Neo4j::Rails Introduction

API

The neo4j gem contains two Rails Active Model complient classes:

• Neo4j::Rails::Model
• Neo4j::Rails::Relationship

They also implements a small subset of the Active Record API. The neo4j gem uses the neo4j-core, neo4j-wrapper and the neo4j-cypher gems.

Generate a Rails Application

Example of creating an Neo4j Application from scratch: (make sure you have installed JRuby version >= 1.6.2)

 gem install rails
 rails new myapp -m http://andreasronge.github.com/neo4j/rails.rb -O
 cd myapp
 bundle
 rails generate scaffold User name:string email:string
 rails s
 open a webbrowser: http://localhost:3000/users

The -O flag above means that it will skip active record.
