Question

我需要一些帮助，我在学说2中使用ZF2。我有一个实体：带孩子的TaFoo：TaBar（ArrayCollection）。 TaBar还有子代：ATypeBar（ArrayCollection）与TypeBar相关联。我使用FieldSets添加多个TaBar，并且在每个TaBar上我想添加多个ATypeBars。

但是当我保存时：

TaFoo是创建并保存
TaBar也创建并保存
TaTypeBar仅保存最后一个集合

我没有任何错误，但收藏品中的第一个永远不会保存。

实体： TaFoo

  class TaFoo{
        /**
         * @var integer
         * @ORM\Column(name="ID_FOO", type="integer", nullable=false)

         * @ORM\SequenceGenerator(sequenceName="TA_FOO_ID_FOO_seq", allocationSize=1, initialValue=1)
         */

        private $idFoo;
        /**
         * Get idFoo
         *
         * @return integer
         */
        public function getIdFoo()
        {
            return $this->idFoo;
        }

        /**
        * @ORM\OneToMany(targetEntity="TaBar", mappedBy="idFoo", cascade={"persist", "remove"}, orphanRemoval=true)
         **/
        private $idBar;

        {
            return $this->idBar;
        }

        {
            foreach ($idBars as $idBar) {
                $idBar->setIdFoo(null);
                $this->idBar->removeElement($idBar);
            }
        }
         /**

                $this->idBar->add($idBar);
            }

FieldSet中 TaFoo Fieldset

        'label' => 'add a bar',
        'count' => 0,
        'allow_remove' => true,
        'allow_add' => true,
        'target_element' => new BarFieldset($entityManager, $userNumeroOrga),
    )
));
$this->get('idBar')->setHydrator(new DoctrineHydratorDateTimeFr($entityManager));

BarFieldset

*[..HERE: Some Elements, they work..]*
$this->add(array(
    'type' => 'Zend\Form\Element\Collection',
    'name' => 'idATypeBars',
    'options' => array(
        'tab' => 'Bar',
        'label' => 'add a TypeBar',
        'count' => 1,
        'allow_remove' => true,
        'allow_add' => true,
        'target_element' => new TypeBarFieldset($entityManager),
    )
));

控制器 FooController的

    $request = $this->getRequest();
    $idFoo = (int) $this->params()->fromRoute('id', 0);
    if ($request->isPost()) {
        $idFoo = $this->params()->fromPost('idFoo');
    }

    $taFoo = $this->getEntityManager()->find('\Application\Entity\TaFoo', $idFoo);
    $form = new FooForm($this->getEntityManager(), $this->getUserNum());
    $form->bind($taFoo);

    if ($request->isPost()) {

        $post = $request->getPost();

        $config = $this->getServiceLocator()->get('config');
        $fieldset = $config['fieldset'];

        $form->setData($post);

        if ($form->isValid()) {

            $this->getEntityManager()->persist($taFoo);
            $this->getEntityManager()->flush();

            echo ('ok');
            exit();
        }

        echo '-1: ';
        print_r($form->getMessages());
        exit();

我已经在$ request-＆gt; getPost中检查数据是否正确，这没关系。保存TaFoo / TaBar / AtypeBar / TaTypeBar的所有数据都在。但坚持不能使用TaTypeBar。

Answer 1

您需要在实体类__construct方法中initialize all your collections。

我认为问题在于那里，因为我在$this->idATypeBars实体中看不到TaBar的初始化。

所以添加一个__construct函数，如下所示：

public function __construct(){
    $this->idATypeBars = new ArrayCollection();
}

同时检查其他实体的构造函数。这肯定会引起问题。

Doctrine仅保存最后一个集合
