Question

I was trying out the url template tag and stumbled on a issue:

Caught NoReverseMatch while rendering: Reverse for ''location'' with arguments 
'(<City: New York>,)' and keyword arguments '{}' not found.

In my template file I have:

{% url 'location' city_name=city.name %}

url.py

url(r'^location/(?P<city_name>.*)/$', CityView.as_view(), name="location"), 

models.py

def get_absolute_url(self):                                                                                                                                                                               
    return "/location/%s" % self.name

Updated thanks to Maik Hoepfel in the comments:

Pre Django-1.5, You don’t need the ' marks in:

{% url 'location' city_name=city.name %}

however you can enable them by loading url from the future module. Rather than {% load url %} use {% load url from future %}.

In your case, pre-Django 1.5 and without the future version of url, you can use:

{% url location city_name=city.name %}

I suspect it can’t find your name value because it is literally looking for 'location'.
