Symfony2 MappedSuperClass and doctrine:generate:entities

Question

I have a "Offer" class (MapperSuperclass) and 2 more classes extending it, "PrivateOffer" and "PublicOffer".

The problem I have is, when I run "doctrine:generate:entities" command, both classes "PrivateOffer" and "PublicOffer" are fullfilled with the same properties than the MappedSuperclass "Offer" class, and also it's getter and setter methods.

If I remove them and live them only in the "Offer" class, the "doctrine:schema:update" works well as expected, but I need to run the "doctrine:generate:entities" again so, it ruins everytime my extended classes.

Why is the "doctrine:generate:entities" duplicating all the properties and setter/getter methods in both of the classes, if they extends the MappedSupperclass?

Thank you all :)

OfferClass:

namespace Pro\JobBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
/**
 * Offer
 *
 * @ORM\MappedSuperclass()
 */
class Offer
{
    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255)
     */
    protected $name;

    ....more properties...
}

PrivateOfferClass:

<?php

namespace Pro\JobBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * PrivateOffer
 *
 * @ORM\Table(name="private_offer")
 * @ORM\Entity
 */
class PrivateOffer extends Offer
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;


    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }
}

PublicOfferClass:

<?php

namespace Pro\JobBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * PublicOffer
 *
 * @ORM\Table(name="public_offer")
 * @ORM\Entity
 */
class PublicOffer extends Offer
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;


    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }
}

This is a known behaviour (not to say: bug) in Doctrine: In your scenario, all entity properties must be private. Accessing them must only be possible via the getters.

Changed all properties from protected to private in the "Offer" class and problem solved. Thank you very much lxg!! :) – Row

Can you please provide more details on this? Why is that so? :) – Plosive

Basically, child classes can override public and protected properties. That's why they are not processed when a mapped superclass is evaluated. You can find a more detailed explanation at github.com/doctrine/mongodb-odm/issues/918 (it's for the Doctrine ODM but the same applies to the ORM). – Merodach
