casasController.php 第 51 行中的 Laravel 5.2 FatalErrorException

Question

我需要你的帮助。我正在 Laravel5.2 中构建一个 webApp。这是我无法解决的问题... casasController.php 第 51 行中的 FatalErrorException ;我真的不知道该怎么做……在命名空间中正确声明了对象，并且一旦验证就保存了!

这是我的 Controller :

    <?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;
use App\Oggetto;
use App\Categoria;
use DB;
use Session;

class casasController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $oggetti = DB::table('casas')->get();
        $categoriasSelect = DB::table('categorias')->get();
        return view('pages.casa')->with('categoriasSelect', $categoriasSelect)->with('oggetti', $oggetti);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $this->validate($request, [
            'nome' => 'required',
            'categoria' => 'required',
            'descrizione' => 'required'
            ]);

        $oggetto = new Oggetto;
        $oggetto->nome = $request->nome;
        $oggetto->categoria = $request->categoria;
        $oggetto->descrizione = $request->descrizione;
        $status = $request->nome;

        $oggetto->save();

        Session::flash('success', 'Il tuo oggetto per la casa è stato salvato con successo!');

        return view('pages.casa')->with('oggetto', $oggetto);
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        //
    }
}

这些是我的路线:

Route::get('/', 'pagesController@index');

Route::group(array('prefix' => 'luogo'), function(){
    Route::get('casa',['as' => 'opzione1', 'uses' => 'casasController@index']);
    Route::get('parco',['as' => 'opzione2', function(){
        return view('pages.parco');
    }]);
    Route::get('stazione',['as' => 'opzione3', function(){
        return view('pages.stazione');
    }]);
});
Route::post('nome', ['as' => 'nomeInput', 'uses' => 'pagesController@form']);
//Authentication Routes(login) -->built in
Route::get('auth/login', ['as' => 'login', 'uses' => 'Auth\AuthController@getLogin']);
Route::post('auth/login', ['as' => 'loginPost', 'uses' => 'Auth\AuthController@postLogin']);
Route::get('auth/logout', [ 'as' => 'logout', 'uses' => 'Auth\AuthController@getLogout']);

//Registration Routes(new users) -->built in
Route::get('auth/register', ['as' => 'register', 'uses' => 'Auth\AuthController@getRegister']);
Route::post('auth/register', 'Auth\AuthController@postRegister');

Route::post('categoria', ['as' => 'categ', 'uses' => 'categoriasController@newCat']);
Route::resource('oggetto/{status?}', 'casasController', ['except' => ['show']]);

这是我的观点:

@extends('main')

@section('content')

    <h1 class="text-center">Benvenuto a Casa</h1>
    <h3 class="text-center"><a href="" id="link_formOggetto"> Aggiungi un oggetto</a></h3>
        <div class="row">
            <div class="col-md-8 col-md-offset-2">
                @if(count($errors) > 0)
                    @foreach($errors->all() as $error)
                        <div class="alert alert-danger">{{$error}}</div>
                    @endforeach
                @elseif(Session::has('success'))
                    <div class="alert alert-success">{{Session::get('success')}}</div>
                @endif
                <table class="table table-striped">
                    <thead>
                        <tr>

                        </tr>
                    </thead>
                    <tbody>
                        @foreach($oggetti as $oggetto)
                        <tr>

好的，您没有 Oggetto 模型，因此您需要先创建它。

也改变这个:

$oggetto = new Oggetto;

对此:

$oggetto = new Oggetto();
