Module: Distribunaut::Distributable

Defined in:
lib/distribunaut/distributable.rb

Overview

Include this module into any class it will instantly register that class with the distribunaut_ring_server. The class will be registered with the name of the class and the distribunaut.distributed_app_name configured in your config/configatron/*.rb file. If the distribunaut.distributed_app_name configuration parameter is nil it will raise an Distribunaut::Distributed::Errors::ApplicationNameUndefined exception.

Example:

class User
  include Distribunaut::Distributable
  def name
    "mark"
  end
end

Distribunaut::Distributed::User.new.name # => "mark"
