Hi Django group,

I'm following the tutorial and get stuck on part 3, Removing hardcoded URLs in templates

I read through the topics that discuss this, but can't find the issue in my case.

my detail.html template looks like

<h1>{{ question.question_text }}</h1>
<ul>
{% for choice in question.choice_set.all %}
    <li><a href="{% url 'detail' question.id %}">{{ choice.choice_text }}</a></li>
{% endfor %}
</ul>

in my urls.py for the polls project I have

urlpatterns = [
     url(r'^$', 'index', name="index"),
     url(r'^(?P<question_id>\d+)/$', views.detail, name="detail"),
     url(r'^(?P<question_id>\d+)/results/$', 'results', name="results"),
     url(r'^(?P<poll_id>\d+)/vote/$', 'vote', name="vote"),
]

Thanks for any suggestion,
jack
