title: Django no reverse match found when passing parameters in {% url %}
body: <p>I have the following url conf:</p>
  
  <pre><code>      url(r'^tournaments/(?P&lt;tournament_id&gt;\d+)/imports/$',
           'club.apps.main.views.imports_view',
           name='imports_tournament'),
  </code></pre>
  
  <p>And the following template tag:</p>
  
  <pre><code>{% url 'imports_tournament' tournament.id%}
  </code></pre>
  
  <p>However, this always raises no reverse url match found error.</p>
  
  <p>Django version is 1.5, so the single quoted syntax should work..</p>
  
  <p>What am I doing wrong?</p>
