초기화되지 않은 상수 ActionController

Question

Backstory : 일부 친구와 저는 앱에서 작업 중이며 다른 페이지에서 처리 할 항목을 여러 개 선택하려고했습니다. RailsCast #165을 찾기 전에 지점을 만들고 3 개의 체크 박스가있는 테이블에 대한 비계를 추가하여 생성 된 코드가 어떻게 보이는지 확인했습니다. RC165에서 정답을 찾았을 때, 모든 코드와 마이그레이션을 삭제하고, 모든 작업을 포기할 것입니다.

아아아, 나는 그것에 대한 참조가 어떤 지점에서도 전혀 아무것도하지 못하게 막을 수 없으므로 나을 수없는 것처럼 보입니다. 언제 "레이크 dB : 마이그레이션"또는 "레일의"또는 아무것도, 내가 얻을 ...

uninitialized constant ActionController::MimeResponds::ChecksHelper (NameError) 

... 문자열 "확인이"어디서나 내 프로젝트 디렉토리에 나타나지 않는 경우에도. 나는에 관해서는 지금까지 갔을 :

1. 디렉토리 이름을 바꾸고 GitHub의에서 새 프로젝트를 복제 (참고 : 내 실험은, 로컬 파일 시스템 수준에서도 최선을 다하고 결코 더 적은을 추진).
2. 불어 멀리 위해 ​​Postgress 개발 및 테스트 데이터베이스

내가 어디에서 어떻게 레일 내 간단한 실험을 "기억"루비, 레일을 멀리 날려 짧은 생각에서 오전 이해하는 완전한 딱하다

하고, rbenv, 즉 근본적으로 기계를 긁어내는 것.

난처한 코드를 그냥 버리면 어렵다는 것을 믿을 수 없습니다.

이 문제를 해결하거나 미래에이를 피하는 방법에 대한 제안은 언제든지 환영합니다.

Answer 1

당신은 아마도 어떤 컨트롤러

helper :checks 

가있을 수 있습니다. 이렇게하면 레일이 해당 파일에서 위쪽으로 클래스를 인스턴스화합니다. 자동로드는 마지막으로로드 할 적절한 파일을 찾으려면 실패 할 경우, 오류가 일정한 클래스/먼저 검색 한 초기 네임 스페이스를 보여주기 때문에

이상한 오류 메시지입니다.
