如何在Rails服务器控制台中显示SQL查询的来源？

Question

In development mode, I would like to be able to see in the console where an SQL query was fired.

What is currently showing up in my console (dumb example query)

User Load (1.7ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 65 LIMIT 1

What I would like to see

application_controller.rb:68
User Load (1.7ms)  SELECT `users`.* FROM `users` WHERE `users`.`id` = 65 LIMIT 1

Answer 1

检出https://github.com/RISCfuture/sql_origin以获取提供该功能的gem。

Answer 2

对于未来的Google员工：gem active_record_query_trace也可以做到这一点，甚至更多。
