I have followed https://www.digitalocean.com/community/tutorials/how-to-use-the-ruby-on-rails-one-click-application-on-digitalocean tutorial. Now all are working in good condition. But my production.log file is empty. Logs are not recording. I have applied some method to resolve this issue but I didn't get any proper solution. I have puted config/environments/production.rb, below code.
config.log_level = :debug

RAILSDEFAULTLOGGER = Logger.new('log/production.log')

But still I am facing this issue. Please help to take out of this??
