Symfony 赢得'；它们不会按给定的顺序加载，而是按字母顺序加载

据我所知，fixture将根据每个fixture文件的

getOrder（）

方法中返回的值按给定顺序加载。出于某种原因，条令试图以字母顺序（类名）加载下面的装置

---

在下面的示例中，它必须按Student、Subject和StudentSubject顺序加载，但它尝试加载Student、StudentSubject和Subject，这会导致问题，因为StudentSubject不能在Student和Subject之前存在。关联：

Student（1->N）StudentSubject（N将
FixtureInterface
的实例替换为
OrderedFixtureInterface

例如：

使用条令\Common\DataFixtures\OrderedFixtureInterface；

class StudentFixtures extends AbstractFixture implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        ......
        $this->addReference('student-1', $student);
        ......
    }

    public function getOrder() { return 1; }
}

class SubjectFixtures extends AbstractFixture implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        ......
        $this->addReference('subject-1', $subject);
        ......
    }

    public function getOrder() { return 2; }
}

class StudetSubjectFixtures extends AbstractFixture implements FixtureInterface
{
    public function load(ObjectManager $manager)
    {
        ......
        $student = $this->getReference('student-1');
        $subject = $this->getReference('subject-1');
        ......
    }

    public function getOrder() { return 3; }
}
