I know aggregates have been discussed a lot already and that the way to do it is at write time.
However my application is a full text search engine where each keyword produces a different result set. I need to report the sum and count for the entities in a given result set. Example: search a datastore of Contract entities where a Contract model has an attribute "contract_value". I need to get sum(contract_value) for all the entities for the search. How would you do this? Writing a count and sum for each possible search keyword is mind boggling. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
