Magento 2 Class in Module

Hello

 

Good morning i'm here for help again ( I almost finish promise ), I'm trying to adapt a Prestashop module for Magento 2 but i'm missing some explanation for the class. The module himself have some class to use for example :

 

class myclass extends ObjectModel
{

    public $toreplace;
    public $replaceby;

    public static $definition = array(
        'table' => 'mytable',
        'primary' => 'id',
        'multilang' => false,
        'fields' => array(
            'toreplace' => array('type' => self::TYPE_STRING, 'validate' => 'isGenericName', 'required' => true, 'size' => '255'),
            'replaceby' => array('type' => self::TYPE_STRING, 'validate' => 'isGenericName', 'required' => true, 'size' => '255')
        )
    );

    public static function getAll()
    {
        return Db::getInstance()->executeS('SELECT * FROM `' . _DB_PREFIX_ . 'mytable`');
    }
}

but i don't get how i'm suppose to adapt that i think it's with the model but every documentation i found about it only talk about what is it use for or talk aout function construct and other can someone explain me or redirect me to a good post about it pls.

      {

        /**
         * Constructor
         *
         * @param \Magento\Backend\App\Action\Context $context
         * @param \Magento\Framework\View\Result\PageFactory $resultPageFactory
         */
        public function __construct(
            \Magento\Backend\App\Action\Context $context,
            \Magento\Framework\View\Result\PageFactory $resultPageFactory
        ) {
             parent::__construct($context);
             $this->resultPageFactory = $resultPageFactory;
        }
        
        public function execute()
        {

    }
    
}

pls help i'm losing hope i'm only redirect to a blank page with "test" write in the middle but without my new data in the table

Re: Magento 2 Class in Module

MyModule/AdminPage/Model/Contact.php

 

 

<?php

namespace MyModule\AdminPage\Model;
use Magento\Framework\Model\AbstractModel;
class Contact extends AbstractModel
{
	/**
     * Define resource model
     */
   protected function _construct()
    {
        $this->_init('MyModule\AdminPage\Model\ResourceModel\Contact');
    }	
	
}

then i have i have MyModule/AdminPage/Model/ResourceModel/Contact.php

 

Make sure id as primary key.

 

Controller file:

 

 $contact = $this->_objectManager->create('MyModule\AdminPage\Model\Contact');
$data =[];
$data['toreplace']="test1";
$data['replaceby']="test1";
$contact->setData($data);
$contact->save()

Make sure var/generation removed and cache flush.

Re: Magento 2 Class in Module

After a 50th try i saw a double / at one place and the primary key was "Id" and not "id" that was making everything failed very sorry for having bored you with that it all work now thanks you all.
