There's been a fair bit of cross-talk about which URL's are actually the problem, but you only have one that would work for the view you are trying to call: url(r'^code/(?P<slug>[\w-]+)/$', CodeDetailView.as_view(), name='family'), At this point I can't tell which URL you are talking about, so I don't know if you are executing/matching the right one. The error would indicate that you are matching just r'code/' without the (?P<slug>), so the view has no way to look up the correct object to return. -James -- You received this message because you are subscribed to the Google Groups "Django users" group.
