如何为belongsToMany协会配置保存策略（追加）？ [英] How to configure saving strategy (append) for belongsToMany Association?

问题描述

我有一个belongsToMany关联，该关联删除了joinTable数据，因为我只是将新的连接放在要持久化的实体内。

所以我读了此处介绍以下两种策略：附加和替换。
替换是默认值。但是我还找不到如何将其设置为追加策略的方法？

i have a belongsToMany association which deletes joinTable data because i just put new connections inside the entity to be persited.
So i read here about the 2 strategys: append and replace. Replace is the default one. But i could not find out yet how to set it to append strategy?

推荐答案

您可以使用<$ c $定义belongsToMany关系c> saveStrategy 关键字，可以接受追加或替换。因此代码应类似于

You can define belongsToMany relation with saveStrategy keyword which accept either append or replace. So code should be like

$this->belongsToMany('Articles', [
            'joinTable' => 'articles_tags',
            'saveStrategy' => 'append'
        ]);
