hello,

i have a regular expression confusion error i cant work my app with together 2 and 3 line from my blog/urls if i work regardless that lines work fine

but i need together for my project.

my mysite/urls

url(r'^admin/', include(admin.site.urls)),
url(r'', include('blog.urls')),

The second line should probably be a r'^', rather than just an empty string.

 

my blog/urls

1  url(r'^$', views.index, name='index'),
2  url(r'^(?P<slug>[^\.]+)/$', views.view_post, name='view_post'),
3  url(r'^(?P<slug>[\w-]+)/$', views.view_category, name='view_category')

This is probably not a good URL strategy. Your view_category URL's overlap with your view_post URL's, which means that your view_category URL's will never work because [\w-]+ is contained within [^\.]+, which matches any character except for a \ and period, neither of which will ever be contained in a common slug format (used by view_category).

Wouldn't it be better and more obvious to namespace the URL's so that what you are matching is much more clear? Otherwise you'll have no way of telling a post apart from a category.

 

2  url(r'^post/(?P<slug>[^\.]+)/$', views.view_post, name='view_post'),
3  url(r'^category/(?P<slug>[\w-]+)/$', views.view_category, name='view_category')
