我正在嘗試訪問在 url 中傳遞的變量以傳遞給新表單。我目前有一個客戶端表，它與 Lifepolicy 表有 hasMany 關系。在為人壽政策構建創建表單時，我不斷收到未定義的變量。（使用 Laravel 5.8）這是我的代碼：class Lifepolicy extends Model{    protected $guarded = [        'id'    ];    public function client()    {        return $this->belongsTo(Client::class);    }    public function addLifepolicy($lifepolicy)    {        $this->lifepolicies()->create($lifepolicy);    }}class Client extends Model{    protected $guarded = [        'id'    ];    public function Lifepolicy()    {        return $this->hasMany(Lifepolicy::class);    }}     public function create(Request $request, Client $client)    {        return view('lifepolicies.create', $client);    }    Route::resource('/client/{client}/lifepolicy', 'ClientLifepolicyController');這是拋出錯誤的部分：<form role="form" method="POST" action="/client/{{ $client->id }}/lifepolicy">
