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