Doctrine 2, creating EntityManager from PDO - error - php

Question

I have the following scenario:
class ModelManager extends EntityManager implements ModelManagerInterface
{
public function __construct($conn, $options = array())
{
$isDev = empty($options['is_dev']) ? false : $options['is_dev'];
// #see Doctrine\ORM\EntityManager#create()
$config = ArrayUtils::arrayMergeRecursiveRight($options, array(
'cache' => $isDev ? new Cache\ArrayCache : new Cache\ApcCache,
'queryCache' => $isDev ? new Cache\ArrayCache : new Cache\ApcCache,
'modelsProxiesPath' => getcwd() . '/cache/ModelProxies',
));
// create Configuration object
if (is_array($options)) {
$config = $this->initConfig($options);
if (!$config->getMetadataDriverImpl()) {
throw ORMException::missingMappingDriverImpl();
}
}
// test EventManager object
$eventManager = empty($options['eventManager']) ? new EventManager() : $options['eventManager'];
switch (true) {
case ($conn instanceof \PDO):
$conn = array(
'driver' => 'pdo_' . $conn->getAttribute(\PDO::ATTR_DRIVER_NAME),
'pdo' => $conn,
);
print_r($conn);
$conn = \Doctrine\DBAL\DriverManager::getConnection($conn, $config, $eventManager);
break;
case (is_string($conn)):
$pdo = new \PDO($conn);
if ('oci8' !== $pdo->getAttribute(\PDO::ATTR_DRIVER_NAME)) {
$conn = array(
'driver' => 'pdo_' . $pdo->getAttribute(\PDO::ATTR_DRIVER_NAME),
'pdo' => $pdo,
);
} else {
$conn = $this->mapDsnToDoctrine($conn);
}
$conn = \Doctrine\DBAL\DriverManager::getConnection($conn, $config, $eventManager);
break;
case (is_array($conn)):
$conn = \Doctrine\DBAL\DriverManager::getConnection($conn, $config, $eventManager);
break;
case ($conn instanceof Connection):
if ($eventManager !== null && $conn->getEventManager() !== null) {
throw ORMException::mismatchedEventManager();
}
break;
default:
throw new Exception\InvalidArgument("Invalid argument: " . json_encode($conn));
}
// parent constructor
// #see Doctrine\ORM\EntityManager#__construct()
parent::__construct($conn, $config, $conn->getEventManager());
}
// ...
}
This is used smth like this:
self::$em = new ModelManager(
new \PDO(self::$config['db_adapter']['connection']['dsn']),
empty(self::$config['db_adapter']['options']['doctrine']) ?
array() : self::$config['db_adapter']['options']['doctrine']
);
$tool = new \Doctrine\ORM\Tools\SchemaTool(self::$em);
$classes = $this->db(self::$config['db_adapter']['options']['doctrine']['modelsPath']);
$tool->updateSchema($classes);
Where the config looks like this:
$config = array(
'db_adapter' => array(
'connection' => array(
'dsn' => 'mysql://root:******#localhost/netistest' . time(),
),
'options' => array(
'doctrine' => array(
'cache' => 'ArrayCache|ApcCache', // development|testing&production
'queryCache' => 'ArrayCache|ApcCache', // development|testing&production
'modelsPath' => __DIR__ . '/NetisTest/Model',
'modelsProxiesPath' => __DIR__ . '/cache/doctrine/ModelProxies',
'modelsProxiesNamespace' => 'App\Models\Proxies',
'modelsProxiesAutogenerate' => 'App\Models\Proxies',
),
'zend' => array(
// at this moment we decided not to implement Zend\DbAdapter
),
)
),
);
The problem with all this strange configuration, is that, after instantiating the ModelManager class, when trying to interrogate the database for creating the tables associated to my models, it throws the following error:
Doctrine\DBAL\DBALException: An exception occurred while executing 'SHOW FULL TABLES WHERE Table_type = 'BASE TABLE'':
SQLSTATE[3D000]: Invalid catalog name: 1046 No database selected

You can find the code (however in an older form) here as well:
https://github.com/athemcms/Component_NetisDb/blob/master/library/Netis/Db/ModelManager/ModelManager.php
Can anyone please help me in understanding why PDO isn't enough for EntityManager to remember the database as well ?
Thanks a lot in advance!
