Doctrine 2和codeigniter 2,如何使用生成的代码

标签: php codeigniter doctrine

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

<?php
use Doctrine\Common\ClassLoader,
    Doctrine\ORM\Configuration,
    Doctrine\ORM\EntityManager,
    Doctrine\Common\Cache\ArrayCache,
    Doctrine\DBAL\Logging\EchoSQLLogger,
    Doctrine\ORM\Mapping\Driver\DatabaseDriver,
    Doctrine\ORM\Tools\DisconnectedClassMetadataFactory,
    Doctrine\ORM\Tools\EntityGenerator;

 */
class Doctrine
{
  /**
   * @var EntityManager $em
   */
  public $em = null;

  /**
   * constructor
   */
  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.
    require_once APPPATH . 'libraries/Doctrine/Common/ClassLoader.php';

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

    // Set up caches
    $config = new Configuration;
    $cache  = new ArrayCache;
    $config->setMetadataCacheImpl($cache);
    $driverImpl = $config->newDefaultAnnotationDriver(array(
      APPPATH . 'models/Entities'
    ));
    $config->setMetadataDriverImpl($driverImpl);
    $config->setQueryCacheImpl($cache);

    // Proxy configuration
    $config->setProxyDir(APPPATH . 'models/proxies');
    $config->setProxyNamespace('Proxies');

    // Set up logger
    //$logger = new EchoSQLLogger;
    //$config->setSQLLogger($logger);

    $config->setAutoGenerateProxyClasses(TRUE);
    // Database connection information
    $connectionOptions = array(
      'driver' => 'pdo_mysql',
      'user' => $db['default']['username'],
      'password' => $db['default']['password'],
      'host' => $db['default']['hostname'],
      'dbname' => $db['default']['database']
    );

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

    /* Generate entity objects automatically from mysql db tables. Run once.
     * http://codesamplez.com/development/using-doctrine-with-codeigniter
     */
    //$this->generate_classes();
  }

  /**
   * generate entity objects automatically from mysql db tables
   * @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);
    $generator->generate($metadata, APPPATH . "models/Entities");

  }

}

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)?

1 个答案:

答案 0 :(得分:1)

以下代码应该为您提供表中的所有行。

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