Creating a symfony service that can access doctrine - php

Question

I have a signupAction inside a controller. I would like this signupAction to call another service which then will create an account. So I created a service called AccountService which extends Controller as I would like to get access to doctrine ($this->getDoctrine()...) in order to save an account to the database. However when i cann my service, it tells me it has no access to the container (null).
if (!$this->container->has('doctrine')) {
The above line fails as container is null.
This is how I call the service:
$accountService = $this->get('app.account');
$accountService->createAccount($account);
And i configured it in services.yml as:
services:
app.account:
class: AppBundle\Service\AccountService
Can anyone help me figure out how to get this working? Or as a better ideas how to have services called to deal with database instead of it all in my actions in controllers?
I have symfony 3.2

I believe that most people starting from scratch would use ORM, I didn't because I had existing PHP code working with PDO SQL. Here is an example showing how to access Doctrine DB connection:
In [YourBundle]\Resources\config\services.yml
services:
#dependency injection services
pdo_connection:
class: [YourBundle]\DependencyInjection\PDOManagement\PdoConnection
arguments: ["#doctrine.dbal.default_connection"]
Then in [YourBundle]\DependencyInjection\PDOManagement\PdoConnection.php
<?php
namespace [YourBundle]\DependencyInjection\PDOManagement;
use Doctrine\DBAL;
class PdoConnection {
protected $db;
public function __construct($dbalConnection){
$this->db = $dbalConnection;
}
}
?>
this->db of class PdoConnection will have access to the DB connection after constructor.
I let you figure out how to use it according to your need.
