Dear glenn,
Thanks for your reply. I try to add "url(r'^$', views.index, name='index'), in rango/urls.py" and reloads the web. But it still doesn't work too. Can you take a look at my code?
rango/urls.py
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^about/$', views.about, name='about'),
url(r'^add_category/$', views.add_category, name='add_category'),
url(r'^category/(?P<category_id>\d+)/$', views.category, name='category'),
url(r'^category/(?P<category_id>\d+)/add_page/$', views.add_page, name='add_page'),
url(r'^register/$', views.register, name='register'),
url(r'^login/$', views.user_login, name='login'),
url(r'^logout/$', views.user_logout, name='logout'),
url(r'^search/$', views.search, name='search'),
url(r'^profile/$', views.profile, name='profile'),
url(r'^goto/$', views.track_url, name='track_url'),
url(r'^like_category/$', views.like_category, name='like_category'),
url(r'^suggest_category/$', views.suggest_category, name='suggest_category'),
url(r'^my_cv/$', views.my_cv, name='my_cv'),
)
tango_with_django_project/urls.py
urlpatterns = patterns('',
url(r'^rango/', include('rango.urls')),
url(r'^admin/', include(admin.site.urls)),
)
