I have tried so many guides and so many tutorials, but whenever I try to retrieve information that Omniauth is supposed to provide after the user accepts the permissions. Right now I just want a user to log in with Google and access his calendar.
routes.rb
devise_for :users, path_names: {sign_in: "login", sign_out: "logout"},
:controllers => { :omniauth_callbacks => "callbacks" }
devise_scope :user do
get "/auth/google_oauth2/callback" => 'callbacks#google_oauth2'
end
config/initializes/omniauth.rb
module OmniAuth
module Strategies
class GoogleAuth < OmniAuth::Strategies::GoogleOauth2
option :name, 'google_auth'
option :callback_path, '/callbacks/google'
end
end
end
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, '<my client id in string>', '<my client secret in string>', {
access_type: 'offline',
scope: 'https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/calendar',
callback_path:'http://localhost:3000/auth/google_oauth2/callback'
prompt: 'select_account consent'
}
#provider :devloper unless Rails.env.production?
provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET']
end
callbacks_controller.rb
class CallbacksController < Devise::OmniauthCallbacksController
def google_oauth2
#user = User.from_omniauth(request.env["omniauth.auth"])
if user.persisted?
sign_in_and_redirect #user
else
session["devise.google_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
end
models/user.rb:
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.provider = auth.provider
user.uid = auth.uid
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
end
end
The error this that env["omniauth.auth"] and :provider. How do I change my files so that Omniauth correctly populates with the user's information and so that I can create a devise user for that session. The project is at https://github.com/SafaTinaztepe/teemvu.git.
on your user.rb, I think it should be
user.provider = auth['provider'],
user.uid = auth['uid'],
....

I have a rails app where users can log through facebook with oauth.
I retrieve their image, email and name. What I'd like to do is scrap their profile link (http://facebook.com/name) and gender (male,female, other)
But It doesn't work for link and gender, here is my integration:
Gemfile
gem 'omniauth-facebook'
User.rb model
def self.from_omniauth(auth)
where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
user.email = auth.info.email
user.password = Devise.friendly_token[0,20]
user.name = auth.info.name # assuming the user model has a name
user.image = auth.info.image # assuming the user model has an image
user.gender = auth.info.gender # assuming the user model has a gender
user.link = auth.info.link # assuming the user modal has a link
end
end
def self.new_with_session(params, session)
super.tap do |user|
if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"]
user.email = data["email"] if user.email.blank?
end
end
end
EDIT
devise.rb
config.omniauth :facebook, "***", "***"
But for all users, gender and link return 'nil'
Any ideas what I could be missing ?
Thanks
The url parameter doesn't work now, the correct name of the field is link
config.omniauth :facebook, 'APP_ID', 'APP_SECRET', {scope: 'email', info_fields: 'email,name,verified,gender,link'}
There is a list of attributes we can get from Facebook:
https://developers.facebook.com/docs/facebook-login/permissions/v2.5#reference-public_profile
https://developers.facebook.com/docs/graph-api/reference/user
You need to specify the scope and fields you want to get when you specify the provider in config/initializers/devise.rb
I.e.:
config.omniauth :facebook, 'APP_ID', 'APP_SECRET', {scope: 'email', info_fields: 'email,name,verified,gender,url'}
Whether or not facebook will give you all the data you ask for is a different question.
Very simple question.
I have run into the "Email can't be blank" issue with my rails app/omniauth/facebook login. There are many questions on this, and among the answers is that some users give their telephone number and not their email addresses. However in my case, I have a facebook account open, with an email address that works fine with omniauth in development, but when I use it production it comes back email can't be blank. My credentials are correct.
