Overview

Active Model Date Type

::ActiveModel::Attribute type for date representation. It is registered under the :date key.

class Person
  include ActiveModel::Attributes

  attribute :birthday, :date
end

person = Person.new
person.birthday = "1989-07-13"

person.birthday.class # => Date
person.birthday.year  # => 1989
person.birthday.month # => 7
person.birthday.day   # => 13

String values are parsed using the ISO 8601 date format. Any other values are cast using their to_date method, if it exists.
