Laravel：数据未出现在视图中

Question

大家好，我的数据不会显示在视图中

下面是我的控制器代码，我很难解决此问题

public function prediksi()
        {
            $collection = array();
            $title = "Data Prediksi Sentimen";
            $testing_data = DataTesting::count();
            $klasifikasi = DataTesting::with(['data_crawling','klasifikasi'])->get();
            foreach($klasifikasi as $class){
                $prediksi = Klasifikasi::with(['sentimen'])->where('id_testing',$class->id_testing)->first();
                $hasil = Hasil::where('id_testing',$class->id_testing)->get();
                $aktual = Sentimen::where('id_sentimen', $class->data_crawling->id_sentimen)->first();
                if($prediksi && isset($prediksi->kategori)){
                      $collection[] = [
                    'id_testing' => $class->id_testing,
                    'username' => $class->data_crawling->username,
                    'tweet' => $class->data_crawling->tweet,
                    'kategori' => $aktual->kategori,
                    'prediksi' => $prediksi->sentimen->kategori,
                ];
                 $hasil_data[$class->id_testing][] = $hasil;
                }
            }

            return view('visualisasi.prediksi', compact(['title','collection','testing_data','hasil_data']));
        }

下面是我的代码视图

<?php $no=1; ?>
                                        @foreach($collection as $key)
                                        <tr>
                                            @foreach($hasil_data[$key['id_testing']] as $hasil){
                                            dd($hasil);
                                            <td align="center">{{$no++ ."."}}</td>
                                            <td align="center">{{$key['username']}}</td>
                                            <td align="left"><a data-toggle="modal"
                                                    href="#Detail_{{$key['id_testing']}}"> {{$key['tweet']}}</a></td>
                                            <td align="center">{{$key['kategori']}}</td>
                                            <td align="center">{{$key['prediksi']}}</td>
                                        }
                                            @endforeach

                                        </tr>
                                        @endforeach

我的控制器或我的观点有问题吗？请帮助我找到解决方案]]

您正在视图（第5行）上使用dd()，这将结束脚本的执行。删除它，并将其放在控制器上的dd()之前，以转储给定的var，并在将数据传递到视图之前检查数据：
