Heroku上的Rails：ActiveRecord :: StatementInvalid，重置和迁移不起作用

当我尝试打开刚刚推送到heroku的应用程序时，出现以下错误，本地一切正常。我试过删除并重新推送，使用rake db：reset，pg：reset，db：migrate，并且所有表都有复数名称。我也在每一步后重新启动数据库显示在Heroku仪表板中。任何帮助都会得到真正的赞赏，我希望能够用它来作为即将到来的项目的一个概念证明，但是我已经完全用这个来打了一堵墙！Heroku上的Rails：ActiveRecord :: StatementInvalid，重置和迁移不起作用

的ActiveRecord :: StatementInvalid（PGError：ERROR：关系“上岗”不存在

我建立的应用程序基于博客的教程，并能正常工作，从那以后，我增加了其他2个表（以下等？教程），并设置其采用引入nokogiri耙的任务，但我不明白怎么会已经打破了链接到posts表

你正在使用PostgreSQL在Heroku的，所以你必须改变你的config/database.yml文件作为

production: 
    adapter: PostgreSQL 
    database: production 
    pool: 5 
    timeout: 5000

，并再次迁移之后通过

1)heroku run rake db:reset 
2) heroku run rake db:migrate 
3)heroku restart 
4)heroku open

在您的生产组中添加宝石

group :production do 
    gem 'thin' 
end

嗨，感谢您的帮助，我读过那个heroku忽略了database.yml无论如何，所以我没有尝试过，但现在尝试了它，推动并重新启动，但不幸仍然得到同样的问题。 – iammarkhammond 2013-05-08 11:08:00

迁移后，你尝试heroku重新启动 – Shrikant1712 2013-05-08 11:42:25

我刚刚编辑我的帖子看到它 – Shrikant1712 2013-05-08 11:46:51

Heroku上的Rails：ActiveRecord :: StatementInvalid，重置和迁移不起作用
