README
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 ], ], ], ];
