问题描述
我有三个实体：
FeatureValue.php
FeatureValue.php
<?php
namespace Webmuch\ProductBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* @ORM\Entity
*/
class FeatureValue
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length="100")
*/
protected $name;
/**
* @ORM\OneToMany(targetEntity="FeatureType", mappedBy="name")
*/
private $featuretype;
public function __construct()
{
$this->featuretype = new \Doctrine\Common\Collections\ArrayCollection();
}
FeatureType.php
FeatureType.php
<?php
namespace Webmuch\ProductBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Webmuch\ProductBundle\Entity\FeatureValue;
/**
* @ORM\Entity
*/
class FeatureType
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
protected $title;
/**
* @ORM\ManyToOne(targetEntity="FeatureValue", inversedBy="featuretype",cascade={"persist"})
* @ORM\JoinColumn(name="feature_value_id", referencedColumnName="id")
*/
protected $name;
public function __construct()
{
$this->name = new \Doctrine\Common\Collections\ArrayCollection();
}
Product.php
Product.php
<?php
namespace Webmuch\ProductBundle\Entity;
use Gedmo\Mapping\Annotation as Gedmo;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection as ArrayCollection;
/**
* @ORM\Entity
* @ORM\Table()
* @ORM\HasLifecycleCallbacks
*/
class Product
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\ManyToMany(targetEntity="Store")
*/
protected $store;
/**
* @ORM\ManyToMany(targetEntity="Webmuch\CategoryBundle\Entity\Category")
*/
protected $category;
/**
* @Gedmo\Sluggable
* @ORM\Column(type="string", length=255)
*/
protected $title;
/**
* @Gedmo\Slug(updatable=false, unique=true)
* @ORM\Column(type="string", length=255)
*/
protected $slug;
/**
* @ORM\Column(type="integer")
*/
protected $quantity;
/**
* @ORM\Column(type="boolean")
*/
protected $active;
/**
* @ORM\Column(type="text", length="4000", nullable="true")
*/
protected $preview;
/**
* @ORM\ManyToMany(targetEntity="FeatureType")
* @ORM\JoinColumn(name="feature_type_id", referencedColumnName="id")
*/
protected $features;
public function __toString()
{
return $this->getTitle();
}
}
我的问题是当我添加FeatureType中的FeatureValue然后显示错误类 Doctrine\Common\Collections\ArrayCollection不是有效的实体或映射的超类。
My problem is that when i add FeatureValue in FeatureType then show me error Class "Doctrine\Common\Collections\ArrayCollection is not a valid entity or mapped super class."
在我的项目中，我想要
假设在FeatureType中有两个属性Size和Colour。现在在FeatureType中有两个FeatueValue Small，Medium，Large，并且假设在FeatureType颜色中-给出了三个FeatureValue红色，绿色，黄色。
现在我想在我的产品实体中同时显示FeatureType及其FeatureValue。
suppose in FeatureType two property Size and Colour.Now in FeatureType Size- Three FeatueValue Small,Medium,Large have been given and also suppose in FeatureType Colour- Three FeatureValue Red,Green,Yello have been given.Now i want to show both the FeatureType along with their FeatureValue in my Product Entity.
所以任何人都告诉我该怎么做。很多，但没有成功。
So any one tell me how it can be done.I have tried a lot of but not succeed.
推荐答案
在 Webmuch\ProductBundle\Entity\FeatureType中： ：__ construct 您将 ArrayCollection 分配给 $ this-> name ，这是错误的，因为这是ToOne而不是ToMany。
In Webmuch\ProductBundle\Entity\FeatureType::__construct you assign an ArrayCollection to $this->name, this is wrong, as this is a ToOne and not a ToMany.
只需删除此行即可。
