작동하지 해시 : 3.2.1 루비 : 루비 1.9.3p0 (2011-10-30 수요일 수정 33570)는 i686 리눅스].레일 3.2.1 redirect_to 옵션 레일 사용
가 자격 증명을 (폼 값) received.If의 유효성 검사가 실패의 유효성을 확인 방법 sign_in 내 HelloController.rb 번호, 그것은 login_page을 렌더링합니다.
검증이 성공하면
는 자격 증명이 올바른지 발견하는 경우 사용자 자격 증명이 이 작품redirect_to "/games" # works
을 재 인증 아래 하나가 작동하지 않는 동안
redirect_to {controller:"games", action:"index"} # Doesn't work
Output:
Routing Error
No route matches [GET] "/hello/sign_in"
그러나 내 UsersController.rb 번호에서 리디렉션 옵션의 같은 스타일을 사용 http://localhost:3000/hello/sign_in 잘 작동 리디렉션, 방법을 만들
후자의 경우는 나에게 같은 오류를 보여줍니다. 검증하지만 다음 동안, 나는이 작품
redirect_to "/hello/login_page", :notice => "User Id and Password don't match" # works
다음 사용자에게 사용자 ID/암호가이 사건을 match.In하지 않는 메시지와 함께 로그인 페이지를 표시 할 필요가 또한
자격 증명이 올바른지 찾을 수없는 경우
,redirect_to {controller:"hello", action:"login_page" notice: "User Id and Password don't match" } # Doesn't work
작동하지 않습니다 나는 그런 행동 뒤에 이유가 무엇인지 이해하고 싶습니다.
