Heroku는 앱이 잘 돌아가고 있다고 말하지만 오픈 소스 코드를 통해 오류 페이지로 리디렉션되고 있습니다. 내 로컬 컴퓨터에서 오류가 발생합니다. 나는 그것이 mongo와 관련이 있다고 의심한다, 나는 heroku를 위해 MongoHQ에 추가를 downlaoded했고,이 문제를 아직도 경험하고있다. 난 당신이 부가 기능은 Heroku가있는 MongoHQ를 설치 한 경우이 코드는

Answer 1

mongoid 사용하는 알고, 당신의 레일 응용 프로그램이 데이터베이스에 연결하는 데 사용할 수있는 MONGOHQ_URL 환경 변수를 작성합니다. config/mongoid.yml이 제대로 구성되지 않은 것 같습니다. 여기에 Heroku가 & MongoHQ에 대한 작업 예제 :이 도움이

development: 
    host: localhost 
    database: yourapp_dev 

test: 
    host: localhost 
    database: yourapp_test 

# set these environment variables on your prod server 
production: 
    uri: <%= ENV['MONGOHQ_URL'] %> 

희망!
