Devise-Neo4j Build Status

A gem for Neo4j integration with the Devise authentication framework.

Neo4j: Devise:



Add the neo4j and devise-neo4j gems to your Gemfile:

gem "neo4j"
gem "devise-neo4j"

Run the bundle install command:

bundle install

Then run the Devise install generator and optionally update or create a devise-neo4j model:

rails g devise:install --orm=neo4j
# Make sure the model file is created ahead of time!
rails g neo4j:devise MODEL  # (Where MODEL is something like User)

Add the Devise route to your config/routes.rb:

devise_for :users

Now the model is set up like a default Devise model, meaning you can do things like adding a before_action in a controller to restrict access to logged-in users only:

before_action :authenticate_<your model name>!

Example App

You can see a very simple app that demonstrates Neo4j and devise here:

gem install rails
rails new myapp -m -O
cd myapp

# Add the gem to your Gemfile, then run bundle:
gem 'devise-neo4j'

rails generate devise:install --orm=neo4j

# Install the database unless you already have a Neo4j database, or use JRuby Embedded Neo4j db
rake neo4j:install[community-2.2.2] # check which one is the latest
rake neo4j:start

rails g neo4j:devise User

# Add to your config/routes.rb:
devise_for :users
root :to => "secrets#show"

# Generate a controller for the protected content
rails g controller secrets show

# In app/controllers/secrets_controller.rb add:
before_action :authenticate_user!

# In app/views/secrets/show.html.erb add:
<p>Shhhh... this page is only visible to logged-in users!</p>
<%= link_to "Log out", destroy_user_session_path, method: :delete  %>

# Start the application and visit http://localhost:3000/users/sign_up
rails s


For JRuby

JRUby neo4j has an embedded server as part of the gem, so nothing else is needed to get set up and running.

For Ruby

There is a Vagrant setup that installs neo4j so that you can easily get started:

$ vagrant up

The neo4j web interface is forward to port 7474 on your local machine: http://localhost:7474.

Note on testing

To run all test, simply type rake If you want to run a specific Devise test (see the devise github repository) set the DEVISE_TEST_PATH.

Example: rake DEVISE_TEST_PATH=integration/confirmable_test.rb

Note on Patches/Pull Requests

  • Fork the project.
  • Make your feature addition or bug fix.
  • Add tests for it. This is important so I don't break it in a future version unintentionally.
  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
