puts vs logger in rails rake tasks

Put this in application.rb, or in a rake task initialize code

if defined?(Rails) && (Rails.env == 'development')
  Rails.logger = Logger.new(STDOUT)
end

This is Rails 3 code. Note that this will override logging to development.log. If you want both STDOUT and development.log you’ll need a wrapper function.

If you’d like this behaviour only in the Rails console, place the same block of code in your ~/.irbrc.
