use*_*960 4 php mysql doctrine symfony doctrine-orm
我正在尝试使用symfony/doctrine创建一个小应用程序来读取表中的记录.我的步骤:
3)创建了GS\OrderBundle\Entity\CustomerRepository.php(我不知道为什么我还需要它,它是自动生成的).源代码:
namespace GS\OrderBundle\Entity;
use Doctrine\ORM\EntityRepository;
class CustomerRepository extends EntityRepository
{
}
4)修改了CustomerController.php:
<?php
namespace GS\OrderBundle\Controller;
use Symfony\Component\HttpFoundation\Response;
use GS\OrderBundle\Entity\Customer;
use Doctrine\ORM\EntityManager;
class CustomerController
{
public function indexAction($id)
{
$customer = $this->getDoctrine()->getRepository('GSOrderBundle:Customer')->find($id);
return new Response(
'<html><body>Number: '.$id.'</body></html>'
);
}
}
并得到以下错误:
尝试在类"GS\OrderBundle\Controller\CustomerController"上调用方法"getDoctrine".

您需要扩展Symfony的Controller类才能使用getDoctrine()方法.
所以:
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class CustomerController extends Controller
{
public function indexAction($id)
{
$customer = $this->getDoctrine()->getRepository('GSOrderBundle:Customer')->find($id);
return new Response(
'<html><body>Number: '.$id.'</body></html>'
);
}
}
(您也可以将控制器定义为服务,但这是更复杂的解决方案)
