Fatal Error when using Fixtures with Doctrine 2

Question

I am a Symblog 2 beginner and I'm following this tutorial for Symblog2.

I have created my Data Model and tried to populate test data to my DB using Doctrine 2 fixtures.

I downloaded the necessary packages and added the following to my autoload.php:

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

and the follwing to AppKernel.php:

new Symfony\Bundle\DoctrineFixturesBundle\DoctrineFixturesBundle(),

My fixtures class looks like this:

<?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();
    }
}

When i try to run php app/console doctrine:fixtures:load, I'm getting the following Exception:

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

I understand the error message, but in my opinion, my load() method is compatible with the FixtureInterface::load.

Could someone tell me, what I'm missing? I followed the tutorial step by step.

Answer 1

The FixtureInterface::load() method has a type hint since v1.0.0-ALPHA2:

use Doctrine\Common\Persistence\ObjectManager;

function load(ObjectManager $manager);

Answer 2

You should add the ObjectManager dependency:

use Doctrine\Common\Persistence\ObjectManager;
