I'm trying to save the name of a Facebook user upon saving that user, but I don't seem to be able to. I have followed the guides on the devise github and the integration with Facebook works fine; the users email is saved as is to be expected. However, I can't figure out how to save the users name. Right now, I do this:
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token['extra']['user_hash']
if user = User.find_by_email(data["email"])
user
else # Create a user with a stub password.
User.create(:email => data["email"], :name => data["name"], :password => Devise.friendly_token[0,20])
end
end
but that doesn't work. Am I doing something wrong?
Seems like Auth hash schema has changed a lot:
https://github.com/intridea/omniauth/wiki/Auth-Hash-Schema
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if user = User.where(:email => data.email).first
user
else
# Create a user with a stub password.
user = User.create!(:username => data.username ? data.username : data.nickname , :email => data.email, :password => Devise.friendly_token[0,20])
end
end
The users name is stored in:
auth = request.env['omniauth.auth'] #I think this is what your access_token variable equates to.
auth['user_info']['name']
If that is not what you need, I suggest you inspect the contents of the access_token.

I've gotten the omniauth to work with google by following this tutorial. The problem I'm currently having is that instead of creating the user when they sign up, I want to route them to a finish registration page where they have to enter additional data. This is similar to how pastebin handles their oauth registration.
UserModel (taken from tutorial):
def self.find_for_google_oauth2(access_token, signed_in_resource=nil)
data = access_token.info
user = User.where(:provider => access_token.provider, :uid => access_token.uid ).first
if user
return user
else
registered_user = User.where(:email => access_token.info.email).first
if registered_user
return registered_user
else
user = User.create(name: data["name"],
provider:access_token.provider,
email: data["email"],
uid: access_token.uid ,
password: Devise.friendly_token[0,20],
)
end
end
end
omniauthCallBacksController
class OmniauthCallbacksController < Devise::OmniauthCallbacksController
def google_oauth2
#user = User.find_for_google_oauth2(request.env["omniauth.auth"], current_user)
if #user.persisted?
flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Google"
sign_in_and_redirect #user, :event => :authentication
else
session["devise.google_data"] = request.env["omniauth.auth"]
redirect_to new_user_registration_url
end
end
It looks like the problem is that your find_for_google_oauth2 is creating the user. This means that the else in your google_oauth2 callback isn't getting hit, so it'll never go to your new_user_registration_url. One solution is to separate your find and create steps rather than combining them in find_for_google_oauth2. Then, when the find doesn't find an existing user, you hit your else in your google_oauth2 callback and the omniauth data is put in the session and you get sent to new_user_registration_url. Then once they've entered the extra info and submit the form, you can use that, combined with the omniauth data you saved in the session, to create the user.
Two things about putting the omniauth data in the session:
You probably want to pick what you want to keep from the omniauth hash (especially if you're using CookieStore for the session storage) as it's quite large.
If you're using the CookieStore and Rails < 4 then the omniauth data being stored in the session (i.e. in the cookie on the user's computer) is unencrypted.
I'm trying to add authentications controller for my current devise system, in order to provide multiple logins with facebook and twitter.
To do that, I'm following this tutorial: http://railscasts.com/episodes/236-omniauth-part-2
My problem is, for the person, who hasn't registered yet, and trying to register with twitter.
So I need to create both user and authentication for that.
My code is the following:
user = User.new
token = omni['credentials'].token
token_secret = omni['credentials'].secret
user.provider = omni.provider
user.uid = omni.uid
user.authentications.build(:provider => omni['provider'], :uid => omni['uid'], :token => token, :token_secret => token_secret)
if user.save
flash[:notice] = "Logged in."
sign_in_and_redirect(:user, user)
else
session["devise.user_attributes"] = user.attributes
redirect_to new_user_registration_path
end
So at the end of the registration process, the new user is created. However in the database, I don't see any twitter authentication record with respect to that user.
Is that because of the user.authentications.build ?
That would be great if you can help me.
Thanks.
As a data point: The railscasts you're referring to references Omniauth pre-1.0, which had a slighly different strategy than what that railscsts reference. (Note: I'm using the exact method you're referencing on a live site ). In this case, the build calls "apply_omniauth" -
Make sure you've created (as they reference in the video), a registrations controller which builds the resource. Here is my current working example:
class RegistrationsController < Devise::RegistrationsController
def create
super
session[:omniauth] = nil unless #user.new_record?
end
private
def build_resource(*args)
super
if session[:omniauth]
# apply omniauth calls the user model and applies omniauth session to the info
#user.apply_omniauth(session[:omniauth])
#
#user.valid?
end
end
end
However, you still need to create the authentication record, here is my exact call:
current_user.authentication.create!(:provider => omniauth['provider'], :uid => omniauth['uid'])
Hope it helps.
Yes, it is because of build
User.build # allocates a new record for you
User.create # allocates and then saves a new record for you
So I think you want
user.authentications.create(:provider => omni['provider'],
:uid => omni['uid'],
:token => token,
:token_secret => token_secret)
In addition, you should handle the case where the create does not save (validation problem)
I suppose if you are using Devise+Omniauth , you could take a look at this more recent Railscast. There is a native support of OmniAuth in the new version of Devise gem .
Yes it is because of build, it is use to build a record without saving it in the database (like new).
If in your model you have a User has_many :authentications , you can set the autosave option to true to automatically save the authentications when you are saving the user :
has_many :authentications, autosave: true
I followed the steps that are described in https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview and have a method in user model like this:
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if user = self.find_by_email(data.email)
user
else # Create a user with a stub password.
self.create!(:email => data.email, :password => Devise.friendly_token[0,20])
end
end
I intermittently get errors like
A NoMethodError occurred in omniauth_callbacks#facebook:
undefined method email' for "false":String
app/models/user.rb:138:infind_for_facebook_oauth'
that I haven't been able to reproduce. What is the source of this problem?
