I would like to extend Entity\\Base classes, how to do this in Doctrine 2.1? My research showed that whenever someone encounters the problem with doing this he switches to Doctrine 1.2 :)n I am using yaml configuration
Doctrine 2.X Entities work as POPOs (Plain Old PHP Objects). To achieve extending correctly, Doctrine enforces you to use a concept from JPA called Mapped Super Classes. The idea is pretty simple. Whenever you want to have a base class and want your entities to extend from it (I'm not talking about inheritance at DB level), all you need to do is create your Base class as a MappedSuperClass.
Here is an example: http://www.doctrine-project.org/docs/orm/2.1/en/reference/inheritance-mapping.html#mapped-superclasses
Thanks
Here the solution from Guilherme Blanco link. I like to have a posted solution instead of a link which eventually could no longer work in future:
<?php
/** @MappedSuperclass */
class MappedSuperclassBase
{
/** @Column(type="integer") */
protected $mapped1;
/** @Column(type="string") */
protected $mapped2;
/**
* @OneToOne(targetEntity="MappedSuperclassRelated1")
* @JoinColumn(name="related1_id", referencedColumnName="id")
*/
protected $mappedRelated1;
// ... more fields and methods
}
/** @Entity */
class EntitySubClass extends MappedSuperclassBase
{
/** @Id @Column(type="integer") */
private $id;
/** @Column(type="string") */
private $name;
// ... more fields and methods
}
