Laravel在create和store方法中返回未知错误

我有一个问题与我的项目，我尝试写方法保存记录到数据库。我创建了控制器ProductsController，其中我添加了方法:

public function create(){
        $articles = Article::lists('article_name', 'id');
        $categories = Category::lists('category_name', 'id');
        $date = Carbon::now();
        $minDate = Carbon::minValue($date);
        return view('pages.createproduct', compact('articles', 'categories', 'date', 'minDate'));
    }
    public function store(CreateProductRequest $request){
        dd($request->article_name);
        $product = new Product($request->all());
        Auth::user()->products()->save($product);
        return redirect('warehouse');
    }

接下来我创建了文件createproduct.blade.php:

{!! Form::open(['url' => 'warehouse/create', 'class' => 'form-horizontal']) !!}
        {!! Form::select('article_name[]', $articles, NULL, ['class' => 'form-control']) !!}<br />
        {!! Form::select('category_name[]', $categories, NULL, ['class' => 'form-control']) !!}<br />
        {!! Form::text('sn', null, ['class' => 'form-control', 'placeholder' => 'Podaj serial...']) !!}<br />
        {!! Form::number('quantity', null, ['class' => 'form-control', 'min' => '1', 'placeholder' => 'Podaj ilość...']) !!}<br />
        {!! Form::date('warranty', $date, ['class' => 'form-control', $minDate]) !!}<br />
        {!! Form::submit('Dodaj', ['class' => 'btn btn-default']); !!}
{!! Form::close() !!}

我的routes.php文件是这样的:

Route::get('/contact', 'PagesController@contact');
Route::resource('/addarticle', 'ArticlesController');
Route::resource('/addcategory', 'CategoriesController');
Route::resource('/warehouse', 'ProductsController');
Route::auth();
Route::get('/home', 'HomeController@index');

当我当我想保存记录到数据库Laravel返回一个错误:
