Andreas Ronge has released Neo4j.rb version 0.0.7, which adds support for value objects and automatic engine startup and shutdown. The project allows users to use Neo4j as a complement or replacement for ActiveRecord in Ruby on Rails by simply adding the neo4j gem to the rails config/environment.rb file. An example of using a Neo4j.rb model is provided, demonstrating how to create a new node and update it with request parameters.
