/python3.8/site-packages/django/apps/registry.py", line 211, in get_model

  File "/Users/paul/myapp/.direnv/python-3.8.5/lib/python3.8/site-packages/django/apps/config.py", line 180, in get_model
    raise LookupError(
LookupError: App 'myapp' doesn't have a 'CustomUser' model.

  File "/Users/paul/myapp/.direnv/python-3.8.5/lib/python3.8/site-packages/django/contrib/auth/__init__.py", line 161, in get_user_model
    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'myapp.CustomUser' that has not been installed

中settings.py，我有

AUTH_USER_MODEL = 'myapp.CustomUser'

如果我注释掉该行，服务器将启动，但页面加载失败：

ValueError: Cannot create form field for 'user' yet, because its related model
'CustomUser' has not been loaded yet

这似乎与问题 62394664相同的崩溃。

解决方案

好像您忘记迁移数据库了。试试这个命令 python manage.py makemigrations python manage.py migrate
