轨4.2无法看到的Heroku的数据库查询记录，即使LOG_LEVEL设置为：调试

Question

这里是一个项目，我的工作：https://github.com/homanchou/the_drawing_challenge

我无法看到所有的数据库查询服务器登录在运行彪马工头时，甚至可以在终端本地。

所有我看到的是资产或Web请求

21:54:34 web.1 | started with pid 54784 
21:54:35 web.1 | [54784] Puma starting in cluster mode...

我只好到另一行添加到Procfile log: tail -f -n 0 log/development.log看到的foreman start标准输出日志或错误，像我通常做，但只能在本地，而不是在heroku上，除非我想扩大拖尾的过程。

在我的其他轨道项目中，我可以看到的数据库查询罚款，甚至在Heroku上我可以看到日志中的数据库查询：

2015-04-03T03:46:40.052067+00:00 app[web.1]: Started GET "/api/notifications/unread_count" for 97.93.34.8 at 2015-04-03 03:46:40 +0000

我试图比较两个甚至复制了一些环境配置，但我仍然无法弄清楚。我试过在生产环境中设置config.log_level =：debug。我可以在ruby控制台中看到db查询，但不能在终端中看到heroku或本地puma标准输出。我错过了什么？

如果你需要使用的PUMA等的WebSockets尝试添加

ActiveRecord::Base.logger.level = Logger::DEBUG 

您environments.rb或环境/生产
