Devise + Omniauth + Facebook

Question

我對RoR很陌生，對我很裸露。我已按照railscasts視頻＃235和＃236設置OmniAuth w/Devise。我可以讓一切正常工作，當我在驗證控制器中添加條件語句時，我的問題就出現了。我收到以下錯誤：

NoMethodError在AuthenticationsController＃Facebook的 未定義的方法`TO_KEY」爲：用戶：符號 這似乎在被crapping出來：

sign_in_and_redirect(:user, authentication.user)

我在這裏檢查其他的答案，似乎沒有有一個解決方案。我發現一個與Heroku有關，但我正在開發這個消息。任何幫助將不勝感激。

authentications_controller.rb

 
def facebook 
    omniauth = request.env["omniauth.auth"] 
    authentication = Authentication.find_by_provider_and_uid(omniauth.provider, omniauth.uid) 
    if authentication 
     flash[:notice] = "Signed in successfully." 
     sign_in_and_redirect(:user, authentication.user) 
    elsif current_user 
     current_user.authentications.create!(:provider => omniauth['provider'], :uid => omniauth['uid']) 
     flash[:notice] = "Authentication successful." 
     redirect_to authentications_url 
    else 
     @user = User.new 
     @user.apply_omniauth(omniauth) 
     if @user.save 
     flash[:notice] = "Signed in successfully." 
     sign_in_and_redirect(:user, @user) 
     else 
     session[:omniauth] = omniauth.except('extra') 
     redirect_to new_user_registration_url 
     end 
    end 
    end

registrations_controller.rb

 

    class RegistrationsController Devise::RegistrationsController 
     def create 
     super 
     session[:omniauth] = nil unless @user.new_record? 
     end 

     private 

     def build_resource(*args) 
     super 
     if session[:omniauth] 
      @user.apply_omniauth(session[:omniauth]) 
      @user.valid? 
     end 
     end 
    end 

的routes.rb

 

    resources :authentications 
     get '/auth/:provider/callback' => 'authentications#facebook' 
     devise_for :users, :controllers => {:registrations => 'registrations', :omniauth_callbacks => 'authentications'} 

user.rb

 

    class User ActiveRecord::Base 
     has_many :authentications 

     # Include default devise modules. Others available are: 
     # :confirmable, :lockable, :timeoutable and :omniauthable 
     devise :database_authenticatable, :registerable, 
      :recoverable, :rememberable, :trackable, :validatable, :omniauthable 

     def apply_omniauth(omniauth) 
     self.email = omniauth.info.email if email.blank? 
     authentications.build(:provider => omniauth['provider'], :uid => omniauth['uid']) 
     end 

     def password_required? 
     (authentications.empty? || !password.blank?) && super 
     end 
    end

Answer 1

變化

sign_in_and_redirect(:user, authentication.user) 

要

sign_in_and_redirect(authentication.user) 

Answer 2

的問題是與哈希格式。我改變了它：

sign_in_and_redirect(:user, authentication.user.user_id)

並解決了它。
