Gitkeeper for Rails 4.1.0¶ ↑

First register your app on GitHub

https://github.com/settings/applications/new

Name

localhost

URL

http://localhost:3000/

Callback URL

http://localhost:3000/auth/github/callback

Set environment variables for your local OS ( follow Linux/bash export )

export GITHUB_KEY=put-your-Client-ID-here
export GITHUB_SECRET=put-your-Client-Secret-here

Now create a brand new rails app. Please note we do skip Test::Unit files, skip Active Record files and we don’t run bundle install.

rails new host_app -T -O -B

Change directory to host_app

cd host_app

Add mongoid (4.0.0) for rails 4.1.0

echo "gem 'mongoid', :git => 'git://github.com/mongoid/mongoid.git'" >> Gemfile

Include the engine in your app

echo "gem 'gitkeeper'" >> Gemfile
bundle install

Mount the engine adding the following to config/routes.rb

HostApp::Application.routes.draw do
  mount Gitkeeper::Engine => "/auth"
end

Config mongoid ( host_app/config/mongoid.yml ) and start MongoDB

development:
  sessions:
    default:
      database: gitkeeper_dev
      hosts:
        - localhost:27017

Run the server

rails s

Visit the following URL

http://localhost:3000/auth

This is a mountable (ie, isolated) Rails engine, which has to be mounted on a new or pre-existing Rails 4.1.0 app. The User model here, is ‘name spaced’ within gitkeeper_users, as you can see from the following Rails logs :
