Neo4j::Rails Scaffolds & Generators

Rails Neo4j Project Template

Make sure you are running JRuby (rvm install jruby).
Creating an Neo4j application from scratch:

gem install rails
rails new myapp -m http://andreasronge.github.com/neo4j/rails.rb
rails generate scaffold User name:string email:string
rails s

open a webbrowser: http://localhost:3000/users

The database will be stored in the db/neo4j-development folder.
To start with a fresh new database, simply delete that folder.

Neo4j.rb Scaffolds

For available commands for neo4j models:

rails generate model —help

Example:

rails generate scaffold Post title:string —timestamps

Installation and Configuration

If you don’t want to use the Neo4j Project template above you can do it yourself.

Replace ActiveRecord with Neo4j

Edit the config/application.rb
comment the line require ‘rails/all’ and add

require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie" 
require 'neo4j'

Remove all references to active record in config/application.rb and config/environment/*

Include Dependency to Neo4j

Add the following line to your Gemfile
gem 'neo4j', '2.0.0'
and remove all sql gems. Install the gems specified in your Gemfile bundle install
