Introduction
Neo4j.rb is an Active Model compliant Ruby/JRuby wrapper for the Neo4j graph database. It uses the neo4j-ruby-driver and active_attr gems.
Neo4j is a transactional, open-source graph database. A graph database manages data in a connected data structure, capable of representing any kind of data in a very accessible way. Information is stored in nodes and relationships connecting them, both of which can have arbitrary properties. To learn more visit What is a Graph Database?
With this gem you not only do you get a convenient higher level wrapper around Neo4j, but you have access to a powerful high-level query building interface which lets you take advantage of the power of Neo4j like this:
# Break down the top countries where friends' favorite beers come from
person.friends.favorite_beers.country_of_origin(:country).
order('count(country) DESC').
pluck(:country, count: 'count(country)')
It can be installed in your Gemfile
with a simple gem 'neo4j'
