NoReverseMatch implementing django-likes - django

Question

Getting the following error when trying to install django-likes
NoReverseMatch at /post/25/
Reverse for '' with arguments '('posts-post', 25, 1)' and keyword arguments '{}' not found. 0 pattern(s) tried: []
Exception Location: /Users/Pete/.virtualenvs/innerlocal-mvp/lib/python2.7/site-packages/django/core/urlresolvers.py in _reverse_with_prefix, line 463
I'm not sure where to even start on this error, I've done a lot of searching, but nothing comes up.
My view that this is referring to:
def single_post(request, id):
post = get_object_or_404(Post, id=id)
...
return render(request, 'posts/single_post.html', locals())
with {% likes post %} in the html.
and this line highlighted from the resulting html:
<a class="liker" href="{% url like content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>
I'm using Django 1.7 so wouldn't be surprised if that was a problem.
Any help would be greatly appreciated!!

Answer 1

Turns out that the app code needed a change:
In likes.html
from
<a class="liker" href="{% url like content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>
to
<a class="liker" href="{% url 'like' content_type content_obj.id 1 %}" rel="nofollow">{% trans "I Like" %}</a>
ie - the quotation marks around 'like'
