Getting a problem in django url when I am at url ...abc/pqr and I click on xyz than It is not getting to the ...xyz but ...abc/xyz
我的大学管理系统项目出现问题。我试图在我的项目中添加作业提交功能。其中，当学生点击老师创建的作业时，他将进入一个页面，该页面是：提交作业页面，或者如果他已经提交了该作业，则更新或仅显示相关信息。

我有类似类型的 url 用于更新学生详细信息，它不会抛出这样的错误 url。
在你的base.html
当您为 <a> 标签设置 href 时，请确保它是
href="{% url 'some-url-name' %}"
比如你写的
href="studentattendancereport"
这只会将其附加到您当前的 url
你必须为
做出正确的选择
href="studentattendancereport" ---> href="{% url 'studentattendancereport' %}"
href="marksreportstudent" ---> href="{% url 'marksreportstudent' %}"
href="assignment" ---> href="{% url 'assignment' %}"
href="applyforleavestudent" ---> href="{% url 'applyforleavestudent' %}"
您可以参考here了解更多django's url template tag
