django : cannot import name patterns?

在 mysite 站点下，创建 polls ,并注册了 polls。

#python manage.py runserver 0.0.0.0:80

vim  polls/urls.py

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

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

vim polls/views.py
    from django.http import HttpResponse

    def index(request):
        return HttpResponse("hello,you are the poll index.")
     

在mysite下, vim urls.py
    from django.conf.urls.defaults 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)),
    )


打开

ImportError at /polls

cannot import name patterns

解决办法：vim polls/urls.py

     将     from django.conf.urls import patterns, url
     改为  from django.conf.urls.defaults import *

即可出现：hello,you are the poll index.
