В Yii2 я пытался создать динамическую c форму, используя приведенные ниже учебники.
Yii2-dynamicForm - GitHub и Youtube Tutorial .
Я выполнил тот же шаг, что и в учебниках, к сожалению, у меня возникает ошибка (скриншот прилагается) 
И я не могу решить эта ошибка, может ли кто-нибудь помочь мне найти то, что мне не хватает.
Для справки я прилагаю свои модели здесь, остальные контроллеры и представления такие же, как учебники.
Модель запроса
<?php
namespace app\models;
use Yii;
class Request extends \yii\db\ActiveRecord
{
public static function tableName()
{
return 'request';
}
public function rules()
{
return [
[['req_date', 'req_on', 'req_updated_on'], 'safe'],
[['req_job', 'req_type', 'material_type', 'req_status'], 'required'],
[['req_by'], 'integer'],
[['req_status'], 'string'],
[['req_job', 'req_type'], 'string', 'max' => 100],
[['material_type'], 'string', 'max' => 150],
];
}
public function attributeLabels()
{
return [
'req_id' => 'Req ID',
'req_date' => 'Req Date',
'req_job' => 'Job No',
'req_type' => 'Type of Request',
'req_on' => 'Required On',
'material_type' => 'Material Type',
'req_by' => 'Req By',
'req_updated_on' => 'Req Updated On',
'req_status' => 'Request Status',
];
}
}
Модель RequestItems
<?php
namespace app\models;
use Yii;
use yii\base\Model;
/**
* This is the model class for table "request_items".
*
* @property int $req_item_id
* @property int $req_id

*/
class RequestItems extends \yii\db\ActiveRecord
{
/**
* {@inheritdoc}
*/
public static function tableName()
{
return 'request_items';
}
/**
* {@inheritdoc}
*/
public function rules()
{
return [
[['req_id', 'item_name', 'item_qty', 'item_unit'], 'required'],
[['req_id'], 'integer'],
[['item_name'], 'string', 'max' => 100],
[['item_qty', 'item_unit'], 'string', 'max' => 25],
];
}
/**

public function attributeLabels()
{
return [
'req_item_id' => 'Req Item ID',
'req_id' => 'Req ID',
'item_name' => 'Item Name',
