Question

我有Customer实体和两个一对多关系CustomerPhone和CustomerAddress。

Customer实体具有addPhone / removePhone和addAddress / removeAddress“adders”。

CustomerType集合选项具有'by_reference'=＆gt;这两个集合都是假的。

实体函数addPhone / removePhone和在表单提交后未调用的addAddress / removeAddress，因此CustomerPhone和CustomerAddress在持久化后没有父ID。

为什么可以在表单提交时调用addPhone / removePhone和addAddress / removeAddress？

UPD 1。

@Baig suggestion之后我现在调用了addPhone / removePhone“adders”，但是没有添加地址/删除地址。无法理解，因为它们完全相同。

 # TestCustomerBundle/Entity/Customer.php

 /**
 * @var string
 *
 * @ORM\OneToMany(targetEntity="CustomerPhone", mappedBy="customerId", cascade={"persist"}, orphanRemoval=true)
 */
private $phone;

/**
 * @var string
 *
 * @ORM\OneToMany(targetEntity="CustomerAddress", mappedBy="customerId", cascade={"persist"}, orphanRemoval=true)
 */
private $address;

相同文件“adders”

# TestCustomerBundle/Entity/Customer.php
/**
 * Add customer phone.
 *
 * @param Phone $phone
 */
public function addPhone(CustomerPhone $phone) {
    $phone->setCustomerId($this);
    $this->phone->add($phone);

    return $this;
}

/**
 * Remove customer phone.
 *
 * @param Phone $phone customer phone
 */
public function removePhone(CustomerPhone $phone) {
    $this->phone->remove($phone);
}
/**
 * Add customer address.
 *
 * @param Address $address
 */
public function addAddress(CustomerAddress $address) {
    $address->setCustomerId($this);
    $this->address->add($address);

    return $this;
}

/**
 * Remove customer address.
 *
 * @param Address $address customer address
 */
public function removeAddress(CustomerAddress $address) {
    $this->address->remove($address);
}

关系：

# TestCustomerBundle/Entity/CustomerPhone.php
/**
 * @ORM\ManyToOne(targetEntity="Customer", inversedBy="phone")
 * @ORM\JoinColumn(name="customer_id", referencedColumnName="id")
 **/
private $customerId;

#TestCustomerBundle/Entity/CustomerAddress.php
/**
 * @ORM\ManyToOne(targetEntity="Customer", inversedBy="address")
 * @ORM\JoinColumn(name="customer_id", referencedColumnName="id")
 **/
private $customerId;

CustomerType表单：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('name')
        ->add('phone', 'collection', array(
            'type' => new CustomerPhoneType(),
            'allow_add' => true,
            'allow_delete' => true,
            'by_reference' => false,
            'options' => array('label' => false)
        ))
        ->add('address', 'collection', array(
            'type' => new CustomerAddressType(),
            'allow_add' => true,
            'allow_delete' => true,
            'by_reference' => false,
            'options' => array('label' => false)
        ))
        ->add('submit', 'submit')
    ;
}

控制器。

# TestCustomerBundle/Controller/DefaultController.php

public function newAction(Request $request)
    {
        $customer = new Customer();
        // Create form.
        $form = $this->createForm(new CustomerType(), $customer);
        // Handle form to store customer obect with doctrine.
        if ($request->getMethod() == 'POST')
        {
            $form->bind($request);
            if ($form->isValid())
            {
                /*$em = $this->get('doctrine')->getEntityManager();
                $em->persist($customer);
                $em->flush();*/
                $request->getSession()->getFlashBag()->add('success', 'New customer added');
            }
        }
        // Display form.
        return $this->render('DeliveryCrmBundle:Default:customer_form.html.twig', array(
            'form' => $form->createView()
        ));
    }

UPD 2。 测试addAddress是否被调用。

/**
     * Add customer address.
     *
     * @param Address $address
     */
    public function addAddress(Address $address) {
        jkkh; // Test for error if method called. Nothing throws.
        $address->setCustomerId($this);
        $this->address->add($address);        
    }

