在数据透视表中附加数据时，时间戳记未更新 [英] Timestamps are not updating while attaching data in pivot table

问题描述

我正在使用以下attach语句在数据透视表中创建一行.

I'm creating a row in pivot table using the following attach statement.

$music = Music::find(1);
$music->users()->attach(1);

这将在数据透视表中插入一行，但是，它没有更新时间戳.时间戳记仍为00:00:00

This inserting a row in pivot table but, It is not updating the timestamp. The timestamp remains 0000-00-00 00:00:00

是否有任何方法可以更新数据透视表中的时间戳. ?

Is there any way to update the timestamps in pivot table. ?

预先感谢

推荐答案

如果您想自动维护数据透视表 created_at和updated_at时间戳，请使用withTimestamps() 关系定义的方法.

If you want your pivot table to have automatically maintained created_at and updated_at timestamps, use the withTimestamps() method on the relationship definition.

return $this->belongsToMany('Role')->withTimestamps();
