如何在codeigniter控制器中使用模型？

Question

我對codeigniter-3 框架非常陌生，我在像這樣的控制器中使用模型$this->load->model('model_name') 它工作正常，我正在嘗試使用以下方式，但它拋出了一個錯誤，你能幫我解決這個問題

An uncaught Exception was encountered

Type: Error

Message: Class 'models\TestModel' not found

TestController.php

#

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
use \models\TestModel;

class TestController extends CI_Controller {

    public function student(){
        $obj = new TestModel();
        $value = $obj->student_college();
        echo $value;
    }
}

Answer 1

你可以嘗試一下

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class TestController extends CI_Controller {
    public function __construct() {
        parent::__construct();
        // Load model
        $this->load->model('TestModel');
    }
    public function student(){
        $obj = new TestModel();
        $value = $obj->student_college();
        echo $value;
    }
}
