我有三个实体:
1.Feature
2.Value
3.产品
我在产品中获得价值而没有提及它的特征。我试图根据功能获得价值但是我无法做到。我不知道如何做到这一点?
/**
* @ORM\Table(name="feature")
* @ORM\Entity
*/
class Feature
{
/**
* @ORM\Id
* @ORM\Column(name="id", type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(name="name", type="string", length=50)
*/
protected $name;
/**
* @ORM\OneToMany(targetEntity="Feature", mappedBy="Feature")
**/
protected $value;
/**
* Constructor
*/
public function __construct()
{
$this->value = new \Doctrine\Common\Collections\ArrayCollection();
}
public function __toString()
{
return $this->getName();
}
}
/**
* @ORM\Table(name="value")
* @ORM\Entity
*/
class Value
{
/**
* @ORM\Id
* @ORM\Column(name="id", type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM\Column(name="name", type="string", length=50)
*/
protected $value;
/**
* @ORM\ManyToOne(targetEntity="Feature", inversedBy="value")
**/
protected $feature;
/**
* @ORM\ManyToMany(targetEntity="Product", mappedBy="value")
**/
private $product;
public function __construct()
{
$this->feature = new \Doctrine\Common\Collections\ArrayCollection();
}
public function __toString()
{
return $this->getValue();
}
}
/**
* @ORM\Entity
* @ORM\Table()
* @ORM\HasLifecycleCallbacks
*/
class Product
{
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @Gedmo\Translatable
* @ORM\Column(length=64)
*/
private $title;
/**
* @Gedmo\Slug(fields={"title"})
* @ORM\Column(length=64, unique=true)
*/
private $slug;
/**
* @ORM\Column(type="integer")
*/
protected $quantity;
/**
* @ORM\Column(type="boolean")
*/
protected $active;
/**
* @ORM\Column(type="datetime")
*/
protected $updated;
/**
* @ORM\Column(type="datetime")
*/
protected $created;
/**
* @ORM\ManyToMany(targetEntity="Value", inversedBy="product")
* @ORM\JoinTable(name="product_value")
**/
protected $value;
public function __construct()
{
$this->active = true;
$this->updated = new \DateTime();
$this->created = new \DateTime();
$this->value = new ArrayCollection();
}
public function __toString()
{
return $this->getTitle();
}
}
由于英语不足,我没有解释更多。
示例我想要的:
“我想根据产品选择产品的特征,例如尺寸和颜色,如红色,绿色和小,中等等。”
答案 0 :(得分:0)
总之,您需要构建自己的查询:
为Product创建一个存储库,并具有以下内容:
$qb = $this->getEntitymanager()->createQueryBuilder();
$qb
->select('p, f, v')
->from('YourBundleName:Product', 'p')
->leftJoin('p.value', 'v')
->innerJoin('v.feature', 'f');
return $qb->getQuery()->getResult();
然后对于每个产品,执行以下操作:
foreach ($products as $product) {
echo "Title: " . $product->getTitle() . "<br />";
echo "Features: <br />";
foreach ($product->getValue() as $value) {
echo $value->getFeature()->getName() . ": " . $value->getValue() . "<br />"
}
}
