Symfony 2 Doctrine:Fixtures:Load Undefined Index

Question

I have been using Symfony2 lately, and I've been following this tutorial: tutorial.co.symblog.co.uk

Unfortunately, since the tutorial was written a long time ago, many things are wrong. I've been able to fix most of them through the employment of common sense, but this one is tricky...

I'm creating a blog, and have Data Fixtures for Blog Posts, and Comments on those Blog Posts. When I run:

php app/console doctrine:fixtures load

I get:

PHP Notice:  Undefined index: blog-1 in /private_html/symfony/symblog/vendor/doctrine/data-fixtures/lib/Doctrine/Common/DataFixtures/ReferenceRepository.php on line 154

Here are my blog fixtures:

<?php
// src/Blogger/BlogBundle/DataFixtures/ORM/BlogFixtures.php

namespace Blogger\BlogBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;

use Blogger\BlogBundle\Entity\Blog;

class BlogFixtures implements OrderedFixtureInterface
{
    /**

    public function load(ObjectManager $manager)
    {

Please let me know if you need anything else, and as always, thanks in advance!

Extend AbstractFixture in BlogFixtures class :

class BlogFixtures  extends AbstractFixture implements OrderedFixtureInterface{ ... }
