如何在Laravel(7)中保存多态可变形模型的附加/附加列? [英] How to save additional/extra columns of the polymorphic morphable model in Laravel (7)?

问题描述

从Laravel docs网站获取多对多多态关系样本.

Take a many-to-many polymorphic relationship sample from the Laravel docs website.

posts
    id - integer
    name - string

videos
    id - integer
    name - string

tags
    id - integer
    name - string

taggables
    tag_id - integer
    taggable_id - integer
    taggable_type - string
    extra_column_a - string
    extra_column_b - integer

在创建带有标签的帖子/视频时或在创建带有帖子/视频的标签时，如何在 extra_column_a 和 extra_column_b 列中插入数据?

How to insert data into the extra_column_a and extra_column_b column when creating a post/video with tag or when creating a tag with post/video?

当 taggables 表具有额外的列时，我是否需要为其创建模型类?

Do I need to create a model class for the taggables table when it has extra columns?

推荐答案

也许是这样的.Arr中的第二个参数

Maybe something like this. Second parametr in arr

$video->tags()->attach($t, ['extra_column_a'=>'custstring','extra_column_b'=>'asd']);
