Heroku App总是崩溃

Question

自从我的heroku应用程序开始崩溃以来,现在已经过了48个小时.我真的不知道是什么让它崩溃了,我已经尝试重新启动它,更改动力学和跑步heroku run rake db:migrate但这些似乎都不起作用.

这些是我的heroku日志

我已经尝试过更改为2 Dynos x1和1 Dyno x2,但它并没有改变我安装的PostgreSQL Crane并设置为我的DATABASE_URL.

它为什么会崩溃,我怎么能解决这个恼人的错误？

谢谢

看起来你的应用程序反复崩溃(但你已经知道了).您是否创建了尚未运行的迁移？

试试heroku run bundle exec rake db:migrate.

如果这不起作用,请尝试在Heroku上运行Rails控制台以帮助诊断问题.跑heroku run bundle exec rails console.
