Laravel从嵌套关系2中获取数组

Question

I need to get pathtags and add it to a variable so I can replace it with ['XML','PHP','CSS3'].

$Paths = Path::with([
    'ProgrammingField',
    'pathtags' => function ($q) {
        $q->with(['Tasks' => function ($q) {
            $q->has('tasktags', '=', 2)
                ->orderBy('id', 'ASC')
                ->whereDoesntHave('tasktags',
                    function ($query)  {
                        $query->whereNotIn('name', ['XML','PHP','CSS3']);
                    }
                )
                ->with('tasktags')->orderBy('id', 'DESC');
        }]);
    }
])->whereIn('id', $pathId)->get();

Tried

$query->whereNotIn('name', $q->pathtags);
