[FLOW3-general] inheritance and repositories

[Steffen Wickham]

Hey Mathis,

I'm sorry, I assumed you already tagged your base class correctly. My
mistake, sorry!

You have to add some annotations for your base class (AbstractAssignment
for me), so Doctrine/DBAL can create the right scheme. That's how I
annotate my base class:

<?php
namespace AFSVN\Basic\Domain\Model;

use Doctrine\ORM\Mapping as ORM;
use TYPO3\Flow\Annotations as Flow;

/**
 * @Flow\Entity
 * @ORM\InheritanceType("JOINED")
 */
abstract class AbstractAssignment {
    ... (all shared values goes here) ...
}
?>


So Doctrine creates a afsvn_basic_domain_model_abstractassignment table
with your shared values and a column "dtype", which holds a string
representation of you derived class, e.g. afsvn_basic_refereeassignment.
In the "afsvn_basic_domain_model_refereeassignment" table it use the
same identifier as the abstract table and holds only the
refereeassignment specific data. When you try to access an object by the
created repository, doctrine joins all data correctly, whether which
concrete class has been fetched.

Yours
Steffen
