我正在尝试通过电子邮件授权创建用户模型（使用Django 1.7 Python 3.4）。我用admin类创建了自定义用户模型。但是当我在django管理面板中尝试编辑用户实例时，我收到一个错误：
/ admin / accounts / account / 1 /的AttributeError 'AccountForm'对象没有属性'get'
我可以通过django model API无问题地修改用户数据，只有管理面板才会出现问题。 Traceback说，电子邮件领域有些不对劲，但我不知道究竟是什么。

我从文档中拿了一个例子： https://docs.djangoproject.com/en/1.7/topics/auth/customizing/ 它突然开始工作了。 如果所有尝试都没有帮助 - 请参阅说明!!!
