urls.py
以前的这么写：
from django.conf.urls.defaults import *
urlpatterns = patterns('',
    (r'^admin/', include('django.contrib.admin.urls'),
)
Django1.0改成：
from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    (r'^admin/(.*)', admin.site.root),
)
