如何在codeigniter控制器中使用模型？

Question

我对 codeigniter-3 框架非常陌生，我在像这样的控制器中使用模型 $this->load->model('model_name') 它工作正常，我正在尝试使用以下方式，但它抛出了一个错误，你能帮我解决这个问题

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

你可以尝试一下

<?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;
    }
}
