Update parent data when the child data is updated in Laravel

Use the $touches property to update the parent timestamp when a child is updated.

Did you know you can update the parent model timestamp when a child is updated?

If you have a “belongsTo” or “belongsToMany” relationship you can define a “$touches” property to do this

class Comment extends Model
{
    protected $touches = ['post'];
    
    public function post()
    {
        return $this->belongs To (Post::class);
    }
}
