php-可捕获的致命错误：传递给(…)的参数1必须是给定()整数的实例

我正在制作固定装置,尝试加载它们时出现错误.我需要一个Movie对象的实例,但是我给出的(我不知道为什么)是整数.因此,它告诉我出现以下错误：

 [Symfony\Component\Debug\Exception\ContextErrorException]
 Catchable Fatal Error: Argument 1 passed to Filmboot\MovieBundle\Document\A
 ward::setMovie() must be an instance of Filmboot\MovieBundle\Document\Movie
 , integer given, called in C:\Programming\xampp\htdocs\filmboot.web\src\Fil
 mboot\MovieBundle\DataFixtures\MongoDB\Awards.php on line 143 and defined i
 n C:\Programming\xampp\htdocs\filmboot.web\src\Filmboot\MovieBundle\Documen
 t\Award.php line 107

这是我的夹具类：

namespace Filmboot\MovieBundle\DataFixtures\MongoDB;

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

use Filmboot\MovieBundle\Document\Award;

class Awards extends AbstractFixture implements OrderedFixtureInterface {
    public function load(ObjectManager $manager) {
        $awards = array(
            array(
                "name"     => "Sitges",
                "year"     => "1992",
                "category" => "Best director"
        );

        foreach ($awards as $award) {
            $document = new Award();
            $document->setName    ($award["name"]);
            $document->setYear    ($award["year"]);
            $document->setCategory($award["category"]);

            $manager->persist($document);
            $this->addReference("award-" .$i, $award);

        }

        $manager->flush();
    }
    public function getOrder() {
        return 1;
    }
}

这是文档类：

namespace Filmboot\MovieBundle\Document;

use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;
use Doctrine\Common\Collections\ArrayCollection;
use Filmboot\MovieBundle\Util;

/**
 * @ODM\Document(db="filmbootdb", collection="awards")
 * @ODM\Document(repositoryClass="Filmboot\MovieBundle\Document\AwardRepository")
 */
class Award {
    /**
     * @ODM\Id
     */
    private $id;

    /**
     * @ODM\String
     */
    private $name;

    /**
     * @ODM\Int
     */
    private $year;

    /**
     * @ODM\String
     */
    private $category;


    /**
     * @ODM\ReferenceOne(targetDocument="Movie", mappedBy="awards", cascade={"persist"})
     */
    private $movie;



    public function getId()        {
        return $this->id;
    }

    public function setName($name) {
        return $this->name = $name;
    }

    public function getName()      {
        return $this->name;
    }

    public function setYear($year) {
        return $this->year = $year;
    }

    public function getYear()      {
        return $this->year;
    }

    public function setCategory($category) {
        return $this->category = $category;
    }

    public function getCategory()  {
        return $this->category;
    }    

    public function setMovie(\Filmboot\MovieBundle\Document\Movie $movie)   {
        $movie->setAward($this);
        return $this->movie = $movie;
    }

}

解决方法:

如我们所见,您明确为电影指定了一个整数：

$awards = array(
            array(
                // ...
                "movie"    => 1,
            ),
          );

// ...

$document->setMovie   ($award["movie"]);

脚本而不是电影对象会崩溃,因为它需要一个电影对象：

public function setMovie(\Filmboot\MovieBundle\Document\Movie $movie)   {
    return $this->movie = $movie;
}

因此,解决方案是创建电影的固定装置,并将其设置为reference：

// When saving inside Movie fixtures
$manager->persist($movie);
$manager->flush();
$this->addReference('movie-'.$i, $movie); // Give the references as movie-1, movie-2...

然后首先使用getOrder()方法加载它们：

public function getOrder()
{
    return 0; // 0, loaded first
}

控制在电影之后加载奖项：

public function getOrder()
{
    return 1; // loaded after 0...
}

然后在您的Award灯具中通过引用检索它们之后,它将加载整个对象,而不仅仅是id(整数)：

$awards = array(
            array(
                // ...
                "movie"    => $this->getReference('movie-1'), // Get the Movie object, not just id
            ),
          );

// ...

$document->setMovie   ($award["movie"]);

请注意,如果要使用参考和订单,则灯具类需要实现OrderedFixtureInterface：

namespace Acme\HelloBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Acme\HelloBundle\Entity\Group;

class LoadGroupData extends AbstractFixture implements OrderedFixtureInterface

您必须对所有其他实体(例如演员,导演)执行此操作.

您可以找到在夹具here之间共享对象(通过参考)的文档.

编辑：

使双向工作,适应奖项制定者：

public function setMovie(\Filmboot\MovieBundle\Document\Movie $movie)   {
    $movie->setAward($this);
    return $this->movie = $movie;
}

并使用级联持久性来适应持久性：

/**
 * @ODM\ReferenceOne(targetDocument="Movie", mappedBy="awards", cascade={"persist"})
 */
private $movie;
