Adds ability do declare entity discriminator map using a configuration.

Installation

$ composer require facile-it/doctrine-dynamic-discriminator-map 

Register the listener on Doctrine Event Manager

Example:

<?php use Doctrine\Common\EventManager; use Doctrine\ORM\EntityManager; use Doctrine\ORM\Tools\Setup; use Facile\DoctrineDDM\Factory\MetadataConfigFactory; use Facile\DoctrineDDM\MetadataListener; use My\Namespace\Entity; $metadataConfigFactory = new MetadataConfigFactory(); // discriminator map configuration $metadataConfig = $metadataConfigFactory->createMetadata([ Entity\Person::class => [ // parent class 'discriminator_map' => [ 'teacher' => Entity\Teacher::class, // child class 'student' => Entity\Student::class, // child class ], ], ]); $metadataListener = new MetadataListener($metadataConfig); $eventManager = new EventManager(); $eventManager->addEventSubscriber($metadataListener); $config = Setup::createAnnotationMetadataConfiguration( [__DIR__ . '/src'], true, null, null, false ); $connection = [ 'driver' => 'pdo_sqlite', 'memory' => true, ]; $entityManager = EntityManager::create($connection, $config, $eventManager);

Entities

Create the parent entity:

<?php namespace My\Namespace\Entity; use Doctrine\ORM\Mapping as ORM; /**  * @ORM\Entity  * @ORM\Table(name="person")  * @ORM\InheritanceType("SINGLE_TABLE")  * @ORM\DiscriminatorColumn(name="type", type="string")  * @ORM\DiscriminatorMap({"person" = "Person"})  */ class Person { // ... }

Then you can declare the children entities:

<?php namespace My\Namespace\Entity; use Doctrine\ORM\Mapping as ORM; /**  * @ORM\Entity  */ class Student extends Person { // ... } /**  * @ORM\Entity  */ class Teacher extends Person { // ... }

That's it!

Frameworks Integration

Invokable factories

Facile\DoctrineDDM\Factory\MetadataConfigFactory and Facile\DoctrineDDM\Factory\MetadataListenerFactory have an __invoke() method that can be used with Interop\Container\ContainerInterface.

Facile\DoctrineDDM\Factory\MetadataConfigFactory will check for a config key where expects an array configuration.
Then it will check for Facile\DoctrineDDM\Factory\MetadataConfigFactory::CONFIG_KEY key where it expects the discriminator map configuration and returns a Facile\DoctrineDDM\Configuration\Metadata instance.

Facile\DoctrineDDM\Factory\MetadataListenerFactory will check for a service named Facile\DoctrineDDM\Configuration\Metadata (the configuration class) then will return a configured Facile\DoctrineDDM\MetadataListener instance.

Zend Framework and Zend Expressive

With DoctrineORMModule:

use Facile\DoctrineDDM\MetadataListener; use Facile\DoctrineDDM\Factory\MetadataConfigFactory; use Facile\DoctrineDDM\Factory\MetadataListenerFactory; use Facile\DoctrineDDM\Configuration\Metadata; use My\Namespace\Entity; return [ 'service_manager' => [ // or "dependencies" for zend-expressive 'factories' => [ // register the configuration factory Metadata::class => MetadataConfigFactory::class, // register the metadata listener factory MetadataListener::class => MetadataListenerFactory::class, ], ], 'doctrine' => [ 'eventmanager' => [ 'orm_default' => [ 'subscribers' => [ // register MetadataListener MetadataListener::class, ], ], ], ], // declare discriminator map configuration used by MetadataConfigFactory MetadataConfigFactory::class => [ Entity\Person::class => [ // parent class 'discriminator_map' => [ 'teacher' => Entity\Teacher::class, // child class 'student' => Entity\Student::class, // child class ], ], ], ];
