我正在尝试embed a collection of forms,但我无法持久保存新创建的对象。
Customer
有很多Email
个。在我的控制器中,
// CustomersController.php
$customer = new Customer();
$customer->setCreatedBy(0);
$blankEmail = new Email();
$customer->addEmail($blankEmail);
$form = $this->createForm(new CustomerType(), $customer);
我确实记得在我的Customer
课程中设置了级联选项:
// Customer.php
...
/**
* @ORM\OneToMany(targetEntity="Email", mappedBy="customer", cascade={"persist"})
*/
protected $emails;
我的Email
课程也有必要的信息:
// Email.php
...
/**
* @ORM\ManyToOne(targetEntity="Customer", inversedBy="emails", cascade={"persist"})
* @ORM\JoinColumn(name="customers_id", referencedColumnName="id")
*/
protected $customer;
出于某种原因,这不起作用:
if ($request->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($customer);
$em->flush();
它增加了客户,但是当它试图添加电子邮件时,它说没有设置customerId。所以,我试过这个,它的确有效:
if ($request->isMethod('POST')) {
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
foreach ($customer->getEmails() as $email)
$email->setCustomer($customer);
$em->persist($email);
}
$em->persist($customer);
$em->flush();
但我真的希望能够一举得到它,只需坚持$customer
对象(我知道它可以)。
答案 0 :(得分:1)
尝试更改Customer类中的默认“addEmail”方法。
此方法应如下所示:
public function addEmail($email)
{
$email->setCustomer($this);
$this->emails[] = $email;
return $this;
}
