[DDC-2370] Subclass annotations not being read, unable to use OneToMany relation with single table inheritance

Wed, 1 May 2013 19:18:25 +0000

Subclasses that override parent class properties and define relations will not work as expected, because AnnotationDriver/Reader will only use the parent class annotation (discarding whatever subclass defined).

The following code will produce error:

[Mapping]  FAIL - The entity-class 'Test\Office' mapping is invalid:
* The mappings Test\Office#employees and Employee#office are incosistent with each other.

Test code:

<?php
namespace Test;
 
use Doctrine\ORM\Mapping as ORM;
 
/**
 * @ORM\Entity
 */
class Office 
{
    /**
     * @ORM\OneToMany(targetEntity="Person", mappedBy="office")
     * @var Person[]|ArrayCollection
     */
    protected $people;
 
    /**
     * @ORM\OneToMany(targetEntity="Employee", mappedBy="office")
     * @var Employee[]|ArrayCollection
     */
    protected $employees;
 
}
 
/**
 * @ORM\Entity
 * @ORM\InheritanceType("SINGLE_TABLE")
 * @ORM\DiscriminatorColumn(name="type", type="string")
 * @ORM\DiscriminatorMap({"employee" = "Employee"})
 */
class Person
{
    /**
     * @ORM\ManyToOne(targetEntity="Office", inversedBy="people")
     * @var Office
     */
    protected $office;
}
 
/**
 * @ORM\Entity
 */
class Employee extends Person
{
    /**
     * @ORM\ManyToOne(targetEntity="Office", inversedBy="employees")
     * @var Office
     */
    protected $office;
}
