And then execute:

Or install it yourself as:

$ gem install redispatcher

Using

Writing Dispatchers

Dispatchers inherit from Redispatcher::Dispatcher, live in your app/dispatchers directory, and are named for the model that they dispatch:

# app/dispatchers/topic_dispatcher.rb
class TopicDispatcher < Redispatcher::Dispatcher
end

Do not hesitate to use dispatscher's callbacks before_ and after_ initialize, process, commit, rollback just like that:

# app/dispatchers/topic_dispatcher.rb
class TopicDispatcher < Redispatcher::Dispatcher

  after_initialize do
    @processed_object = {}
  end

  before_process do
    @processed_object.merge! title: object.title
  end

  after_commit :update_mongodb

  def update_mongodb
    MONGO['topics'].update({ id: object.id }, processed_object, upsert: true)
  end
end

Enable dispatcher for your model

class Topic < ActiveRecord::Base
  dispatchable
end

Dispatch!

Just call dispatch method on object you going to dispatch.

dispatched_topic = Topic.first.dispatch
