Hartl的铁轨教程完成了当地完美的作品。 Heroku坚持说：“我们很抱歉，但出了问题。”

[weixin_38078903]

我是Ruby on Rails的新手（完全是编程的新手），这是我第一篇关于堆栈溢出的文章。我想先感谢大家，因为我从以前的帖子中学到了很多东西。 我完成了Micheal Hartl Ruby on Rails教程，但无法在Heroku上成功启动它，即使它在本地完美工作。 ㈣完成了下列： GIT中推 GIT中推heroku上主 Heroku的PG：复位DATABASE heroku上运行耙分贝：迁移 heroku上运行耙db：填充 （我也做这个没有Heroku的重启有相同的结果） 出问题的时候我瓶坯命令：Heroku的运行耙分贝：填充 ，这里是我的Heroku登录 2013-04-23T18:27:42.388610+00:00 heroku[web.1]: Error R12 (Exit timeout) -> At least one process failed to exit

听起来像你没有加载模式到你的heroku数据库。部署后会发生什么，当你做到这一点： heroku run rake db:schema:load 注意，有时如果你加载了具有已经建立的架构一个新的应用程序，运行所有的迁移不是得到数据库的最好方式到你想要的状态 - 你应该使用rake db:schema:load来代替。让我知道这是否让你的数据库正确。 它运行后，您可以使用heroku run console然后执行控制台命令状User.all以确保它知道users表存在等 不要忘记装载模式，或运行db:migrate后重新启动服务器。对于heroku：heroku restart
