토론 #1

시스템의 나머지 부분은 cancan이 있는 컨트롤러를 포함하여 정상적으로 작동합니다.더 이상 설치할 수 없어요.

토론 #2

추적은 무엇을 보여 줍니까?

may cancangem 버전은 cancan(1.0.2)standard_exception_handling' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:in입니다. 프로그램 컨트롤러의rescue from 자구 때문에 발생한 것으로 추정됩니다. 이 자구는 gm를 설치하지 않았을 때 터치됩니다.나는 인자를 문자열로 바꾸어야 할 수도 있다.기사 고마워요.

토론 #4

안녕, 리안, 나는 응용 프로그램 컨트롤러에'require'cancan'을 추가해서 이 오류를 없앴다.
... 첫 번째 답은 죄송합니다. 문제는 플러그인이 초기화되기 전에 프로그램 controler가 필요하다는 것입니다...다음은 제 솔루션입니다.

문구는 컨트롤러/모델 파일 이외에 저장하는 것이 좋으나 환경 설정 파일, 초기 값 설정 항목, bundler (사용하면) 내부에 저장하는 것이 좋습니다.어차피 이게 관례야.
만약 내가 오류를 정확하게 이해한다면,

토론 #6

부분을 require 의 문자열에 넣으면 그것을 복구할 수 있을 것이다.CanCan::AccessDenied 나는 이미 이 두 가지 해결 방안의 도움말과 효과를 테스트했다. 물론 문자열을 가진 해결 방안이 더 깨끗하다:)ApplicationController헤이,ryanb,

만 붙이면 Puma를 다시 시작할 수 있습니다.
