所以我在Django中为一个学校项目尝试自定义用户模型。我创建了一些继承自AbstractUser类的自定义字段，编写了一个自定义UserManager并在管理页面中注册了模型，最后从一个表单渲染了一个模板，该表单扩展了UserCreationForm并使用我的CustomUser作为模型（这一切似乎都很好，所有字段都在管理中可见，在添加和细节视图中也是可见的）。我也可以添加用户直接从管理页面，这是工作正常。
然而，当我提交表单时，我被重定向并在终端中获得[26/Jul/2023 13:10:40] "POST /register/ HTTP/1.1" 302 0，但用户没有保存在数据库中。
下面你可以找到我的文件。

在settings.py中，我包含了AUTH_USER_MODEL = 'accounts.CustomUser'
提交表单后，不会发生错误，但用户不会存储到数据库中。我们非常感谢您的帮助。
提前感谢！
