Question

我是一名Symblog 2初学者，我正在关注Symblog2的这个教程：http://tutorial.symblog.co.uk/docs/doctrine-2-the-blog-model.html。

我创建了我的数据模型，并尝试使用Doctrine 2灯具将测试数据填充到我的数据库中。

我下载了必要的软件包并将以下内容添加到我的autoload.php：

'Doctrine\\Common\\DataFixtures' => __DIR__.'/../vendor/doctrine-fixtures/lib', 'Doctrine\\Common' => __DIR__.'/../vendor/doctrine-common/lib',

以及AppKernel.php的后续内容：

new Symfony\Bundle\DoctrineFixturesBundle\DoctrineFixturesBundle(),

我的灯具类看起来像这样：

<?php
namespace Soccer\MainBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Soccer\MainBundle\Entity\Team;

class TeamFixtures implements FixtureInterface
{
    public function load($manager)
    {
        $team1 = new Team();
        $team1->setName('Poland');
        $team1->setImg('./img/POL.png');
        $team1->setKitHome('./img/POL_1.png');
        $team1->setKitAway('./img/POL_2.png');
        $manager->persist($team1);

        $manager->flush();
    }
}

当我尝试运行php app/console doctrine:fixtures:load时，我遇到以下异常：

Fatal error: Declaration of Soccer\MainBundle\DataFixtures\ORM\TeamFixtures::load()must be compatible with that of Doctrine\Common\DataFixtures\FixtureInterface::load() in D:\xampp\htdocs\soccertips\em-symfony\src\Soccer\MainBundle\DataFixtures\ORM\TeamFixtures.php on line 8

我理解错误消息，但在我看来，我的load()方法与FixtureInterface::load兼容。

有人可以告诉我，我错过了什么吗？我一步一步地按照教程。

Answer 1

FixtureInterface::load() 方法有一个类型提示，因为v1.0.0-ALPHA2：

use Doctrine\Common\Persistence\ObjectManager;

function load(ObjectManager $manager);

Answer 2

您应该添加ObjectManager依赖项：

use Doctrine\Common\Persistence\ObjectManager;

Answer 3

由于 gview 建议使用Doctrine \ Common \ Persistence \ ObjectManager，因为function load(ObjectManager $manager); ObjectManager需要知道它所对应的类所在的位置。
