class Account extends CI_Controller {

    public function _construct() {
        parent::__construct();
        $this->load->model('Account_model');
    }


    public function index() {

        $mdat=[
            'active_controller' => 'master',
            'active_function' => 'account/account_view',
        ];

        $this->load->view('admin/global/menu', $mdat);

        $data['books']=$this->Account_model->get_all_acc();
        $this->load->view('account_view',$data);

this is my model :
class Account_model extends CI_Model
{
    var $table = 'books';

    public function acc_add($data) {

        $this->db->insert($this->table,$data);
        return $this->db->insert_id();
    }

    public function get_all_acc() {
        $this->db->from('books');
        $query = $this->db->get();
        return $query->result();
    }

尝试将您的函数结构更改为以下结构：

public function __construct() {
    parent::__construct();
    $this->load->model('Account_model');
}

因为构造函数需要双下划线，而您只需键入一个下划线
