title: Redirection is leading me to Page not found error in Django
body: <p>Project urls.py includes app urls. I am using HttpResponseRedirect to get Likes posted on site. I am not trying to call for template so this is why not using render_to_response. My app view is:</p>
  
  <pre><code>def like_article(request, article_id):
      if article_id:
          a = Article.objects.get(id=article_id)
          count = a.likes
          count += 1
          a.likes = count
          a.save()
      return HttpResponseRedirect('articles/get/%s' % article_id)
  </code></pre>
  
  <p>My app urls.py reflects likes redirection like this:</p>
  
  <pre><code>    url(r'^like/(?P&lt;article_id&gt;\d+)/$', 'article.views.like_article'),
  </code></pre>
  
  <p>My parent "articles" HTML file extended from base says:</p>
  
  <pre><code>    &lt;p&gt;{{article.likes}} people liked this article&lt;/p&gt;
  </code></pre>
  
  <p>My single article page extended from base.html shows:</p>
  
  <pre><code>    &lt;p&gt;&lt;a href="/articles/like/{{article.id}}"&gt;Like&lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>Please advise.</p>
