Doctrine Behaviors


This PHP library is a collection of traits and interfaces that add behaviors to Doctrine entities and repositories.

It currently handles:


composer require knplabs/doctrine-behaviors


All you have to do is to define a Doctrine entity:

  • implemented interface
  • add a trait

For some behaviors like tree, you can use repository traits:



namespace App\Repository;

use Doctrine\ORM\EntityRepository;
use Knp\DoctrineBehaviors\ORM\Tree\TreeTrait;

final class CategoryRepository extends EntityRepository
    use TreeTrait;


You now have a working Category that behaves like.


A PHPStan extension is available and provides the following features:

  • Provides correct return type for TranslatableInterface::getTranslations() and TranslatableInterface::getNewTranslations()
  • Provides correct return type for TranslatableInterface::translate()
  • Provides correct return type for TranslationInterface::getTranslatable()

Include phpstan-extension.neon in your project's PHPStan config:

# phpstan.neon
    - vendor/knplabs/doctrine-behaviors/phpstan-extension.neon
