사이트가 heroku에서 실행 중이고 ActiveRecord 오류가 로컬로 발생했습니다

Question

Heroku에서 첫 번째 사이트를 배포하려고합니다. 나는 모든 것을 준비했고 내가 Heroku에 밀린 물건들은 잘 돌아 간다. 내가 로컬 테스트 감독을 실행할 때 내가 얻을 :

ActiveRecord::ConnectionNotEstablished

내가 레일 및 Heroku가에 새로 온 사람이 알아낼 수 없습니다. 사이트는 매우 기본입니다. No db, 트위터 부트 스트랩에서 navbar가있는 단순한 html 페이지.

Answer 1

기본적으로 Rails는 데이터베이스에 대한 연결을 만듭니다. 이 연결을 제거하는 몇 가지 방법이 있습니다 (Rails에서 ActiveRecord를 제거하여).

새로운 레일스 프로젝트를 만들려면 --skip-activerecord 명령을 사용하여 ActiveRecord를 비활성화 할 수 있습니다. 이미 생성 된 프로젝트를 변환하려면 수동으로 다시 구성해야합니다. http://mikewilliamson.wordpress.com/2011/03/21/running-rails-3-with-no-activerecord

Heroku에 대해서는 Heroku가 프로젝트에 데이터베이스 연결을 삽입하기 때문에 작동합니다.
