Question

Similar to ‘rails server’ that prints every SQL query executed I would like to do the same for rake tasks.

What is the best way to achieve that?

Answer 1

Depending on your environment, Rake will log sql queries just like any Rails process will & in the same logfile. So on your dev box, check your log/development.log file – it will contain your Rake task’s queries. If you want queries logged in production, set the log level in your Rake task to DEBUG, and make sure the rake task depends on :environment.

desc "Task with SQL logging"
task :test_log => :environment do
  Rails.logger.level = Logger::DEBUG
  Your code here...
end
