对一个教义的@OneToMany ArrayCollection进行排序 [英] Sort a doctrine's @OneToMany ArrayCollection

问题描述

我的问题与这个问题接近，但并不完全适合与我的.

My question is close to this one, but does not exactly fit with mine.

我在实体中拥有此列:

/**
 * @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;

我想按SubjectTag.position中定义的位置动态排序标签.

I want to dynamically order my tags by a position, defined in SubjectTag.position.

推荐答案

尝试将doctrine2 ORM功能用于

Try using the doctrine2 ORM functionality for Ordering To-Many Associations like this:

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