我在 PostCategory 和 SubCategory 之间有一个多对一的关系，如下所示：
子类别实体：
namespace VisualImmersion\AdminBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* SubCategory
*
* @ORM\Table(name="post_category_subcategory")
* @ORM\Entity(repositoryClass="VisualImmersion\AdminBundle\Entity\Repository\SubCategoryRepository")
*/
class SubCategory
{
/**
* @var integer
*
* @ORM\Column(name="ID", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* @ORM\ManyToOne(targetEntity="\VisualImmersion\AdminBundle\Entity\PostCategory", cascade={"remove", "persist"}, inversedBy="subCategories")
* @ORM\JoinColumn(referencedColumnName="ID")
*/
private $postCategory;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return SubCategory
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set category
*
* @param \VisualImmersion\AdminBundle\Entity\PostCategory $category
*/
public function setPostCategory(\VisualImmersion\AdminBundle\Entity\PostCategory $category)
{
$this->postCategory = $category;
}
/**
* Get category
*
* @return \VisualImmersion\AdminBundle\Entity\PostCategory
*/
public function getPostCategory()
{
return $this->postCategory;
}
}
PostCategory 实体：
<?php
namespace VisualImmersion\AdminBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* PostCategory
*
* @ORM\Table(name="post_category")
* @ORM\Entity(repositoryClass="VisualImmersion\AdminBundle\Entity\Repository\PostCategoryRepository")
*/
class PostCategory
{
/**
* @var integer
*
* @ORM\Column(name="ID", type="integer", nullable=false)
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="name", type="string", length=45, nullable=false)
*/
private $name;
/**
* @ORM\ManyToMany(targetEntity="Post", mappedBy="posts")
*/
private $posts;
/**
* @ORM\OneToMany(targetEntity="SubCategory", mappedBy="postCategory", cascade={"remove", "persist"})
*/
protected $subCategories;
public function __construct()
{
$this->posts = new \Doctrine\Common\Collections\ArrayCollection();
$this->subCategories = new \Doctrine\Common\Collections\ArrayCollection();
}
public function __toString()
{
return (String) $this->id;
}
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return PostCategory
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Add post
*
* @param \VisualImmersion\AdminBundle\Entity\Post $post
*/
public function addPost(\VisualImmersion\AdminBundle\Entity\Post $post)
{
$this->posts[] = $post;
}
/**
* Get posts
*
* @return \Doctrine\Common\Collections\ArrayCollection()
*/
public function getPosts()
{
return $this->posts->toArray();
}
/**
* Remove post
*
* @param \VisualImmersion\AdminBundle\Entity\Post $post
*/
public function removePost(\VisualImmersion\AdminBundle\Entity\Post $post)
{
$this->posts->removeElement($post);
}
/**
* Add subCategory
*
* @param \VisualImmersion\AdminBundle\Entity\SubCategory $subCategory
*/
public function addSubCategory(\VisualImmersion\AdminBundle\Entity\SubCategory $subCategory)
{
$this->subCategories[] = $subCategory;
$subCategory->setPostCategory($this);
}
/**
* Get subCategories
*
* @return \Doctrine\Common\Collections\ArrayCollection()
*/
public function getSubCategories()
{
return $this->subCategories;
}
/**
* Set subCategories
*
* @param \Doctrine\Common\Collections\ArrayCollection $subCategories
*/
public function setSubCategories(\Doctrine\Common\Collections\ArrayCollection $subCategories)
{
foreach ($subCategories as $subCategory) {
$subCategory->setPostCategory($this);
}
$this->subCategories = $subCategories;
}
/**
* Remove subCategory
*
* @param \VisualImmersion\AdminBundle\Entity\SubCategory $subCategory
*/
public function removeSubCategory(\VisualImmersion\AdminBundle\Entity\SubCategory $subCategory)
{
$this->subCategories->removeElement($subCategory);
}
}
我嵌入了表单以在 PostCategory 表单上添加子类别的集合：
子类别类型：
<?php
namespace VisualImmersion\AdminBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class SubCategoryType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
;
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'VisualImmersion\AdminBundle\Entity\SubCategory'
));
}
/**
* @return string
*/
public function getName()
{
return 'visualimmersion_adminbundle_subcategorytype';
}
}
帖子类别类型：
<?php
namespace VisualImmersion\AdminBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class PostCategoryType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('subCategories', 'collection', array(
'type' => new SubCategoryType(),
'required' =>false,
'allow_add' => true,
'allow_delete' => true,
'prototype' => true,
'prototype_name' =>'subCategory__name__',
'by_reference' => 'false'
));
}
/**
* @param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'VisualImmersion\AdminBundle\Entity\PostCategory'
));
}
/**
* @return string
*/
public function getName()
{
return 'visualimmersion_adminbundle_postcategorytype';
}
}
我的问题是在数据库中的 subCategory 表中，没有添加 postCategory 外键：
我拼命地寻找解决这个问题的方法，所以我请求你的帮助。
