Reusable Omniauth integration for Devise supporting multiple providers. Gives you a User model
Run the installer
rails generate devise_omniauth:install
Follow the instructions output from the installer
Install the database migrations

Mount the engine's routes in your routes.rb. Note: if you change the :as option you will need to customize the paths in the devise views (see below)
mount DeviseOmniauth::Engine => "/", :as => "devise_omniauth"
Now you can access the routes url helpers from this engine in your application using the prefix you cleared in the :as above, for instance:
Install the devise initializer
rails generate initializer devise
Open the newly created config/initializers/devise.rb and customize the following lines with your oauth settings:
config.omniauth :facebook, "[SET APP_ID HERE]", "[SET APP_SECRET HERE]"
To customize the devise views (optional):
rails generate devise:views
For each provider you want to use, add them to your config/initializers/devise.rb, for instance:
require "omniauth-facebook" config.omniauth :facebook, "APP_ID", "APP_SECRET"
Make sure your model is omniauthable (app/models/user.rb
