Problem solved. I missed a step in the tutorial where name spacing in
the root URLconf was discussed. I still don't understand it completely
but the bottom line is that the line number 4 in the file index.html
should be replaced with
<li><a href="{% url 'polls:detail' poll.id %}">{{ poll.question }}</a></li>

Hi everyone. I am trying to walk through the polls tutorial. I am stuck
at the part 4 after the change of the views from function based to class
based. A search in Google brought plenty results but none of them seems
to be related exactly to this situation or maybe it is over my head to
understand what is going on.
When I visit http://127.0.0.1:8000/polls/ i get
NoReverseMatch at /polls/
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}'
not found.
Request Method: GET
Request URL: http://127.0.0.1:8000/polls/
Django Version: 1.5.2
Exception Type: NoReverseMatch
Exception Value:
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}'
not found.
...
In template
/home/voger/PycharmProjects/mysite/polls/templates/polls/index.html,
error at line 4
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}'
not found.
1 {% if latest_poll_list %}
2 <ul>
3 {% for poll in latest_poll_list %}
4 <li><a href="{% url 'detail' poll.id %}">{{ poll.question }}</a></li>
5 {% endfor %}
6 </ul>
7 {% else %}
8 <p>No polls are available.</p>
9 {% endif %}
The offending line is line number 4. The classes used are
class IndexView(generic.ListView):
template_name = 'polls/index.html'
context_object_name = 'latest_poll_list'
def get_queryset(self):
"""Return the last five published polls."""
return Poll.objects.order_by('-pub_date')[:5]
class DetailView(generic.DetailView):
model = Poll
template_name = 'polls/detail.html'
and in /polls/urls.py the urls are
urlpatterns = patterns('',
url(r'^$', views.IndexView.as_view(), name='index'),
url(r'^(?P<pk>\d+)/$', views.DetailView.as_view(), name='detail'),
url(r'^(?P<pk>\d+)/results/$', views.ResultsView.as_view(),
name='results'),
url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)
Can someone please explain what is wrong?
