我有三张桌子。
带有字段的 item
PK id
title
description
type
created
delete
fk user_id
带有字段的 article
PK item_id (one-to-one with item table),
body
带有字段的 media
PK id
FK item_id (many-to-one with item table)
url
type
mimetype
isexternal
type
表格中的article
字段是值为ITEM, ARTICLE and IMAGE
的ENUM。
实体是自动生成的。因此,最初文章实体不会扩展项目实体。我不得不改变它。
我总是收到这个错误:
Entity 'Beachteam\BeachteamBundle\Entity\Article' has a composite identifier
but uses an ID generator other than manually assigning (Identity, Sequence).
This is not supported.
更新
删除我的类型变量并修复discriminatormap后,我收到此错误:
Property Beachteam\BeachteamBundle\Entity\Item::$type does not exist
这是我更新的物品实体:
<?php
namespace Beachteam\BeachteamBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Item
*
* @ORM\Table(name="item", indexes={@ORM\Index(name="fk_item_user1_idx", columns={"user_id"})})
* @ORM\Entity
* @ORM\InheritanceType("JOINED")
* @ORM\DiscriminatorColumn(name="type", type="string")
* @ORM\DiscriminatorMap({
* "ITEM"="Beachteam\BeachteamBundle\Entity\Item",
* "ARTICLE"="Beachteam\BeachteamBundle\Entity\Article",
* "IMAGE"="Beachteam\BeachteamBundle\Entity\Media"
* })
*/
class Item
{
/**
* @var integer
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ORM\Column(name="title", type="string", length=255, nullable=false)
*/
private $title;
/**
* @var string
*
* @ORM\Column(name="description", type="text", nullable=true)
*/
private $description;
/**
* @var \DateTime
*
* @ORM\Column(name="created", type="datetime", nullable=false)
*/
private $created;
/**
* @var \DateTime
*
* @ORM\Column(name="deleted", type="datetime", nullable=true)
*/
private $deleted;
/**

*
* @ORM\ManyToOne(targetEntity="Beachteam\BeachteamBundle\Entity\User")
* @ORM\JoinColumns({
* @ORM\JoinColumn(name="user_id", referencedColumnName="id")
* })
*/
private $user;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set title
*
* @param string $title
* @return Item
*/
public function setTitle($title)
{
$this->title = $title;
return $this;
}
/**
* Get title
*
* @return string
*/
public function getTitle()
{
return $this->title;
}
/**
* Set description
*
* @param string $description
* @return Item
*/
public function setDescription($description)
{
$this->description = $description;
return $this;
}
/**
* Get description
*
* @return string
*/
public function getDescription()
{
return $this->description;
}
/**
* Set created
*
* @param \DateTime $created
* @return Item
*/
public function setCreated($created)
{
$this->created = $created;
return $this;
}
/**
* Get created
*
* @return \DateTime
*/
public function getCreated()
{
return $this->created;
}
/**
* Set deleted
*
* @param \DateTime $deleted
* @return Item
*/
public function setDeleted($deleted)
{
$this->deleted = $deleted;
return $this;
}
/**
* Get deleted
*
* @return \DateTime
*/
public function getDeleted()
{
return $this->deleted;
}
/**
* Set user
*
* @param \Beachteam\BeachteamBundle\Entity\User $user
* @return Item
*/
public function setUser(User $user)
{
$this->user = $user;
return $this;
}
/**
* Get user
*
* @return \Beachteam\BeachteamBundle\Entity\User
*/
public function getUser()
{
return $this->user;
}
}
这是我更新的文章实体:
<?php
namespace Beachteam\BeachteamBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Item
*
* @ORM\Table(name="article")
* @ORM\Entity
*/
class Article extends Item
{
/**
* @var string
*
* @ORM\Column(name="body", type="text")
*/
protected $body;
/**
* Set body
*
* @param string $body
* @return Article
*/
public function setBody($body)
{
$this->body = $body;
return $this;
}
/**
* Get body
*
* @return string
*/
public function getBody()
{
return $this->body;
}
}
任何人都可以解释我的错误(互联网对我没有多大帮助)..为什么我会收到此错误?
P.S。:我正在使用Symfony 2.4.1和PHP 5.4.20
答案 0 :(得分:5)
我认为这一行(Item
):
/**
* @ORM\DiscriminatorMap({"ITEM"="Item", "ARTICLE"="Article" "IMAGE"="Media"})
*/
应该是:
/**
* @ORM\DiscriminatorMap({"ITEM"="Item", "ARTICLE"="Article", "IMAGE"="Media"})
* ^
*/
我不太确定,但可能是鉴别器地图需要完全合格的类名:
/**
* @ORM\DiscriminatorMap({
* "ITEM"="Beachteam\BeachteamBundle\Entity\Item",
* "ARTICLE"="Beachteam\BeachteamBundle\Entity\Article",
* "IMAGE"="Beachteam\BeachteamBundle\Entity\Media"
* })
*/
接下来,您需要从$type
中移除属性Item
,因为type
已被用作鉴别列。
您可能还想使用控制台验证映射:
app/console doctrine:schema:validate
修复可能会报告的所有错误。
<强>更新强>
属性Beachteam \ BeachteamBundle \ Entity \ Item :: $ type不存在
这意味着代码中的某个地方$type
的(现在不存在的)属性Item
仍在使用中。你必须追踪到哪里。
->type
。app/cache
文件夹的内容并运行app/console cache:clear
。答案 1 :(得分:1)
我认为您在生成作为继承属性的doctrine时计划了Item :: $ type属性。但这也是由注释创建的:
@ORM\DiscriminatorColumn(name="type", type="string")
您拥有一个具有相同名称的表键和字段的一部分。尝试删除类属性(和getter,setter方法),然后更新模式
php app/console doctrine:schema:update --force
在此更改之后,您的课程就像我的盒子上的魅力一样
祝你好运!
