Python &引用；无法使用提供的凭据登录。”；尝试登录我的用户时

我在尝试登录注册用户时遇到此错误。我读了很多关于人们问同样问题的答案，但是没有一个能解决我的问题，所以我对正在发生的事情感到困惑。我在我的设置中添加了一些东西，比如一些评论，并改变了一些东西，到目前为止，我写的这些东西都没有用。也许多看几眼会有帮助。多谢各位

我将在这里显示我的序列化程序：

user = get_user_model()

如果您不将请求传递给

身份验证
，会发生什么情况？只有用户名和密码。还有，你检查过外壳了吗？获取用户并执行
用户操作。检查\u password（）
@gdef\u。感谢您的评论。在shell中尝试User.objects.get（）时，会出现以下错误：AttributeError:Manager不可用；'身份验证用户“”已被替换为后端用户“”。我不确定这是否有关联。另外，如果我取消了身份验证，我会得到以下错误：字段“id”需要一个数字，但得到了。@gdef_u我可以解决管理器问题，但我仍然只能得到我的超级用户，而不能得到其他用户。
