When do you need it?

It is very useful gem if you want to provide a system activity page inside your backend.

How to use it? Look over next chapter.

How to install and use it?

Install a gem.

sudo gem install acts_as_protocolable

Generate migration and run it.

rake db:migrate

Now a bit of configuration.

# config/environment.rb
config.gem 'acts_as_protocolable'

# app/controllers/admin/admin_controller.rb
class Admin::AdminController < ApplicationController
  before_filter :set_internal_user_id
  
  def set_internal_user_id
    ActsAsProtocolable.internal_user_id = current_user.id
  end
