Extends ServiceEntityRepository instead of EntityRepository

[fclausset]

In the day 6, with SF 4, we could extend ServiceEntityRepository for the repositories as per the symfony doc

It allows you to use autowiring and thus less boiler plate.

use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Doctrine\Common\Persistence\ManagerRegistry;

class CategoryRepository extends ServiceEntityRepository
{
    public function __construct(ManagerRegistry $registry)
    {
        parent::__construct($registry, Category::class);
    }
...
}

and then in the JobController

use App\Repository\CategoryRepository;
...

public function list(CategoryRepository $categoryRepository) : Response
{
    $categories = $categoryRepository->findWithActiveJobs();

    return $this->render('job/list.html.twig', [
            'categories' => $categories,
     ]);
}

Anyway it also works with EntityRepository.

Thanks for the great Job.
