Login / Register to Refinery with Omniauth (facebook, twitter, openid, etc)

refinery_omniauth.rb

# Create a role user (no perms). Fire up the console rails c
$> Role.create(:title=>'User')

# In your Gemfile add
gem 'oa-oauth', :require => 'omniauth/oauth'

# At the beginning of devise.rb. You can also create a yaml file and instantiate when Rails begin
# For shake of simplicity I added the credentials at devise.rb
Facebook = Rails.env.development? ? {:app_id => 2621xxx, :secret => 'e81f33d042xxxxx'} : 
                                    {:app_id => 1749xxx9, :secret => '13c11be6628dc1xxxx'}

# In devise.rb inside the config block
config.omniauth :facebook,  Facebook[:app_id], Facebook[:secret] , {
    :scope => "email,offline_access,share_item, status_update, user_birthday"}

# rake refinery:override controller=registrations
# 1. We need to create a username so that we comply with the validation
# After line 15 we may add the following, if we have an email
@user.username = @user.email.split('@')[0]

# By default refinery adds the refinery role when somebody registers.
# We keep this behaviour only for the first user. At line 20 we add:

if !refinery_users_exist?
   @user.add_role(:refinery)
   @user.plugins = @selected_plugin_titles
else
   @user.add_role(:user)
end

# Then at line 55 we modify the redirect? method
# We remove the condition refinery_users_exist?
def redirect?
  if refinery_user?
    redirect_to admin_users_url
  end
end

# We edit routes.rb as following
 devise_for :users, :controllers => {
   :registrations => "users",
   :sessions=>"sessions",
   :omniauth_callbacks => "users/omniauth_callbacks"
 }, :stateless_token => false
  
match "/registrations/auth/facebook" => redirect("/users/auth/facebook")

# We add somewhere in our views the Login with Facebook button
<%= url_for users_auth_facebook_path(:facebook) %>

# We then create the controller users/omniauth_callbacks_controller.rb
class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController
  def facebook
    # You need to implement the method below in your model
    @user = User.find_for_facebook_oauth(env["omniauth.auth"], current_user)

    if @user.persisted?
      flash[:notice] = I18n.t "devise.omniauth_callbacks.success", :kind => "Facebook"
      sign_in_and_redirect @user, :event => :authentication
    else
      session["devise.facebook_data"] = env["omniauth.auth"]
      redirect_to new_user_registration_url
    end
  end
end

# And finally we add the following method to user.rb
# Of course the Facebookdata contains different data according to the permissions 
#   we set at devise.rb (omniauth config).
# Do not forget we need a password for devise (so we create a random one) and a
#   a password. We also need to store the Facebook token if we need offline access
# If you ask for more user data then you should modify your user table accordingly

  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 an user with a stub password.
      user = User.new(:email => data["email"], :password => Devise.friendly_token[0,20], 
                  :username => data['name'], :first_name=>data['first_name'],
                  :last_name=>data['last_name'],:birthday => data['birthday'], 
                  :gender => data['gender'], :uid => data['id'],
                  :token => access_token['credentials']['token'])
      user.add_role(:user)
      user.save! 
    end
  end

# For this example we create the following migration
class AddFieldsToUser < ActiveRecord::Migration
  def self.up
    add_column :users, :uid, :bigint, :limit => 30
    add_column :users, :token, :text
    add_column :users, :first_name, :string
    add_column :users, :last_name, :string
    add_column :users, :birthday, :date
    add_column :users, :gender, :string, :limit => 15
    remove_column :users, :password_salt
  end

  def self.down
    remove_column :users, :uid
    remove_column :users, :token
    remove_column :users, :first_name
    remove_column :users, :last_name
    remove_column :users, :birthday

end

Did you create the users/ominiauth_...callbacks ? I think you also have to set it properly at devise.rb

For some reason there is no route matching "/users/auth/facebook". That falls through to refinery's default pages route. Don't know if that is something you ran across when you were first implementing or not? Any insight there? I'll keep plugging at it and let you know what I find.

I did create the users/ominiauth_...callbacks and setup devise.rb

config.omniauth :facebook, Facebook[:app_id], Facebook[:secret]

wasn't worried about scope for my case. The callback route is recognized. It's the initial login /users/auth/facebook is what isn't picked up for some reason.

@freemarmoset -- maybe this link helps? https://github.com/plataformatec/devise/issues/closed#issue/916

registrations changed users so you must run this command
rake refinery:override controller=users

Also you must change following items
for user login
<%= url_for users_auth_facebook_path(:facebook) %>

on routes.rb

devise_for :users, :controllers => {
:registrations => "users",
:sessions=>"sessions",
:omniauth_callbacks => "users/omniauth_callbacks"
}, :stateless_token => false

match "/users/auth/facebook" => redirect("/users/auth/facebook")

Thanks for your effort.

Thanx man. I guess it should be a bit outdated by now though

After adding in @omeryavuz latest code I am getting nasty redirect loop issues... anyway of fixing this?

Link:

<%= link_to "Sign in with Olympus", users_auth_olympus_path %>

Routes.rb:
devise_for :users, :controllers => {
:registrations => "users",
:sessions=>"sessions",
:omniauth_callbacks => "users/omniauth_callbacks"
}, :stateless_token => false

devise_scope :users do
match "/users/auth/olympus" => redirect("/users/auth/olympus")
end

Olympus is the name of a 3rd party oauth system I have built
