无法获取 current_user 设备和 oAuth facebook

Question

我仅使用 Omniauth 从 Facebook 登录用户

** Users::OmniauthCallbackController**

class Users::OmniauthCallbacksController <

设计::OmniauthCallbacksController

def facebook
  @user = User.from_omniauth(request.env["omniauth.auth"])

  if @user.persisted?
    sign_in_and_redirect @user, :event => :authentication
    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 games_path
end

结束

但是当我尝试将 current_user 发送到另一个控制器时，它总是 returns nil。

我读到设计有一个内置函数 current_user 但它似乎不能正常工作（每次都返回 nil）所以我实现了另一种方法。

current_user帮手

before_action :define_current_user
def current_user
  User.find_by id: session["current_user_id"]
end
helper_method :current_user

我怎样才能让它发挥作用？

User.rb

 class User < ApplicationRecord

 belongs_to :team

 # Include default devise modules. Others available are:
 # :confirmable, :lockable, :timeoutable and :omniauthable
 devise :database_authenticatable,  :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

 #Saving new user to the database 
 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
       user.image = auth.info.avatar
       user.save!
    end     
 end
end

Answer 1

不要忘记向需要的控制器添加 before_action :authenticate_user! 回调。在这种情况下，您将能够从 Devise

获得默认值 current_user
