Module: DelegateMissingTo

Extended by:

ActiveSupport::Concern

Included in:

Overview

Delegates missing methods to another object(s). May be useful for inheritance mechanisms, decorator pattern or graceful object replacement for refactoring.

Example with delegation of missing methods to an association:

class A < ActiveRecord::Base
  def qwe
    123
  end
end

class B < ActiveRecord::Base
  include ActiveRecord::DelegateMissingTo

  belongs_to :a
  delegate_missing_to :a
end

b = B.new
b.qwe # => 123

Additionally you may specify a delegation chain:

delegate_missing_to :first_priority, :second_priority, :third_priority
