symfony2中的自定义存储库类 [英] custom repository class in symfony2

问题描述

我是symfony2的新手，通过命令行创建实体类时创建了一个存储库类，但无法访问该存储库类中的自定义函数.如何在symfony2中创建自定义存储库类?有人可以从头开始为我提供一些示例代码的逐步说明吗?

I'm new in symfony2.I created a repository class when I created an entity class through command line.But I couldn't access my custom functions in that repository class. how to create custom repository class in symfony2? Can anybody give me a step by step explanation from scratch with some sample code?

下面是我的存储库类

namespace Mypro\symBundle\Entity;

use Doctrine\ORM\EntityRepository;

/**
 * RegisterRepository
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class RegisterRepository extends EntityRepository
{


    public function findAllOrderedByName()
    {
        return $this->getEntityManager()
            ->createQuery('SELECT p FROM symBundle:Register p ORDER BY p.name ASC')
            ->getResult();
    }


}

我以这种方式在控制器中打电话

I called in my controller like this way

$em = $this->getDoctrine()->getEntityManager();
          $pro = $em->getRepository('symBundle:Register')
            ->findAllOrderedByName();

我遇到了以下错误

Undefined method 'findAllOrderedByName'. The method name must start with either findBy or findOneBy!

我的代码中是否有任何错误?创建存储库类时有任何错误?我需要使用任何课程吗?

Do I have any mistake in my code ? Any mistake in creating repository class? did i need to use any class.

推荐答案

我认为您只是忘记了在您的实体中注册此存储库. 您只需在实体配置文件中添加存储库类.

I think you just forgot to register this repository in your entity. You just have to add in your entity configuration file the repository class.

在src/Mypro/symBundle/Resources/config/doctrine/Register.orm.yml中:

In src/Mypro/symBundle/Resources/config/doctrine/Register.orm.yml:

Mypro\symBundle\Entity\Register:
    type: entity
    repositoryClass: Mypro\symBundle\Entity\RegisterRepository

为了以防万一，别忘了在此更改后清除缓存.

Don't forget to clear your cache after this change, just in case.

如果您使用的是Annotations(而不是yml config)，请添加以下内容:

And if you're using Annotations (instead of yml config) then instead of the above, add something like:

/**
 * @ORM\Entity(repositoryClass="Mypro\symBundle\Entity\RegisterRepository")
*/

进入您的Entity类以注册存储库

to your Entity class to register the repository
