Laravel update parent of parent updated_at timestamp

I am trying to update a parent of a parents updated_at timestamp when the child model is updated. I can updated the parent model using the following code inside the child model

protected $touches = ['post']

but for example if I also wanted to update the user who made the posts updated_at timestamp how would I do this?

I was hoping I could just add the following code to the Post.php model

protected $touches = ['user']

but this doesn't seem to work, the user model timestamp only gets updated if the Post record is updated.

Perhaps something like Model Events could help you?...

Post.php

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    /**
     * The "booted" method of the model.
     *
     * @return void
     */
    protected static function booted()
    {
        static::updated(function ($post) {
            $post->user->touch();
        });
    }
}

This is assuming that your Post has a User relationship defined.

Here we are listening for the updated event on the Post. When that event is triggered, the associated User is touched.
