我是 Ruby on Rails 的新手（完全是编程新手），这是我关于堆栈溢出的第一篇文章。我要提前感谢大家，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，但无法让它在 Heroku 上成功启动，即使它在本地运行完美。

我做了以下事情：

git 推送

git push heroku 大师

heroku pg：重置数据库

heroku 运行 rake db:migrate

heroku 运行 rake db：填充

（我也这样做了，没有 heroku 重新启动，结果相同）

当我执行命令时出现问题：heroku run rake db:populate

这是我的heroku日志

在我看来，您没有将架构加载到您的 heroku 数据库中。部署后执行此操作会发生什么：

heroku run rake db:schema:load

请注意，有时如果您正在加载具有已建立架构的新应用程序，则运行所有迁移并不是使数据库达到您想要的状态的最佳方法 - 您应该rake db:schema:load改用。让我知道这是否使您的数据库正确。

运行它后，您可以使用heroku run console然后执行控制台命令，例如User.all确保它知道users表存在等。

不要忘记在加载架构或运行db:migrate. 对于heroku，那就是：heroku restart
