Laravel與關係中的問題

Question

當用戶不是管理員時遇到問題。目標是僅獲取屬於該用戶的請求，但是當我使用where子句時，我會從數據庫中獲取所有請求。 它應該只能得到所有請求管理員。

謝謝你的幫助！

public function index(){ 
    $status = request('status', -1); 
    $paper_size = request('paper_size', -1); 

    if (auth()->user()->isAdmin()) { 
     $requests = Request:: 
      where('paper_size', $paper_size)->orWhereRaw($paper_size. ' = -1')-> 
      where('status', $status)->orWhereRaw($status. ' = -1')-> 


      orderBy(
       request('orderby') ? request('orderby') : 'created_at', 
       request('order') ? request('order') : 'DESC' 
      )->paginate(10); 

     $departments = Departament::All(); 


     return view('Requests.index', compact('requests', 'departments')); 
    } 

    $requests = auth()->user()->requests()-> 
     where('status', $status)->orWhereRaw($status. ' = -1')-> 
     where('paper_size', $paper_size)->orWhereRaw($paper_size. ' = -1')-> 
     orderBy(
      request('orderby') ? request('orderby') : 'created_at', 
      request('order') ? request('order') : 'DESC' 
     )->paginate(10); 

     return view('Requests.index', compact('requests')); 
} 

UPDATE：

我已經可以列出所有的用戶請求，但是狀態過濾器不起作用。

PS：過濾器 「PAPER_SIZE」 正按預期

由於整個社會，特別是對@Sandeesh

public function index(){ 
    request('status') == -1 || request('status') == null ? 
     $statusExists = false : $statusExists = true; 
    $status = request('status'); 

    request('paper_size') == -1 || request('paper_size') == null ? 
     $paper_sizeExists = false : $paper_sizeExists = true; 
    $paper_size = request('paper_size'); 

    $is_admin = auth()->user()->isAdmin(); 

    $requests = Request::when($statusExists, function ($query) use ($status) { 
     return $query->where('status', $status); 
    }) 
     ->when($paper_sizeExists, function ($query) use ($paper_size) { 
      return $query->where('paper_size', $paper_size); 
     }) 
     ->when(!$is_admin, function ($query) { 
      return $query->where('owner_id', auth()->id()); 
     }) 
     ->orderBy(request('orderby', 'created_at'), request('order', 'desc')) 
     ->paginate(10); 

    if (!$is_admin) { 
     return view('Requests.index', compact('requests')); 
    } 

    $departments = Departament::all(); 

    return view('Requests.index', compact('requests', 'departments')); 
} 

Answer 1

包裝你where和​​條件共同爲一列。或者使用when而不是使用-1 = -1申請的解決方法。我也爲你重構了代碼。

public function index() 
{ 
    $status = request('status'); 
    $paper_size = request('paper_size'); 

    $is_admin = auth()->user()->isAdmin(); 

    $requests = Request::when(!is_null($status), function ($query) use ($status) { 
      return $query->where('status', $status); 
     }) 
     ->when(!is_null($paper_size), function ($query) use ($paper_size) { 
      return $query->where('paper_size', $paper_size); 
     }) 
     ->when(!$is_admin, function ($query) { 
      return $query->where('owner_id', auth()->id()); 
     }) 
     ->orderBy(request('orderby', 'created_at'), request('order', 'desc')) 
     ->paginate(10); 

    if (!$is_admin) { 
     return view('Requests.index', compact('requests')); 
    } 

    $departments = Departament::all(); 

    return view('Requests.index', compact('requests', 'departments')); 
} 

Answer 2

您將需要得到$user_id = Auth::id然後更新第二個查詢以獲得where user_id = $user_id語句（我不確定哪些表屬於該用戶）。

Answer 3

嘗試用：

$requests = Request::with('User') 
    ->where('user_id',\Auth::user()->user_id) 
    ->where('status', $status) 
    ->orWhereRaw($status. ' = -1') 
    ->where('paper_size', $paper_size) 
    ->orWhereRaw($paper_size. ' = -1') 
    ->orderBy(request('orderby') ? request('orderby') : 'created_at', 
       request('order') ? request('order') : 'DESC')->paginate(10);
