Doctrine Fixture 数据加载 - 插入中缺少值

Question

我在我的 symfony2/doctrine2 项目中创建了以下具有多对一（一个电路包含一个或多个学校）双向关系的实体（学校和电路）。这是 Schoool.orm.yml and circuit.orm.yml 定义

我正在尝试为每个实体加载相应的数据夹具，如下所示：

 //Circuit Fixture
    public function load(ObjectManager $em) {
            $newCirco = new Circonscription();
            $newCirco->setId(1);
            $newCirco->setLibelle('Circuit1');

            $em->persist($newCirco);
            $em->flush();

            $this->addReference('circo1', $newCirco);
    }


    //School Fixture
     public function load(ObjectManager $em) {
            //Ecoles - Circo 1
            $ecole = new Etablissement();
            $ecole->setRne('0310211L');
            $ecole->setCirconscription($em->merge($this->getReference('circo1')));
            $ecole->setLibelle('FRANCE');
            $ecole->setAdresse('6 AVENUE DE Test');
            $ecole->setTelphone('05xxxxxxxx');
            $ecole->setEmail('xxxxxx@xxxxxxxxe.fr');

            $em->persist($ecole);
            $em->flush();
            $this->addReference('ecole', $ecole);
    }

但是，我从 Doctrine 那里得到了一个 NotNullConstraintViolationException 与完整性违规相关的问题。

 An exception occurred while executing 'INSERT INTO etablissement (rne, libe
  lle, adresse, telphone, email, circo_id) VALUES (?, ?, ?, ?, ?, ?)' with pa
  rams ["0310241U", null, null, null, null, null]:
  SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'libelle' cann
  ot be null

虽然该值已在夹具中定义。这个错误的来源可能是什么？或者为什么由 doctrine 生成的插入内容不包含值？

在你的学校里尝试改变 setCirconscription() 的参数：

 public function load(ObjectManager $em) {

        $ecole = new Etablissement();
        $ecole->setRne('0310211L');
        $ecole->setCirconscription($this->getReference('circo1'));

        /.../

}

并且不要忘记在 School Fixture

之前加载 Circuit Fixture
