원격 Heroku 응용 프로그램이 충돌합니다. 로컬 괜찮아요

Question

난 로컬로 작동 (bundle exec와 함께 테스트) 레일 애플 리케이션을 가지고 있지만 Heroku (시더 스택)에 추락했다. 이 구성은 원격지와 동일합니다 (둘 다 Postgres를 사용하고 있습니다). 스택 추적은 Rails/Thin 환경에서 발생하는 것처럼 보이기 때문에 실제로 충돌은 다소 혼란 스럽습니다. 내 vendor/plugins 디렉토리에는 아무 것도 없기 때문에, deprecation 경고는 똑같이 난처하게 만듭니다!

end 

Answer 1

귀하의 모델은 다음과 같아야합니다. 무슨 일이 있었는지

class Transcript < ActiveRecord::Base 
    attr_accessible :grade, :hours 

    belongs_to :student, class_name: 'User', dependent: :destroy 
    belongs_to :course
