问题选择了1行但更新了其他行主键Laravel 5.4中的所有行

Question

我必须从Eloquent代码中选择1个表1行

$ReceiveDetailSelected = ReceiveDetail::where([['subjectid', $subject],['psubid', $request->psubid],['id', $id]])->first();
return $ReceiveDetailSelected;

和结果

{"no":1,"id":1,"psubid":"1\/2017","pdetailid":"1","subjectid":"7","labid":"1","result":0,"path_file":"3","status":"pending","created_at":"2017-08-14 13:27:59","updated_at":"2017-08-14 15:19:39","deleted_at":null}

但在数据库中更新代码

中的所有行

$ReceiveDetailSelected = ReceiveDetail::where([['subjectid', $subject],['psubid', $request->psubid],['id', $id]])->first();
$ReceiveDetailSelected->status = 'pending';
$ReceiveDetailSelected->path_file = '4';
$ReceiveDetailSelected->save();
return $ReceiveDetailSelected;

功能中的完整代码

public function storenewwork($id,$subject,$product,Request $request)
  {
    $ReceiveDetailSelected = ReceiveDetail::where([['subjectid', $subject],['psubid', $request->psubid],['id', $id],['no', '1']]);
    $ReceiveDetailSelected->status = 'pending';
    $ReceiveDetailSelected->path_file = '4';
    $ReceiveDetailSelected->save();
    return $ReceiveDetailSelected;
  }

Answer 1

我通过添加protected $primaryKey = 'no';解决了我认为laravel已将pk设置为id。它将更新id= 1

中的所有行
