Error analysis:

Return page in vews. py: Return httpresponseredirect (reverse ('user _ Index '))

The configuration in URLs. py is as follows:

 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:  
 )

Error because user_index cannot be mapped to the URL http: // 127.0.0.1: 8000/index/
That is, there is a problem with URL ing.

 

Solution:

Solution 1: directly modify return httpresponseredirect ('/index /')
