Use ramsey/uuid as a Doctrine field type

The ramsey/uuid-doctrine package provides the ability to use ramsey/uuid as a Doctrine field type.

This project adheres to a code of conduct. By participating in this project and its community, you are expected to uphold this code.

Installation

Install this package as a dependency using Composer.

composer require ramsey/uuid-doctrine

Usage

Configuration

To configure Doctrine to use ramsey/uuid as a field type, you'll need to set up the following in your bootstrap:

\Doctrine\DBAL\Types\Type::addType('uuid', 'Ramsey\Uuid\Doctrine\UuidType');

In Symfony:

# config/packages/doctrine.yaml
doctrine:
    dbal:
        types:
            uuid: Ramsey\Uuid\Doctrine\UuidType

In Zend Framework:

 [
        'configuration' => [
            'orm_default' => [
                'types' => [
                    UuidType::NAME => UuidType::class,

In Laravel:

 [
        \Ramsey\Uuid\Doctrine\UuidType::NAME => \Ramsey\Uuid\Doctrine\UuidType::class
    ],

In roave/psr-container-doctrine:

 [
        'types' => [
            UuidType::NAME => UuidType::class,
        ],
        /* ... */
    ],
    /* ... */
];

Mappings

Then, in your models, you may annotate properties by setting the #[Column] type to uuid, and defining a custom generator of Ramsey\Uuid\UuidGenerator. Doctrine will handle the rest.

use Doctrine\ORM\Mapping as ORM;
use Ramsey\Uuid\Doctrine\UuidGenerator;
use Ramsey\Uuid\UuidInterface;

#[ORM\Entity]
#[ORM\Table(name: "products")]
class Product
{
    #[ORM\Id]
    #[ORM\Column(type: "uuid", unique: true)]
    #[ORM\GeneratedValue(strategy: "CUSTOM")]
    #[ORM\CustomIdGenerator(class: UuidGenerator::class)]
    protected UuidInterface $id;

    public function getId(): UuidInterface
    {
        return $this->id;
    }
}

If you use the XML Mapping instead of PHP attributes.

You can also use the YAML Mapping.

id:
    id:
        type: uuid
        generator:
            strategy: CUSTOM
        customIdGenerator:
            class: Ramsey\Uuid\Doctrine\UuidGenerator

Binary database columns

In the previous example, Doctrine will create a database column of type CHAR(36) if MariaDB / MySQL are in use, but you may also use this library to store UUIDs as binary strings. The UuidBinaryType helps accomplish this.

In your bootstrap, place the following:

\Doctrine\DBAL\Types\Type::addType('uuid_binary', 'Ramsey\Uuid\Doctrine\UuidBinaryType');
$entityManager->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary', 'binary');

In Symfony:

# config/packages/doctrine.yaml
doctrine:
    dbal:
        types:
            uuid_binary:  Ramsey\Uuid\Doctrine\UuidBinaryType
# Uncomment if using doctrine/orm getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary_ordered_time', 'binary');

In Symfony:

# config/packages/doctrine.yaml
doctrine:
   dbal:
       types:
           uuid_binary_ordered_time: Ramsey\Uuid\Doctrine\UuidBinaryOrderedTimeType
# Uncomment if using doctrine/orm id;
   }
}

If you use the XML Mapping instead of PHP annotations.

InnoDB-optimised binary UUIDs - new way

With the introduction of new UUID types (including sortable, unix epoch based UUID version 7) it is now recommended to use regular uuid_binary with Ramsey\Uuid\Doctrine\UuidV7Generator for primary keys.

In your bootstrap, place the following:

\Doctrine\DBAL\Types\Type::addType('uuid_binary', 'Ramsey\Uuid\Doctrine\UuidBinaryType');
$entityManager->getConnection()->getDatabasePlatform()->registerDoctrineTypeMapping('uuid_binary', 'binary');

In Symfony:

# config/packages/doctrine.yaml
doctrine:
    dbal:
        types:
            uuid_binary:  Ramsey\Uuid\Doctrine\UuidBinaryType
# Uncomment if using doctrine/orm id;
    }
}

If you use the XML Mapping instead of PHP annotations.

PostgreSQL considerations

If you are using PostgreSQL, Doctrine uses PostgreSQL's uuid for the Ramsey\Uuid\Doctrine\UuidType (uuid). Therefor you don't need to use the uuid_binary / uuid_binary_ordered_time types when using PostgreSQL. You can still use UuidV7Generator::class to optimize indexing though.

#[Entity]
#[Table(name: "products")]
class Product
{
    #[Id]
    #[Column(type: "uuid", unique: true)]
    #[GeneratedValue(strategy: "CUSTOM")]
    #[CustomIdGenerator(class: UuidV7Generator::class)]
    protected UuidInterface $id;

    public function getId(): UuidInterface
    {
        return $this->id;
    }
}

Working with binary identifiers

When working with binary identifiers you may wish to convert them into a readable format. As of MySql 8.0 you can use the BIN_TO_UUID and UUID_TO_BIN functions documented here. The second argument determines if the byte order should be swapped, therefore when using uuid_binary you should pass 0 and when using uuid_binary_ordered_time you should pass 1.

For other versions you can use the following:
