개발 데이터베이스를 사용하는 Heroku의 DataMapper 연결은 ENV [ 'DATABASE_URL']가 아닙니까?

Question

제 문제는 Heroku DataMapper에 배포 할 때 데이터베이스 연결 정보가 DataMapper.setup(:default, ENV['DATABASE_URL'] || 'postgres://postgres:myohmysosecret@localhost/recall') 일 때 데이터베이스 연결 정보 'postgres://postgres:myohmysosecret@localhost/recall' 부분을 사용하려고 시도한다는 것입니다. 여기

내 Heroku가 로그 파일 : 나는이 문제를 가지고있다

Answer 1

, Heroku tutorial에 다음, 관련이있을 듯 결국, 그러나 겉으로는 오류 :

ENV['DATABASE_URL'] 

기본적으로 데이터베이스가없는 것 같습니다. Running heroku config이이를 보여줍니다. 그런 다음

heroku addons:add heroku-postgresql:dev 

을하거나 데이터베이스 문자열을 얻기 위해 다시 heroku config를 실행하거나, 당신은 아마 당신의 DataMapper.setup에 다음 줄을 사용할 수 있습니다 : 당신은 자세한 here로, 당신을 위해 데이터베이스를 만드는 다음 줄을 실행할 수 있습니다 :

ENV['HEROKU_POSTGRESQL_CYAN_URL'] 

희망이 있습니다. 나는 이것을 자신의 Heroku 지원 티켓에 추가하여 그들이 말하는 것을 보았습니다!
