Hi, Each GalleryObject can be a 'root' without any parent or it has a parent, which is another GalleryObject it is based on.
This means each GalleryObject may have a history of parents, grandparents, etc. How should I store this history? Store only the immediate parent or a list of those parents? Which is more efficient when I want to get a list of parents from the datastore. I think only storing the immediate parent will result in problems, no? Also how do I store this list of parents? By reference or using their index? (Each GalleryObject has an index (0,1,2,3, ...) So storing a list of GalleryObjects means either storing (0, 12, 55, 3234, ...) or (ref1key, ref2key, ref3key, ...) Which way would you suggest? I guess storing by using their index makes the most sense, no? Otherwise if I delete a GalleryObject it might be referenced by key somewhere else (what happens if I do this? won't it be deleted since a reference still points to it?) thanks...jago --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
