title: Django Rest Framework serialize permission
body: <p>I would like to serialize object level permission - and send a simple <code>True</code> or <code>False</code> to the  browser - so accordingly I trigger the "allow editing" code.</p>
  
  <p>I am doing this so the user does not have functionality presented to them that they cannot use.</p>
  
  <p>Is there a built in way to do this? The docs do not allude to this.</p>
  
  <p>I have attempted the following on the serializer:</p>
  
  <pre><code>has_permission = serializers.SerializerMethodField('check_permission')
  
  def check_permission(self, obj):
      return self.check_object_permissions(self.request, obj)
  </code></pre>
  
  <p>but the serializer does not have the method <code>check_object_permissions</code> - that belongs to the permission object. </p>
