heroku에서 마이 그 레이션을 실행할 때의 문제

Question

다음은이 게시물 인 Rails, data structure and performance에 대한 후속 작업으로 여기에 레일스에 카운터 캐시를 만들려고했습니다. 기본값을 0으로 설정하지 않으려면 데이터베이스의 기존 카운트 값으로 열을 업데이트하는 작업을 추가했습니다.

Running rake db : running on development은 (는) 몇 시간이 걸렸지 만 잘 작동합니다.

그러나 Heroku가와 마이그레이션이 나에게 다음과 같은 오류를주고 실행 : 나는 몇 가지 다른 일을 시도했지만이 시점에서 잃어버린 것 같다

는, 어떤 도움에 감사드립니다! 이상한 점은 오류 메시지가 항상 즉시 발생하는 것은 아니라는 점입니다. 마이그레이션이 실행되는 것처럼 10 분에서 20 분 정도 걸리는 경우도 있습니다.

감사

업데이트

:

class AddVotesCount < ActiveRecord::Migration 
    def self.up 
    add_column :options, :votes_count, :integer, :default => 0 
    Option.all.each do |option| 
     option.votes_count = option.votes.count 
     option.save! 
    end 
    end 

    def self.down 
    remove_column :options, :votes_count 
    end 
end 

업데이트 2 : 여기 내 마이그레이션 파일의 내용입니다이에게 Heroku와 스테이징 환경에서 작동이 ...하지만 생산

의 후 수정 사항은 거의 없으며 이전 코드는 다음과 같습니다.

def self.up 
    add_column :options, :votes_count, :integer, :default => 0 
    Option.reset_column_information 
    Option.find_each do |option| 
     Option.reset_counters option.id, :votes 
    end 

ROR은 다음과 같은 에러에 직면 할 수 사람들을 위해

Answer 1

, 나는 Heroku가 연락을했고 그들은이와 마이그레이션 실행하는 나에게 말했다 : 다음

$ heroku run bash --app appname 

$ rake db:migrate 

을

어떤 이유로 든 작동 ...
