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()
{
// ...
}
}
