ltree-bundle

Installation:

composer require pvsaintpe/ltree-bundle

Using

1. Create Entity class:

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\ORM\Mapping\Entity;
use LTree\Annotation\LTreeChilds;
use LTree\Annotation\LTreeEntity;
use LTree\Annotation\LTreeParent;
use LTree\Annotation\LTreePath;
use LTree\Repository\LTreeEntityInterface;

/**
 * Class TestEntity
 * @package LTree\Entity
 *
 * @Entity(repositoryClass="LTree\Entity\TestRepository")
 * @LTreeEntity()
 */
class TestEntity implements LTreeEntityInterface
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @LTreePath()
     * @ORM\Column(type="ltree")
     */
    private $path = null;

    /**
     * @LTreeParent()
     * @ORM\ManyToOne(targetEntity="TestEntity", inversedBy="children")
     * @ORM\JoinColumn(name="parent_id", referencedColumnName="id")
     */
    private $parent;

    /**
     * @LTreeChilds()
     * @ORM\OneToMany(targetEntity="TestEntity", mappedBy="parent", cascade={"all"}, orphanRemoval=true)
     * @ORM\JoinColumn(onDelete="CASCADE")
     */
    private $children;

    /**
     * Constructor
     */
    public function __construct()
    {
        $this->children = new ArrayCollection();
    }
}

2. Create Repository class:

use Doctrine\ORM\EntityManagerInterface;
use LTree\Repository\LTreeEntityRepository;

/**
 * Class TestRepository
 *
 * @method TestEntity|null find($id, $lockMode = null, $lockVersion = null)
 * @method TestEntity|null findOneBy(array $criteria, array $orderBy = null)
 * @method TestEntity[]    findAll()
 * @method TestEntity[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
 *
 * @package LTree\Entity
 */
class TestRepository extends LTreeEntityRepository
{
    /**
     * TestRepository constructor.
     * @param EntityManagerInterface $registry
     */
    public function __construct(EntityManagerInterface $registry)
    {
        parent::__construct($registry, $registry->getClassMetadata(TestEntity::class));
    }
}

3. Create Extension via migration

    public function up(Schema $schema) : void
    {
        $this->addSql('CREATE IF NOT EXISTS EXTENSION ltree');
    }
    ...

4. Configure Doctrine Type via config (packages/doctrine.yaml):

doctrine:
    dbal:
        url: '%env(resolve:DATABASE_URL)%'
        types:
            ltree:  LTree\Types\LTreeType

5. Configure Bundle via config (bundles.php):

LTree\LTreeExtensionBundle::class => ['all' => true],
