RUBY-ON-RAILS오류 ArgumentError :와 ApplicationController의 사본 모듈 트리에서 제거하지만 여전히 활성화되어
나는 레일 4.0.0.rc2와 (레일 4 사용자 정의 gemset와) ActiveAdmin을 사용하고 있습니다. 응용 프로그램은 또한 railscasts # 385과 # 386을 기반으로 맞춤형 인증 코드를 가지고있다.
나는 ActiveAdmin을 리소스 파일에 뭔가를 변경하고 브라우저 페이지를 새로 고침 할 때, 나는 current_permission 방법에서이 오류가 발생합니다 :
내가 다시 새로 고침을하려고하면, 내가 얻을 :
나는이 문제가 소스 파일의 변경 후, 개발 모드에서 클래스의 자동 로딩 함께 할 수있는 뭔가가 생각합니다. 나는 비슷한 문제 게시물을 봐 왔지만, 그들은 레일 2.3.x.위한 또한,이 솔루션은이 오류를 던지는 컨트롤러에 드 할 지정하는 것 같다,하지만 난 곳 ActiveAdmin을이 조각에 넣어하는 방법 확실하지 않다.
이 ActiveAdmin을 하나와 아무 상관이 없을 수 있습니다. 이 권한 클래스가 내장 응용 프로그램 컨트롤러 내에서 사용 된 방법에 대해 수 있습니다. 나는 skip_before_filter을 추가하는 경우 : 권한 부여를 ActiveAdmin을 자원 클래스에이 오류가 사라진다.
와 ApplicationController :

1.나는 이런 일이 이유를 정확하게 모르겠지만, 나는 workaound을 발견했다. 이 변경 :
나는 이런 일이 이유를 정확하게 모르겠지만, 나는 workaound을 발견했다. 이 변경 :
def current_permission @current_permission ||= Permissions.permission_for(current_user) end이에:
def current_permission @current_permission ||= ::Permissions.permission_for(current_user) end이 오류는 ActiveSupport이 시점에서 발생합니다 :
# Load the constant named +const_name+ which is missing from +from_mod+. If # it is not possible to load the constant into from_mod, try its parent # module using +const_missing+. def load_missing_constant(from_mod, const_name) log_call from_mod, const_name unless qualified_const_defined?(from_mod.name) && Inflector.constantize(from_mod.name).equal?(from_mod) raise ArgumentError, "A copy of #{from_mod} has been removed from the module tree but is still active!" end # ... end완전히 상수 이름을 필요하지 않은 경우 문제는 그래서와 ApplicationController 네임 스페이스를 찾는 시도를 레일 발생합니다.

2.미래 방문자를 위해, 나는 질문은 꽤 오래하고 허용 대답은 이미 비록 내가 원래 문제에 대한 몇 가지 설명을 제공 할 것이라고 생각합니다.

하면 ArgumentError : A는 X의 복사는 모듈 트리에서 제거하지만 여전히 자동 (LIB 디렉토리에) 다시로드되지 않은 하나에서 액세스 (응용 프로그램 디렉토리에) 자동으로 다시로드 클래스를하려고 할 때 발생합니다 활성화되었습니다.

3.나는 ActiveAdmin을 사용하지 않는,하지만 난 그냥와 ApplicationController와 순환 종속성을 경험했다.
나는 ActiveAdmin을 사용하지 않는,하지만 난 그냥와 ApplicationController와 순환 종속성을 경험했다.
문제는 도우미 모듈이 잘못 선언 하였다 :
app/helpers/home_helper.rb선언했다 :
module StaticHelper이 문제를 해결 한 후, 모든 복숭아이었다. 이런 일이하고 레일이 더 지능적인 오류 메시지를 반환하지 않은 이유를 연구하지 않았다.

4.당신에 임시로 넣어 시도 development.rb
당신에 임시로 넣어 시도 development.rb
config.cache_classes = true그것은 나를 위해 일했습니다.

5.당신은 당신의 설정 / 초기화 / active_admin.rb이 줄을 추가 시도 할 수 있습니다 :
당신은 당신의 설정 / 초기화 / active_admin.rb이 줄을 추가 시도 할 수 있습니다 :
레일 <= 4 :

config.skip_before_action :load_footer_variables마찬가지로 여기에 제안했다.
