Doctrine:自定义实体存储库

Question

构建自定义实体存储库时遇到一些问题.

尝试自定义实体存储库时,我有以下致命错误

Fatal error: Uncaught exception 'BadMethodCallException' with message 'Undefined method 'getByParentId'. The method name must start with either findBy or findOneBy!' in C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\ORM\EntityRepository.php:215 Stack trace: #0 C:\Users\user\Desktop\projects\interview\application\controllers\CommentController.php(58): Doctrine\ORM\EntityRepository->__call('getByParentId', Array) #1 C:\Users\user\Desktop\projects\interview\application\controllers\CommentController.php(58): Doctrine\ORM\EntityRepository->getByParentId('1') #2 [internal function]: CommentController->viewCommentsListByParentId('1') #3 C:\Users\user\Desktop\projects\interview\system\core\CodeIgniter.php(359): call_user_func_array(Array, Array) #4 C:\Users\user\Desktop\projects\interview\index.php(203): require_once('C:\Users\user\D...') #5 {main} thrown in C:\Users\user\Desktop\projects\interview\application\libraries\Doctrine\ORM\EntityRepository.php on line 215

我的项目结构是Mappings Repositories Entities Proxies模型

我的doctrine.php有这样的存储库加载器

// load the repositories
$repositoryClassLoader = new \Doctrine\Common\ClassLoader('Repositories', APPPATH.'models');
$repositoryClassLoader->register();

我的模型类有以下声明

namespace Entities;

use Doctrine\ORM\Mapping as ORM;

/**
 * Entities\Comment
 * @Entity (repositoryClass="Repositories\CommentRepository")
 */
class Comment
{

My Repository类具有以下声明

namespace Repositories;
use Doctrine\ORM\EntityRepository;
use Entities;

class CommentRepository extends EntityRepository {
    public function getByParentId($parentid) {
        return parent::findBy(array('parentid' => $parentid), array('creationdate' => 'DESC'));
    }
}

控制器代码调用自定义存储库的方法

   public function viewCommentsListByParentId($parentid) {
        $data = array();
        $data ['comment'] = $this->em->getRepository('Entities\Comment')->getByParentId($parentid);

        $this->load->view('commentsList', $data);
    } 

我做错了什么??? 请帮忙.

Answer 1

您已将Doctrine\ORM\Mapping导入为ORM.

因此,您应该使用@ORM\Entity而不是@Entity在Comment类注释中.

因为现在它不加载注释 ["customRepositoryClassName"]=> NULL

 /**
  * Entities\Comment
  * @ORM\Entity (repositoryClass="Repositories\CommentRepository")
  */
 class Comment
 {
