Here is an experimental patch to add generative aggregate methods on query objects.
My use case is that I have a class which is often queried with a sum query, from different places. But those different places usually add a filter on top of that basic query. And since I don't like repeating myself, I wanted a way to factor the common part. Here is some (untested) example: score_query = Query(Tag).sum_clause(tags_table.c.score1 * tags_table.c.score2) fun_score_query = score_query.filter_by(name='fun') [... on another place ...] user_fun_score = fun_score_query.filter_by(user=self).scalar() If you agree with the concept and way to do it, I'd happily complete it for the other aggregates and document it. PS: for such new feature suggestions, do you prefer if I add a ticket directly or if I discuss the thing here first? -- Gaëtan de Menten http://openhex.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
