You can simply do [entity.parent for entity in result]. If you have a ReferenceProperty, the first time you call the property "parent" to get the key, it'll be fetched. So building and fetching a list would only be possible if you store an additional property with the parent key - or you'd be doing double fetch. -- rodrigo --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
