我的首頁控制器

Homescontroller.rb

class HomeController < ApplicationController 
    before_filter :authenticate_user! 

    def index 

    end 
end 

我的用戶模型

User.rb

class User < ActiveRecord::Base 

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

# Setup accessible (or protected) attributes for your model 
    attr_accessible :email, :password, :password_confirmation, :remember_me, :sign_in_count 

end 

Rotes.rb

Myapp::Application.routes.draw do 

    devise_for :users 

    root to: "home#index" 

end

嘗試刪除ApplicationController中的'clear_helpers'方法,因爲它有時會阻塞設計加載他的助手。
