Instance Method Details
#hash_accessor(hash_name, method_name, options = {}) ⇒ Object
valid options: :default - if undefined, this plugin will create an empty instance of the defined type or null :type - defaults to :string. Can also be :integer, :float, :boolean, or :array
for arrays only: :collects - only runs on arrays. Calls the lambda method on each item in the array before saving :reject_blanks - removes all blank elements after the collect method
