Symfony2 ORM prePersist không hoạt động

Question

phương thức prePersist() của thực thể của tôi không được gọi.

Đây là mã của tôi Mẫu/UsersType.php

<?php 
namespace Acme\DemoBundle\Form; 

use Symfony\Component\Form\AbstractType;

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'; 
    } 
} 

tôi đã nhận xét ra ba lĩnh vực hoạt động, tạo ra và sửa đổi để không hiển thị chúng trong biểu mẫu.

Nhưng tôi đang nhận được lỗi:

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]: 

gì tôi đang mất tích trong Entity?

Answer 1

Một vấn đề là chức năng này.

/** 
* Set active 
* 
* @ORM\PrePersist 
* @param boolean $active 
* @return Users 
*/ 
public function setActive($active) 
{ 
    $this->active = $active; 

    return $this; 
} 

Bạn không thể chuyển đối số cho các hàm khi sử dụng @PrePersist.

Ngoài ra chức năng này

/** 
* @ORM\PrePersist 
* @ORM\PreUpdate 
*/ 
public function prePersist(){ 

    $this->active = 0; 
    $this->created = date('Y-m-d H:i:s'); 
    $this->modified = date('Y-m-d H:i:s'); 

} 

thất bại bởi vì bạn đang gán một giá trị chuỗi lĩnh vực DateTime. Hãy thử điều này:

/** 
* @ORM\PrePersist 
* @ORM\PreUpdate 
*/ 
public function prePersist() 
{ 

    $this->active = false; 
    $this->created = new \DateTime(); 
    $this->modified = new \DateTime(); 

} 

Answer 2

@ORM\PrePersist là thiếu ngoặc, nó phải là @ORM \ PrePersist()

Answer 3

Tôi có cùng một vấn đề. Theo tài liệu, bạn phải bật gọi lại vòng đời http://symfony.com/doc/current/book/doctrine.html

/** 
* @ORM\Entity() 
* @ORM\HasLifecycleCallbacks() 
*/ 
class Product 
{ 
    // ... 
}
