在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的方法时，我遇到以下致命错误

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 楷模   映射   库   实体   代理

我的doctrine.php有像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。

3 个答案:

答案 0 :(得分：6)

您已将Doctrine \ ORM \ Mapping导入为ORM。

因此，您应该在Comment class annotation中使用@ORM\Entity而不是@Entity。

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

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

答案 1 :(得分：0)

你写了

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

@Entity与该注释的参数之间有一个空格：删除它。

答案 2 :(得分：0)

尽管OP在评论中发布了答案。

当我试图调用任何doctrine的clear-cache命令时，它引发了异常。

$ vendor/bin/doctrine orm:clear-cache:metadata Cannot clear APC Cache from Console, its shared in the Webserver memory and not accessible from the CLI.。

我的开发环境不使用APC，因此存储库运行正常。当我将其上传到生产服务器时，它失败并出现与OP相同的错误。

我可以通过从网页执行apc_clear_cache()来解决此问题。之后自定义存储库加载正常。

EG： http://mydoamin.com/clear-cache.php 

<?php

apc_clear_cache();

在CLI中运行它只会清除CLI缓存而不是Web服务器的缓存。 http://php.net/manual/en/function.apc-clear-cache.php
