Ruby on Rails Omniauth


First choose your auth strategy and add it to your Gemfile. You can find a list of strategies here:

gem 'omniauth-github', :github => 'intridea/omniauth-github'
gem 'omniauth-openid', :github => 'intridea/omniauth-openid'

You can add this to your rails middleware like so:

Rails.application.config.middleware.use OmniAuth::Builder do
  require 'openid/store/filesystem' 
  provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET']
  provider :openid, :store =>'/tmp')

By default, OmniAuth will add /auth/:provider to your routes and you can start by using these paths.

By default, if there is a failure, omniauth will redirect to /auth/failure
