Some Doctrine 2 Extensions

This package contains several extensions to Doctrine 2 that hook into the facilities of Doctrine and offer new functionality or tools to use Doctrine 2 more efficently.

Including DoctrineExtensions

To include the DoctrineExtensions should fire up an autoloader, for example:


$classLoader = new \Doctrine\Common\ClassLoader('DoctrineExtensions', "/path/to/extensions");


The paginator offers a powerful way to iterate over any DQL, even fetch joins of collections. For this it has to issue 3 queries to the database:

  1. Count the total number of entries in the list
  2. Fetch the Unique IDs of the given $limit + $offset window
  3. Fetch the Entities for all the Unique Ids given in 2.

If you don't need to iterate a fetch-joined to-many DQL query you can shortcut:

  1. Count the total number of entries in the list
  2. Fetch the Query using $query->setFirstResult($offset)->setMaxResults($limit);

The API for the Paginator is really simple:


use DoctrineExtensions\Paginate\Paginate;

$query = $em->createQuery($dql);

$count = Paginate::getTotalQueryResults($query); // Step 1
$paginateQuery = Paginate::getPaginateQuery($query, $offset, $limitPerPage); // Step 2 and 3
$result = $paginateQuery->getResult();

In the simple case its even easier:


$count = Paginate::getTotalQueryResults($query); // Step 1
$result = $query->setFirstResult($offset)->setMaxResults($limitPerPage)->getResult(); // Step 2

These methods internally use several others to create and retrieve the data. You can re-use those methods to integrate with existing pagination solutions, a Zend_Paginator implementation is already shipped (DoctrineExtensions\Paginate\PaginationAdapter).


The PHPUnit Extension for Doctrine offers several hooks into PHPUnits Database extension and offers a very convenient way to test your Doctrine 2 code against a Database.

Using the OrmTestCase:

An Example


namespace MyProject\Tests;

use DoctrineExtensions\PHPUnit\OrmTestCase

class EntityFunctionalTest extends OrmTestCase
    protected function createEntityManager()
        return Doctrine\ORM\EntityManager::create(..);

    protected function getDataSet()
        return $this->createFlatXmlDataSet(__DIR__."/_files/entityFixture.xml");

For more information see the PHPUnit Documentation on this topic:


This PHPUnit extension does not create the database schema for you. It has to be created before you run the tests. If you want to dynamically create the schema you have to listen to the 'preTestSetUp' and 'postTestSetUp' events that are called before and after the fixture is loaded respectively.


namespace MyProject\Tests;

use DoctrineExtensions\PHPUnit\Event\EntityManagerEventArgs,

class SchemaSetupListener
    public function preTestSetUp(EntityManagerEventArgs $eventArgs)
        $em = $eventArgs->getEntityManager();

        $schemaTool = new SchemaTool($em);

        $cmf = $em->getMetadataFactory();
        $classes = $cmf->getAllMetadata();


class EntityFunctionalTest extends OrmTestCase
    protected function createEntityManager()
        $eventManager = new EventManager();
        $eventManager->addEventListener(array("preTestSetUp"), new SchemaSetupListener());

        return Doctrine\ORM\EntityManager::create(.., $eventManager);


  • Add a Filter to transform between Entity-Speak and database columns for the DataSet and DataTable interfaces. This could also be used as basis for "fixture" management. XML or YAML fixture formats could be used to fill the database initially.
  • Add a test-case that automatically tests the persistence of all your entities against the current mapping schema and database, aswell as related entities.


Deprecated, please use


Versionable allows you to tag your entities by the DoctrineExtensions\Versionable\Versionable interface, which leads to snapshots of the entities being made upon saving to the database.

This is an extended version of the prototype discussed in a blog-post on the Doctrine 2 website:

The interface Versionable is modified considerably by removing all the getResourceId(), getVersionedData() and getCurrentVersion() methods, since Doctrine can easily retrieve these values on its own using the UnitOfWork API. Versionable is then just a marker interface.

What Versionable does

Whenever an entity that implements Versionable is updated all the old values of the entity are saved with their old version number into a newly created ResourceVersion entity.

Requirements of your entities are:

  • Single Identifier Column (String or Integer)
  • Entity has to be versioned (using @version annotation)

Implementing Versionable would look like:


namespace MyProject;
use DoctrineExtensions\Versionable\Versionable;

class BlogPost implements Versionable
    // blog post API


You have to add the DoctrineExtensions\Versionable\Entity\ResourceVersion entity to your metadata paths. It is using the Annotation Metadata driver, so you have to specifiy or configure the path to the directory on the CLI. Also if you are using any other metadata driver you have to wrap the Doctrine\ORM\Mapping\Driver\DriverChain to allow for multiple metadata drivers.

You also have to hook the VersionListener into the EntityManager's EventManager explicitly upon construction:


$eventManager = new EventManager();
$eventManager->addEventSubscriber(new VersionListener());
$em = EntityManager::create($connOptions, $config, $eventManager);

Using the VersionManager you can now retrieve all the versions of a versionable entity:


$versionManager = new VersionManager($em);
$versions = $versionManager->getVersions($blogPost);

Or you can revert to a specific version number:


$versionManager = new VersionManager($em);
$versionManager->revert($blogPost, 100);
