从表中的hasMany循环数据时，我得到一个错误“试图获取财产上的非对象‘perbaikan’”

Question

我得到一个错误，试图让房地产非对象的“perbaikan”。请帮我解决我的问题。

My Perbaikan model
public function tagihan()
    {
        return $this->belongsTo('App\Tagihan', 'id_tagihan');
    }

My Tagihan model
  public function perbaikan()
    {
        return $this->hasMany('App\Perbaikan');
    }

My controller
public function report(Tagihan $tagihan)
{
   return view('tagihan.report', compact('tagihan'));
}

My view blade
<tbody>
   <?php $no = 0;?>
   @foreach ($tagihan as $data)
   @foreach ($data->perbaikan as $row)
   <?php $no++ ;?>
     <tr>
         <td>{{ $no }}</td>
         <td>{{ $row -> nomor_dokumen }}</td>
         <td>{{ $row -> kulkas -> nomor_asset  }}</td>
         <td>{{ $row -> tipepekerjaan -> kode_tipe_pekerjaan }}</td>
         <td>{{ $row -> tanggal_perbaikan }}</td>
     </tr>
   @endforeach
   @endforeach
 </tbody>

            $table->timestamps();

    }

我试图从表中的hasMany得到的所有数据，它工作正常，但我不想从表中的所有数据。我只希望基于来自属于关联表中的ID检索数据

我得到消息，“试图获得财产非对象的“perbaikan”错误

Answer 1

您是通过$tagihan循环，但是这是没有必要的

更改：

   @foreach ($tagihan as $data)
   @foreach ($data->perbaikan as $row)

至：

   @foreach ($tagihan->perbaikan as $row)

并取出@endforeach之一
