我有一个

模板，其中包含以下内容：

<form method="post" action="{% url 'django.contrib.auth.views.login' %}">

如果我按如下方式更改url标记，那么我将得到另一个回溯

有人能告诉我哪里出了问题吗？

你试过了吗：

<form method="post" action="{% url '/accounts/login/' %}">

您应该使用URL模式名称，而不是点式python路径

您尚未显示如何在URL中包含登录视图，因此我们只能猜测正确的名称，但它可能是

“login”

<form method="post" action="{% url 'login' %}">

我已经尝试过了，但得到了“找不到“/accounts/login/”的相反结果。/accounts/login/”不是有效的视图函数或模式名称。“谢谢，这解决了问题：）
