密码格式无效或未知的哈希算法

我网站上的一位用户最近在尝试登录时成功触发了此回溯。在 Django Admin 中，他的密码为Invalid password format or unknown hashing algorithm.

我不知道是什么原因造成的。到目前为止，这只是一个孤立的案例，我和其他用户已成功注册并登录该网站。

追溯

不要将密码设置为空字符串，而是使用以下命令将密码设置为不可用set_unusable_password()的方法User model https://docs.djangoproject.com/en/dev/topics/auth/#django.contrib.auth.models.User.set_unusable_password:

user.set_unusable_password()