Can anyone explain how you could have this combination of events?
edit: here is my controller code (keep in mind my devise model is "Member" and there is an associated profile model "User"
def provider
auth = request.env["omniauth.auth"]
member_email_check = Member.find_by_email(auth.info.email)
if member_email_check.present? && User.find_by_member_id(member_email_check.id)
sign_in_and_redirect member_email_check
return false
else
member = Member.where(provider: auth.provider, uid: auth.uid).first_or_create do |member|
member.provider = auth.provider
member.uid = auth.uid
member.email = auth.info.email
end
end
if auth.provider == "facebook"
if member.save
unless User.find_by_member_id(member.id)
User.create(:member_id => member.id,
:full_name => auth.info.first_name + " " + auth.info.last_name,
:first_name => auth.info.first_name,
:last_name => auth.info.last_name,
:email => auth.info.email,
:picture => auth.info.image)
end
sign_in_and_redirect member
else
session["devise.member_attributes"] = member.attributes
redirect_to new_member_registration_url
end
end
end
alias_method :facebook, :provider
end
SOLVED!
config.omniauth :facebook, "<YOUR API KEY>", "<YOUR SECRET KEY>", scope: 'email', info_fields: 'email,name,first_name,last_name,gender'
just added the email scope and info_fields.
I have been using omniauth, based off of tutorials similar to this: https://coderwall.com/p/bsfitw#
In this tutorial, and many others, you are instructed to find a user matching what you get back from omniauth, usually like so
class SessionsController < ApplicationController
def create
user = User.from_omniauth(env["omniauth.auth"])
session[:user_id] = user.id
redirect_to root_url
end
end
class User < ActiveRecord::Base
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
end
So... what is to stop someone else from just posting :provider => "twitter", :uid => "Someone elses uid" to log in as them?
So after talking to a couple people, it appears the reason is because the omniauth.auth variables are passed via environment variables set by the omniauth middleware, not passed in directly from the request.
I have spent days watching the RailsCasts on devise and omniauth and then going through related tutorials for setting up an authentication system that uses these gems. I think the RailsCasts are out of date and trying to patch the gaps with other tutorials is creating all kinds of issues.
Please can anyone suggest a current tutorial that I can use as a basis for implementing this system. I have separate user and authentications models (with users having many authentications).
I'd really like to use devise and omniauth (with CanCan for abilities) on rails 4 but am tearing my hair out in trying to find a basic setup (using psql as a database).
To use Devise with multiple auth providers you need 1 more model - Authorization
#authorization.rb
# == Schema Information
#
# Table name: authorizations
#
# id :integer not null, primary key
# user_id :integer
# provider :string(255)
# uid :string(255)
# token :string(255)
# secret :string(255)
# created_at :datetime
# updated_at :datetime
# profile_page :string(255)
#
class Authorization < ActiveRecord::Base
belongs_to :user
end
There is code for User model
#user.rb
SOCIALS = {
facebook: 'Facebook',
google_oauth2: 'Google',
linkedin: 'Linkedin'
}
has_many :authorizations
def self.from_omniauth(auth, current_user)
authorization = Authorization.where(:provider => auth.provider, :uid => auth.uid.to_s,
:token => auth.credentials.token,
:secret => auth.credentials.secret).first_or_initialize
authorization.profile_page = auth.info.urls.first.last unless authorization.persisted?
if authorization.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
authorization.user = user
authorization.save
end
authorization.user
end
def fetch_details(auth)
self.name = auth.info.name
self.email = auth.info.email
self.photo = URI.parse(auth.info.image)
end
And at the end you need to override methods for Devise controller
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
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 first_login_path
else
redirect_to cabinet_path
end
else
session['devise.user_attributes'] = user.attributes
redirect_to new_user_registration_url
end
end
User::SOCIALS.each do |k, _|
alias_method k, :all
end
end
If you need some for providers, e.g. Twitter you need to override twitter method, because it doesn't provide user email and you should save it's credentails in some other way.
