Always turn on ActiveRecord logging in the console

Remember that you can turn on ActiveRecord logging for the console and see what SQL-query is executed?
Here’s a statement you can put in your environment.rb file (or in one specific environment config file - such as development.rb) to have it turned on permanently:

if "irb" == $0
 ActiveRecord::Base.logger = Logger.new(STDOUT)
end
