When the patterns are not properly configured in urls.py, for instance in this case: {{{ urlpatterns = patterns('', # notice that i forgot to do 'polls.views' here (r'^$', 'index'), (r'^(?P\d+)/$', 'detail'), (r'^(?P\d+)/results/$', 'results'), (r'^(?P\d+)/vote/$', 'vote'), ) }}} The error just says 'str' object is not callable (I'm attaching full HTML). Digging further down I saw in Local args that callback = detail, and that raised the suspicion and I found it. I think a more meaningful error, saying that the URL was matched to callback 'detail' and the corresponding view could not be found, would be nice.",,closed,Uncategorized,1.2,,duplicate,,,Unreviewed,0,0,0,0,0,0
