Doctrine 2和codeigniter 2，如何使用生成的代碼

Question

使用CodeIgniter工作幾個月，newbe with Doctrine。 我https://github.com/wildlyinaccurate/CodeIgniter-2-with-Doctrine-2最近的工作爲基礎，定義與generate_classes()功能（應用程序/庫/ Doctrine.php，調用一次構造函數結束之前，創建實體後發表評論吧）從MySQL表/實體列：

應用/libraries/Doctrine.php

    Doctrine\ORM\Mapping\Driver\DatabaseDriver, 
    Doctrine\ORM\Tools\DisconnectedClassMetadataFactory, 
    Doctrine\ORM\Tools\EntityGenerator;

    public $em = null; 

    /**

    public function __construct() 
    { 
    // load database configuration from CodeIgniter 
    require APPPATH . 'config/database.php'; 

    // Set up class loading. You could use different autoloaders, provided by your favorite framework, 
    // if you want to.

    } 

    /**

    $cmf = new DisconnectedClassMetadataFactory();

編輯：我如何使用它CRUD operations與相關表？我知道，閱讀用戶指南，但（例如）如果$post = $entityManager->find("Customers", $idCustomer);是單行，哪個函數/語法返回所有行（和相關）？

Answer 1

下面的代碼應該會給你表中的所有行。

$em->getRepository('Customers')->findAll();
