My 2 entites, i want count how many Wardrobes is related for each magazines, i must make this from querybuilder
$em = $this->get('doctrine.orm.entity_manager');
$userRepository = $em->getRepository('Raltech\WarehouseBundle\Entity\Magazine');
$qb = $userRepository->createQueryBuilder('magazine')
->addSelect("magazine.id,magazine.name,magazine.description")
->InnerJoin('magazine.wardrobe', 'wardrobe')
->addSelect('COUNT(wardrobe.id) AS wardrobecount')
This didn't work of course.
So, somebody can me provide example how to count this from querybuilder?

Answer 1

Summarising the comments:
$qb = $userRepository->createQueryBuilder('magazine')
->addSelect("magazine.id,magazine.name,magazine.description")
->leftJoin('magazine.wardrobe', 'wardrobe') // To show as well the magazines without wardrobes related
->addSelect('COUNT(wardrobe.id) AS wardrobecount')
->groupBy('magazine.id'); // To group the results per magazine
