title: Django Restframework: What view to use for statistical summary of queryset?
body: <p>Django Restframework provides generic views for lists and single models from querysets. Which view class would be most appropriate for creating an endpoint that serves a statistical summary of a queryset?</p>
  
  <p>I could surely build an APIView from scratch but I would like to reuse most of the settings on the ListAPIView (such as get_queryset, permission_classes, etc.) as well as url parameters. </p>
  
  <p>The endpoints will be organized like this:</p>
  
  <pre><code>/api/data/           # data endpoint
  /api/data/summary/   # summary endpoint
  </code></pre>
  
  <p>The summary endpoint will provide a single object that is not related to a single model instance.</p>
  
  <p>Thank you for any best practice advice.</p>
