ruby를 1.8.7에서 1.9.2로 업그레이드 한 후 로컬 서버 오류 (Rails 3.1.1 포함)

Question

방금 ​​rvm을 설치했고 rvm을 사용하여 1.8.7에서 1.9.2로 업그레이드했습니다. 내 응용 프로그램에 번들 설치를 실행하여 내 보석을 다시 설치했습니다. 내가 로컬 레일 서버를 실행하고 로컬 호스트에 브라우저를 탐색 할 때 : 3000, 다음과 같은 오류가 서버 로그에 표시 :

Started GET "/" for 127.0.0.1 at 2012-01-25 20:10:12 -0800 

TypeError (class Date needs to have method `_load'):

나는 나의 무지를 용서하십시오, 레일즈 멍청한 놈의 비트입니다. 어떤 도움이라도 대단히 감사 할 것입니다.

삭제 쿠키 :

이 여기에 전체 추적의 앱이 세션을 저장한다 (이는 정렬 화 루비 객체) 쿠키한다.

DELETE FROM sessions; 

: 내가 올바르게 그는 프로덕션 응용 프로그램을 업데이트하는 동안 앱이 더 이상 오래된 세션

Answer 2

를로드 할 수 있도록 형식 1.8과 1.9 사이에 변경 마샬링 기억한다면, 나는 모든 세션을 삭제하여 문제를 해결할 수 있었다

(SQL을 사용하는 DB에서 - 사용자가 쿠키를 지울 필요가 없도록)
