Question

如何开始使用Doctrine 2 + ZF？任何教程或资源？

在附注中，我听说ZF2将使用Doctrine作为其模型，是吗？

Answer 1

使用ZF和Doctrine 2的好处是，要集成它们几乎没有什么需要做的。基本上，您只需要访问在应用程序引导期间设置的Doctrine 2 EntityManager实例，并确保在index.php中加载Doctrine命名空间（您需要使用） Doctrine的ClassLoader，Zend_Loader还不支持名称空间。）

您可以通过Resource Plugin在引导程序中手动实例化EntityManager，或者更容易实例化（这使得在application.ini中存储数据库配置变得容易）。你几乎可以按照Doctrine手册中configuring and obtaining an Entity Manager的文档进行操作，只需让你的bootstrap资源中的init()方法返回实例。

您可能希望高度依赖依赖注入来将EM传递给需要它的各种对象。有关将引导程序资源传递到操作控制器的简便方法，请参阅creating a simple resource injector上的这篇文章。

我一直在使用带有ZF的Doctrine 2，因为它已经使用了alpha版本，并且发现它非常令人愉快。

Answer 2

我可以从我使用的bootstrap.php中给你一些例子：

    public function _initDoctrine() {
                if(PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION >= 3) {
                    require_once('bootstrapDoctrine.inc.php');

                    //things below this line are for convenience        
                    require_once(dirname(__FILE__).'/../library/doctrinehelpers/requireEntitiesOnce.php');
                    Zend_Registry::set('doctrineEm', $em);
                    return $em;
                }
        }

在boostrapDoctrine.inc.php中我有这个：

use Doctrine\Common\ClassLoader,
    Doctrine\ORM\Configuration,
    Doctrine\ORM\EntityManager,
    Doctrine\Common\Cache\ArrayCache,
    Doctrine\DBAL\Logging\EchoSQLLogger;

    require_once(realpath(APPLICATION_PATH . '/../library').'/doctrine2/lib/Doctrine/Common/ClassLoader.php');

    $doctrineClassLoader = new ClassLoader('Doctrine', realpath(APPLICATION_PATH . '/../library').'/doctrine2/lib');
    $doctrineClassLoader->register();


    //no way to have your proxies generated in different directory per ZF module it seems so we use a global one
    $proxiesClassLoader = new ClassLoader('Proxies', realpath(APPLICATION_PATH . '/models/doctrineproxies'));
    $proxiesClassLoader->register();

    /*
     * @TODO make this step iterate over available modules
     */
        $driverImpl = $config->newDefaultAnnotationDriver(array(APPLICATION_PATH . '/modules/mymodule1/models/doctrineentities',APPLICATION_PATH . '/modules/mymodule2/models/doctrineentities'));
    $config->setMetadataDriverImpl($driverImpl);
    $config->setMetadataCacheImpl($cache);
    $config->setQueryCacheImpl($cache);

    // Proxy configuration
    $config->setProxyDir(realpath(APPLICATION_PATH . '/models/doctrineproxies'));
    $config->setProxyNamespace('Proxies');


    /**
     * this SQL logger is golden
         * @TODO implement a switch for verbose debugging
     */ 

     //   $logger = new Doctrine\DBAL\Logging\DebugStack();
     //   $config->setSQLLogger($logger);
     //   register_shutdown_function(function($logger) {
     //       echo '<pre>';
     //       print_r($logger->queries);
     //   }, $logger);


    $config->setAutoGenerateProxyClasses( true ); //disable in production environment

    $doctrineConfig = $this->getOption('resources'); //from ini
    $dbparams = $doctrineConfig['db']['params'];
    $connectionOptions = array(
         'driver'    => $doctrineConfig['db']['adapter'],
         'user'      => $dbparams['username'],
         'password'  => $dbparams['password'],
         'dbname'    => $dbparams['dbname'],
         'host'      => $dbparams['host']
    );
    $em = EntityManager::create($connectionOptions, $config); //stored in zend registry later

要允许doctrine命令行工具运行，我必须创建一个库/ doctrine2 / lib / cli-config.php，它也是一个精简的zend框架引导程序。这个配置的缺点是我必须从这个目录中调用doctrine cli。适合我;）

/*
* @TODO make the cli-tool more flexible by better path detection
*/
// Define path to application directory
defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../../../application'));

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));

// Ensure library/ is on include_path
set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH . '/../library'),
    realpath(APPLICATION_PATH . '/../../include'),
    get_include_path(),
)));

/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);


$    application->getBootstrap()->bootstrap('doctrine');
$em = $application->getBootstrap()->getResource('doctrine');

/*
$configuration = new \Doctrine\Common\Cli\Configuration();
$configuration->setAttribute('em', $em);
*/

$helperSet = new \Symfony\Components\Console\Helper\HelperSet(array(
    'db' => new \Doctrine\DBAL\Tools\Console\Helper\ConnectionHelper($em->getConnection()),
    'em' => new \Doctrine\ORM\Tools\Console\Helper\EntityManagerHelper($em)
));

现在我们都希望有一个更好的学说整合，但这只会发生在ZF 2中，朝着像学说这样的命名空间迈出了一大步。

希望我能提供帮助。
