• doctrine/orm: ^3

README

locky42/leopard-doctrine integrates Doctrine ORM with Leopard events and provides a registry for ResolveTargetEntity mappings.

Features

• Global wrapper around Doctrine EntityManager (Leopard\Doctrine\EntityManager)
• ResolveTargetEntityRegistry for interface → implementation mappings
• Event-based initialization hooks:
  • BeforeInitEventManagerEvent
  • AfterInitEventManagerEvent
  • BeforeInitEntityManagerEvent
  • AfterInitEntityManagerEvent

Installation

composer require locky42/leopard-doctrine

Usage

1) Configure mappings (optional)

Register interface mappings before BeforeInitEntityManagerEvent is dispatched:

use Leopard\Doctrine\ResolveTargetEntityRegistry;
use Leopard\User\Contracts\Models\UserInterface;
use App\Models\User;

ResolveTargetEntityRegistry::addResolveTargetEntity(
    UserInterface::class,
    User::class,
    []
);

2) Initialize Doctrine and Leopard events

use Doctrine\Common\EventManager as DoctrineEventManager;
use Doctrine\DBAL\DriverManager;
use Doctrine\ORM\EntityManager as ORMEntityManager;
use Doctrine\ORM\ORMSetup;
use Leopard\Doctrine\EntityManager;
use Leopard\Doctrine\Events\BeforeInitEntityManagerEvent;
use Leopard\Doctrine\Events\BeforeInitEventManagerEvent;
use Leopard\Doctrine\Events\AfterInitEventManagerEvent;
use Leopard\Events\EventManager as LeopardEventManager;

$config = ORMSetup::createAttributeMetadataConfiguration(
    paths: [__DIR__ . '/src/Models'],
    isDevMode: true
);

LeopardEventManager::doEvent(BeforeInitEventManagerEvent::class);

$eventManager = new DoctrineEventManager();

LeopardEventManager::doEvent(AfterInitEventManagerEvent::class, $eventManager);

$connection = DriverManager::getConnection([
    // driver, host, dbname, user, password...
], null, $eventManager);

LeopardEventManager::doEvent(BeforeInitEntityManagerEvent::class);

// Important: pass the same Doctrine EventManager to ORM EntityManager
$ormEntityManager = new ORMEntityManager($connection, $config, $eventManager);

EntityManager::setEntityManager($ormEntityManager);

3) Retrieve EntityManager anywhere

$em = EntityManager::getEntityManager();

Requirements

• PHP 8.3+
• Doctrine ORM 3.x
• locky42/leopard-events

Notes

• If you use ResolveTargetEntity, ensure listeners are attached to the same Doctrine EventManager instance that is passed to ORM EntityManager.
• The package bootstrap auto-registers internal listeners via Composer autoload files.
