Laravel 5，無法通過請求方法插入不存在

Question

這就是我想要沒有任何成功的事情：

在welcome.blade我有一些板和所產生的子卡（隨機一個foreach用戶）在哪裏你可以點擊子板和去這樣/ subboardOne。我得到這個在我的routes.php文件

Route::get('/{subboaName}', 'ThreadController@index'); 
Route::post('/{subboaName}', 'ThreadController@store'); 

，那麼你可以通過形式寄出對這段扣板線程，但因爲我真的不知道怎麼laravel知道他在哪裏，形式是這樣的：

<form class="form col-md-12 center-block" role="form" method="POST" action="/{{$subboardcoll->id}}"> 

這個$ subboardcoll-> ID來自控制器，它通過指數函數發送收集：

public function index($subboard) 
{ 
    $subboardcoll = Subboard::where('subboaName', $subboard)->first(); 
    $threads = Thread::where('subboaId', $subboardcoll->id) 
      ->orderBy('created_at', 'desc') 
      ->get(); 
    return view('threads.thread', compact('threads', 'subboardcoll')); 
} 

然後我試圖把我的形式和存儲線程autoinserti納克subboardId但laravel不承認扣板方法：

public function store(Request $request) 
    { 
     $this->validate($request, [ 
      'comentario' => 'required|max:2000', 
      //'g-recaptcha-response' => 'required|recaptcha', 
      //'imagen' => 'required', 
     ]); 

     $request->subboards()->threads()->create([ 
      'thrName' => $request->nombre, 
      'thrComment' => $request->comentario, 
      'thrImg' => $request->imagen, 
      'thrSubject' => $request->tema, 
     ]); 

     return redirect()->back(); 

    } 

，給我這個erorr：

BadMethodCallException in Macroable.php line 81: Method subboards does not exist. 

你們helpme能知道爲什麼嗎？還有更好的形式來做我想要做的？上laravel IM新手，感謝

編輯：

Thread.php

public function subboard() 
{ 
    return $this->belongsTo(Subboard::class, 'subboaId'); 
} 

Subboard.php

public function thread() 
{ 
    return $this->hasMany(Thread::class); 
}

方法扣板不請求對象存在。考慮這樣做

public function store($id, Request $request) 
{ 
    $this->validate($request, [ 
     'comentario' => 'required|max:2000', 
     //'g-recaptcha-response' => 'required|recaptcha', 
     //'imagen' => 'required', 
    ]); 

    Subboard::find($id)->threads()->create([ 
     'thrName' => $request->nombre, 
     'thrComment' => $request->comentario, 
     'thrImg' => $request->imagen, 
     'thrSubject' => $request->tema, 
    ]); 

    //Alternative query statement 
    Subboard::where('id', $id)->first()->threads()->create([..... 

    return redirect()->back(); 

}
