How to get foreign repository inside my repository in Doctrine2/Symfony2?

Question

I need values from 2 different entities. I don\'t know how to do. I tried this so far:

Answer 1

If you like more to inject dependencies, declare your repositories as services so you can inject one to use it inside the other:

services.yml

services:
    repository.user_lake:
        class: Pond\GeolocBundle\Entity\UserLakeRepository
        factory: [@doctrine, getRepository]
        arguments:
            - PondGeolocBundle:User_Lake

    repository.pond_lake:
        class: Pond\GeolocBundle\Entity\PondLakeRepository
        factory: [@doctrine, getRepository]
        arguments:
            - PondGeolocBundle:PondLake
        calls:
            - [setUserLakeRepository, [@repository.user_lake]]

in PondLakeRepository.php you must have a setter (setUserLakeRepository) to a property to store the repository (i.e. $userLakeRepository).

Answer 2

You can access the EntityManager by calling Doctrine\ORM\EntityRepository#getEntityManager():

$repository = $this
    ->getEntityManager()
    ->getRepository('PondGeolocBundle:User_Lake');
