Just a quick announcement that I just pushed a new version of Virtus with support for long awaited features: EmbeddedValue, member type coercions for array/set attributes and ValueObject. Current version is 0.2.0, please give it a try and tell me what you think.

Here’s a quick sneak-preview of what you can do with Virtus:

class GeoLocation
  include Virtus::ValueObject

  attribute :lat, Float
  attribute :lng, Float
end

class City
  include Virtus

  attribute :name,      String
  attribute :location,  GeoLocation
  attribute :districts, Array[Symbol]
end

class User
  include Virtus

  attribute :name, String
  attribute :age,  Integer

  attribute :city, City
end

user = User.new(
  :name => ‘John’,
  :age  => 29,
  :city => {
    :name      => ‘NYC’,
    :location  => { :lat => ‘1234567.89’, :lng => ‘9876543.21’ },
    :districts => [ ‘one’, ‘two’, ‘three’ ]
  }
)

user.city.location.lat # => 1234567.89
user.city.districts    # => [ :one, :two, :three ]

I hope you’re going to enjoy it and find it useful in your projects. In case of any issues please report them on Github.

Huge props go to Dan Kubb, Emmanuel Gomez and Yves Senn for helping me with recent releases! Thanks guys!
