整合Wicked，Devise和Omniauth-Facebook

Question

I am developing an application using these three gem I wrote in the title of this post. I set up devise with the confirmable module(?), so when a user creates an account with its email/password, it receives a confirmation email. If the user sign up with facebook (using omniauth-facebook gem) devise skips the confirmation step.

In user.rb

    "Of course the :confirmable is active in the model"
    ...

    # Omniauth-facebook
    def self.find_for_facebook_oauth(auth)
      where(auth.slice(:provider, :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]
        user.first_name = auth.info.first_name
        user.last_name = auth.info.last_name
        user.skip_confirmation!
        # user.image = auth.info.image # assuming the user model has an image
      end
    end

    ...

The thing comes when I added the wicked gem for the wizard. I configured the routes file

in routes.rb

MyApp::Application.routes.draw do

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

  root 'home#index'

  # Registration wizard routes
  resources :after_register
end

The I created a registration_controller to override the devise registration methods

    class RegistrationsController < Devise::RegistrationsController

      def create
        super
      end

    protected

     def after_sign_in_path_for(resource)
       puts "<<<<<<<<<<<<<<<< SIGN IN"
       after_register_path(:import_contacts)
     end

     def after_sign_up_path_for(resource)
       puts "<<<<<<<<<<<<<<<< SIGN UP ACTIVE"
     after_register_path(:import_contacts)
   end

   def after_inactive_sign_up_path_for(resource)
    puts "<<<<<<<<<<<<<<<< SIGN IN INACTIVE"
    after_register_path(:import_contacts)
   end
 end

And then, I created a new controller to handle the steps of the wizard with wicked.

   class AfterRegisterController < ApplicationController
     include Wicked::Wizard
     before_filter :authenticate_user!

     steps :import_contacts, :select_agents, :wish_form

     def show
       @user = current_user
       render_wizard
     end

     def update
       @user = current_user
       @user.attributes = params[:user]
       render_wizard @user
     end

   end

When I create a user rith email/password, the wizard comes and everything works fine, but when I try to sign up with facebook, the wizars never comes.

Any hint???

Thank you!!

Answer 1

If everything is configured in the usual way (and what I can see looks pretty standard), then signing in using Facebook won't go via the RegistrationsController at all. It will go via the OmniauthCallbacks controller which you haven't posted the code for. It depends what you do in there when they log in via Facebook. I assume that you have a facebook() method which calls User.find_for_facebook_oauth(auth) . Are you then just signing them in rather than going to the RegistrationsController ? If so, then the RegistrationsController won't be touched, so its overridden after_sign_in_path_for won't have any effect.

If you want to have your overridden after_sign_in_path_for take effect throughout your app, you can define it in your ApplicationController . If you only want it to take effect in your OmniauthCallbacksController , you could define it there. In either case, they'll be hitting it every time they log in using Facebook (and if you put it in the ApplicationController , every time anyone logs in using any method), so you'd need to keep track of the fact that they have already been through the wizard, assuming you want to make sure that it only happens the first time they sign in. If you're using the devise :trackable module, perhaps checking the user.sign_in_count would be appropriate, or perhaps you have some other way to easily check if they have been through the wizard already.

UPDATE FOR COMMENT QUESTIONS:

Your first question: "Assuming I put the after_sign_in_path_fot in ApplicationController, I should remove the after_inactive_sign_up_path_for method in RegistrationsController, right?" It depends on what behaviour you want. With the RegistrationsController as in your question it will go to the wizard after they've signed up and before they've confirmed their email (because of after_inactive_sign_up_path_for which will be called in this case). When they confirm and sign in, the after_sign_in_path_for in ApplicationController will send them to the wizard again. So yes, remove inactive from RegistrationsController if you just want wizard after sign in. Then probably after_sign_up_path_for(resource) in RegistrationsController is unnecessary because the default implementation in devise just calls after_sign_in_path_for(resource) which you will have in your ApplicationController . Anyway, after_sign_up_path_for() won't be called if you always require confirmation because of the logic in the default implementation of RegistrationsController.create() - requiring confirmation will result in resource.active_for_authentication? returning false which causes after_inactive_sign_up_path_for(resource) to be called.

For the question in your second comment, you said "If I remove the after_sign_in_path_for in ApplicationController" - I assume you meant RegistrationsController ? If that's right, then yes, there would be no methods needed in your overridden version of RegistrationsController (if that's the whole controller you pasted in your question) because your create() just calls super , the after_sign_in_path_for would be in ApplicationController and you probably don't want either of the after_(inactive)_sign_up_path_for methods as discussed above. So yes, there would be no need for your RegistrationsController . You could remove it completely and remove the :registrations => "registrations" in routes.rb - the devise implementation of RegistrationsController will then be used again.

Then you say "just override the methods of RegistrationsController in ApplicationController?". The only method you will have left from your RegistrationsController is the after_sign_in_path_for(resource) in ApplicationController , so I don't think there will be any other methods from your RegistrationsController that you need in ApplicationController . Let me know if I've missed one of your requirements or made an incorrect assumption.
