我一直在尝试为普通用户和超级用户创建自定义用户注册表单，但我仍然无法以 superuser/admin 身份登录。我也无法注册任何用户，因为它没有连接到数据库。我按照本教程学习如何创建自定义用户 https://www.youtube.com/watch?v=5x97gGspzjY 并且我设法做到了。我只是无法以管理员身份登录，也无法注册任何用户。下一步具体是什么

据我所知，您的自定义模型 (CustomUser) 中没有 first_name 属性。这就是

AttributeError: 'CustomUser' object has no attribute 'first_name'

告诉你。

看看你的 CustomUser class。它正在定义 username、email 等，但它没有在任何地方定义 first_name。然而，您正试图在多种方法（即 get_full_name()、get_short_name().

中引用 first_name（未为 class/model 定义）

尝试定义它并查看错误是否仍然存在。

AttributeError: 'CustomUser' object has no attribute 'first_name'
