title: Passing parameter from template to view (link)
body: <p>I want to call a view from a template and pass parameters to the view (see below). However, the code throws the following error:</p>
  
  <pre><code>Reverse for 'project_list' with arguments '(u'member',)' and keyword arguments '{}' not found.
  </code></pre>
  
  <p><strong>from the template:</strong></p>
  
  <pre><code>&lt;a class="btn" href="{% url project_list 'member' %}"&gt;Member&lt;/a&gt;
  </code></pre>
  
  <p><strong>from the view:</strong></p>
  
  <pre><code>def project_list(request, projects_to_show = 'All'):
      if projects_to_show == 'member':
      ...
  </code></pre>
  
  <p><strong>from urls.py:</strong></p>
  
  <pre><code>url(r'^projects/$', 'project_app.views.project_list', name="project_list"),
  </code></pre>
  
  <p>What am I doing wrong?</p>
