子模型中的 Django 用户模型

Question

在我当前的项目中，我正在替换默认的 django 用户模型。随着模型数量开始增长，我决定将实现拆分为几个文件夹，但现在 django 找不到我的用户模型。

我有这个，它有效：

djutils
    models.py
        UserManager
        User

我改成这个了，不行了

djutils
    models
        __init__.py
            from djutils.models.user import UserManager, User
        user.py
            UserManager
            User

不应该还是导入模型吗？我明白了：

CommandError: One or more models did not validate:
auth.user: Model has been swapped out for 'djutils.User' which has not been installed or is abstract.

我的 settings.py 中有这个

AUTH_USER_MODEL = 'djutils.User'

（注意第一个案例有效）

请指教！ 问候

                # A string describing the name of the field on the User model that is used as the unique identifier
                USERNAME_FIELD = 'email'

                # A list of the field names that must be provided when creating a user via the createsuperuser management command
                REQUIRED_FIELDS = ['first_name', 'last_name', 'password']

                # Fields that are not returned by get_public
                PRIVATE = ['is_active', 'is_superuser', 'is_staff', 'last_login', 'groups', 'user_permissions', 'password', 'id']

                # Model manager
                objects = UserManager()

                class Meta:
                    swappable = 'AUTH_USER_MODEL'
                    permissions = ()

                def send_mail(self, request, subject, body, context={}):
                    mail.send_mail(request, subject, body, [self.email], context)

                def send_confirmation_email(self, request, context={}):
                    self.send_mail(request, settings.CONFIRMATION_SUBJECT, settings.CONFIRMATION_TEMPLATE, dict(context, **{
                        'redirect': request.build_absolute_uri(settings.CONFIRMATION_REDIRECT_URL)
                    }))

在您的 User 模型的 Meta 类中设置 app_label = 'djutils'。
