错误分析：

　　vews.py 中的返回页面：return HttpResponseRedirect(reverse('user_index'))

urls.py 中的配置如：

from django.conf.urls.defaults import patterns, url
import os
import settings
#from django.views.generic import ListView,DetailView
#from users.models import  UserInfo
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
    url(r'^user/register/$','UCenter.users.views.register',name='user_register'),
#url(r'^index/$','UCenter.users.views.index',name='user_index'),
    url(r'^index/$','UCenter.users.views.index',name='user_index'),
# Examples:
)
