Timestamps are not updating while attaching data in pivot table
提问by Sriraman
I'm creating a row in pivot table using the following attach statement.
我正在使用以下附加语句在数据透视表中创建一行。
$music = Music::find(1);
$music->users()->attach(1);
This inserting a row in pivot table but, It is not updating the timestamp. The timestamp remains 0000-00-00 00:00:00
这会在数据透视表中插入一行，但不会更新时间戳。时间戳保持 0000-00-00 00:00:00
Is there any way to update the timestamps in pivot table. ?
有什么方法可以更新数据透视表中的时间戳。?
Thanks in advance,
提前致谢，

If you want your pivot table to have automatically maintained created_at and updated_at timestamps, use the
withTimestamps()method on the relationship definition.
如果您希望数据透视表自动维护 created_at 和 updated_at 时间戳，请使用
withTimestamps()关系定义上的方法。
return $this->belongsToMany('Role')->withTimestamps();
