title: Why doesn't Django serialize FileField to the file url when using AWS S3
body: <p>Scenario: I'm using Amazon S3 as default storage using S3 Boto and all files would be going to <strong>'media'</strong> folder in my bucket.</p>
  
  <p>Question: When I am serializing the model containing my FileField to json using <code>serializers.serialize</code>, all I get in the json is <strong>'media/abc.png'</strong> or something of that sort. Is there a way to automatically get the file url in json instead of the relative path or should I manually append the url into the json response every time?</p>
