/model/user.rb
class User < ActiveRecord::Base
attr_accessible :name, :oauth_expires_at, :oauth_token, :provider, :uid
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
user.provider = auth.provider
user.uid = auth.uid
user.name = auth.info.name
user.oauth_token = auth.credentials.token
user.oauth_expires_at = Time.at(auth.credentials.expires_at)
user.save!
end
end
/controller/sessions_controller.rb
class SessionsController < ApplicationController
def create
user = User.from_omniauth(env["omniauth.auth"])
session[:user_id] = user.id
redirect_to root_url
end
def destroy
session[:user_id] = nil
redirect_to root_url, :notice => "Signed out!"
end
end
/config/initializer/omniauth.rb
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, '###########', '###########'
provider :linkedin, "##########", "##############", :scope =>
'r_fullprofile r_emailaddress r_network', :fields => ["id",
