How to solve "Class ... not found" error in Yii2?

Question

Yii

Hello. I have the following problem.
When accessing the controller action, the error "Class 'app\models\customer\CustomerRecord' not found" is thrown.
The contents of the index.php file

<?php
ini_set('display_errors', true);
define('YII_DEBUG', true);
require(__DIR__ . '/../vendor/autoload.php');
require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');
$config = require(__DIR__ . '/../config/web.php');
(new yii\web\Application($config))->run();

Contents of the CustomerRecord.php file

<?php
namespace app\models\customer;

use yii\db\ActiveRecord;

class CustomerRecord extends ActiveRecord
{
  public static function tableName()
  {
    return 'customer';
  }

  public function rules()
  {
    return [
      ['id', 'number'],
      ['name', 'string', 'max' => '256'],
      ['birth_date', 'date', 'format' => 'Y-m-d'],
      ['notes', 'safe']
    ];
  }
}

Well, the contents of the file CustomerController.php

<?php
namespace app\controllers;

use app\models\customer\Customer;
use app\models\customer\CustomerRecord;
use app\models\customer\Phone;
use app\models\customer\PhoneRecord;
use yii\web\Controller;

class CustomerController extends Controller
{
  public function actionIndex()
  {
    $record = $this->findRecordsByQuery();
    return $this->render('index', compact('record'));
  }

  public function actionAdd()
  {
    $customer = new CustomerRecord;
    $phone = new PhoneRecord;
    return $this->render('add', compact('customer', 'phone'));
  }
}

I study according to the book by M. Safronov. - Development of web applications in Yii2.
It seems that he did everything according to the book, but apparently he missed something somewhere.
I can assume that the autoloader does not work, but where to fix it. In general, it will help to understand.
Thanks in advance to all who respond.

Answer 1

Your model namespace is app\models\customer, and the file, as you say, is in app\models. Fix it.
