class Person
  include ActiveModel::Model
  include GlobalID::Identification

  attr_accessor :id

  def self.find(id)
    new id: id
  end

  def ==(other)
    id == other.try(:id)
  end
end

person_gid = Person.find(1).to_global_id
# => #<GlobalID ...
person_gid.uri
# => #<URI ...
person_gid.to_s
# => "gid://app/Person/1"
GlobalID::Locator.locate person_gid
