我有两个与此问题相关的实体,我希望连接表能够在每个表中交叉引用值。
以下是解释:
实体ContainerType.php:
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use AppBundle\Entity\Containers;
/**
* ContainerType
*
* @ORM\Table(name="container_type")
* @ORM\Entity
* @ORM\HasLifecycleCallbacks()
*/
class ContainerType
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="type", type="string", length=255)
*/
private $type;
/**
* @var \DateTime
*
* @ORM\Column(name="date_added", type="datetime")
*/
private $dateAdded;
/**
* @var \DateTime
*
* @ORM\Column(name="date_modified", type="datetime", nullable=true)
*/
private $dateModified;
/**
* @ORM\ManyToMany(targetEntity="Containers", inversedBy="type")
* @ORM\JoinTable(name="container_type_containers")
**/
private $container;
public function __construct()
{
$this->container = new ArrayCollection();
}
实体Containers.php:
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use AppBundle\Entity\ContainerType;
/**
* Containers
*
* @ORM\Table(name="containers")
* @ORM\Entity
*/
class Containers
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="number", type="string", length=255)
*/
private $number;
/**
* @ORM\ManyToMany(targetEntity="Containers", mappedBy="container")
*/
private $type;
public function __construct()
{
$this->type = new ArrayCollection();
}
虽然架构更新没有问题,但当我做一个学说:架构:验证我得到以下失败:
[Mapping] FAIL - The entity-class 'AppBundle\Entity\Containers' mapping is invalid:
* The association AppBundle\Entity\Containers#type refers to the owning side field AppBundle\Entity\Containers#container which does not exist.
但是$ Container字段存在于ContainerType中,所以我不明白为什么它试图在Containers实体中引用一个名为container的字段?
任何人都可以对此有所了解吗?
谢谢 迈克尔

我认为这段代码应该适合你:)
ContainerType.php
/**
* @ORM\ManyToMany(targetEntity="Containers", inversedBy="containersType")
* @ORM\JoinTable(name="container_type_containers",
* joinColumns={@ORM\JoinColumn(name="container_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM\JoinColumn(name="container_type_id", referencedColumnName="id")})
*/
protected $containers;
Containers.php
/**
* @ORM\ManyToMany(targetEntity="ContainerType", mappedBy="containers")
*/
protected $containersType;

我刚刚意识到我的错误!
我在Containers.php文件中使用了错误的目标实体,我应该使用ContainerType作为目标,而不是容器,这就是为什么它试图在错误的表中找到该字段的原因!
