默认的排序与注解主义模型

本文介绍了默认的排序与注解主义模型的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 在问题在默认排序属性教义型号一个 .yml 建议将定义一个默认的排序为一个集合值的关联。In question at Default sort attribute for Doctrine Model a .yml is suggested to define a default sorting for a collection-valued association.我想有我的模型由一个默认的排序进账，像下面这样：I would like to have my models fetched by a default sorting, like following:Foo: columns: ... options: orderBy: bar DESC什么是诠释这相当于基于YAML的设置的？What is the annotation equivalent of this YAML-based setup?推荐答案 编辑：这是不可能的默认值。从仓库提取的实体是由提供的排序标准提取： This is not possible with defaults. Entities fetched from repositories are fetched by the provided sorting criteria:$entities = $entityRepository->findBy(array(), array('field' => 'ASC'));这， DQL 和标准API 是获取当前方法与给定的排序标准的实体。This, DQL and the Criteria API are the current ways of fetching entities with a given sorting criteria.在什么问题默认排序属性教义型号是大约是集合值关联的排序，这无关与库实体直接抓取。What the question at " Default sort attribute for Doctrine Model " is about is the sorting of collection-valued associations, which has nothing to do with direct fetching of entities from repositories.对于那些协会，默认注释当量排序属性为原​​则型号是以下（原来的答案）：For those associations, the annotation-equivalent of " Default sort attribute for Doctrine Model " is following (original answer):作为的教义2 ORM 官方说明文档，注释为A HREF =htt​​ps://github.com/doctrine/doctrine2/blob/2.3集合值关联默认的排序条件 @OrderBy（{场=ASC，otherField=DESC}） 。As of the official annotations documentation for Doctrine 2 ORM, the annotation for default sorting conditions of collection-valued associations @OrderBy({"field" = "ASC", "otherField" = "DESC"}).下面是你将如何使用它：Here's how you would use it:/** * @ORM\OneToMany(targetEntity="Users") * @ORM\OrderBy({"username" = "ASC"}) */protected $users; 这篇关于默认的排序与注解主义模型的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
