Django1.0修改后内容

今天在配置django 1.02 在激活Admin 時費了不少事，google了一下，原來是django 配置有變化。






可參考Django Step by Step 1.0.2

 The new tutorial is not finished yet.


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),
)
