Ruby on Rails SQL记录

Question

Is it possible in Ruby on Rails to log only the SQL commands generated and save it on a separate file?

I'm still in development mode and looking to save all the SQL commands on a seperate log.

I've checked the development.log files but they also save data like the

"Started GET "/assets/application.css" for 127.0.0.1 at 2014-02-17 16:41:47 +0800, etc.

I am looking to either create a separate log file only for SQL or remove these other lines leaving only the SQL commands.

Is this possible? Thank you.

如果您使用活动记录，则可以覆盖活动记录记录器：

ActiveRecord::Base.logger = Logger.new("#{Rails.root}/log/sql_log.log")
