我有一个project 跟目录的root url conf 设置内容为:

----------------------------------------------------------

from django.conf.urls import patterns, include, url
import funnytest
urlpatterns = patterns(
url(r'^funnytest/', include('funnytest.urls')),
url(r'^helloworld/', funnytest.views.hello),
)

-----------------------------------------------------------

其中funnytest是其中一个app，funnytest 目录下设置了一个Urls, 内容为:
------------------

from django.conf.urls import patterns, include, url
from views import *
urlpatterns = patterns(
url(r'^hello/$', hello),
)

-------------------

我访问 localhost/funnytest/hello/ 会报错，表示urls 中没有匹配的配置
但是访问localhost/helloworld 是可以访问到view hello 的

为什么呢，应该如何配置～
