Doctrine ULID generator

This small library adds support for ULID in Doctrine.

ULIDs act like UUIDs that can be lexicographically sorted. ULIDs also have a smaller footprint (26 ANSI characters vs. 36 for UUIDs);

This package integrates robinvdvleuten/ulid as a CustomIdGenerator.

Installation

composer require bentools/doctrine-ulid

Usage

Use the provided class as a custom ID generator:

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity()
 */
class Foo
{

    /**
     * @var string
     *
     * @ORM\Id()
     * @ORM\GeneratedValue(strategy="CUSTOM")
     * @ORM\CustomIdGenerator(class="\BenTools\ULIDGenerator")
     * @ORM\Column(type="string", length=26)
     */
    private $id;
    
    // ...
    
}

Or use the following trait:

use Doctrine\ORM\Mapping as ORM;
use BenTools\GeneratedULIDTrait;

/**
 * @ORM\Entity()
 */
class Foo
{

    use GeneratedULIDTrait;
    
    // ... 
    
}

If you want to set ULIDs by yourself (this way, they can be generated on the client side), use the EditableULIDTrait which will expose a setId() method:

use Doctrine\ORM\Mapping as ORM;
use BenTools\EditableULIDTrait;

/**
 * @ORM\Entity()
 * @ORM\HasLifecycleCallbacks()
 */
class Foo
{

    use EditableULIDTrait;
    
    // ... 
    
}

• If setId() is not called, an ULID will be automatically generated on persist.
• Don't forget to add a @HasLifecycleCallbacks() annotation on top of your entity for this behavior to work properly.
