哪裏的軌道有「ActiveRecord :: AssociationTypeMismatch」內的錯誤？

按軌道指導說：ActiveRecord::AssociationTypeMismatch應提高時，纔會有關聯的不匹配，但在我的情況下，其新的東西..哪裏的軌道有「ActiveRecord :: AssociationTypeMismatch」內的錯誤？

以下是例外：

ActiveRecord::AssociationTypeMismatch (Service(#50963840) expected, got Service(#70493480)):

參數跟蹤：

有人可以解釋什麼可能是可能的問題？

你可以發佈生成該日誌輸出的代碼嗎？ – 2012-04-10 14:31:41

@DylanMarkow實際上'active_admin'正在被使用，但它應該做些像'@ room.update_attributes（params [：room]）' – 2012-04-11 05:03:54
