我制作了一个非常基本的RoR应用程序并部署到heroku。
进入heroku给出的网站后，我看到了这样的信息：
＆＃34;应用程序错误 应用程序中发生错误，无法提供您的页面。如果您是应用程序所有者，请检查日志以获取详细信息。＆＃34;
我尝试过 heroku restart
我得到的错误日志是：

您需要对Heroku错误H10 - App crashed进行问题排查，如果您在Heroku信息中心或计算机rails c上运行heroku run rails c，应用程序会因多种原因而崩溃，然后会出现更多特定错误ActiveRecord查询和行号有问题就像13，文件是../app/models/或类似的东西，我写了一些参考文章，为什么有时app会崩溃到Heroku。
一些可能的原因
