哪个宝石更新崩溃heroku部署？

Question

推到Heroku后的某个时候，我的应用程序崩溃了。

使用Heroku的回滚功能，我发现最近的工作承诺。

但是，当我恢复到它，应用程序仍然崩溃。

的错误是数据库没有指定adapter--但没有在数据库配置文件更改...

难道这是由于越野车的宝石更新？无论如何回到以前版本的宝石版本？

Answer 1

这里的答案链接到一个帖子：

Database configuration does not specify adapter (Sinatra + Heroku + Activerecord)

production: url: <%= ENV['DATABASE_URL'] %>

Answer 2

由于Heroku的创建config/database.yml文件，覆盖你可能在你的项目中的一个，这是一个有点难以解决。

我的猜测是，配置变量（可能DATABASE_URL）被改变，新的价值有无效字符或以某种方式格式不正确。当您回滚Heroku应用程序时，它还会回滚配置变量更改。尽管如此，你仍然可以在应用历史中看到变化的变化。
