I'm getting an error when referencing detail.html in index.html

Reverse for 'detail' with arguments '(3,)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['$(?P<pk>[0-9]+)/$']

views.py

def rock_and_feat(request):
    feats = Feat.objects.order_by('-created')[:3]
    rocks = Rockinfo.objects.order_by('-rank')[:50]
    context = RequestContext(request, {
        'feats': feats, 'rocks': rocks
    })
    return render_to_response('template.html', context)


class DetailView(generic.DetailView):
    model = Feat
    template_name = 'feature/detail.html' 
    context_object_name = 'feat'

urls.py

urlpatterns = [
    url(r'^$', views.rock_and_feat, name='rock_and_feat'),
    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),
]

index.html

{% extends "index.html" %}
{% block mainmast %}
<div id="wrapper">
{% if feats %}
{% for feat in feats %}
 <div class="specialsticky">
 <a href="{% url 'feature:detail' feat.id %}"><img src="{{ feat.image.url }}" alt="some text"></a>
  <h1 class="mast-header">
    <a href="#">{{feat.title}}</a>
  </h1>
 </div>

 {% endfor %}
 {% else %}
<p>No </p>
 {% endif %}
</div>
{% endblock %}

detail.html

{% extends "index.html" %}

<iframe width="560" height="345" src="{{ feat.youtube_link }}"       frameborder="0" allowfullscreen></iframe>

project urls.py

from django.conf.urls import include, url
from django.contrib import admin
from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    url(r'^$', include('feature.urls', namespace="feature")),
    url(r'^admin/', include(admin.site.urls)),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

the app worked fine before I added the <a href= on the image in index.html.

Can't figure out what's wrong.

This indicates the problem.

'$(?P<pk>[0-9]+)/$'

There shouldn't be a dollar sign (which matches the end of the string) at the beginning of the pattern.

The problem is caused by the way you are including the urls.py. You currently have a dollar in the regex:

url(r'^$', include('feature.urls', namespace="feature")),

To fix the problem, remove the dollar from the regex. 

url(r'^', include('feature.urls', namespace="feature")),

    I'm sorry but I don't understand. The regular expression in `urls.py` as you can see above does not have a dollar before it. What changes are you asking me to make? I've edited the code above to add `urls.py` for the project. – WutWut Jun 08 '15 at 23:27

    Remove the dollar sign from the regex when you use include, i.e. `url(r'^', include('feature.urls', namespace="feature")),` – Alasdair Jun 09 '15 at 05:57
