virtus_anonymous_embedded_value.rb

class User
  include Virtus

  attribute :address do
    attribute :street,  String
    attribute :city,    String
    attribute :zipcode, String
  end
end

# or maybe

class User
  include Virtus

  embed :address do
    attribute :street,  String
    attribute :city,    String
    attribute :zipcode, String
  end
end

user = User.new(:address => { :street => 'Foo', :city => 'Bar', :zipcode => '1234' })

or ever attr_embed? Hard choice anyway. No OK I don't like attr_embed :) It's definitely an hard choice :)

@lucapette to be honest I don't like "attr" abbreviation in general :) embed sounds/looks good IMHO

@solnic Yeah I know. You're right ;) I've update the comment just after I've done it
