php - 找不到型号

Question

无法找到您指定的模型：Empresa_model

文件名：/opt/lampp/htdocs/actzap_CI/system/core/Loader.php

我已经多次编写此代码，但问题仍然存在，有人可以帮忙吗？对不起，我的英语不好

模型：

    class Empresa_model extends CI_Model {
        //...
        function __construct(){
              parent::__construct();
        }

        public function listaEmpresas(){

            return $this->db->get("empresa")->result_array();
        }
        //...
    }

控制器：

class Empresa_controller extends CI_Controller

    public function index()
    {
        $this->load->model('empresa_model');

        $lista = $this->empresa_model->listaEmpresas();

        $dados = array("empresa" => $lista);

        $this->template->show('empresa', $dados);
    }
    //...
}

完全错误：
