How would "you" approach storing and rendering comments in a reddit like forum? The naive approach i think would be to store comments with references to their parent comment, then recursively build the forum tree by retrieving children. I'm sure that would timeout for larger threads.
One interesting alternative i found was here: http://github.com/DocSavage/bloog/tree/master/models/blog.py#L137 basically each comment stores it's "genealogy" in a string, making comments lexically orderable. But that has a number of limitations - the genealogy string is limited to 500 bytes so there's suddenly a maximum thread depth, and the ids may exceed the fixed size padded space. At first i thought i could solve this by using list properties to encode the genealogy - then i realized that datastore lists have weird set-like sorting :\ .. Not sure whether i can salvage this approach. Can custom properties define their own sorting rules? Any suggestions/insights would be great. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
