试图获取非对象的属性“first_name”

Question

我试图获取与用户相关的数字化订单，但不幸的是，我面临一个错误。

请查看此错误：https://flareapp.io/share/VmeWJ47Q

控制器

public function index()
{
  $data=
     [
       'digitizings'=>Digitizing::with('user')->paginate(8)
     ];
  return view('front_end.profile.digitizing.digitizing_view_order',$data);
}

用户模型

class User extends Authenticatable
{
   use Notifiable;
   public function digitizing()
   {
      return $this->hasMany('App\Digitizing','user_id');
   }
                       
}

数字化模型

class Digitizing extends Model
{
  protected $fillable = ['id','order_name','height','width','urgent','image',
  'order_placement','required_format','order_fabric','instruction','user_id'];

protected $table ="digitizing_orders";

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

HTML视图

 @foreach($digitizings as  $key =>$digitizing)
    <tr>
        <td>DPO# {{$digitizing->id}}</td>
        <td>{{$digitizing->created_at}}</td>
        <td>{{$digitizing->order_name}}</td>
        <td>{{$digitizing->user->first_name}}</td>
        <td>{{$digitizing->user->email}}</td>
        <td>{{$digitizing->released_date ??  'processing'}}</td>
        <td><a href="">View</a>  
        </td>
    </tr>
 @endforeach

Answer 1

是否每个数字化条目都在数据库中设置了一个有效的user_id？试着在访问数据之前检查已加载的数据是否已设置。

Answer 2

尝试将数据发送到视图，如下所示：

public function index()
{
    $digitizings = Digitizing::with('user')->paginate(8);  
    return view('front_end.profile.digitizing.digitizing_view_order',$digitizings);
}