I am not sure what causes this either. Here's a work-around that simply creates a new object:
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if data == "false"
self.new
elsif user = self.find_by_email(data.email)
user
else # Create a user with a stub password.
self.create!(:email => data.email, :password => Devise.friendly_token[0,20])
end
end
The controller code shown in the example will then work - it will redirect the user to sign up.
I setup Facebook login with Devise and omniauth with these instructions https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
The Devise wiki gives some instructions for getting facebook info from the hash stored in this variable request.env['omniauth.auth'] See bottom for the hash.
For example, Devise wiki has these two methods for the User.rb model
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if user = User.where(:email => data.email).first
user
else # Create a user with a stub password.
User.create!(:email => data.email, :password => Devise.friendly_token[0,20])
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"]
end
end
end
So, using the hash below, I added the following to those two methods to get the name and image
def self.find_for_facebook_oauth(access_token, signed_in_resource=nil)
data = access_token.extra.raw_info
if user = User.where(:email => data.email).first
user
else # Create a user with a stub password.
User.create!(:email => data.email, :password => Devise.friendly_token[0,20], :name => data.name, :image => access_token.info.image) #I added access_token.info.image based on first answer
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"]
user.name = data["name"]
user.image = access_token.info.image #i changed this based on first answer below
end
end
end
Then in my view, I added the following to show the user name and image
<p>Name:<%= user.name %></p>
<p>Image: <%= image_tag user.image %>
However, only the name is showing. No image.
In my database, I have a name and an image column. The name from Facebook is being stored, but the image column says 'nil'
Any ideas how I can get the image to work?
Hash stored in request.env['omniauth.auth'] https://github.com/mkdynamic/omniauth-facebook/blob/master/lib/omniauth/strategies/facebook.rb#L31-47
info do
prune!({
'nickname' => raw_info['username'],
'email' => raw_info['email'],
'name' => raw_info['name'],
'first_name' => raw_info['first_name'],
'last_name' => raw_info['last_name'],
'image' => "#{options[:secure_image_url] ? 'https' : 'http'}://graph.facebook.com/#{uid}/picture?type=square",
'description' => raw_info['bio'],
'urls' => {
'Facebook' => raw_info['link'],
'Website' => raw_info['website']
},
'location' => (raw_info['location'] || {})['name'],
'verified' => raw_info['verified']
})
end
The image can be found at env["omniauth.auth"]["info"]["image"]. So in your case, access_token.info.image.
If you want to take a good look at the hash of nested hashes returned and see for yourself where everything is, put this as the first line of your callback controller:
render :text => "<pre>" + env["omniauth.auth"].to_yaml and return
EDIT: Ok, so here's what you need to do:
def self.find_for_facebook_oauth(omniauth)
if user = User.find_by_email(omniauth.info.email)
if omniauth.info.image.present?
user.update_attribute(:image, omniauth.info.image)
end
user
else # Create a user with a stub password.
User.create!(:email => omniauth.info.email,
:name => omniauth.info.name,
:image => omniauth.info.image,
:password => Devise.friendly_token[0,20])
end
end
As for the other method, if I'm not mistaken, it should look like this:
def self.new_with_session(params, session)
super.tap do |user|
if omniauth = session["devise.facebook_data"]
user.email = omniauth.info.email
user.name = omniauth.info.name
user.image = omniauth.info.image
end
end
end
But when is this method used? It's used by Devise when something goes wrong when creating your user. Imagine that the authentication provider doesn't give you an email (Twitter, for example, does this), what can you do? Well, you can redirect the user to your sign up page where he can complete the signup process. But if you redirect the user, you lose the data received by the oauth. The solution is to put this data into the session.
So in your controller, you should have something like:
if user.save
sign_in_and_redirect user, :event => :authentication
else
session["devise.facebook_data"] = env["omniauth.auth"]
redirect_to new_user_registration_url
end
Another problem, however, is that most of the times the data returned by the authentication provider is too big to fit in the session, so we have to pick exactly what we want to put in the session. Since you are only getting a name and an image, you can trim the extra info like so:
session["devise.facebook_data"] = env["omniauth.auth"].except('extra')
I'm trying to build Facebook OAuth into my existing Authlogic login system. I have the OAuth part complete, and stored the facebook access_token. The problem I'm facing is to actually log the user in (create a session) without the user typing in their password.
#facebook's OAuth callback
def callback
access_token = client.web_server.get_access_token(params[:code], :redirect_uri => redirect_uri)
fb_user = JSON.parse(access_token.get('/me'))
#user = User.find_by_facebook_id(fb_user["id"]) || User.find_by_email(fb_user["email"]) || User.new
#user.update_attributes({
:facebook_id => fb_user["id"],
:first_name => fb_user["first_name"],
:last_name => fb_user["last_name"],
:gender => fb_user["gender"],
:email => fb_user["email"],
:timezone => fb_user["timezone"],
:locale => fb_user["locale"],
:facebook_url => fb_user["link"],
:facebook_access_token => access_token.token
}) #unless #user.updated_at < 2.days.ago
# TODO: set current_user
# Maybe something like this?
# #user_session = UserSession.new({
# :remember_me => true,
# :password =>"[FILTERED]",
# :email => email
# }).save
flash[:success] = "Welcome, #{#user.name}"
redirect_to :root
end
Nevermind I figured it out. It was in the README the whole time.
UserSession.new(#user, true) //true = persistent session
