If you know how many levels maximum could be nested you can use Eager Loading. Let's say if maximum depth is 3 levels you can do:

$model->with('parent.parent.parent');

You can also use recursion instead of loop.

public function getParentsAttribute()
{
    if (!$this->parent) {
        return collect([]);
    }

    return collect($this->parent->parents)->push($this->parent);
}

In case you want to add the first one object too (self) the full call will be:

$model->parents->push($model)->reverse->implode('attr_name', '/');

Which you can also wrap into attribute

public function getPathAttribute() {
    return $model->parents->push($model)->reverse->implode('attr_name', '/');
}

And call like $model->path;
