Rails Devise Omniauth new_user_registration_url

Question

ich hatte vor einigen monaten devise gem und omniauth-facebook in meine app implementiert und alles wurde wie gewohnt bearbeitet, bis jetzt habe ich meinen fb user aus db gelöscht. Jetzt versuche ich mich erneut als nicht existierender Benutzer anzumelden und werde die ganze Zeit an das Devise-Anmeldeformular weitergeleitet.

So kann ich mich nicht anmelden/registrieren meine FB-Benutzer in meine App.

Was kann diese Art von Problem verursachen?

routes.rb

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

omniouth_callback_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 
    def facebook 
    # You need to implement the method below in your model (e.g. app/models/user.rb) 
    @user = User.from_omniauth(request.env["omniauth.auth"]) 

    if @user.persisted? 
     sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated 
     set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format? 
    else 
     session["devise.facebook_data"] = request.env["omniauth.auth"] 
     redirect_to new_user_registration_url 
    end 
    end 

    def failure 
    redirect_to root_path 
    end 
end 

user.rb Modell

class User < ApplicationRecord 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable, :omniauthable, :omniauth_providers => [:facebook] 

    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 


    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 
    end 
    end

Answer 1

Ich fand den Grund in user.rb-Modell Ich hatte eine Assoziation gehört_to: somemodel und dass ich dort zum Testen einiger Modellrelationen gesetzt wurde.

Also diese Zeile kommentieren Ich bin von Facebook eingeloggt!
