If you write the following code in your environment file, it should work.

if "irb" == $0
  config.logger = Logger.new(Rails.root.join('path_to_log_file.txt'))
end

You can also rotate the log file using

config.logger = Logger.new(Rails.root.join('path_to_log_file.txt'), number_of_files, file_roation_size_threshold)

For logging only active record related operations, you can do

ActiveRecord::Base.logger = Logger.new(Rails.root.join('path_to_log_file.txt'))

This also lets you have different logger config/file for different environments.
