这是我在 Django 应用程序中面临的一个奇怪问题。

配置 ：

我已将 create_superuser 覆盖为：

def create_superuser(self, email, is_staff, password):
    user = self.model(
        email=email,
        is_staff=True,
        is_active=True,
    )
    user.set_password(password)
    user.save(using=self._db)
    return user

我能够成功创建超级用户，但无法登录管理页面。以下是我的回溯：

这是非常不寻常的（我理解错误的含义）并且我无法理解是什么导致了它或如何修复它。

还有其他变化吗？我无法复制此问题，如果我将create_superuser功能更改为您发布的功能，我什至无法创建超级用户。它只是失败了，因为用户名仍在传入，这是出乎意料的。

但是，如果您确实碰巧让它运行，那么看起来password参数可能None是导致set_password函数set_unusable_password根据文档调用。

但是，要深入了解问题实际上是什么，则需要更多信息。
