Hello guys. In the method [1] `ids_reader` at `ActiveRecord::Associations::CollectionAssociation` I think we can do a performance improvement when we are dealing with has_many through associations.
class User < ActiveRecord::Base > has_many :badge_items > has_many :badges, through: :badge_items > end In the scenario above when we do something like `User#badge_ids` the query called is: SELECT "badges".id > FROM "badges" > inner join "badge_items" > ON "badges"."id" = "badge_items"."badge_id" > WHERE "badge_items"."user_id" = 1 But would be great if we have this instead: SELECT "badge_items"."badge_id" > FROM "badge_items" > WHERE "badge_items"."user_id" = 1 Is this in your plans already? Can I help with anything about it?