Also you should make some changes in routes
devise_for :users,
:controllers => {
:omniauth_callbacks => 'users/omniauth_callbacks',
}
in you initializers try doing something like this
#config/initializers/devise.rb
#provider1
config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_SECRET'],
:site => 'https://graph.facebook.com/',
:authorize_path => '/oauth/authorize',
:access_token_path => '/oauth/access_token',
:scope => 'email, user_birthday, read_stream, read_friendlists, read_insights, read_mailbox, read_requests, xmpp_login, user_online_presence, friends_online_presence, ads_management, create_event, manage_friendlists, manage_notifications, publish_actions, publish_stream, rsvp_event, user_about_me, user_activities, user_birthday, user_checkins, user_education_history, user_events, user_groups, user_hometown, user_interests, user_likes, user_location, user_notes, user_photos, user_questions, user_relationships, user_relationship_details, user_religion_politics, user_status, user_subscriptions, user_videos, user_website, user_work_history'
#provider2
config.omniauth :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET'],
:scope => {
:secure_image_url => 'true',
:image_size => 'original',
:authorize_params => {
:force_login => 'true'
}
}
#provider3
config.omniauth :google_oauth2, ENV["GOOGLE_KEY"], ENV["GOOGLE_SECRET"]
You should give this gem a try.

Quick and Easy to integrate. I had a working setup in about 30m.
I'm using:
Ruby on Rails 4
devise 3.0.3
omniauth (1.1.4)
omniauth-facebook (1.4.1)
omniauth-twitter (1.0.0)
I recently set up my omniauth-facebook and everything works fine. Now i want to add omniauth-twitter but somehow i mess things up, pretty bad.
1.) To set up my Omniauth-Facebook i did this (in a nutshell):
gem 'omniauth'
gem 'omniauth-facebook'
2.) Added the columns "provider" and "uid" to my User model.
3.) Next, i declared the provider in my config/initializers/devise.rb:
require "omniauth-facebook"
config.omniauth :facebook, "App_ID", "App_Secret",
{:scope => 'email,offline_access',
:client_options => {:ssl => {:ca_file => 'lib/assets/cacert.pem'}},
:strategy_class => OmniAuth::Strategies::Facebook}
4.) I edited my Model User.rb
# Facebook Settings
def self.find_for_facebook_oauth(auth, signed_in_resource = nil)
user = User.where(provider: auth.provider, uid: auth.uid).first
if user.present?
user
else
user = User.create(first_name:auth.extra.raw_info.first_name,
last_name:auth.extra.raw_info.last_name,
facebook_link:auth.extra.raw_info.link,
user_name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email,
password:Devise.friendly_token[0,20])
end
end
and added the attributes to devise:
:omniauth_providers => [:facebook]
5.) I edited the routes:
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
THE END
Although this worked perfectly for Facebook, i tried for hours now to get this working for Twitter, and i just cant figure it out.
If someone, who has experience in this, or just knows the solution could help me set this up, i would be very thankful :)
Thank you guys, and sorry for the long Post.
In Addition
Twitter does not provide an :email Attribute so i have to Split up my User Registration Process i guess ?
My Twitter action in my User Model
# Twitter Settings
def self.find_for_twitter_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth[:provider], :uid => auth[:uid]).first
unless user
user = User.create(:first_name => auth[:name],
:user_name => auth[:screen_name],
:provider => auth[:provider], :uid => auth[:uid],
:password => Devise.friendly_token[0,20]
)
end
user
end
# build auth cookie hash for twitter
def self.build_twitter_auth_cookie_hash data
{
:provider => data.provider, :uid => data.uid.to_i,
:access_token => data.credentials.token, :access_secret => data.credentials.secret,
:first_name => data.name, :user_name => data.screen_name,
}
end
I had to migrate a confirmable for Users -> How To: Add :confirmable to Users
My Form's Problem, (At Least im getting to this poing now :) )
To fix your problem with the email you could just set a dummy mail, or add a second step where the user adds his/her email.
Dummy mail:
class User < ActiveRecord::Base
before_create :set_dummy_mail, if self.provider == "twitter"
private
def set_dummy_mail
self.email = "#{self.name}_email#example.com"
end
end
Or the second step option:
Modify your controller to redirect to an add email step if the provider is twitter and the email is blank. Maybe you also have to modify your validations to allow email blank on create if the provider is twitter.
