NoMethodError（未定義方法`persisted？'為true：TrueClass）

Question

我正在實現Rails Web應用程序，在此應用程序中，我使用Devise + Omniauth進行身份驗證。 在我的Devise模型中，我還使用了確認塊。

現在，當我嘗試通過omniauth為facebook或google實現社交登錄時，出現以下錯誤

  NoMethodError at /customer/auth/google_oauth2/callback
  undefined method `persisted?' for true:TrueClass

這是我的omniauth_callbacks控制器的代碼

    class OmniauthCallbacksController < Devise::OmniauthCallbacksController

    skip_before_filter :authenticate_user!
    def all
        p env["omniauth.auth"]
        user = User.from_omniauth(env["omniauth.auth"], current_user)
        if user.persisted?
            flash[:notice] = "You are in..!!! Go to edit profile to see the status for the accounts"
            sign_in_and_redirect(user)
        else
            session["devise.user_attributes"] = user.attributes
            redirect_to new_user_registration_url
        end
    end

      def failure      
        super
      end


    alias_method :facebook, :all
    alias_method :google_oauth2, :all
end

這是我的用戶模型中的代碼片段

類User <ActiveRecord :: Base

devise :database_authenticatable, :registerable,
       :recoverable, :rememberable, :trackable, :validatable,:confirmable,:token_authenticatable

def self.from_omniauth(auth, current_user)    
    authorization = Authorization.where(:provider => auth.provider, 
                    :uid => auth.uid.to_s, 
                    :token => auth.credentials.token, 
                    :secret => auth.credentials.secret).first_or_initialize

    if authorization.user.blank?
        user = current_user || User.where('email = ?', auth["info"]["email"]).first        
        if user.blank?       
          user = User.new
          user.name = auth.info.name
          user.email= auth.info.email
          if auth.provider == "twitter" 
            user.save(:validate => false) 
          else
            user.skip_confirmation!
            user.save(:validate => false)
          end
        end
        authorization.username = auth.info.nickname
        authorization.user_id = user.id
        authorization.save
    end
    authorization.user
end

結束

我的用戶模型有很多授權模型（創建來處理來自多個提供商的帳戶）

class Authorization < ActiveRecord::Base
    belongs_to :user

    after_create :fetch_details



    def fetch_details
        self.send("fetch_details_from_#{self.provider.downcase}")
    end


    def fetch_details_from_facebook
        graph = Koala::Facebook::API.new(self.token)
        facebook_data = graph.get_object("me")
        self.username = facebook_data['username']
        self.save
    end
 end

誰能幫助我找到為什么我會得到這個“持久化”的未定義方法？ 對於true：TrueClass

錯誤？

Answer 1

current_user幫助程序在omniauth行中扮演什么角色？ 我假設它正在與omniauth環境變量產生某種沖突。

嘗試更改：

user = User.from_omniauth(env["omniauth.auth"], current_user)

至：

user = User.from_omniauth(env["omniauth.auth"])
