Timestamps are not updating while attaching data i

问题:

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

$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

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

Thanks in advance,

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();