Answer 1

这个答案对应于Symfony 3，但我相信这也适用于Symfony 2。此答案更多是作为参考，而不是特别解决OP的问题（我不清楚）

在..Symfony/Component/PropertyAccess/PropertyAccessor.php上，方法writeProperty负责调用setXXXXs或addXXX＆amp; removeXXXX方法。

所以这里是它寻找方法的顺序：

如果实体是array或Traversable的实例（ArrayCollection是），那么

addEntityNameSingular()

removeEntityNameSingular()

参考资料来源：

if (is_array($value) || $value instanceof \Traversable) {
    $methods = $this->findAdderAndRemover($reflClass, $singulars);

    if (null !== $methods) {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_ADDER_AND_REMOVER;
        $access[self::ACCESS_ADDER] = $methods[0];
        $access[self::ACCESS_REMOVER] = $methods[1];
    }
}

如果没有，那么：

setEntityName()
entityName()
__set()
$entity_name（应公开）

__call()

参考资料来源：

if (!isset($access[self::ACCESS_TYPE])) {
    $setter = 'set'.$camelized;
    $getsetter = lcfirst($camelized); // jQuery style, e.g. read: last(), write: last($item)

    if ($this->isMethodAccessible($reflClass, $setter, 1)) {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_METHOD;
        $access[self::ACCESS_NAME] = $setter;
    } elseif ($this->isMethodAccessible($reflClass, $getsetter, 1)) {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_METHOD;
        $access[self::ACCESS_NAME] = $getsetter;
    } elseif ($this->isMethodAccessible($reflClass, '__set', 2)) {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_PROPERTY;
        $access[self::ACCESS_NAME] = $property;
    } elseif ($access[self::ACCESS_HAS_PROPERTY] && $reflClass->getProperty($property)->isPublic()) {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_PROPERTY;
        $access[self::ACCESS_NAME] = $property;
    } elseif ($this->magicCall && $this->isMethodAccessible($reflClass, '__call', 2)) {
        // we call the getter and hope the __call do the job
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_MAGIC;
        $access[self::ACCESS_NAME] = $setter;
    } else {
        $access[self::ACCESS_TYPE] = self::ACCESS_TYPE_NOT_FOUND;
        $access[self::ACCESS_NAME] = sprintf(
            'Neither the property "%s" nor one of the methods %s"%s()", "%s()", '.
            '"__set()" or "__call()" exist and have public access in class "%s".',
            $property,
            implode('', array_map(function ($singular) {
                return '"add'.$singular.'()"/"remove'.$singular.'()", ';
            }, $singulars)),
            $setter,
            $getsetter,
            $reflClass->name
        );
    }
}

为了回答OP的问题，基于上述信息，symfony的PropertyAccessor类无法正确读取您的addXX和removeXX方法。可能的原因可能是未被识别为必须从实体的构造函数完成的array或ArrayCollection

public function __construct() {
     $this->address = new ArrayCollection();
     // ....
}

Answer 2

对我来说，这最终通过添加getXXX来解决，PropertyAccessor将集合返回到addXXX。如果没有这个，你会继续想知道为什么removeXXX或by_reference没有被调用。

所以请确保：

选项false在字段

adder

您在关系的拥有方拥有remover和getter方法，
PropertyAccessor可以访问by_reference，以检查是否可以使用prototype，
如果您想使用allow_add来处理通过Javascript添加/删除的问题，请确保将true设置为case_insensitive_equals。

Answer 3

我有同样的问题，但我不确定这是同一个原因。

我的实体属性具有OneToMany关系，最后必须有's'。所以在“handleRequest”（留下一个黑盒子，我没有在里面查找），symfony会发现你的“addxxx”没有“s”。

在示例'Task - Tag'中，他声明了“tags”但是getTag。

在您的情况下，我认为您将$ phone更改为$ phone，方法如下：

public function setPhones($phones){}
public function addPhone(Phone $phone){}

对于您的表单搜索方法的名称，只需删除您实体中的临时设置者并提交您的表单，symfony会告诉您。

希望这会帮助你：）

Symfony2表单集合不调用addxxx和removexxx，即使'by_reference'=＆gt;假
