Question

我有一个rails 4应用程序，我想查看在我的应用程序中执行的sql查询。

在我的config / environment / development.rb中：

config.log_level = :debug

但是不足以显示我的rails应用程序生成的查询。

$ rails -v
Rails 4.1.1

$ ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]

当我启动rails服务器时，不显示查询。

$ rails s
=> Booting WEBrick
=> Rails 4.1.1 application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

以下是我正在寻找的一个例子：

User Load (0.003154)   SELECT * FROM `users` WHERE (`users`.`id` = 1) - (user.rb, line 24)

有人对我需要做什么有所了解？非常感谢！
