How to correctly connect your class through the use construct?

Question

1C-Bitrix

Created two classes in /local/php_interface/lib/
directory DayorderTable - ORM table wrapper DayorderHelper - ORM
helper class

included classes in init.php

Bitrix\Main\Loader::registerAutoLoadClasses(null, [
'DayorderTable' => '/local /php_interface/lib/DayorderTable.php',
'DayorderHelper' => '/local/php_interface/lib/DayorderHelper.php',
]);
Now both classes are visible from anywhere in the project, I can simply access the DayorderTable ORM class on the site page and call the getList method, everything works as it should.

But there is a problem, when in the DayorderHelper.php file I want to make the DayorderTable class visible so that I can access the ORM inside the helper methods, then Bitrix swears, writesClass 'DayordersTable' not

found

use Bitrix\Main;
use Bitrix\Main\Entity;
use Bitrix\Main\Type;
use DayordersTable; // здесь я думаю не правильно указано имя класса ORM с которым работает DayorderHelper в методе GetElement

// Содержит вспомогательные методы для работы с HlbookTable
class DayorderHelper {

    // получаем запись из ORM
    public static function GetElement($deliveryAddress) {
        return $element  = DayordersTable::getList(array(
            'select'  => array('*'), // имена полей, которые необходимо получить в результате
            'filter'  => array('DELIVERY_ADDRESS' => $deliveryAddress), // описание фильтра для WHERE и HAVING
            'limit'   => 1, // количество записей
        ))->fetch();
    }
}

How to correctly connect your class through the use construct so that it becomes visible in the code of another custom class?

Answer 1

// here I think the name of the ORM class with which DayorderHelper works in the GetElement method is not correctly indicated

You think right))

So-so decision to place classes in php_interface. Create a separate module, include it in init.php (if you always need a module) and that's it. All classes will be loaded automatically according to the class name.
Well, about the wrong name, they already wrote to you in the comments.
