我的实体的 prePersist() 方法没有被调用。
<?php

这是我的 Form/UsersType.php 代码
<?php
namespace Acme\DemoBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class UsersType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('username','text', array('required' => true))
->add('firstname','text', array('required' => true))
->add('lastname','text', array('required' => true))
->add('email', 'email', array('label' => 'E-Mail'))
->add('password', 'password', array('label' => 'Password'))
->add('password_confirmation', 'password', array('mapped' => false)) // Added virtual field on form
/*
->add('active','hidden',array('data' => ''))
->add('created','hidden',array('data' => ''))
->add('modified','hidden',array('data' => ''))
*
*/
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Acme\DemoBundle\Entity\Users'
));
}
public function getName()
{
return 'acme_demobundle_userstype';
}
}
我已经注释掉了这三个处于事件状态、创建和修改的字段，以便不在表单中显示它们。
但我收到错误:
An exception occurred while executing 'INSERT INTO users (username, firstname, lastname, email, password, active, created, modified) VALUES (?, ?, ?, ?, ?, ?, ?, ?)' with params ["neeraj", "neeraj", "kumar", "neeraj.kumar@test.com", "p@ssw0rd", null, null, null]:
我在实体中缺少什么？
堆栈跟踪

最佳答案
我也有同样的问题。根据文档，您必须启用生命周期回调 http://symfony.com/doc/current/book/doctrine.html
/**
* @ORM\Entity()
* @ORM\HasLifecycleCallbacks()
*/
class Product
{
// ...
}
关于Symfony2 ORM prePersist 不工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17992549/
