Question

我最近一直在使用Symfony2，我一直在关注本教程：tutorial.co.symblog.co.uk

不幸的是，由于该教程是很久以前写的，很多事情都是错的。我已经能够通过常识来解决大多数问题，但这个问题很棘手......

我正在创建一个博客，并拥有博客帖子的数据夹具和这些博客帖子的评论。我跑的时候：

php app/console doctrine:fixtures load

我明白了：

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：

如果您还有其他需要，请告诉我，并且一如既往地提前致谢！

在AbstractFixture课程中扩展BlogFixtures：

class BlogFixtures  extends AbstractFixture implements OrderedFixtureInterface{ ... }
