Question

我在symfony2的多个嵌入表单上有一个奇怪的错误。

这是我的结构：

被许可人＆lt; - OneToMany - ＆gt;注册＆lt; - OneToMany - ＆gt;付款

许可：

/**
 * @ORM\OneToMany(targetEntity="cM\ManagementBundle\Entity\Registration", mappedBy="licensee", cascade={"persist" })
 */
private $registrations;

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

public function addRegistration(\cM\ManagementBundle\Entity\Registration $registration)
{
    $this->registrations[] = $registration;
    $registration->setLicensee($this);

    return $this;
}

public function removeRegistration(\cM\ManagementBundle\Entity\Registration $registration)
{
    $this->registrations->removeElement($registration);
}

public function setRegistrations(ArrayCollection $registrations)
{
    foreach ($registrations as $registration) {
        $registration->addLicensee($this);
    }

    $this->registrations = $registrations;
}

public function getRegistrations() {
    return $this->registrations;
}

注册：

/**
 * @ORM\ManyToOne(targetEntity="cM\ManagementBundle\Entity\Licensee", inversedBy="registrations")
 * @ORM\JoinColumn(nullable=false)
 */
private $licensee;

/**
 * @ORM\OneToMany(targetEntity="cM\ManagementBundle\Entity\Payment", mappedBy="registration", cascade={"ALL"}, orphanRemoval=true)
 * @ORM\JoinColumn(nullable=false)
 */
private $payments;

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

/**
 * Set licensee
 *
 * @param \cM\ManagementBundle\Entity\Licensee $licensee
 * @return Registration
 */
public function setLicensee(\cM\ManagementBundle\Entity\Licensee $licensee)
{
    $this->licensee = $licensee;

    return $this;
}

/**
 * Get licensee
 *
 * @return \cM\ManagementBundle\Entity\Licensee 
 */
public function getLicensee()
{
    return $this->licensee;
}

/**
 * Add payments
 *
 * @param \cM\ManagementBundle\Entity\Payment $payment
 * @return Registration
 */
public function addPayment(\cM\ManagementBundle\Entity\Payment $payment)
{
    $payment->setRegistration($this);
    $this->payments[] = $payment;

    return $this;
}

/**
 * Remove payments
 *
 * @param \cM\ManagementBundle\Entity\Payment $payment
 */
public function removePayment(\cM\ManagementBundle\Entity\Payment $payment)
{
    $this->payments->removeElement($payment);
}

/**
 * Get payments
 *
 * @return \Doctrine\Common\Collections\Collection 
 */
public function getPayments()
{
    return $this->payments;
}

付款：

/**
 * @ORM\ManyToOne(targetEntity="cM\ManagementBundle\Entity\Registration", inversedBy="payments")
 * @ORM\JoinColumn(nullable=false, onDelete="CASCADE")
 */
private $registration;

/**
 * Set registration
 *
 * @param \cM\ManagementBundle\Entity\Registration $registration
 * @return Payment
 */
public function setRegistration(\cM\ManagementBundle\Entity\Registration $registration)
{
    $this->registration = $registration;

    return $this;
}

/**
 * Get registration
 *
 * @return \cM\ManagementBundle\Entity\Registration 
 */
public function getRegistration()
{
    return $this->registration;
}

LicenseeType ：

$builder
        ->add('registrations', 'collection', array(
            'type'         => new RegistrationType(),
            'allow_add'    => true,
            'by_reference' => false,
        ))

RegistrationType ：

$builder
        ->add('payments', 'collection', array(
            'type'         => new PaymentType(),
            'allow_add'    => true,
            'allow_delete' => true,
            'by_reference' => false,
            'required'     => false,
        ))

PaymentType ：

$builder
        ->add('amount', 'text')

我的主控制器： LicenseeController

$form = $this->createForm('cm_managementbundle_licensee', $licensee);
$form->handleRequest($this->getRequest());

if ($this->getRequest()->getMethod() === 'POST') {
    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($licensee);

        $em->flush();

        return $this->redirect($this->generateUrl('homepage'));
    }
}

在被许可方表格中，注册是强制性的，但付款是可选项。

当我创建一个包含注册信息且没有付款的新被许可人时：其确定并且信息已妥善保存在数据库中
当我编辑被许可人并添加一些付款时：确定
当我创建一个包含注册信息且一个或多个付款的新被许可人时，存在一个说明注册不能为空的原则错误：

使用params [null，null，...]执行'INSERT INTO Registration（registrationDate，registrationNumber，...）VALUES（？，？，...）'时发生异常：

SQLSTATE [23000]：完整性约束违规：1048列'registrationDate'不能为空

当我查看symfony profiler时，我看到该doctrine启动2个查询注册表：

- "START TRANSACTION"
- INSERT INTO Licensee (lastname, firstname, ...) VALUES (?, ?, ...)
Parameters: { 1: Simpson, 2: Homer, ... }
- INSERT INTO Registration (registrationDate, registrationNumber, ...) VALUES (?, ?, ...)
Parameters: { 1: '2015-01-29 00:00:00', 2: '1234', ... }
- INSERT INTO Registration (registrationDate, registrationNumber, ...) VALUES (?, ?, ...)
Parameters: { 1: null, 2: null, ... }

播种为什么第二个注册查询的所有参数都为null而第一个是正确的？

我缺少什么？

感谢任何帮助之王。

好的，设法解决了这个问题。

我必须更改付款收集的原型名称

->add('payments', 'collection', array(
    'type' => new PaymentType(),
    'allow_add' => true,
    'prototype_name' => 'payments_name'
))

所以当我在添加新的付款时用javascript动态更改名称时，我不会在过程中更改父名称（注册）（默认情况下，所有原型集合都具有相同的名称（名称）
