How to configure a fixture factoryΒΆ

First you have to create a fixture factory. This service is responsible to create new instance of the resource and handle options. This allows to combine random and custom data on your data fixtures.

namespace App\Fixture\Factory;

use App\Entity\Article;
use Monofony\Plugin\FixturesPlugin\Fixture\Factory\AbstractExampleFactory;
use Sylius\Component\Resource\Factory\FactoryInterface;
use Symfony\Component\OptionsResolver\Options;
use Symfony\Component\OptionsResolver\OptionsResolver;

final class ArticleExampleFactory extends AbstractExampleFactory
{
    /** @var FactoryInterface */
    private $articleFactory;

    /** @var \Faker\Generator */
    private $faker;

    /** @var OptionsResolver */
    private $optionsResolver;

    public function __construct(FactoryInterface $articleFactory)
    {
        $this->articleFactory = $articleFactory;

        $this->faker = \Faker\Factory::create();
        $this->optionsResolver = new OptionsResolver();

        $this->configureOptions($this->optionsResolver);
    }

    /**
     * {@inheritdoc}
     */
    protected function configureOptions(OptionsResolver $resolver): void
    {
        $resolver
            ->setDefault('title', function (Options $options) {
                return ucfirst($this->faker->words(3, true));
            });
    }

    /**
     * {@inheritdoc}
     */
    public function create(array $options = []): Article
    {
        $options = $this->optionsResolver->resolve($options);

        /** @var Article $article */
        $article = $this->articleFactory->createNew();
        $article->setTitle($options['title']);

        return $article;
    }
}

Thanks to services configuration, your new service is already registered and ready to use:
