CrowdintAuth

Adds the required configuration to use Devise with our Crowd Interactive Google Apps account for authentication.

Installation

Gemfile

gem 'crowdint_auth'

Run

bundle install

Usage

Migration

Devise model needs the following extra fields:

class AddColumnsToUsers < ActiveRecord::Migration
  def change
    add_column :users, :provider, :string
    add_column :users, :uid, :string
  end
end

Devise

The devise model should include the :omniauthable option, for example:

devise :database_authenticatable, :token_authenticatable, :trackable, :omniauthable

Routes

If your user class is User

Set up the devise routes:

devise_scope :user do
  get 'google_apps_sign_in', :to => "crowdint_auth/omniauth_callbacks#google_apps_sign_in"
end

devise_for :users, controllers: { omniauth_callbacks: 'crowdint_auth/omniauth_callbacks' }

The first match will determine the url for the login. That is, your sign in link will probably look something like:

= link_to 'Sign In', google_apps_sign_in_path

If your user class is named differently

Create your own omniauth callbacks controller that inherits from CrowdintAuth::OmniauthCallbacksController:

class Users::OmniauthCallbacksController < CrowdintAuth::OmniauthCallbacksController
  def user_class
    OtherClass
  end
end

And set it up on routes:

devise_scope :user do
  get 'google_apps_sign_in', :to => "users/omniauth_callbacks#google_apps_sign_in"
end

devise_for :users, controllers: { omniauth_callbacks: 'users/omniauth_callbacks' }
