Module: HungryForm::Elements::Base::Hashable

Included in:
Element
Defined in:
lib/hungryform/elements/base/hashable.rb

Overview

This module adds hashing capabilities to form elements. Do not include this module in your classes. It is already included in the base_element class.

Sample usage:

class MyField

attr_accessor :param1, :param2
hashable :param1, :param2
...

end

Any instance of MyField class will have the “to_hash” method that will contain only the accessor/reader params defined in the hashable macro.
