django 404问题

isohybrid

在学习django，按照tutorial一直弄，直到https://docs.djangoproject.com/en/1.1/intro/tutorial03/

就悲剧了，详细错误信息

就是当访问127.0.0.1:8000/polls的时候抛出异常

ViewDoesNotExist at /polls
Could not import polls.urls. View does not exist in module polls.

前前后后检查了很多次，google也未果，只好求助大家了

贴你的urls.py代码上来。

polls/urls.py

from django.conf.urls import patterns, url

from polls import views

urlpatterns = patterns('',
    # ex: /polls/
    url(r'^s', views.index, name='index'),
    # ex: /polls.5/
    url(r'^(?P<poll_id>\d+)/$', views.detail, name='detail'),
    # ex: /polls.5/results/
    url(r'^(?P<poll_id>\d+)/results/$', views.results, name='results'),
    # ex: /polls.5/vote/
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
    )

mysite/urls.py

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

from django.contrib import admin
admin.autodiscover()

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

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

HI，开始django用的是开发版1.7后来换成稳定版1.5的，照着重做了一次，还是卡在这额

Write your first view
Let’s write the first view. Open the file polls/views.py and put the following Python code in it:

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, world. You're at the poll index."
This is the simplest view possible in Django. To call the view, we need to map it to a URL - and for this we need a URLconf.

To create a URLconf in the polls directory, create a file called urls.py. Your app directory should now look like:

polls/
    __init__.py
    admin.py
    models.py
    tests.py
    urls.py
    views.py
In the polls/urls.py file include the following code:

from django.conf.urls import patterns, url

from polls import views

urlpatterns = patterns('',
    url(r'^$', views.index, name='index')
)
The next step is to point the root URLconf at the polls.urls module. In mysite/urls.py insert an include(), leaving you with:

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

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls')),
    url(r'^admin/', include(admin.site.urls)),
)
You have now wired an index view into the URLconf. Go to http://localhost:8000/polls/ in your browser, and you should see the text “Hello, world. You’re at the poll index.”, which you defined in the index view.

就这几步，搞不懂哪里出错了

127.0.0.1/admin         可以访问
127.0.0.1/polls            404

Page not found (404)
Request Method:        GET
Request URL:        http://127.0.0.1:8000/polls
Using the URLconf defined in Lili.urls, Django tried these URL patterns, in this order:
^polls/
^admin/
The current URL, polls, 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.

你的这个url引入不对把：url(r'^polls/', 'polls.urls'),   建议你先按照django的来，然后在自己修改。

我把官方的tutorial实现了下，放到github上，欢迎参考：https://github.com/the5fire/django_tutorial_demo

已解决，十分感谢LS的同志

哎，晕死了，我也是遇到了这个问题，为什么需要include('polls.urls',namespace="polls").更可气的是官方的文档里居然没有提及。走了很长时间弯路。

    官方文档没有提及，只能说你没看仔细。反正include的用法我就是看官方文档学的

话说，最后问题是如何解决的？
