如评论中所述，one-to-one关联涉及您不能将两个Post与Media相关联。{/ p>

要允许此操作，请更改您的关联：

/**
 * @ORM\OneToOne(targetEntity="FLY\BookingsBundle\Entity\Media", cascade={"persist","remove"})
 * @ORM\JoinColumn(nullable=true)
 */
private $image;

致：

/**
 * @ORM\ManyToOne(targetEntity="FLY\BookingsBundle\Entity\Media", cascade={"persist","remove"})
 * @ORM\JoinColumn(nullable=true)
 */
private $image;
