我正在处理的应用中有一个Media
实体,该实体与其他几个实体有关联:Speaker
,Tag
,Category
等。
在下面的代码中,我展示了一个用于创建测试数据的夹具。为了设置和分配数据之间的众多关系,显然很长。
public function load(ObjectManager $manager)
{
$videoType = new Mediatype();
$videoType->setName('video');
$videoType->setType('video');
$manager->persist($videoType);
$speaker1 = new Speaker();
$speaker1->setName('Joe Bloggs');
$speaker1->setBiography('Joe Bloggs bio.');
$manager->persist($speaker1);
$category1 = new Category();
$category1->setName('PHP');
$category1->setSlug('php');
$manager->persist($category1);
$tag1 = new Tag();
$tag1->setName('PHPNW');
$tag1->setSlug('phpnw');
$manager->persist($tag1);
$video1 = new Media();
$video1->setMediatype($videoType);
$video1->setSpeakers(
new ArrayCollection(
array(
$speaker1
)
)
);
$video1->setCategories(
new ArrayCollection(
array(
$category1
)
)
);
$video1->setTags(
new ArrayCollection(
array(
$tag1
)
)
);
$video1->setDate(new \Datetime());
$video1->setCreationDate(new \DateTime());
$video1->setTitle('My video about PHP');
$video1->setDescription('A video about PHP!');
$video1->setContent('http://some.video-url.com');
$video1->setLength('20:00:00');
$video1->setRating(2.5);
$video1->setVisits(100);
$video1->setLanguage('EN');
$video1->setHostName('PHP');
$video1->setHostUrl('php');
$video1->setStatus('pub');
$manager->persist($video1);
$manager->flush();
}
现在我想用真实数据替换这个夹具,并在一个夹具中加载十几个Media
实体。我可以复制并粘贴它十几次并更改数据,但这很麻烦,难以维护。是否有一种很好的方法来加载这种相同类型的众多实体?
答案 0 :(得分:3)
我意识到doctrine/data-fixtures捆绑已经完全符合我的要求。
为此,我将每个实体加载到自己的夹具中并使用$this->addReference('admin-user', $user);
$this->getReference('admin-user');
从另一个夹具访问它
加载依赖项的灯具也很容易:
public function getDependencies()
{
// fixture classes that this fixture is dependent on
return array('MyDataFixtures\MyOtherFixture');
}
所以现在我的夹具看起来像这样:
public function load(ObjectManager $manager)
{
$video1 = new Media();
$video1->setMediatype($this->getReference('video'));
$video1->setSpeakers(
new ArrayCollection(
array(
$this->getReference('joe-bloggs')
)
)
);
$video1->setCategories(
new ArrayCollection(
array(
$this->getReference('php')
)
)
);
$video1->setTags(
new ArrayCollection(
array(
$this->getReference('phpnw')
)
)
);
$video1->setDate(new \Datetime());
$video1->setCreationDate(new \DateTime());
$video1->setTitle('My video about PHP');
$video1->setDescription('A video about PHP!');
$video1->setContent('http://some.video-url.com');
$video1->setLength('20:00:00');
$video1->setRating(2.5);
$video1->setVisits(100);
$video1->setLanguage('EN');
$video1->setHostName('PHP');
$video1->setHostUrl('php');
$video1->setStatus('pub');
$manager->persist($video1);
$manager->flush();
}
