An entity's parent is encoded in it's key. The parent can be any other entity, of whatever type. When you call Model.get_by_ids() it needs to construct the keys. It know the entity type, and you pass it the id. How does it know what arbitrary parent the entity may or may not have? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
