Symfony2 access Doctrine Entity Manager in custom class - symfony

Question

UPDATE:
In case you need to work with Entity Manager in a custom class, you could go this way:
put this code in your bundle:
use Symfony\Component\DependencyInjection\Container;
use Symfony\Component\HttpFoundation\Request;
require_once DIR . '/../../../app/bootstrap.php.cache';
require_once DIR . '/../../../app/AppKernel.php';
class ApplicationBoot {
private static $kernel;
public static function getContainer() {
if(self::$kernel instanceof \AppKernel) {
if(!self::$kernel->getContainer() instanceof Container){
self::$kernel->boot();
}
return self::$kernel->getContainer();
}
$environment = 'prod';
if (!array_key_exists('REMOTE_ADDR', $_SERVER) || in_array(#$_SERVER['REMOTE_ADDR'], array('127.0.0.1', '::1', 'localhost'))) {
$environment = 'dev';
}
self::$kernel = new \AppKernel($environment, false);
self::$kernel->boot();
return self::$kernel->getContainer();
}
public static function shutDown() {
self::$kernel->shutdown();
}}
So now you can access EntityManager:
$container = ApplicationBoot::getContainer();
$entityManager = $container->get('doctrine')->getEntityManager();

Answer 1

I have not seen a service file like this:
arguments:
entityManager: "#doctrine.orm.entity_manager"
Probably should be:
arguments: [#doctrine.orm.entity_manager]
UPDATE:
Based on some comments it appears that you are trying to do:
$job = new PostJob();
And expecting that entity manager will somehow be passed. And that is just not the way things work. You need to do:
$job = $this->get('postjob.service.id');
In order to have the Symfony 2 dependency injection work. Review the chapter in the manual on services. It might seem a bit over whelming at first but once you get a few services working then it becomes second nature.

To load the services.yml from your bundle, you need to provide an extension class:
// src/Vendor/YourBundle/DedendencyInjection/VendorYourBundleExtension.php
namespace Vendor\YourBundle\DependencyInjection;
use Symfony\Component\HttpKernel\DependencyInjection\Extension,
Symfony\Component\DependencyInjection\ContainerBuilder,
Symfony\Component\DependencyInjection\Loader\YamlFileLoader,
Symfony\Component\Config\FileLocator;
class VendorYourBundleExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$loader = new YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
$loader->load('services.yml');
}
}
