Django 管理員：自定義用戶 model 在 app 部分而不是 auth 部分

Question

如問題 36046698 一樣，我在models.py中定義了一個 CustomUser model 。

我希望它出現在 Django Admin 的Authentication & Authorization部分。

我嘗試按照建議添加 app_label = 'auth' ，即

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

當我這樣做時，我的應用程序將無法啟動，並且錯誤如下：

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)

    raise LookupError(

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'myapp.CustomUser' that has not been installed

在settings.py ，我有

AUTH_USER_MODEL = 'myapp.CustomUser'

如果我注釋掉該行，服務器將啟動，但頁面加載失敗：

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

這似乎與問題 62394664相同的崩潰。

好像您忘記遷移數據庫了。 試試這個命令python manage.py makemigrations python manage.py migrate
