Question

我怀疑是否有嵌入式表格。我有一个“属性”实体，它有2个字段“id”和“name”和“Amenities”实体，它有2个字段“id”和“value”（id = 1，value = wifi，id = 2，value = water ，id = 3，value = food）。我创建了这两个实体，但现在我想将“Properties”和“Amenities”的id保存到一个单独的3rd表中。所以，我创建了第三个实体“Properties_Amenities”和它的表“properties_amenities”。我创建了“一对多”关系，如下所示。我想通过点击“属性表”中的“添加设施”按钮将“设施”嵌入“属性”.I我不确定在实体文件中放置“addAmenities（）”和“removeAmenities（）”函数的位置。以下是3个实体： -

Properties.php

<?php

namespace EpitaEvents\FormBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * Properties
 *
 * @ORM\Table(name="properties")
 * @ORM\Entity
 */
class Properties
{
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="name", type="string", length=100)
 */
private $name;

/**
 * @ORM\OneToMany(targetEntity="Properties_Amenities", mappedBy="properties",cascade={"persist"})
 **/
private $properties_amenities1;

public function __construct() {
    $this->properties_amenities1 = new ArrayCollection();
}


/**
 * Get id 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set name
 */
public function setName($name)
{
    $this->name = $name;

    return $this;
}

/**
 * Get name
 */
public function getName()
{
    return $this->name;
}

/**
 * Get properties_amenities1  
 */
public function getProperties_Amenities1() 
{
    return $this->properties_amenities1;
}

/**
 * Set properties_amenities1  
 *  
 */
public function setProperties_Amenities1($properties_amenities1)
{
    $this->properties_amenities1 = $properties_amenities1;
    return $this;
}

/**
 * Add Amenities
 * 
 * @return Properties
 */
public function addAmenities(\EpitaEvents\FormBundle\Entity\Properties_Amenities $amenities) 
{
    $amenities->setProperties($this);
    $this->amenities[] = $amenities;
    return $this;
}

/**
 * Remove Amenities
 * 
 */
public function removeAmenities(\EpitaEvents\FormBundle\Entity\Properties_Amenities $amenities) {
    $this->amenities->removeElement($amenities);
}
}

Amenities.php

<?php

namespace EpitaEvents\FormBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;

/**
 * Amenities
 *
 * @ORM\Table(name="amenities")
 * @ORM\Entity
 */
class Amenities
{
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var string
 *
 * @ORM\Column(name="value", type="string", length=100)
 */
private $value;

/**
 * @ORM\OneToMany(targetEntity="Properties_Amenities", mappedBy="amenities")
 **/
private $properties_amenities2;

public function __construct() {
    $this->properties_amenities2 = new ArrayCollection();
}

/**
 * Get id
 *
 * @return integer 
 */
public function getId()
{
    return $this->id;
}

/**
 * Set value
 *
 * @param string $value
 * @return Amenities
 */
public function setValue($value)
{
    $this->value = $value;

    return $this;
}

/**
 * Get value
 *
 * @return string 
 */
public function getValue()
{
    return $this->value;
}

/**
 * Set Properties
 * 
 */
public function setProperties_Amenities2($properties_amenities2) 
{
    $this->properties_amenities2 = $properties_amenities2;
    return $this;
}

/**
 * Get Properties
 * 
 * @return EpitaEvents\FormBundle\Entity\Properties
 */
public function getProperties_Amenities2() 
{
    return $this->properties_amenities2;
}
}

（也应将__construct（）放入上述2个文件或“Properties_Amenities.php”（下）中） Properties_Amenities.php

<?php

namespace EpitaEvents\FormBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Properties_Amenities
 *
 * @ORM\Table(name="properties_amenities")
 * @ORM\Entity
 */

class Properties_Amenities
{
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @ORM\ManyToOne(targetEntity="Properties", inversedBy="properties_amenities1")
 * @ORM\JoinColumn(name="properties_id", referencedColumnName="id")
 **/
private $properties;

/**
 * @ORM\ManyToOne(targetEntity="Amenities", inversedBy="properties_amenities2")
 * @ORM\JoinColumn(name="amenities_id", referencedColumnName="id")
 **/
private $amenities; 

function getId() {
    return $this->id;
}

function getProperties() {
    return $this->properties;
}

function getAmenities() {
    return $this->amenities;
}

function setProperties($properties) {
    $this->properties = $properties;
}

function setAmenities($amenities) {
    $this->amenities = $amenities;
}
}

任何人都可以建议在哪里放置“addAmenities（）”和“removeAmenities（）”函数，因为我想在“分离”中保存“Properties.php”和“Amenities.php”的“id” ，第三个“实体和表??
