我的项目名为 homefood，当我运行服务器时出现此错误。任何人都知道如何修复此错误。

Page not found (404)

Request Method: GET

Request URL:    http://127.0.0.1:8000/

Using the URLconf defined in homefood.urls, Django tried these URL patterns, in this order:

^foodPosts/

^admin/

The current URL, , didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

我的 settings.py 文件看起来像这样......

我的 homefood 文件夹中的 urls.py 是

from django.conf.urls import patterns, include, url




from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
   # Examples:
  # url(r'^$', 'homefood.views.home', name='home'),
  # url(r'^blog/', include('blog.urls')),


  url(r'^foodPosts/',include('foodPosts.urls')),
  url(r'^admin/', include(admin.site.urls)),


 )

我认为我的问题要么在我的 urls.py 中，要么在我的 settings.py 中，但我不确定。任何帮助将不胜感激。谢谢。

最佳答案

您收到 404 是因为您还没有为 http://127.0.0.1:8000/ 定义 url 模式。

您应该能够在 http://127.0.0.1:8000/admin/ 查看管理站点，在 http://127.0.0.1:8000/查看您的美食帖子foodPosts/.

要为主页添加 url 模式，请取消注释 urls.py 中的以下条目，并将 homefood.views.home 替换为您要使用的 View 的路径。

url(r'^$', 'homefood.views.home', name='home'),
