Symfony 2 Doctrine:Fixtures:Load Undefined Index

Question

我最近一直在使用Symfony2，我一直在遵循本教程：tutorial.co.symblog.co.uk

不幸的是，由于教程是很久以前编写的，因此很多事情都是错误的。我已经能够通过运用常识来解决其中的大部分问题，但这个很棘手......

我正在创建一个博客，并为博客文章提供数据固定装置，并对这些博客文章发表评论。当我运行时：

php app/console doctrine:fixtures load

我得到：

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

以下是我的博客装置：

如果您需要其他任何东西，请告诉我，一如既往，提前感谢！

在BlogFixtures类中扩展AbstractFixture：

class BlogFixtures  extends AbstractFixture implements OrderedFixtureInterface{ ... }
