Symfony2 Use Doctrine in Service Container - doctrine

Question

How do I use Doctrine in a service container?
The Code just causes an error message "Fatal error: Call to undefined method ...::get()".
<?php
namespace ...\Service;
use Doctrine\ORM\EntityManager;
use ...\Entity\Header;
class dsdsf
{
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
public function create()
{
$id = 10;
$em = $this->get('doctrine')->getEntityManager();
$em->getRepository('...')->find($id);
}
}
services.yml
service:
site:
class: ...\Service\Site

Answer 1

According to your code, you already have an EntityManager injected. You don't need to call $em = $this->get('doctrine')->getEntityManager() — just use $this->em.
If you don't inject an EntityManager already, read this.
UPDATE:
You need to make the container inject an EntityManager into your service. Here's an example of doing it in config.yml:
services:
your.service:
class: YourVendor\YourBundle\Service\YourService
arguments: [ #doctrine.orm.entity_manager ]
I prefer to define bundles' services in their own services.yml files, but that's a bit more advanced, so using config.yml is good enough to get started.

Answer 2

For easily accessing the Entitymanager use the following one:
//services.yml
your service here:
class: yourclasshere
arguments: [#doctrine.orm.entity_manager]
And in the class itself:
class foo
{
protected $em;
public function __construct(\Doctrine\ORM\EntityManager $em)
{
$this->em = $em;
}
public function bar()
{
//Do the Database stuff
$query = $this->em->createQueryBuilder();
//Your Query goes here
$result = $query->getResult();
}
}
This is my first answer so any comments are appreciated :)

Answer 3

Please try this code:
$em=$this->container->get('doctrine')->getEntityManager();
$rolescheduels=$em->getRepository('OCSOCSBundle:RoleScheduel')->findByUser($user->getId());

Answer 4

For Symfony 3.x
The most easy-peasy solution for me was to just turn on autowiring/autoconfiguring, and then injecting the service I needed via the constructor. Note that I have also allowed any controller to be injected as a service by setting resource: '../../src/AppBundle/*'
#services.yml or config.yml
services:
_defaults:
autowire: true
autoconfigure: true
public: false
# Allow any controller to be used as a service
AppBundle\:
resource: '../../src/AppBundle/*'
# you can exclude directories or files
# but if a service is unused, it's removed anyway
exclude: '../../src/AppBundle/{Entity,Repository,Tests,DataFixtures,Form}'
Then in any service, you can inject & use the entity manager $em (or any other service/controller) via the constructor like this:
// class xyz
private $em;
// constructor
public function __construct(\Doctrine\ORM\EntityManager $em) {
$this->em = $em;
}
public function bar() {
//Do the Database stuff
$query = $this->em->createQueryBuilder();
//Your Query goes here
$result = $query->getResult();
}

for anyone who works with symfony3: u need to do the following inside config/services.yml in order to use doctrine in Service Container:
servicename_manager:
class: AppBundle\Services\MyServiceClass
arguments: [ "#doctrine.orm.entity_manager" ]

Answer 6

in the Symfony 3.4. If you want to use Doctrine in a service you can do it:
Only this method worked for me
services.yml:
YourBundle\PatchService\YourService:
public: true
arguments: [ '#doctrine.orm.entity_manager' ]
Service:
class YourService
{
private $em;
public function __construct($em) {
$this->em = $em;
}
Controller:
use YourBundle\PatchService\YourService;
/**
* #Route("/YourController/",name="YourController")
*/
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$Notification = new YourService($em);

Answer 7

I am using Symfony 3.4. If you want to create a service in a bundle this works for me:
services:
Vendor\YourBundle\Service\YourService:
arguments:
$em: '#doctrine.orm.entity_manager'
In your Service.php
<?php
namespace Hannoma\ElternsprechtagBundle\Service;
use Doctrine\ORM\EntityManager;
use Hannoma\ElternsprechtagBundle\Entity\Time;
class TimeManager
{
protected $em;
public function __construct(EntityManager $em)
{
$this->em = $em;
}
}

Since 2017 and Symfony 3.3 you can register Repository as service, with all its advantages it has.
Your code would change like this.
1. Service configuration
# app/config/services.yml
services:
_defaults:
autowire: true
...\Service\:
resource: ...\Service
2. Create new class - custom repository:
use Doctrine\ORM\EntityManagerInterface;
class YourRepository
{
private $repository;
public function __construct(EntityManagerInterface $entityManager)
{
$this->repository = $entityManager->getRepository(YourEntity::class);
}
public function find($id)
{
return $this->repository->find($id);
}
}
3. Use in any Controller or Service like this
class dsdsf
{
private $yourRepository;
public function __construct(YourRepository $yourRepository)
{
$this->yourRepository = $yourRepository;
}
public function create()
{
$id = 10;
$this->yourRepository->find($id);
}
}
