Question

我的项目名为homefood，当我运行服务器时，我收到此错误。任何人都有任何线索如何解决此错误。

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......

import dj_database_url
"""

BASE_DIR = os.path.dirname(os.path.dirname(__file__))

)                                           #static asset configuration

和我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)),


 )

我认为我的问题出在我的urls.py或者我的settings.py中，但我不确定。任何帮助将不胜感激。感谢。

Answer 1

您正在获取404，因为您还没有为http://127.0.0.1:8000/定义网址模式。

您应该可以在http://127.0.0.1:8000/admin/查看管理网站，在http://127.0.0.1:8000/foodPosts/查看您的食物信息。

要为首页添加网址格式，请在urls.py中取消注释以下条目，并将homefood.views.home替换为您要使用的视图的路径。

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

Answer 2

基本上的答案是在项目 urls.py 文件中添加一个条目作为空白示例：

path('', include('MYAPP.urls')),

并在应用程序 urls.py 中添加

url('MYAPP', views.index),

确保在 settings.py 中包含您的应用程序，并确保在应用程序 urls.py 中导入视图

Answer 3

我也遇到此错误，解决方案是将相关应用的name=文件中urls.py参数的双引号更改为单引号！

path('register', views.register, name='register')

Answer 4

与 OP 不直接相关，但可能对其他人有用：

在我不小心从 path() 路由 (django 3.2) 中删除了尾部斜杠后，我的管理页面都变成了 404：

urlpatterns = [
    path('admin', admin.site.urls),  # trailing slash missing...
    path('', include('myapp.urls'))
]

通过恢复到 'admin/' 可以轻松解决此问题。
