Question

好的...我觉得这个问题很愚蠢但是......

我有一个包含以下实体的实体：

供应商：

/**
 * @ORM\OneToMany(targetEntity="SRC\Bundle\MarketingBundle\Entity\Ad", mappedBy="vendor", cascade={"all"})
 *
 * @var Collection|Ad[]
 */
protected $ads;

/**
 * Returns all vendor ads.
 *
 * @return Collection|Ad[]
 */
public function getAds()
{
    return $this->ads;
}

/**
 * Sets all vendor ads.
 *
 * @param Collection $ads
 */
public function setAds(Collection $ads)
{
die("SET ADS. DIE! DIE!");
    $this->ads = $ads;

    return $this;
}

/**
 * Adds vendor ad.
 *
 * @param Ad $ad
 */
public function addAd(Ad $ad)
{
    if (!$this->hasAd($ad)) {
        $ad->setVendor($this);
        $this->ads->add($ad);
    }

    return $this;
}

/**
 * Removes vendor ad.
 *
 * @param Ad $ad
 */
public function removeAd(Ad $ad)
{
    if ($this->hasAd($ad)) {
        $this->ads->removeElement($ad);
        $ad->setVendor(null);
    }

    return $this;
}

/**
 * Checks whether vendor has given ad.
 *
 * @param Ad $ad
 *
 * @return Boolean
 */
public function hasAd(Ad $ad)
{
    return $this->ads->contains($ad);
}

/**
 * @ORM\ManyToOne(targetEntity="SRC\Bundle\VendorBundle\Entity\Vendor", inversedBy="products", fetch="LAZY")
     * @ORM\JoinColumn(name="vendor_id", referencedColumnName="id", nullable=true)
 * @var Vendor
 */
protected $vendor;

/**
 * Get vendor.
 *
 * @return Vendor
 */
public function getVendor(){
    return $this->vendor;
}

/**
 * Set vendor.
 *
 * @param Vendor $vendor
 */
public function setVendor(Vendor $vendor){
    $this->vendor = $vendor;

    return $this;
}

当我更新广告＆＃34; setAds（）＆＃34;时，供应商CRUD中存在问题。永远不会被调用，因为你可以在那里看到die（），它永远不会被执行。我做错了什么???

首选“添加”方法到“设置”

public function addAd(\SRC\Bundle\MarketingBundle\Entity\Ad $ad)
{
    if(!$this->ads->contains($ad)) {
        $this->ads[] = $ad;
    }
    return $this;
}

public function removeAd(\SRC\Bundle\MarketingBundle\Entity\Ad $ad)
{
    $this->ads->removeElement($ad);
}

public function getAds()
{
    return $this->ads;
}

我假设您可能在Ad类中调用 setVendor 方法来执行关系，同步双方执行以下操作：

public function setVendor(Vendor $vendor){
    $this->vendor = $vendor;
    $vendor->addAd($this);
    return $this;
}

您还应该在Vendor构造函数中初始化ArrayCollection：

public __construct()
{
    $this->ads = new \Doctrine\Common\Collections\ArrayCollection();
}
