Question

我得到的错误是：

在关联模型\ StoreBundle \ Entity \ campaign＃campaignOperatingSystems上找到Doctrine \ Common \ Collections \ ArrayCollection类型的实体，但期望model \ StoreBundle \ Entity \ campaignOS

这是campaignOS总结：

/**
 * model\StoreBundle\Entity\campaignOS
 * @ORM\Table(name="campaign_os")
 * @ORM\Entity
 */
class campaignOS extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('OS', 'entity', array(
                'class' => 'modelStoreBundle:listOS',
                'property' => 'OsName',
                'multiple' => 'true',
                'expanded' => 'true'
        ));
    }

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

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

    /**
     * @ORM\ManyToOne( targetEntity="campaign", inversedBy="campaignOperatingSystems" )
     * @ORM\JoinColumn( name="campaign_os_id", referencedColumnName="campaign_id" )
     */
    private $campaign;

    public function setCampaign( \model\StoreBundle\Entity\campaign $ourCampaign )
    {
        $this->$campaign = $ourCampaign;
    }

    public function getCampaign()
    {
        return $this->$campaign;
    }

    /**
     * @ORM\OneToOne( targetEntity="listOS" )
     * @ORM\JoinColumn( name="campaign_os_id", referencedColumnName="os_id" )
     */
    private $os;

    public function setOS( \model\StoreBundle\Entity\listOS $campaignOS )
    {
        $this->os = $campaignOS;
    }

    public function getOS()
    {
        return $this->os;
    }
}

这些方法的签名

public function addCampaignOperatingSystem(\model\StoreBundle\Entity\campaignOS $campaignOperatingSystems)
public function removeCampaignOperatingSystem(\model\StoreBundle\Entity\campaignOS $campaignOperatingSystems)

表示您希望在输入中输入 campaignOS 类型的单个对象，但是您要传递给其中一个ArrayCollection（campaignOS，我想）。

所以错误是签名或 - 可能 - 进入你的逻辑。

也许你想要像setCompaignOperationSystem这样的操作？

在关联（数组）上找到类型为Doctrine \ Common \ Collections \ ArrayCollection的实体，但期待（其他）
