17-3 修改考試的儲存動作

1. 修改控制器\專案\app\Http\Controllers\TestController.php

   public function store(Request $request)
   {
       $content = collect($request->ans)->toJson();
       $score   = 0;
       foreach ($request->ans as $topic_id => $ans) {
           $topic = Topic::find($topic_id);
           $score += ($topic->ans == $ans) ? 20 : 0;
       }
   
       $class_info = session('pref/language');
       $test       = Test::create([
           'content' => $content,
           'user_id' => $request->user_id,
           'exam_id' => $request->exam_id,
           'score'   => $score,
           'grade'   => substr($class_info, 0, 2),
           'class'   => substr($class_info, 2, 2),
           'num'     => substr($class_info, 4, 2),
       ]);
       return redirect()->route('test.show', $test->id);
   }

    

2. 修改考試的模型\專案\app\Test.php，主要是修改$fillable新增加入的欄位

   <?php
   
   namespace App;
   
   use Illuminate\Database\Eloquent\Model;
   
   class Test extends Model
   {
       protected $fillable = [
           'content', 'user_id', 'exam_id', 'score','grade','class','num',
       ];
   
       public function exam()
       {
           return $this->belongsTo('App\Exam');
       }
   
       public function user()
       {
           return $this->belongsTo('App\User');
       }
   }
