This probably happens because you're in development mode where the AR model classes are not all automatically loaded, so if you find through Order you only get Order and ItemCollection because neither is aware of the existance of ReplenishmentOrder until it has been loaded.
A hack fix for this is to put: "require_association 'order'" at the bottom of item_collection.rb and "require_association 'replenishment_order'" at the bottom of order.rb On K, 2008-10-29 at 03:22 -0700, zubin wrote: > Hi, on Rails 2.2RC1 I've found a what appears to be a bug in > ActiveRecord STI classes: > > class ItemCollection < ActiveRecord::Base > class Order < ItemCollection > class ReplenishmentOrder < Order > > The problem is that instances of ReplenishmentOrder are initially not > found via Order.find(:id), as shown below. > After searching the subclass directly (second query), the SQL of > searching the parent class changes (see third query in log below). > > Console: > > >> Order.find(510) > ActiveRecord::RecordNotFound: Couldn't find Order with ID=510 > from /Users/zubin/ww/g2/vendor/rails/activerecord/lib/ > active_record/base.rb:1528:in `find_one' > from /Users/zubin/ww/g2/vendor/rails/activerecord/lib/ > active_record/base.rb:1511:in `find_from_ids' > from /Users/zubin/ww/g2/vendor/rails/activerecord/lib/ > active_record/base.rb:590:in `find' > from (irb):1 > >> ReplenishmentOrder.find(510) > => #<ReplenishmentOrder id: 510, parent_id: nil, user_id: 28, > payment_method_id: nil, billing_address_id: 1, shipping_address_id: 1, > type: "ReplenishmentOrder", status: "editing", ref: nil, > despatched_at: nil, created_at: "2008-10-28 04:42:54", updated_at: > "2008-10-29 05:04:30", total: #<BigDecimal:5d92998,'0.0',4(8)>, > freight_total: #<BigDecimal:5d9295c,'0.0',4(8)>, redeemed_total: > #<BigDecimal:5d92920,'0.0',4(8)>> > >> Order.find(510) > => #<ReplenishmentOrder id: 510, parent_id: nil, user_id: 28, > payment_method_id: nil, billing_address_id: 1, shipping_address_id: 1, > type: "ReplenishmentOrder", status: "editing", ref: nil, > despatched_at: nil, created_at: "2008-10-28 04:42:54", updated_at: > "2008-10-29 05:04:30", total: #<BigDecimal:5d8ff54,'0.0',4(8)>, > freight_total: #<BigDecimal:5d8ff18,'0.0',4(8)>, redeemed_total: > #<BigDecimal:5d8fedc,'0.0',4(8)>> > >> > > Log: > > $ tail log/development.log > Order Columns (185.4ms) SHOW FIELDS FROM `item_collections` > Order Load (97.8ms) SELECT * FROM `item_collections` WHERE > (`item_collections`.`id` = 510) AND ( (`item_collections`.`type` = > 'Order' ) ) > ReplenishmentOrder Columns (2.5ms) SHOW FIELDS FROM > `item_collections` > ReplenishmentOrder Load (0.4ms) SELECT * FROM `item_collections` > WHERE (`item_collections`.`id` = 510) AND ( (`item_collections`.`type` > = 'ReplenishmentOrder' ) ) > Order Load (0.5ms) SELECT * FROM `item_collections` WHERE > (`item_collections`.`id` = 510) AND ( (`item_collections`.`type` = > 'Order' OR `item_collections`.`type` = 'ReplenishmentOrder' ) ) > > -Zubin > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
