卡在集合数组上

我正在获取特定数组。但无法在刀片中循环

这是我的控制器：

public function appliedJob($id)
{

   $apllied = AplliedJob::with('user','job')->find($id);


    return view('dashboardviews.page.apllied-job',compact('apllied'));
 }

这是我的模特

   class AplliedJob extends Model
   {

   use Notifiable;
   protected $fillable = [
    'name', 'email', 'message','aplied_cv',
   ];
   protected  $table='appllied_jobs';
   //protected $primaryKey = 'user_id';

   protected $primaryKey = 'user_id';

   public function user()
   {
    return $this->belongsTo('App\User','user_id');
   }
   public function job()
   {

   return $this->belongsTo('App\Job','job_id');
   }

   }

这是我要获取的数组，我想访问关联＃[作业]，但它引发错误

我已经尝试过了，但是却给出了例外情况

     @foreach($apllied as $aplil)

     {{$aplil->job->jb_name}}

     @endforeach

这是我遇到的错误，无法弄清楚我在做什么错

     ErrorException (E_ERROR)
     Trying to get property 'job' of non-object (View: 
    D:\xampp\htdocs\locojobs\resources\views\dashboardviews\page\apllied- 
    job.blade.php)

Answer 1

find()返回一个模型，因此您需要执行以下操作：

     {{$apllied ->job->jb_name}} //Remove the loop

或使用get()代替find()

Answer 2

我从这段代码中得到的结果是，每个AplliedJob实例都有一个Job。因此，正如@Anas Bakro所说，您需要从代码中删除@foreach。如果要构建其他体系结构，请写下您的表格。

Answer 3

尝试使用get（）或paginate（）代替find（），因为find（）返回单个值。

尝试以下代码，

public function appliedJob($id)
{

   $apllied = AplliedJob::with('user')->with('job')->get();

    return view('dashboardviews.page.apllied-job',compact('apllied'));
}

不能循环通过laravel集合数组
