Posted 2021-05-15

function _initDoctrine() {
	// setup Zend & Doctrine Autoloaders
	require_once "Doctrine/Common/ClassLoader.php";

	$zendAutoloader = Zend_Loader_Autoloader::getInstance();

	// $autoloader = array(new \Doctrine\Common\ClassLoader(), 'loadClass');

	$autoloader = array(new \Doctrine\Common\ClassLoader('Symfony'), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'Symfony\\');
	$autoloader = array(new \Doctrine\Common\ClassLoader('Doctrine'), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'Doctrine\\');
	$autoloader = array(new \Doctrine\Common\ClassLoader('DoctrineExtensions'), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'DoctrineExtensions\\');
	$autoloader = array(new \Doctrine\Common\ClassLoader('Application\\Models', realpath(__DIR__ . '/..')), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'Application\\Models\\');
	$autoloader = array(new \Doctrine\Common\ClassLoader('Application\\Proxies', realpath(__DIR__ . '/..')), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'Application\\Proxies');
	$autoloader = array(new \Doctrine\Common\ClassLoader('DoctrineExtensions'), 'loadClass');
	$zendAutoloader->pushAutoloader($autoloader, 'DoctrineExtensions\\');

	// setup configuration as seen from the sandbox application
	// TODO: read configuration from application.ini
	$config = new \Doctrine\ORM\Configuration;
	$cache = new \Doctrine\Common\Cache\ArrayCache;
	$config->setMetadataCacheImpl($cache);
	$driverImpl = $config->newDefaultAnnotationDriver(realpath(__DIR__ . '/models'));
	$config->setMetadataDriverImpl($driverImpl);
	$config->setQueryCacheImpl($cache);
	$config->setProxyDir(realpath(__DIR__ . '/proxies'));
	$config->setProxyNamespace('Application\\Proxies');
	$config->setAutoGenerateProxyClasses(true);

	$connectionOptions = array(
	  'driver' => 'pdo_mysql',
	  'user' => 'root',
	  'password' => '',
	  'dbname' => 'learningzf'
	);

	// setup entity manager
	$em = \Doctrine\ORM\EntityManager::create($connectionOptions, $config);
	Zend_Registry::set("em", $em);
	return $em;
