Question

所以我的主要铁路模型是“公司”。当我在本地托管我的应用程序并导航到localhost：3000 /公司时，一切正常。但是当我导航到我的应用程序的heroku版本时：

http://calm-journey-2877.herokuapp.com/companies

..我收到错误“我们很抱歉，但出了点问题”

这表明该页面存在但产生某种错误..任何想法可能会发生什么？这是我通过阅读Rails教程书而构建的一个非常基本的应用程序。

谢谢！

这是Heroku日志。

Answer 1

您是否在Heroku heroku run rake db:migrate中迁移了数据库？

Answer 2

你的解决方案在git中休息。编写你的rake任务并确保它在你的git存储库中。

比尝试 Heroku运行rake your_task

或者将您的DB种子文件用于其预期目的。

Heroku路线不起作用
