Rails Devise Omniauth new_user_registration_url

Question

私は数ヶ月前に私のアプリにdevise gemとomniauth-facebookを実装していました。 今、私は存在しないユーザーとして再度サインインしようとしており、Devise Sign Upフォームにリダイレクトされています。

FBのユーザーを自分のアプリにログイン/登録できません。

このような問題の原因は何ですか？

routes.rbを

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モデル

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

私はuser.rbモデルの理由を見つけました。belongs_to：somemodelという関連があり、モデル関係をテストするためにそこに配置されました。
