PaperBoy

Automatically deliver notifications to subscribers from controllers (lightweight mixin using ActiveSupport::Notifications)

Add this line to your application's Gemfile:

gem 'paper_boy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paper_boy

At first, execute install command:

$ bin/rails g paper_boy:install

Include PaperBoy in ApplicationController:

class ApplicationController < ActionController::Base
  include PaperBoy
end

And you generate subscriber class with generator command:

$ bin/rails g paper_boy:subscriber

Then you implement app/subscribers/users_subscriber.rb:

class UsersSubscriber < ApplicationSubscriber
  def create(event)
    payload = event.payload

    # All instance variables are set from controller class.
    user = payload[:current_user]

    # implement something (mailer, notifier, logger ...etc)
    logger.info user
  end

  attach_to :"users"
end
