我一直在尝试使用Mongodb与CodeIgniter 4，但面临的问题。
puppyModel.php -中文版

<?php

namespace App\Models;
use CodeIgniter\Model;
use App\Libraries\Mongo;

class puppyModel{
    /**
     * @var Mongo
     */
    protected $m;

    /**
     *
     */
    public function __construct()
    {
        $this->m = new Mongo();
    }

    public function getList(string $collection, array $where = [], array $options = [], array $select = [])
    {
        return $this->m->options($options)->select($select)->where($where)->find($collection)->toArray();
    }
}

?>

Home.php（控制器）-

<?php

namespace App\Controllers;
use CodeIgniter\Controller;
use app\Models\puppyModel;

class Home extends BaseController{
    public function index(){
        $puppyModel = new puppyModel();
        $data1 = $puppyModel->getList();
        print_r($data1);
    }
}

我收到这个错误-

CRITICAL - 2022-02-02 23:58:05 --> Class "app\Models\puppyModel" not found

我使用此存储库作为参考-https://github.com/bertugfahriozer/ci4mongodblibrary我已经将配置和库文件放置在存储库中并更改了名称空间。
