rails api 在 heroku 上

Question

我使用 rails-api 构建了一个仅 api 的 rails 应用程序。它在本地效果很好。但是，当我将它部署到 heroku 时，它会产生错误 We're sorry, but something went wrong. If you are the application owner check the logs for more information..

然后我在 CLI 中使用命令 heroku logs 检查了日志：

但是我在日志中没有看到任何错误，你能帮我解决一下吗？谢谢。

Answer 1

您可以按Cntrl+F 然后搜索错误。您列出的代码不包含任何错误。

但是如果它在本地工作但在 Heroku 中不工作，你可能忘记了运行

heroku run rake db:migrate

or

heroku run rake db:seed

rails api 在 heroku 上

rails api on heroku

ruby-on-rails

heroku
