. @user не сохраняется, перенаправляется на страницу регистрации

Question

Я выполнил все инструкции в прохождении Omniauth.

Обратите внимание, что моя модель пользователя не имеет имени или свойств изображения.

Я выполнил инструкции в учебнике Rails. Тем не менее, я должен изменить это:

class User < ActiveRecord::Base 
    # 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.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 

    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 
end 

к этому:

class User < ActiveRecord::Base 
    # 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.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 

    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 
end 

• ошибка была быть брошенным, потому что пользователь не имеет name или image свойств. Это привело к новой ошибке: @user, созданный в Omniauth_callbacks_controller, не сохраняется, поэтому вместо входа в систему я просто перенаправляюсь обратно на страницу регистрации пользователя.

omniauth_callbacks_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"]) 
    puts "BEFORE IF STATEMENT" 
    puts @user.inspect 
    if @user.persisted? 
     puts "INSIDE IF STATEMENT" 
     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 
     puts "AFTER ELSE STATEMENT" 
     session["devise.facebook_data"] = request.env["omniauth.auth"] 
     redirect_to new_user_registration_url 
    end 
    end 
end 

сервера считана, который включает в себя puts заявление и объект @user. Вы увидите, что большинство ее полей равны нулю:

Обратите внимание на puts внутри «если» заявление никогда не было напечатано.

routes.rb:

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

    resources :restaurants do 
    resources :reviews 
    end 

    root to: "restaurants#index" 

Я в тупик.

Answer 1

Если вы удалите опцию :validatable, тогда она будет работать.
