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

问题描述

我的问题很接近这个，但并不完全适合和我的.

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

我在实体中有此列:

/**
 * @var ArrayCollection[SubjectTag]
 *
 * @ORMOneToMany(targetEntity="SubjectTag", mappedBy="subject")
 * @AssertCount(max = 10, maxMessage = "You can't create more than 10 tags.")
 * @AssertValid()
 */
protected $subjectTags;

我想按在SubjectTag.position 中定义的位置对我的标签进行动态排序.

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

推荐答案

尝试使用 doctrine2 ORM 功能 对多关联排序 像这样:

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

/**
 * @var ArrayCollection[SubjectTag]
 *
 * @ORMOneToMany(targetEntity="SubjectTag", mappedBy="subject")
 * @ORMOrderBy({"position" = "ASC"})
 * @AssertCount(max = 10, maxMessage = "You can't create more than 10 tags.")
 * @AssertValid()
 */
protected $subjectTags;
