title: Exclude field from values() or values_list()
body: <p>Is there an efficient way to exclude fields from the function <code>values()</code> or <code>values_list</code>.</p>
  
  <p>e.g</p>
  
  <pre><code>Videos.objects.filter(id=1).get().values()
  </code></pre>
  
  <p>I want to exclude from this queryset the field <code>duration</code>.</p>
  
  <p>I know that I can specify fields what I want to have in the result but what if I want everything but only one field not. Like in the cases if I have 20 fields and if I want only one from them not.</p>
  
  <p>Thanks</p>
