Examples:

using generated UUIDs

class Person
  include ActiveGraph::Node
  # creates a 'secret' neo4j property my_uuid which will be used as primary key
  id_property :my_uuid, auto: :uuid
end

using user defined ids

class Person
  include ActiveGraph::Node
  property :title
  validates :title, :presence => true
  id_property :title_id, on: :title_to_url

  def title_to_url
    self.title.urlize # uses https://github.com/cheef/string-urlize gem
  end
end

using already exsting ids that you don’t want a constraint added to

class Person
  include ActiveGraph::Node
  property :title
  validates :title, :presence => true
  id_property :id, on: :id_builder, constraint: false

  def id_builder
    # only need to fill this out if you're gonna write to the db
  end
end
