Magento — Как получить данные из пользовательской таблицы MySQL в таблице сетки Adminhtml

Я использую Magento 1.9.0.1!

Прямо сейчас я работаю над пользовательским расширением magento.
Я хочу отобразить данные из пользовательской таблицы MySQL на свою пользовательскую страницу в таблице сетки HTML.

Вот все файлы, которые я создал, чтобы достичь этого.

В моем /app/code/community/VivasIndustries/SmsNotification/etc/config.xml:

это Grid.php Файл взят из руководства отсюда: http://inchoo.net/magento/how-to-create-a-custom-grid-from-scratch/ и некоторые правки из этого ответа: https://magento.stackexchange.com/questions/54897/how-to-get-data-from-custom-mysql-table-into-your-adminhtml-grid-table/54898#54898

Позвольте мне показать вам структуру и данные, которые я хочу показать в таблице сетки:

Следующие 3 файла созданы, потому что мне так сказали в этом ответе: https://magento.stackexchange.com/questions/54897/how-to-get-data-from-custom-mysql-table-into-your-adminhtml-grid-table/54898#54898

Вот что у меня есть в: /app/code/community/VivasIndustries/SmsNotification/Model/SmsNotification.php:

<?php
class VivasIndustries_SmsNotification_Model_Smsnotification extends extends Mage_Core_Model_Abstract
{
public function _construct()
{
$this->_init('smsnotification/smsnotification');
}

}

В моем /app/code/community/VivasIndustries/SmsNotification/Model/Resource/Smsnotification.php:

<?php
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification extends Mage_Core_Model_Resource_Db_Abstract
{
/**
* Initialize resource model
*
* @return void
*/
public function _construct()
{
$this->_init('smsnotification/smsnotification','id');
}
}

В моем /app/code/community/VivasIndustries/SmsNotification/Model/Resource/Smsnotification/Collection.php:

<?php
class VivasIndustries_SmsNotification_Model_Resource_Smsnotification_Collection extends Mage_Core_Model_Resource_Db_Collection_Abstract{
protected function _constuct(){
$this->_init('smsnotification/smsnotification');
}
}

Мой вопрос в том, что я должен изменить в своем Grid.php файл, так что эта таблица покажет данные из таблицы VivasIndustries_SmsNotification только ?

Заранее спасибо!
