Question

Any ideas why this returns a NoReverseMatch error? From a fork of djano-ratings called updown.

urls.py:

url(r'^(?P<object_id>\d+)/rate/(?P<score>[\d\-]+)/$', AddRatingFromModel(), {
    'app_label': 'appname',
    'model': 'Thing',
    'field_name': 'rating',
}, name='thing_rating'),

The template:

<div id='vote'><a href='{% url thing_rating %}'>Up</a></div>

Thanks for any ideas!

EDIT: added view for clarity

def index(request):
    thing_list = Thing.objects.all()
    return render_to_response('index.html',
                         {'thing_list':thing_list},
                         context_instance=RequestContext(request))

You need to pass in arguments (I use keyword args here, but positional is okay too) for the url’s parameters.

In a list view, you’re probably iterating over your items, so something like this works:

{% for thing in thing_list %}
    ...
    <div id='vote'><a href='{% url "thing_rating" object_id=thing.id score=5 %}'>Up</a></div>
    ...
{% endfor %}

I think you also need quotes around the url name.
