Hide all Virtus attributes

gistfile1.rb

require 'virtus'

module PersonAttributes
  include Virtus.module

  attribute :name, String
  attribute :age, Integer
end

class PersonModel
  include PersonAttributes
end

class PersonDomain
  include PersonAttributes

  attribute_set.each do |att|
    # Take two approaches
    
    # Idea 1: FAIL initialize with hash sets 'nil'
    private :"#{att.name}="
    
    # Idea 2: FAIL ignored
    att.options[:writer] = :private
  end
end


person = PersonDomain.new(:name => 'John', :age => 30)
raise 'Name was not set' if person.name.nil?

begin
  person.name = 'Foo'
  raise 'Write was OK'
rescue NoMethodError
end

begin
  person.age = 31
  raise 'Write was OK'
rescue NoMethodError
end

The objective is to define a Virtus module with a set of attributes for Person

There are two type of Person objects, a PersonModel with setters and getters, and a PersonDomain where setters and getters are private (in the example just setters)
