title: Django model - Updating a attribute without touching lastmodified_at
body: <p>I'm creating a small wiki app and use a lastmodified_at attribute (<code>auto_now</code>). Now I'd like to count the view of my pages. </p>
  
  <p>My first thought was to add a field to my wiki article object and incarnate it by one if the <code>showArticle</code> view is called. </p>
  
  <p>Unfortunately this would cause the <code>lastmodified_at</code> to be updated as well.</p>
  
  <p>Is there another possibility then create an extra table which contains the article_id and the counter or to remove/rebuild my <code>auto_now</code> attribute?</p>
  
  <p>Thanks!</p>
