This is an example Rails 3 application to login to Github using OAuth2 and Devise

For more details on Githubs OAuth2 Setup – GitHub OAuth Busy Developer’s Guide

I built this so I could learn how to use OAuth2 with Github, it provides an easy base to build your own apps

• Latest Rails 3 (GIT master)
• Latest Devise (GIT master)
• Latest OAuth2 Gem (v0.0.10)

• Clone me git clone git://github.com/lloydpick/rail3_github_oauth2_devise_example.git
• Install latest beta bundler (because Rails 3 master needs it) gem install bundler --version 1.0.0.beta.4
• Go go magic bundler bundle install
• Create and migrate the database rake db:create & rake db:migrate

Register for an application – GitHub OAuth2 Application Registration – and fill in the form…

Name: My Super Cool App (Development)
Main URL: http://localhost:8080
Callback URL: http://localhost:8080/users/oauth2

Put the Client ID and Secret codes into the config/oauth2_config.yml file. By default this will have the
authorize_path and access_token_path setup correctly for Github Auth.

Then just boot up the app with the server of your choice and click the “Sign in with Github” link. It should
take you off to Github, ask you to authorize, then back to your app, creating a devise user, and logging you in.

While testing it helps to know where you can see all your OAuth2 applications this can be found here on github…

If you need to see or delete your OAuth2 connections for your GitHub account you can do that here…
