Laravel 5.2 не может обновить запись

Question

Я не могу обновить свою запись.

Мой контроллер

public function add() 
{ 
    return view('cars.add'); 
} 

public function edit($id) 
{ 
    $car = Cars::whereId($id)->firstOrFail(); 
    return view('cars.edit', compact('car')); 
} 

public function store(CarFormRequest $request) 
{ 
    $car = new Cars(array(
     'name' => $request->get('name'), 
     'color_id' => $request->get('color') 
    )); 

    $car->save(); 
    $car->position_id = $car->id; 
    $car->save(); 

    session()->flash('status', 'Successfully Added a Car!'); 
    return view('cars.add'); 
} 

public function update($id, CarFormRequest $request) 
{ 
    $car = car::whereId($id)->firstOrFail(); 
    $car->name = $request->get('name'); 
    $car->color_id = $request->get('color'); 
    if($request->get('status') != null) { 
     $car->status = 0; 
    } else { 
     $car->status = 1; 
    } 
    $car->save(); 
    return redirect(action('CarController@edit', $car->id))->with('status', 'The ticket '.$id.' has been updated!'); 

} 

мои маршруты:

Route::get('/', 'PagesController@home'); 
Route::get('/about', 'PagesController@about'); 
Route::get('/contact', 'PagesController@contact'); 
Route::get('/cars', 'CarsController@index'); 
Route::get('/cars/edit/{id?}', 'CarsController@edit'); 
Route::post('/cars/edit/{id?}', 'CarsController@update'); 
Route::get('/cars/add', 'CarsController@add'); 
Route::post('/cars/add', 'CarsController@store'); 

вот мое мнение:

<div class="container col-md-8 col-md-offset-2"> 
<div class="well well bs-component"> 
    <form class="form-horizontal" method="post"> 
     <input type="hidden" name="_token" value="{!! csrf_token() !!}">

Answer 1

$id переменная, где должен быть массив, и вы должны указать базу данных колонка тоже. Это должно быть как - {?} Идентификатор

public function edit($id) 
{ 
    $car = Cars::whereId('id', [$id])->firstOrFail(); 
    return view('cars.edit', compact('car')); 
} 

Изменить все вхождения в

$car = car::whereId($id)->firstOrFail();
