For Rails 4 and newer, you can use Logger broadcast.
If you want to get both STDOUT and file logging for rake tasks in development mode, you can add this code into config/environments/development.rb
:
if File.basename($0) == 'rake'
# http://stackoverflow.com/questions/2246141/puts-vs-logger-in-rails-rake-tasks
log_file = Rails.root.join("log", "#{Rails.env}.log")
Rails.logger = ActiveSupport::Logger.new(log_file)
Rails.logger.extend(ActiveSupport::Logger.broadcast(ActiveSupport::Logger.new(STDOUT)))
end
Here's a small Rake task to test the above code :
# lib/tasks/stdout_and_log.rake
namespace :stdout_and_log do
desc "Test if Rails.logger outputs to STDOUT and log file"
task :test => :environment do
puts "HELLO FROM PUTS"
Rails.logger.info "HELLO FROM LOGGER"
end
end
Running rake stdout_and_log:test
outputs
HELLO FROM PUTS
HELLO FROM LOGGER
while
HELLO FROM LOGGER
has been added to log/development.log
.
Running rake stdout_and_log:test RAILS_ENV=production
outputs
HELLO FROM PUTS
while
HELLO FROM LOGGER
has been added to log/production.log
.
