I am trying (again) to set up authentications with Rails 4, devise and omniauth.
I tried to follow the example in this post: Rails 4, Devise, Omniauth (with multiple providers)
I have these gems installed:
gem 'devise'
gem 'omniauth-google-oauth2'
gem 'omniauth-facebook'
gem 'omniauth-twitter'
gem 'omniauth-linkedin-oauth2'
gem 'oauth2'
I have a user model, and an authentications model.
I have:
User.rb:
has_many :authentications
def disapprove
self.approved = false
end
def approve
self.approved = true
end
SOCIALS = { facebook: 'Facebook', google_oauth2: 'Google', linkedin: 'Linkedin' }
def self.from_omniauth(auth, current_user)
authentication = Authentication.where(:provider => auth.provider,
:uid => auth.uid.to_s,
:token => auth.credentials.token,
:secret => auth.credentials.secret).first_or_initialize
authentication.profile_page = auth.info.urls.first.last unless authentication.persisted?
if authentication.user.blank?
user = current_user.nil? ? User.where('email = ?', auth['info']['email']).first : current_user
if user.blank?
user = User.new
user.skip_confirmation!
user.password = Devise.friendly_token[0, 20]
user.fetch_details(auth)
user.save
end
authentication.user = user
authentication.save
end
authentication.user
end
def fetch_details(auth)
self.first_name = auth.info.first_name
self.last_name = auth.info.last_name
self.email = auth.info.email
self.image = URI.parse(auth.info.image)
end
Authentication.rb
belongs_to :user
Routes.rb
devise_for :users,
:controllers => {
:registrations => "users/registrations",
:omniauth_callbacks => 'users/omniauth_callbacks',
}
User/registrations_controller

#before_filter :check_permissions , :only => [ :new, :create, :cancel ]

def check_permissions

end
def index
if params[:approved] == "false"
@users = User.find_all_by_approved(false)
else
@users = User.all
end
end
def create
@user = User.new(user_params) #(params[:user])
respond_to do |format|
if resource.save
# Tell the UserMailer to send a welcome email after save
# {@user.send_admin_mail
# @user.send_user_welcome_mail}
format.html { redirect_to(profile_path(@user.profile))}
#, notice: 'We have received your registration. We will be in touch shortly.') }
#format.json { render json: root_path, status: :created, location: @user }
else
#format.html { redirect_to(root_path, alert: 'Sorry! There was a problem with your registration. Please contact us to sort it out.') }
format.html { render action: 'new' }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
private
def user_params
params.require(:user).permit(:first_name, :last_name, :email, :password )
end
# protected
# def after_sign_up_path_for(resource)
# 'subscribers/new'
# end
end
User/Omniauth_callbacks controller
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
# try again following https://stackoverflow.com/questions/21249749/rails-4-devise-omniauth-with-multiple-providers
def all
user = User.from_omniauth(env['omniauth.auth'], current_user)
if user.persisted?
sign_in user
flash[:notice] = t('devise.omniauth_callbacks.success', :kind => User::SOCIALS[params[:action].to_sym])
if user.sign_in_count == 1
redirect_to profile_path(@user.profile)
else
redirect_to root_path
end
else
session['devise.user_attributes'] = user.attributes
redirect_to root_path
end
end
User::SOCIALS.each do |k, _|
alias_method k, :all
end
end
The devise/new registrations view says:

<div class="form-actions">

</div>
<% end %>
</div>
</div>
I have another model called profile.rb.
profile belongs_to user
Problems:
- None of this works. When I click on each of the social media login links, the page just jumps to the sign up by email form.
The heroku logs error message says:
(facebook) Authentication failure! invalid_credentials: OAuth2::Error, :
2015-11-03T07:05:48.237549+00:00 app[web.1]: {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"HD3mnzmSTEw"}}
- When I complete the sign up by email form with an email and password, the user name is recognised (in that the navbar says Hello , but when I go into the rails console, the user is not listed.
Also, when I click on the user name, I get an error which says that profile does not exist. The heroku logs say:
(Couldn't find Profile with 'id'=3)
- Is there another step required to make the social media registrations work to create a new user?
MY NEXT ATTEMPT:
I've changed all of the above and tried again, following the approach in the Railscasts videos.
I now use a user model and an authentications model.
In the user.rb, I have:
has_many :authentications, :dependent => :delete_all
def apply_omniauth(omniauth)
authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => auth['credentials']['token'])
end
authentication.rb
belongs_to :user
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do | user |
authentication.provider = auth.provider
authentication.uid = auth.uid
authentication.user.first_name = auth.first_name
authentication.user.last_name = auth.last_name
authentication.user.image = auth.info.image
end
end
Authentications_controller:
class AuthenticationsController < ApplicationController
before_action :set_authentication, only: [:destroy]
def index
@authentications = current_user.authentications if current_user
end
def create
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
if authentication
sign_in_and_redirect_user(:user, authentication.user.profile)
elsif current_user
current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
redirect_to user.profile_url
else
user = User.new
user.omniauth(omniauth)
if user.save!
sign_in_and_redirect_user(:user, user.profile)
else
session[:omniauth] = omniauth.except('extra')
redirect_to new_user_registration_url
end
end
end
def destroy
@authentication.destroy
respond_to do |format|
format.html { redirect_to authentications_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_authentication
@authentication = current_user.authentications.find(params[:id])
end
end
In the routes.rb, I have:
devise_for :users,
:controllers => {
:registrations => "users/registrations",
}
patch '/auth/:provider/callback' => 'authentications#create'
Omniauth.rb
require 'omniauth-facebook' require 'omniauth-google-oauth2'
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, ENV['FACEBOOK_ID'], ENV['FACEBOOK_KEY'],
:scope => 'public_profile', info_fields: 'id,first_name,last_name,link,email',
:display => 'popup',
:client_options => {:ssl => {:ca_file => '/usr/lib/ssl/certs/ca-certificates.crt'}}
Then when I try this, I get this error:
(facebook) Authentication failure! invalid_credentials: OAuth2::Error, :
2015-11-05T06:4839+00:00 app[web.1]: {"error":{"message":"Error validating verification code. Please make sure your redirect_uri is identical to the one you used in the OAuth dialog request","type":"OAuthException","code":100,"fbtrace_id":"CrvXN22Z"}}
I find the next part of the error message odd because it refers to the callbacks controller which I no longer use (the whole thing is commented out and there is no route for it).
Authentication failure! invalid_credentials: OAuth2::Error, :
2015-11-05T08:24:16.010951+00:00 app[web.1]: Processing by Devise::OmniauthCallbacksController#failure as HTML

