【问题描述】：
我在大学管理系统项目中遇到问题。我试图在我的项目中添加作业提交功能。当学生点击教师创建的作业时，它会引导他进入一个页面，该页面是：作业提交页面，或者如果他已经提交了该作业，则更新或仅显示相关信息。
项目的urls.py文件
from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('cmsapp.urls')),
]
urlpatterns+= static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
用于 cmsapp 的 urls.py。
urlpatterns = [...
path('studentattendancereport', studentviews.student_attendance_report, name='studentattendancereport'),
path('fetchstudentattendance', studentviews.fetch_student_attendance, name='fetchstudentattendance'),
path('applyforleavestudent', studentviews.applyforleave, name='applyforleavestudent'),
path('marksreportstudent', studentviews.marksreportstudent, name='marksreportstudent'),
path('assignment', studentviews.assignments, name='assignment'),
path('assignmentupload/<int:id>', studentviews.assignment_upload, name='assignmentupload'),
]

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。
【问题讨论】：
-
请分享主 urls 文件，哪个视图/模板有问题？
-
我不知道问题出在哪里，但问题是这样的，当我进入 assignment_upload 视图时，浏览器 url 中的 url 变为 preurl/assignment_upload/id_of_assignment 之后当我点击在其他链接上，而不是转到该链接，但在浏览器 url 中显示 preurl/assignment_upload/link_that_i_click_on 但是它应该是 preurl/link_that_i_click_on，我在应用程序 urls.py 文件上方添加了项目主 urls.py
-
我没听懂你的意思，你要准确，所以我们任何人都可以提供帮助。
-
先生，我认为问题出在 assignment_upload 视图以及模板 assignment_report.html 和 assignment_upload.html，对不起先生，我无法说出确切的情况，我是新手，所以我不知道确切的术语。
-
当我在 assignment_upload 视图中时，浏览器显示的 url 像 127.0.0.1:8000/assignmentupload/1 1 在这里是 assignment id ，当我从这里点击链接 applyforleavestudent 时，该链接位于 base.html 中，该链接由 assignment_report 扩展。 html 比它去127.0.0.1:8000/assignmentupload/applyforleavestudent 但它应该去 url 127.0.0.1:8000/applyforleavestudent
