加载后实体的自定义列

Question

I have an entity,

// src/Acme/StoreBundle/Entity/Product.php
namespace Acme\StoreBundle\Entity;

class Product
{
    protected $name;
    protected $price;
    protected $description;
}

I when I get a product record I want to join the name and description. Something like,

// src/Acme/StoreBundle/Entity/Product.php
namespace Acme\StoreBundle\Entity;

class Product
{
    protected $name;
    protected $price;
    protected $description;
    protected $heading;

    public function __construct()
    {
        parent::__construct();

        $this->heading = $this->name . ' ' . $this->description;
    }
}

I've tried setting heading on the preLoad event, in the constructor. After its creation and before serialising. Nothing seems to work. How can I do this?

You can try to use just getter:

public function getHeading()
{
    return $this->name . ' ' . $this->description;
}
