You might get a quicker result by doing a query direct to the DB and using its GROUP BY functionality: SELECT sum( s.amount_received ) - sum(amount_dispensed) as amount_on_hand, s.strength, r.name AS route, m.name AS medicine FROM stocks s JOIN medicines m ON s.medicine_id = m.id JOIN routes r ON s.route_id = r.id GROUP BY s.strength, r.name, m.name You can use this in a "find_by_sql" and iterate it as a normal array.... Not exactly Rails-y. but let's face it, we need to know what drugs are in the cupboard right now. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
