title: How to serialize Django queryset.values() into json?
body: <p>I have a model that has many fields, however for this problem I only need 3 of those fields. When I try to serialize a <code>.values</code> set I get an exception:</p>
  
  <blockquote>
    <p>'dict' object has no attribute '_meta'</p>
  </blockquote>
  
  <p>This is my code:</p>
  
  <pre><code>queryset = myModel.objects.filter(foo_icontains=bar).values('f1', 'f2', 'f3')
  serialized_q = serializers.serialize('json', queryset, ensure_ascii=False)
  </code></pre>
