我一直是LoadAdvert类上的ContainerAwareInterface，所以我可以调用并使用EntityManager来检索数据库中的用户。
但是，当执行 php bin/console doctrine：fixtures：load 时，实体管理器只检索一个空数组，就好像数据库中没有用户一样。
<?php
// src/OC/PlatformBundle/DataFixtures/ORM/LoadCategory.php
namespace OC'PlatformBundle'DataFixtures'ORM;
use Doctrine'Common'DataFixtures'FixtureInterface;
use Doctrine'Common'Persistence'ObjectManager;
use Symfony'Component'DependencyInjection'ContainerAwareInterface;
use Symfony'Component'DependencyInjection'ContainerInterface;
use OC'PlatformBundle'Entity'Advert;
use OC'UserBundle'Entity'User;
class LoadAdvert implements FixtureInterface, ContainerAwareInterface
{
/**
* @var ContainerInterface
*/
private $container;
public function setContainer(ContainerInterface $container = null)
{
$this->container = $container;
}
// Dans l'argument de la méthode load, l'objet $manager est l'EntityManager
public function load(ObjectManager $manager)
{
$em = $this->container->get('doctrine.orm.entity_manager');
$author = $em->getRepository('OCUserBundle:User')->findAll();
die(var_dump($author));
这就是我的做法。最主要的是为您创建的用户对象设置引用，然后在其他夹具文件中调用它并将它们分配给相关对象。夹具数据的执行顺序也很重要。在加载用户之前，无法加载相关对象。
namespace AcmeBundle'DataFixtures'ORM;
use Doctrine'Common'DataFixtures'AbstractFixture;
use Doctrine'Common'DataFixtures'OrderedFixtureInterface;
use Doctrine'Common'Persistence'ObjectManager;
use Symfony'Component'DependencyInjection'ContainerAwareInterface;
use Symfony'Component'DependencyInjection'ContainerInterface;
class LoadUserData extends AbstractFixture implements OrderedFixtureInterface, ContainerAwareInterface
{
/** @var ContainerInterface */
private $container;
/**
* Load data fixtures with the passed EntityManager
*
* @param ObjectManager $manager
*/
public function load(ObjectManager $manager)
{
$userManager = $this->container->get('fos_user.user_manager');
$user1 = $userManager->createUser();
$user1->setUsername('username1');
$user1->setPlainPassword('123');
$user1->setEmail('example1@gmail.com');
$user1->setEnabled(true);
$user2 = $userManager->createUser();
$user2->setUsername('username2');
$user2->setPlainPassword('123');
$user1->setEmail('example2@gmail.com');
$user2->setEnabled(true);
$manager->persist($user1);
$manager->persist($user2);
$this->setReference('user1', $user1);
$this->setReference('user2', $user2);
$manager->flush();
}
/**
* Get the order of this fixture
*
* @return integer
*/
public function getOrder()
{
return 1;
}
/**
* Sets the Container. Need it to create new User from fos_user.user_manager service
*
* @param ContainerInterface|null $container A ContainerInterface instance or null
*/
public function setContainer(ContainerInterface $container = null)
{
$this->container = $container;
}
}
然后在其他夹具文件中，您不会像从数据库那样调用用户，而是这样做：
$author = $this->getReference('user1');
$article = new Article();
$article->addAuthor($author);
然后将此$author对象添加到相关对象。
请记住在此article装置中实现OrderedFixtureInterface，并将getOrder()设置为高于users的数字。