A FURTHER ATTEMPT
I have been trying to set up devise with omniauth for more than 1.5 years now. This is my latest attempt (following the Sitepoint tutorial at sitepoint.com/rails-authentication-oauth-2-0-omniauth). I've tried to use this tutorial before and not had any success, so I've made some tweaks to try and adapt it to some aspects of other tutorials on this topic.
I now have:
user.rb
has_many :authentications, :dependent => :delete_all
def apply_omniauth(omniauth)
authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid'], :token => auth['credentials']['token'])
end
authentication.rb
belongs_to :user
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_create do | user |
authentication.provider = auth.provider
authentication.uid = auth.uid
authentication.user.first_name = auth.first_name
authentication.user.last_name = auth.last_name
authentication.user.image = auth.info.image
end
end
authentications controller
class AuthenticationsController < Devise::OmniauthCallbacksController
before_action :set_authentication, only: [:destroy]
def index
@authentications = current_user.authentications if current_user
end
def create
omniauth = request.env["omniauth.auth"]
authentication = Authentication.find_by_provider_and_uid(omniauth['provider'], omniauth['uid'])
if authentication
sign_in_and_redirect_user(:user, authentication.user.profile)
elsif current_user
current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
redirect_to user.profile_url
else
user = User.new
user.omniauth(omniauth)
if user.save!
sign_in_and_redirect_user(:user, user.profile)
else
session[:omniauth] = omniauth.except('extra')
redirect_to new_user_registration_url
end
end
end
def destroy
@authentication.destroy
respond_to do |format|
format.html { redirect_to authentications_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_authentication
@authentication = current_user.authentications.find(params[:id])
end
end
registrations controller
class Users::RegistrationsController < Devise::RegistrationsController
#before_filter :check_permissions , :only => [ :new, :create, :cancel ]
#skip_before_filter :require_no_authentication
# before_action :configure_permitted_parameters, if: :devise_controller? # Suggestion from Sitepoint tutorial - not currently implemented because not sure about the difference between this and set params.
def check_permissions
authorize! :create, resource
end
def index
if params[:approved] == "false"
@users = User.find_all_by_approved(false)
else
@users = User.all
end
end
def create
super
session[:omniauth] = nil unless @user.new_record?
end
# THIS IS A SUGGESTION FROM SITEPOINT TUTORIAL
# protected
# def configure_permitted_parameters
# devise_parameter_sanitizer.for(:sign_up) << [:first_name, :last_name]
# end
private
def user_params
params.require(:user).permit(:first_name, :last_name, :email, :password )
end
def build_resource(*args)
super
if session[:omniauth]
@user.apply_omniauth(session[:omniauth])
@user.valid?
end
end
end
routes
devise_for :users,
:controllers => {
:registrations => "users/registrations",
:omniauth_callbacks => "authentications"
# :omniauth_callbacks => 'users/omniauth_callbacks',
}
get '/auth/:provider/callback' => 'authentications#create'
I can check these routes with:
rake routes | grep auth
user_omniauth_authorize GET|POST /users/auth/:provider(.:format) authentications#passthru {:provider=>/facebook|linkedin|twitter|google_oauth2/}
user_omniauth_callback GET|POST /users/auth/:action/callback(.:format) authentications#:action
GET /auth/:provider/callback(.:format) authentications#create

<%- if devise_mapping.omniauthable? %>
<div class="twitterauth">
<%= link_to "Join with Twitter", user_omniauth_authorize_path(:twitter) %>
</div>
<% end -%>
I'm really not sure where this path is coming from. Not sure why it's named as it is.
new session partial in the view
<%- if devise_mapping.omniauthable? %>

Current error:

Devise comes with an out of the box solution for integration with omniuth. You can checkout these urls: 1. https://www.digitalocean.com/community/tutorials/how-to-configure-devise-and-omniauth-for-your-rails-application This one shows integration with DigitalOcean but can be extended to others. 2. https://github.com/plataformatec/devise/wiki/OmniAuth%3A-Overview This one is from devise wiki
Hope it helps
There is a gem called dom that was made exclusively to manage Devise with multiple providers. It makes things deadly simple!
Also, I think you should read these articles. I'm sure you can solve all your questions with them:
