Attributes for Laravel

Attach dynamic, typed key/value attributes to any Eloquent model through one polymorphic table: no schema change per attribute, no EAV boilerplate. Values keep their real PHP type, an optional registry validates them, and query scopes filter owners by their attributes.

Installation

Requires PHP 8.4 and Laravel 12 or 13.

composer require roundly-consulting/attributes-for-laravel
php artisan vendor:publish --tag="attributes-migrations"
php artisan migrate

If your owner models have UUID/ULID keys, set ATTRIBUTES_KEY_TYPE before migrating.

Usage

Add the trait and its contract to any model:

use Illuminate\Database\Eloquent\Model;
use RoundlyConsulting\Attributes\Contracts\HasAttributes as HasAttributesContract;
use RoundlyConsulting\Attributes\Traits\HasAttributes;

class Product extends Model implements HasAttributesContract
{
    use HasAttributes;
}

Then write, read and query typed attributes (definitions are optional):

use RoundlyConsulting\Attributes\DataTransferObjects\AttributeDefinitionData;
use RoundlyConsulting\Attributes\Enums\AttributeType;
use RoundlyConsulting\Attributes\Facades\Attributes;

Attributes::define(new AttributeDefinitionData(
    name: 'rating',
    type: AttributeType::Integer,
    rules: ['min:1', 'max:5'],
));

Attributes::for($product)->set('color', 'red', meta: ['hex' => '#f00']);
Attributes::for($product)->setMany(['rating' => '5', 'on_sale' => true]);   // '5' is stored as 5

Attributes::for($product)->get('rating');     // 5
Attributes::for($product)->toKeyValue();      // ['color' => 'red', 'rating' => 5, 'on_sale' => true]
Attributes::for($product)->set('rating', 9);  // throws InvalidAttributeValueException

Product::query()->whereAttribute('color', 'red')->whereAttributeBetween('rating', 4, 5)->get();
