【问题描述】：

我正在 symfony 中为应用程序中的视频功能编写数据夹具，以插入一些测试数据（视频上的 cmets） 这是代码。它是将数据添加到测试数据库的夹具类：

<?php
namespace XOZ\AppBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
use XOZ\AppBundle\DataFixtures\OrderHelper;
use XOZ\AppBundle\Entity\Comment;

class CreateVideoCommentTestData extends AbstractFixture implements OrderedFixtureInterface, ContainerAwareInterface

    use VideoListDataTrait;

    /**
     * @var ContainerInterface
     */
    private $container;
    private $comment_service;

    public function getOrder()
    
        return OrderHelper::create()->requiresUser()->requiresVideoShoutOut()->get();
    

    public function setContainer(ContainerInterface $container = null)
    
        $this->container = $container;
        $this->comment_service = $this->container->get('xoz_app.comment_service');
    

    public function load(ObjectManager $manager)
    
        $videos = $this->getVideoList();

        foreach ($videos as $name => $key) 
            $song = $this->getReference($name);

            $message = 'I am a video comment';

            // comment on all songs
            $this->comment_service->addVideoShoutOutComment($this->getReference('Deletable'), $song, $message, true);
            $this->comment_service->addVideoShoutOutComment($this->getReference('AutoMute'), $song, $message, true);
            $this->comment_service->addVideoShoutOutComment($this->getReference('AutoMuteExempt'), $song, $message, true);
            $this->comment_service->addVideoShoutOutComment($this->getReference('Blocked'), $song, $message, true);

            // comment on these songs
            if ($name === 'My Metal Song') 
                $this->comment_service->addVideoShoutOutComment($this->getReference('User2'), $song, $message, true);
            

            // comment on User1's songs
            if( $key === 'User1' ) 
                $this->comment_service->addVideoShoutOutComment($this->getReference('User1'), $song, $message, true);
                $this->comment_service->addVideoShoutOutComment($this->getReference('User2'), $song, $message, true);
            

            // comment on User2's songs
            if( $key === 'User2' ) 
                $this->comment_service->addVideoShoutOutComment($this->getReference('Superuser'), $song, $message, true);
                $this->comment_service->addVideoShoutOutComment($this->getReference('User1'), $song, $message, true);
                $this->comment_service->addVideoShoutOutComment($this->getReference('User1'), $song, $message, true);
            

            // comment on BlockedUser's songs
            if( $key === 'Blocked' ) 
                $this->comment_service->addVideoShoutOutComment($this->getReference('User1'), $song, $message, true);
                $this->comment_service->addVideoShoutOutComment($this->getReference('User1'), $song, $message, true);
            
        
    

这是我正在使用的特征：

<?php

namespace XOZ\AppBundle\DataFixtures\ORM;

trait VideoListDataTrait

    public function getVideoList()
    
        return [
            'My Metal VideoShoutOut'         => 'Superuser',
            'My Rock VideoShoutOut'          => 'Superuser',
            'My Blackmetal VideoShoutOut'    => 'Superuser',
            'My Trashmetal VideoShoutOut'    => 'Superuser',
            'My Coremetal VideoShoutOut'     => 'Superuser',
            'My HipHop VideoShoutOut'        => 'User1',
            'My DrumAndBass VideoShoutOut'   => 'User2',
            'Blocked User VideoShoutOut'     => 'Blocked',
            'AutoMute User VideoShoutOut'    => 'AutoMute',
            'AutoMuteExempt User VideoShoutOut'    => 'AutoMuteExempt',
            'CrewSuperAdminVideoShoutOut1'   => 'CrewSuperAdmin',
            'CrewSuperAdminVideoShoutOut2'   => 'CrewSuperAdmin',
            'CrewSuperAdminVideoShoutOut3'   => 'CrewSuperAdmin',
            'CrewSuperAdminVideoShoutOut4'   => 'CrewSuperAdmin',
            'CrewSuperAdminVideoShoutOut5'   => 'CrewSuperAdmin',
            'CrewAdminVideoShoutOut1'        => 'CrewAdmin',
            'CrewUserVideoShoutOut1'         => 'CrewUser',
            'CrewUserVideoShoutOut2'         => 'CrewUser',
            'CrewNonMemberVideoShoutOut1'    => 'CrewNonMember1',
            'CrewBlockedVideoShoutOut1'      => 'CrewBlocked1',
            'CrewBlockedVideoShoutOut2'      => 'CrewBlocked2',
        ];
    

但是在加载数据夹具时，我得到了这个错误：

[OutOfBoundsException]                                 
  Reference to: (My Metal VideoShoutOut) does not exist

我在这里做错了什么？

【参考方案1】：

你在哪里调用函数 $this->addReference() ？

如果你没有addReference()，你就不能getReference()

【讨论】：

实际上是的，我应该在插入视频数据夹具时调用 addReference() 并添加 Video 作为参考，然后调用 getReference() 谢谢