UPDATE: I did it like following:
Gemfile:
gem "devise"
gem "omniauth"
gem "omniauth-facebook"
gem "omniauth-twitter"
I used:
devise version 2.2.3
omniauth 1.1.4
omniauth-facebook 1.3.0
omniauth-twitter 0.0.17
If you are using different versions, you maybe must change a few things..
routes.rb:
devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" }
devise_scope :user do
post "account/create" => "users/accounts#create"
end

class User < ActiveRecord::Base
# allow email blank for first create
validates_format_of :email, :with => Devise.email_regexp, :allow_blank => true, :if => :email_changed?
# facebook find method
def self.find_for_facebook_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth.provider, :uid => auth.uid).first
unless user
user = User.create(:first_name => auth.extra.raw_info.first_name,
:last_name => auth.extra.raw_info.last_name,
:facebook_link => auth.extra.raw_info.link,
:user_name => auth.extra.raw_info.name
:provider => auth.provider,
:uid => auth.uid, :email => auth.info.email,
:password => Devise.friendly_token[0,20]
)
user.confirm!
end
user
end
# twitter find method
def self.find_for_twitter_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth[:provider], :uid => auth[:uid]).first
unless user
user = User.create(:first_name => auth[:first_name], :user_name => auth[:user_name],
:provider => auth[:provider], :uid => auth[:uid],

end
user

end
end

end
end
Maybe you have to modify the one or other part of my solution..you also could refactor the two methods in the user model (find_for_facebook_auth, find_for_twitter_auth) to work with one dynamic method. Try it out and let me know, if you still have problems. If you find any typo, please also let me know.. Also you should write tests to check everything within your system.
Add this in gem file
gem 'omniauth-twitter'
do bundle and restart the server
after this add your app_id and secret key in config/initializer/devise.rb
require "omniauth-twitter"
config.omniauth :twitter, "app_id", "secret_key"
edit your user model
:omniauth_providers => [:facebook,:twitter]
def self.find_for_twitter_oauth(auth, signed_in_resource=nil)
user = User.where(:provider => auth.provider, :uid => auth.uid).first
unless user
user = User.create(name:auth.extra.raw_info.name,
provider:auth.provider,
uid:auth.uid,
email:auth.info.email,
password:Devise.friendly_token[0,20]
)
end
user
end
Add new controller file in
app/controller/user/omniauth_callbacks_controller.rb
def twitter
#user = User.find_for_twitter_oauth(request.env["omniauth.auth"], current_user)
if #user.persisted?
sign_in_and_redirect #user, :event => :authentication #this will throw if #user is not activated
set_flash_message(:notice, :success, :kind => "Twitter") if is_navigational_format?
else
session["devise.twitter_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
Add this link in your view file
<%= link_to 'sign in with twitter', user_omniauth_authorize_path(:twitter) %>
Changes required in user model as twitter do not return user's email id:
Create a migration file to allow null values in user's email column:
class ChangeEmailToNullInUser < ActiveRecord::Migration
def up
change_column :users, :email, :string, :null=>true
end
def down
end
end
after this you also need to override user model validations so add this in user.rb
def email_required?
false
end
Note: Before performing this you should create your app on twitter and give proper callback path. Its is important as after authentication from twitter the controller would come back to the path which you specify in your app on twitter.
let me know if you have any problem.
Mattherick has a good solution for the email but I couldn't get the before_create to work. A callback doesn't play nice with conditional if statements because anything after the comma is meant to be an options hash. Therefore:
before_save :set_dummy_email, if self.provider == "twitter"
Popped me errors.
This how I fixed this:
before_save :set_dummy_email
def set_dummy_email
self.email ||= "#{self.name}-CHANGEME#example.com"
end
This will only set an email if one is not given by the provider (ie: Twitter).
And then for a more 'universal' way of setting attributes (so you don't need a unique strategy:
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
user.name = auth.info.name || auth.info.nickname
user.provider = auth.provider
user.uid = auth.uid
user.email = auth.info.email if auth.info.email
user.save
end
end
