I'm using Facebook Oauth and Devise in my rails app. I successfully get taken to the facebook login page, but then get an error on the callback action. Tracked it down to request.env["omniauth.auth"] returning nil in my callback action.
Gemfile:
gem 'devise' gem 'omniauth' gem 'omniauth-facebook' Routes:
devise_scope :user do get '/users/auth/facebook/callback', to: 'users/omniauth_callbacks#facebook' end resources :users devise_for :users, path: '', path_names: { sign_up: 'register', sign_in: 'login', sign_out: 'logout'}, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } initializers/devise.rb:
config.omniauth :facebook, Figaro.env.facebook_key, Figaro.env.facebook_secret, scope: 'email,public_profile', callback_url: Figaro.env.facebook_callback_url User.rb:
class User < ActiveRecord::Base devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :confirmable, :validatable, :omniauthable, :omniauth_providers => [:facebook] omniauth_callbacks_controller.rb:
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController def facebook @user = User.from_omniauth(request.env["omniauth.auth"]) request.env["omniauth.auth"] ## <<=== this is nil Any idea why my request.env["omniauth.auth"] is returning nil?

So finally i am able to find the issue, i was also struggling with the same issue for a long time, but now we have the solution, ok here we go:
The problem is with the devise.rb, just remove this from the file:
config.omniauth :facebook, Figaro.env.facebook_key, Figaro.env.facebook_secret, scope: 'email,public_profile', callback_url: Figaro.env.facebook_callback_url and then restart your server and then try to get login through facebook.
You will get what you want :)
Thanks, Enjoy Coding :)
