Vendor promotions

The vendors can create their own promotions and configure the rules. This feature is disabled by default, however, it can be enabled.

1. Add the enabled configuration parameter

# config/packages/odiseo_sylius_marketplace.yaml
odiseo_sylius_marketplace:
    vendor_promotion_enabled: true

2. Include traits and override the resources

Use Odiseo\SyliusMarketplacePlugin\Entity\VendorAwareTrait, not the vendor plugin's VendorTrait — VendorTrait is Product-specific (a required, bidirectional association back to Vendor::$products via inversedBy: 'products'), which doesn't apply to Promotion.

<?php
// src/Entity/Promotion.php

declare(strict_types=1);

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Odiseo\SyliusMarketplacePlugin\Entity\VendorAwareTrait;
use Odiseo\SyliusVendorPlugin\Entity\VendorAwareInterface;
use Sylius\Component\Core\Model\Promotion as BasePromotion;

#[ORM\Entity]
#[ORM\Table(name: 'sylius_promotion')]
class Promotion extends BasePromotion implements VendorAwareInterface
{
    use VendorAwareTrait;
}

<?php
// src/Repository/PromotionRepository.php

declare(strict_types=1);

namespace App\Repository;

use Odiseo\SyliusMarketplacePlugin\Repository\PromotionRepositoryInterface;
use Odiseo\SyliusMarketplacePlugin\Repository\PromotionRepositoryTrait;
use Sylius\Bundle\CoreBundle\Doctrine\ORM\PromotionRepository as BasePromotionRepository;

class PromotionRepository extends BasePromotionRepository implements PromotionRepositoryInterface
{
    use PromotionRepositoryTrait;
}

The seller panel also scopes promotion coupons to the owning vendor, so the coupon repository needs the same treatment:

<?php
// src/Repository/PromotionCouponRepository.php

declare(strict_types=1);

namespace App\Repository;

use Odiseo\SyliusMarketplacePlugin\Repository\PromotionCouponRepositoryInterface;
use Odiseo\SyliusMarketplacePlugin\Repository\PromotionCouponRepositoryTrait;
use Sylius\Bundle\PromotionBundle\Doctrine\ORM\PromotionCouponRepository as BasePromotionCouponRepository;

class PromotionCouponRepository extends BasePromotionCouponRepository implements PromotionCouponRepositoryInterface
{
    use PromotionCouponRepositoryTrait;
}

# config/packages/_sylius.yaml
sylius_promotion:
    resources:
        promotion:
            classes:
                repository: App\Repository\PromotionRepository
        promotion_coupon:
            classes:
                repository: App\Repository\PromotionCouponRepository

3. Create the database migration and apply it to your database

The vendor_id column on sylius_promotion is not part of the plugin's shipped migrations — this feature is opt-in, so the column only exists once you enable it. Generate the migration yourself, review it, then apply it:

php bin/console doctrine:migrations:diff
php bin/console doctrine:migrations:migrate
