Question

推送到Heroku后的某个时候，我的应用程序崩溃了。

使用Heroku的回滚功能，我找到了最近的工作提交。

但是，当我恢复它时，应用程序仍然崩溃。

错误是数据库没有指定适配器 - 但在db配置文件中没有更改...

这可能是由于有缺陷的宝石更新造成的吗？反正有没有回到之前版本的gem版本？

Answer 1

由于Heroku创建了config/database.yml文件，覆盖了项目中可能存在的文件，因此排除故障有点困难。

我的猜测是配置变量（可能DATABASE_URL）已更改，新值包含无效字符或以某种方式格式错误。当您回滚Heroku应用程序时，它还会回滚配置变量更改。您仍然可以在应用历史记录中看到变量更改。

Answer 2

以下是指向答案的帖子的链接：

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

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

哪个gem更新崩溃了heroku部署？
