我安装了名为注册的 Django 应用程序。我设置了模板，添加到 url 和查看文件，一切都很正常。现在我在注销后重新登录系统时遇到了问题（以前从未发生过）我从浏览器中清除了 cookie 和浏览历史记录（我尝试了多个以查看是否是问题所在）并进入“/registration/login /" 然后我输入信息就可以登录了。我单击注销按钮，它会将我注销，一切正常。问题是当我第二次登录时，我转到“/registration/login/”并在表单中输入我的信息并提交并获取

现在通常这些错误会在“Reverse for '' with”中给出一个名称以及一个行号，它通常是一个 URL 问题。我不明白的是，如果我可以访问此 URL，为什么表单不会发布到它。提前感谢您提供的任何提示或提示，让我知道您需要查看的内容，我会上传。

请注意，我尝试更改 {{ app_path }} 但它没有改变任何东西我仍然遇到相同的错误
