Django网站上找不到404页面？ [英] Page not found 404 on Django site?

问题描述

我正在Django网站上的教程中创建一个简单的投票应用程序。但是，Django无法解析//127.0.0.1:8000/polls，即使我在mySite / urls.py中定义了正则表达式。我在一个virtualenv这样做，最新的Django（1.7）安装。来自django.conf的

mySite / urls.py：

  url import pattern，include，url 
 from django.contrib import admin 
 
 urlpatterns = patterns（''，
 url（r'^ admin /'，include（admin.site 。
 
 
 
 
 
 
 
 
 
 $ > 
 
 
 mySite / polls / urls.py：
  from django.conf.urls导入模式，url 
从投票导入视图
 
 urlpatterns = patterns（''，
 url（r'^ $'，views.index，name ='index'）， 
）
  
 mySite / polls / views.py：
 
从django.shortcuts导入render 
从django.http导入HttpResponse 
 def索引（请求）：
返回HttpResponse（你好，世界，你在民意测验索引。）
  

mySite / settings.py： / p>

  ... 
 INSTALLED_APPS =（
'django.contrib.admin'，
' django.contrib.auth ，
'django.contrib.contenttypes'，
'django.contrib.sessions'，
'django.contrib.messages'，
'django.contrib.staticfiles'，
'polls'，
）
 .... 
 ROOT_URLCONF ='mySite.urls'
  

我收到的错误：

 使用mySite.urls中定义的URLconf， Django按照以下顺序尝试了这些URL模式：^ admin / 
当前的URL，polls，与之不匹配。 
  

解决方案

我也有同样的问题。

事实证明，由于名为mysite的多个目录，我感到困惑。

我在根mysite目录（包含manage.py）中错误地创建了一个urls.py文件，然后粘贴在网站的代码中。要修正它，我删除了这个文件，进入mysite / mysite目录（其中包含settings.py），修改了现有的urls.py文件，并用代码代替代码。

简而言之，确保您的urls.py文件位于正确的目录。

I'm following the tutorial on Django's site to create a simple poll app. However, Django is unable to resolve "//127.0.0.1:8000/polls" , even though I've defined the regex in mySite/urls.py. I'm doing this in a virtualenv, with the latest Django (1.7) installed.

mySite/urls.py:

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

urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^polls/', include('polls.urls')),
)

mySite/polls/urls.py:

from django.conf.urls import patterns, url
from polls import views

urlpatterns = patterns('',
url(r'^$', views.index, name='index'), 
)

mySite/polls/views.py:

from django.shortcuts import render
from django.http import HttpResponse
def index(request):
    return HttpResponse("Hello, world. You're at the polls index.")

mySite/settings.py:

 ...
 INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'polls',
 ) 
  ....
 ROOT_URLCONF = 'mySite.urls'

The error I'm getting:

Using the URLconf defined in mySite.urls, Django tried these URL patterns, in this order: ^admin/  
The current URL, polls, didn't match any of these.

解决方案

I had the same problem.

It turns out I was confused because of the multiple directories named "mysite".

I wrongly created a urls.py file in the root "mysite" directory (which contains "manage.py"), then pasted in the code from the website.

To correct it I deleted this file, went into the mysite/mysite directory (which contains "settings.py"), modified the existing "urls.py" file, and replaced the code with the tutorial code.

In a nutshell, make sure your urls.py file is in the right directory.
