Heroku/Ruby에서 "순환 적 종속성이 자동 상수 동안 검색 됨"오류를 수정하는 방법

Question

배포 후 Heroku에서이 오류가 발생하지만 오류가 발생하지 않거나이 문제가 로컬에서 발생하지 않습니다.

다음 이름/네임 스페이스 등의 문제는 무엇입니까? 내가 뭘 놓치고 있니?

모델/문제/구매/finalize_utils.rb

module Purchase::FinalizeUtils 
    extend ActiveSupport::Concern 
end 

모델/purchase.rb

class Purchase < ActiveRecord::Base 
    include FinalizeUtils 
end 

로그 오류 : 그것은 미래의 사람들을위한 가치 무엇이 들어

Answer 1

이 문제는 내 문제가 사물의 조합이라는 것을 발견했습니다. 하나

이 생산 및 개발이 설정했습니다 다른 경우 작동 된 이유 :

config.eager_load 

이 비슷한 "설정"에 대한 실패하지 않은되지 않은 이유 (즉, 사용자 :: 인 MyModule) eager_loading을 위해 파일을 처리하는 순서와 관련이있는 것 같습니다.

문제는 모델 이전에 문제가 발생하는 것처럼 보였을 때가 있었고 때로는 그 반대의 경우도있었습니다. 클래스 구매가 동일한 클래스로 보이지 않았기 때문에 두 버전 모두에 문제가 있습니다 (하나는 하위 클래스 였고 하나는 그렇지 않았기 때문에). 제대로 다시 열리지 않았습니다.

그래서 나는이를 변경하기 위해 필요한이에

module Purchase::FinalizeUtils 
    extend ActiveSupport::Concern 
end 

:

#models/concerns/purchase/finalize_utils.rb 
class Purchase < ActiveRecord::Base 
    module FinalizeUtils 
    extend ActiveSupport::Concern 
    end 
    end 
end 

를이 클래스 구매가 재개 대신 재정의 할 수있었습니다. 아니면 그런 식으로. 저 같이 포함 내 우려를 네임 스페이스 할 수 있습니다 위의 방법 중 하나의 방법 :

파일은 게으른 로딩에 의해 발견되는 이름,하지만 모듈이 클래스에 있기 때문에, 조회 경로가 발견되지

#models/purchase.rb 
class Purchase < ActiveRecord::Base 
    include FinalizeUtils 
end 

.
