Creating Models

Model is a class that extends Phalcon\Mvc\Model. In creating models, initialize() method is used which is called only once during the request.

<?php
namespace Phalcon\Tutorial;
use Phalcon\Mvc\Model;
class CarPrice extends Model
{
    public function initialize()
    {
        $this->setSource(car_price');
    }
}
?>

But if we want to perform initialize task for every instance we uses onConstruct() method.

<?php

namespace Phalcon\Tutorial;

use Phalcon\Mvc\Model;

class CarPrice extends Model
{
    public function onConstruct()
    {
        // ...
    }
}
