레일을 "정의되지 않은 지역 변수 또는 메소드"로 다시 채우지 않는 attr에 대해서

나는 여기를 잃고있다. Dev 모드 (스크립트/서버)에서 실행 중일 때 나는 내 모델 번호에 대한 항목을 나열하려고 할 때 임의의 시간에 "undefined local variable or method 'id' for #<InsertModelNameHere:0x7f19bdb87dc8>"오류가 발생합니다. 페이지가 새로 고쳐지면 잘 작동하며 각 요청마다 모든 항목이 다시로드되기 때문에 dev에서만 볼 수 있다고 가정합니다. 경주 조건이 나 어쩌면 어쩌면? 나는이 문제가있는보기에서 "id"속성 (다른 키 명명 규칙을 사용하는 레거시 테이블)을 참조하지 않습니다. 동료 중 한 명이 레일스가 "id"속성을 모델에서 정의 된 기본 키.레일을 "정의되지 않은 지역 변수 또는 메소드"로 다시 채우지 않는 attr에 대해서

다음은보기, 오류 메시지 및 스택 추적을위한 코드입니다. 나는 레일 2.3.3을 달리고있다.

TODO 모델은 어떻게 생겼습니까? – ErsatzRyan

특히 fk_resource_id 메소드 – ErsatzRyan

fk_resource_id는 db의 열 –

당신이 할 일에 primary_key와 설정이 있나요?

class Todo 
    set_primary_key 'pk_todo_id' 

end

문제 일 수 있습니다. 무슨 일이 일어나는지 알려줘.

행운을 빈다.

예, 이미 설정했습니다 –

이것은 veiw을 칠 때마다 발생하지 않습니다. 어쩌면 시간의 절반이 걸릴 것입니다. –

안녕 스콧, 아마도 이것은 2.3.3 문제 일 것입니다. 참조 : https://rails.lighthouseapp.com/projects/8994/tickets/2948-exception-a-copy-of-actorscontroller-has-been-removed-from-the-module-tree-but-is-still- 활성 상태이며 가능한 해결 방법은 http://github.com/rails/rails/commit/d37ac7958fc88fdbf37a8948102f6b4e45c530b3입니다. 우리는이 문제가 있었는데, 분명히 생산 모드 나 씬 서버에서는 발생하지 않습니다. 씬 (thin)을 사용해 보거나 프로덕션 모드에서 다시 생성 해보십시오. 클래스가 잘못로드되어 실제 클래스 대신에 Todo 스텁이로드되므로 기본 키가 건너 뜁니다. – mixonic

패치를 제대로 적용 할 수 없기 때문에 2.3.2로 되돌릴 것입니다. 나는 이것이 문제라고 가정 할 것이다. 특히 2.3.3에 한정되어있다. 모두 도움을 주셔서 감사합니다.

예, dev를 직접 실행하기 위해 thin을 사용하여 작업하고 있습니다. 2.3.3은 지저분한 릴리스였습니다. – mixonic
