保存新的Eloquent模型时，Laravel 5.3 - 500内部错误

Question

尝试创建模型Apartment的新实例时，我得到500 (Internal Server Error)。我有其他/create/路线用于创建我的模型的新实例，它们正常工作，并且它们设置与ApartmentController@create相同，但由于某些奇怪的原因，它不会工作

ApartmentController@create

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function create()
{
    $addresses = Address::all();
    return view('address/create')->with('addresses', $addresses);
}

ApartmentController@store

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    $address = new Address();
    $this->authorize('create', $address);

    $validator = Validator::make($request->all(), [
        'building_number' => 'required|integer',
        'street' => 'required|string',
    ]);

    if ($validator->fails()) {
        return redirect('addresses/create')
            ->withErrors($validator)
            ->withInput();
    }

    $address->building_number = $request->building_number;
    $address->street = $request->street;

    $address->save();

    return redirect('addresses/create');
}

View apartment/create

公寓模型的公寓表

我尝试在save()方法上捕获异常，但没有捕获任何内容，我仍然被重定向到/apartments而没有任何Laravel错误只是Chroms 500错误页面。

这就是我尝试使用dwightwatson/validating捕获错误的方法：

try{
        $apartment = new Apartment();

        $apartment->apartment_number = $request->apartment_number;
        $apartment->size = $request->size;
        $apartment->living_area_size = $request->living_area_size;
        $apartment->suitable_for = $request->suitable_for;
        $apartment->furnished = $request->furnished;
        $apartment->balcony_or_terrace = $request->balcony_or_terrace;
        $apartment->floor = $request->floor;
        $apartment->description = $request->description;
        $apartment->address_id = $request->address_id;

        $apartment->saveOrFail();

    } catch (ValidationException $e) {
        $errors = $e->getErrors();

        return redirect()->route('apartments.create')
        ->withErrors($errors)
        ->withInput();
    }

首先，如果您还没有，请Download Fiddler。将其启动，然后再次触发存储方法。提琴手应该告诉你很多关于你的要求和回应的信息：

在左侧，您有一个请求列表，在右侧，您有统计信息和检查员。在检查员标签下，您会看到 WebView 。单击它，您将看到Laravel生成的错误。

至于它可能失败的原因，请检查引用是否正确包含在内。 e.g：

use App\Address;
