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 and Rails Example

See kvitter

Neo4j.rb Scaffolds

For available commands for neo4j models:

rails generate model --help

Example: rails generate scaffold Post title:string --timestamps

Notice There are no configuration needed to create new model objects. The neo4j generate scaffold command only creates source code in the app/model folder.

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
Replace the line require ‘rails/all’ with:

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 or latest version'
and remove all sql gems. Install the gems specified in your Gemfile bundle install
