Question

使用CodeIgniter工作几个月，newbe与Doctrine一起工作。我最近使用https://github.com/wildlyinaccurate/CodeIgniter-2-with-Doctrine-2作为基础，并使用generate_classes()函数（ application / libraries / Doctrine.php）在mysql表/列中定义实体，在构造函数结束前调用一次，在创建实体后对其进行注释）：

应用/库/ Doctrine.php

    Doctrine\Common\Cache\ArrayCache,
    Doctrine\DBAL\Logging\EchoSQLLogger,
    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,

    $doctrineClassLoader = new ClassLoader('Doctrine', APPPATH . 'libraries');
    $doctrineClassLoader->register();
    $entitiesClassLoader = new ClassLoader('models', rtrim(APPPATH, "/"));
    $entitiesClassLoader->register();

      'dbname' => $db['default']['database']

    // Create EntityManager
    $this->em = EntityManager::create($connectionOptions, $config);

    /* Generate entity objects automatically from mysql db tables. Run once.

     */
    //$this->generate_classes();
  }

  /**

   * @return none
   */
  function generate_classes()
  {
    $this->em->getConfiguration()->setMetadataDriverImpl(new DatabaseDriver($this->em->getConnection()->getSchemaManager()));

    $cmf = new DisconnectedClassMetadataFactory();
    $cmf->setEntityManager($this->em);
    $metadata  = $cmf->getAllMetadata();
    $generator = new EntityGenerator();

    $generator->setUpdateEntityIfExists(true);
    $generator->setGenerateStubMethods(true);
    $generator->setGenerateAnnotations(true);

  }

已编辑：如何将CRUD operations用于相关表格？我知道，阅读用户指南，但（例如）如果$post = $entityManager->find("Customers", $idCustomer);是单行，哪个函数/语法返回所有行（和相关的）？

Answer 1

以下代码应该为您提供表中的所有行。

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