Hi I am using following URL patterns in django and I am wondering that where is problem and why it is not able to find it. Following screenshot shows my URL as well as expected URLs.

Please tell that where I am making mistake. Please tell if some thing else I can tell to understand problem. I was looking on it for almost an hour or 2 and then I posted it on stackoverflow.com so hope I will get some solution.
Adding urls.py here:
from django.conf.urls.defaults import patterns, include, url
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'ecomstore.views.home', name='home'),
#url(r'^catalog/', 'preview.views.home'),
# url(r'^ecomstore/', include('ecomstore.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
url(r'',include('catalog.urls')),
)
Then urls.py of catalog app:
from django.conf.urls.defaults import *
urlpatterns=patterns('catalog.views',
(r'^$','index',{'template_name':'catalog/index.html'},'catalog_home'),
(r'^category/(?P<category_slug>[-\w]+)/$','show_category',{'template_name':'catalog/category.html'},'catalog_category'),
(r'^product/(?P<product_slug>[-_\w+])/$','show_product',{'template_name':'catalog/product.html'},'catalog_product'),
)
thanks in advance guys.
referring to my comment: at least one thing wrong is that you have an extra slash before “product”. You want ^product, not ^/product. That might be all but it’s a little hard to tell from the pic.
also, correct me if I’m wrong, because I haven’t used regexes in a while, but doesn’t [-_\w+] only match – OR _ OR \w+?
“[ ]
Match anything inside the square brackets for ONE character position once and only once, for example, [12] means match the target to 1 and if that does not match then match the target to 2 while [0123456789] means match to any character in the range 0 to 9.”

so you’d want… [-_]\w+ ?
