Omniauth::MultipleProviders

Support for Omniauth and Multiple Providers.

Dependency

Devise

Omniauth::MultipleProviders requires User model and current_user helper, like Devise. You should create User model, before rails g omniauth:multiple_providers:install. ex) do rails g devise User

Omniauth and Omniauth Strategy

You should setup Omniauth configuration, before rails g omniauth:multiple_providers:install. ex) create config/initializers/omniauth.rb file.

gem 'devise'
gem 'omniauth'
gem 'omniauth-facebook' # etc you needs
gem 'omniauth-twitter'  # etc you needs

Installation

Add this line to your application's Gemfile:

gem 'omniauth'
gem 'omniauth-facebook' # etc you needs
# ...
gem 'omniauth-multiple_providers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-multiple_providers

Usage

app/models/user.rb (generated by Devise) do not use :omniauthable.

# app/models/user.rb
class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable # <= do not use
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :confirmable
  # ...
end
$ rails generate omniauth:multiple_providers:install
$ rake db:migrate # => create provider_users table

You can use new_omniauth_path(provider: :provider_name), and It redirect_to /auth/:provider_name. And automatically receive callback, and Save to ProviderUser(app/models/provider_user.rb).

%ul
  %li
    = link_to new_omniauth_path(provider: :twitter) do
      Signup with Twitter
  %li
    = link_to new_omniauth_path(provider: :facebook) do
      Signup with Facebook
  %li
    = link_to new_omniauth_path(provider: :github) do
      Signup with Github

And if you remove connection to Providers,

= link_to omniauth_path(:twitter), method: :delete do
  cancel connection

TODO

  • Drop Dependency of Devise
  • Configuratable with initializer
