我一直在寻找答案，但仍然无法找到适用于我的解决方案。
我是Django的新手。我写了一个网络应用程序，它基本上是一个博客，其中作者将拥有他们的网站，并在每篇文章下将有一个评论部分。我希望在创建之后，超级用户将自动成为作者之一。用户名字段不是必需的，因为作者将被他们的名字和姓氏识别。这就是我需要他们只使用电子邮件登录的原因。
我使用的Django版本是2.0，我尝试尽可能使用CBV（基于类的视图）。
在用户名不相关且在登录页面中仅使用电子邮件和密码后，我无法在两种情况下登录： - 用户在网站登录页面上注册 - 由于管理员通过控制台命令在管理员登录页面上创建了超级用户
这是一个实际的例子。
删除整个数据库并在网页上注册常规用户并在终端中注册超级用户后，它们将正确保存在数据库中。用户名字段为空。
id username email first_name last_name is_active is_staff is_superuser
---------- ---------- ------------------- ---------- ---------- ---------- ---------- ------------
1 johnsmith@gmail.com John Smith 1 0 0
2 mysu@gmail.com Mysuper Myuser 1 1 1
但是我不能以网站上的普通用户或管理页面中的超级用户身份登录。
对于某些设置中后端配置的问题。我按照docs中的内容进行了操作，因此我的设置文件的部分是：
settings.py
