get doctrine db config in zf2 - doctrine-orm

Question

I want to use doctrine db config to access to DBAL layer in doctrine, I have the following configuration in my doctrine db file config:
database.local.php
return array(
'doctrine' => array(
'connection' => array(
'orm_default' => array(
'driverClass' => 'Doctrine\DBAL\Driver\PDOPgSql\Driver',
'params' => array(
'host' => 'localhost',
'port' => '5432',
'user' => 'postgres',
'password' => '123456',
'dbname' => 'test'
)
)
)
)
);
and in my controller
IndexController.php
use Doctrine\DBAL\DriverManager;
public function testAction(){
$conn = DriverManager::getConnection($params, $config);
}
I want to use db config above in the getConnection function, is this possible?

Answer 1

If you've a db configuration in your local.php, so why don't you access it through the EntityManager ? Just like this :
public function testAction(){
$em = ->getServiceLocator()
->get('Doctrine\ORM\EntityManager');
$conn = $em->getConnection();
}
If you want to get it through the DriverManager :
$config = new \Doctrine\DBAL\Configuration();
$connectionParams = array(
'host' => 'localhost',
'port' => '5432',
'user' => 'postgres',
'password' => '123456',
'dbname' => 'test'
'driver' => 'pdo_pgsql',
);
$conn = DriverManager::getConnection($connectionParams, $config);
EDIT :
You can also get directly an instance of Doctrine\DBAL\Connection using the Registered Service names provided by Doctrine with your actual db configuration :
$conn = $this->getServiceLocator()->get('doctrine.connection.orm_default');
As the DriverManager::getConnection() method, this will return a Doctrine\DBAL\Connection which wraps the underlying driver connection.

Sure.
First of all you should use ServiceLocator
ServiceLocator are auto injected into classes that implements \Zend\ServiceManager\ServiceLocatorAwareInterface
AbstractActionController, of your zf2 controllers already implements this interface.
To use into a class (model by example) you should declare implements and two methods that are designed by interface, setServiceLocator and getServiceLocator.
<?php
namespace Security\Repository;
use Zend\ServiceManager\ServiceLocatorInterface;
use Zend\ServiceManager\ServiceLocatorAwareInterface;
class Repository implements ServiceLocatorAwareInterface
{
protected $serviceLocator;
public function setServiceLocator(ServiceLocatorInterface $serviceLocator)
{
$this->serviceLocator = $serviceLocator;
}
public function getServiceLocator()
{
return $this->serviceLocator;
}
}
Using ServiceLocator are easy to do anything on ZF2. Try To understand how it works to get the fully power of zf2.
$configArray = $this->getServiceLocator()->get('config');
$config = new \Doctrine\DBAL\Configuration();
$connectionParams = $configArray['doctrine']['connection']['orm_default']['params']
$conn = DriverManager::getConnection($connectionParams, $config);
