{속성} 4.1.5

내가 활성 기록에서 반환 된 배열을 얻을 수 find_all_by 사용하고 액티브 작동하지 않습니다 find_all_by_,이 기능은 레일에 적합합니다 (4.0.0){속성} 4.1.5

Loading production environment (Rails 4.0.0) 
2.0.0-p353 :001 > Subscription.find_all_by_id 123 
=> []

그러나 나는 레일 (4.1.5)로 변경하는 경우, find_all_by이 작동하고, 또는 주변의 일을 해결하기 위해

Loading production environment (Rails 4.1.5) 
2.0.0-p481 :001 > Subscription.find_all_by_id 123
