新手Python和Django编码器

我正在尝试应用一些注册插件所需的迁移文件（django-registration-redux == 1.3）。但是，当我运行 python manage.py migration 命令时，出现以下错误

Traceback (most recent call last):
  File "manage.py", line 15, in <module>
    execute_from_command_line(sys.argv)

    user = models.OneToOneField(UserModelString(), verbose_name=_('user'))
TypeError: __init__() missing 1 required positional argument: 'on_delete'

不确定如何解决此错误或完全理解其含义。

快速浏览django-registration-redux文档（https://django-registration-redux.readthedocs.io/en/latest/quickstart.html）之后，我建议将其更新至该软件包的最新版本，即2.5。我大多数时候都发现这种类型的错误问题与django设置有关，即是否添加了正确的中间件，INSTALLED_APPS等，希望对我有所帮助。
