代码点火器负载模型错误

hi我是codeigniter的新手我试图在控制器中加载一个模型未找到Fatal error: Class 'application'models'CI_Model'。在加载模型之前，我需要设置一些东西吗

我的控制器：

class VerifyLogin extends CI_Controller{
        function __construct(){
            parent::__construct();
            $this->load->model('user','',TRUE);
        }
        function index(){
            $this->load->library('form_validation');
            $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|min_length[6]');
            $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|is_unique[users.email]');
            if ($this->form_validation->run()==false)
            {
                $this->load->view('header');
                $this->load->view('marketing/marketing_custom_header');
                $this->load->view('menu_2');
                $this->load->view('marketing/marketing');
                $this->load->view('footer');
            }else{
                redirect('home', 'refresh');
            }
        }
    } 

我的型号：

    class User extends CI_Model {
        function __construct(){
            parent::__construct();
        }

         function  login($email,$password ){
             $this->db ->select('id, email, password');
             $this->db -> from('users');
             $this->db -> where('email',$email);
             $this->db -> where('password',$password);
             $this->db -> limit(1);
             $query ="";
             $query ->$this ->db ->get();
             if($query ->num_rows()==1){
                 return $query->resilt();
             }else{
                 return false;
             }
         }

    }
