我几乎完成了 Udemy 上的 Web 开发类(class)，但在最后一步绊倒了。我真的希望有人能够帮助我，因为这似乎是我正在努力解决的一件非常简单的事情。
问题似乎出在用户单击“登录”链接时触发的 HttpResponseRedirect(reverse('index'))。
非常感谢!
错误在 http://127.0.0.1:8000/basic_app/user_login/ 触发
NoReverseMatch at /basic_app/user_login/
Reverse for 'basic_app/user_login' not found. 'basic_app/user_login' is not a valid view function or pattern name.

最佳答案
您在 templates/basic_app/login.html 表单的 action 属性中有错字。将 basic_app/user_login 更改为 basic_app:user_login
<form action="{% url 'basic_app:user_login' %}" method="post">
