Module: Disposable::Twin::Builder

Defined in:
lib/disposable/twin/builder.rb

Overview

Allows setting a twin class for a host object (e.g. a cell, a form, or a representer) using ::twin and imports a method #build_twin to initialize this twin.

Example:

class SongTwin < Disposable::Twin
  properties :id, :title
  option :is_released
end

class Cell
  include Disposable::Twin::Builder
  twin SongTwin

  def initialize(model, options)
    @twin = build_twin(model, options)
  end
end

An optional block passed to ::twin will be called per property yielding the Definition instance.
