def self.serialize date, options = {}
  unless date.is_a?(Date)
    raise ArgumentError, "expected a Date value, got #{date.class}"
  end
  date.strftime('%Y-%m-%d')
end

.type_cast(raw_value, options = {}) ⇒ Date?

Returns value cast to a Date object. Empty strings are cast to nil. Values are cast first to strings and then passed to Date.parse. Integers are treated as timestamps.

date_attribute.type_cast('2000-01-02T10:11:12Z')
#=> #<Date: 4903091/2,0,2299161>

date_attribute.type_cast(1306170146)
#<Date: 4911409/2,0,2299161>

date_attribute.type_cast('')
#=> nil

date_attribute.type_cast(nil)
#=> nil

Parameters:

  • raw_value (Mixed) —

    The value to cast to a Date object.

  • options (Hash) (defaults to: {})

Returns:

  • (Date, nil)
