module DelegateMissingTo
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
