Question

I want to write a logging model and controller, to log everything that user does. I was thinking about creating a db table with from ip address, controller that user called, view that was displayed and params.inspect.

Is there a way to get to a variable which controller is currently being used? What is the best way to deploy this? Is out there a gem that do all this?
Thank you

If you set the log level in production to :debug then every request is logged with the information you need. Perhaps, it might be easier to write a parser for the debug production log.

If you prefer, you can also add a filter to your ApplicationController:

class ApplicationController
  before_filter :log_activity

  def log_activity
    if Rails.env == 'production'
      @logger ||= Logger.new("#{Rails.root}/log/activity.log")
      values = [
        request.remote_ip,
        controller_name,
        action_name,
        params.inspect
      ]
      @logger.info "#{values.join ' | '}"
    end
  end

  ...
end

this might not be complete as you want the output to be more verbose, but this is the idea.
