相关疑难解决方法(0)

我想了解基于相关实体订购Doctrine Collection的最佳方法.在这种情况下,无法使用@orderBy注释.

我在互联网上找到了5个解决方案.

1)向AbstractEntity添加方法(根据Ian Belter /sf/answers/1552846921/)

/**
 * This method will change the order of elements within a Collection based on the given method.
 * It preserves array keys to avoid any direct access issues but will order the elements
 * within the array so that iteration will be done in the requested order.
 *
 * @param string $property
 * @param array  $calledMethods
 *
 * @return $this
 * @throws \InvalidArgumentException
 */
public function orderCollection($property, $calledMethods = array())
{
    /** …

我的问题接近这个问题,但并不完全适合我的问题.

我在一个实体中有这个专栏:

/**
 * @var ArrayCollection[SubjectTag]
 *
 * @ORM\OneToMany(targetEntity="SubjectTag", mappedBy="subject")
 * @Assert\Count(max = 10, maxMessage = "You can't create more than 10 tags.")
 * @Assert\Valid()
 */
protected $subjectTags;

我想通过定义的位置动态地对我的标签进行排序SubjectTag.position.
