Django 应用程序上的关于页面显示找不到页面

Question

尝试使用 Sublime 文本编辑器在 Django 项目上运行 about 页面。每次我刷新浏览器时，该项目都会显示未找到页面。我已经尝试过我遇到的所有方法。 我的项目结构在 Sublime 文本编辑器上看起来像这样。

-DjangoProjects
   -myfirstproject
   -myfirstproject-root
    /*-pyache
    /*-init.py
    /*-asgi.py
    /*-settings.py
    /*-urls.py
    /*-views.py
    /*-wsgi.py
    -db.sqlite3
    /*-manage.py

     -Urls.py

      from.django contrib import admin
      from django.urls import path
      from . import views

      urlpatterns = [
      path('admin/', admin.site.urls)
      path('about/', views.urls)
      ]

我希望该项目能够显示关于页面的内容。不返回 404 错误响应。

        -views.py

        from django.http import HttpResponse


        def index(request):
        return HttpResponse("This is about page.")

在您的主要

urls.py

中，您应该致电

views.index

。

旧

urls.py

：

from.django contrib import admin
from django.urls import path
from . import views

urlpatterns = [
 path('admin/', admin.site.urls)
 path('about/', views.urls) 
]

更新

urls.py

：

from.django contrib import admin
from django.urls import path
from . import views

urlpatterns = [
 path('admin/', admin.site.urls)
 path('about/', views.index)  # Changes Done Here
]
