我有一个“shipment”模型，其中有很多“shipment_details”模型记录。

public function shipment_details(){
      return $this->hasMany('App\Shipment_Detail', 'shipmentID','id');
}

当我创建“shipment”记录时，最初创建“shipment_details”没有问题。

当我想更新“shipment”记录并且最终需要在下面添加额外的“shipment_detail”记录时，我的问题就出现了。

目前我的“shipment_details”的 html 是来自 Blade 的:

<tbody>
    @foreach($shipment_details as $sd)
    <tr style="height:40px">
        <td style="width:8%;text-align:center;">{{Form::text('shipment_details['.$sd->id.'][piecesNumber]', $sd->pieces_number, array('class' => 'form-control','placeholder'=>'No. Pieces','required','id'=>'piecesNumber'))}}
        </td>
        <td style="width:16%;text-align:center;">
            {!! Form::select('shipment_details['.$sd->id.'][piecesType]', $piecetypes, $sd->pieces_type, ['id' => 'pieces_type', 'class' => 'form-control full-width','required']) !!}    
        </td>
        <td>
            {!! Form::select('shipment_details['.$sd->id.'][rateType]', $ratetypes, $sd->rate_type, ['id' => 'rateType', 'class' => 'form-control full-width','required']) !!}
        </td>
        <td style="width:16.5%;text-align:center;">
            {{Form::text('shipment_details['.$sd->id.'][weight]', $sd->weight, array('class' => 'form-control','placeholder'=>'Weight','required','id'=>'weight'))}}    
        </td>
        <td style="width:16.5%;text-align:center;">
            {{Form::select('shipment_details['.$sd->id.'][hazmat]',array(
                                    '0'=>'No',
                                    '1'=>'Yes',
                                ), $sd->hazmat, array('class' => 'form-control','id'=>'hazmat'))}}   
        </td>
        <td style="width:16.5%;text-align:center;">
                            {{Form::text('shipment_details['.$sd->id.'][description]', $sd->description, array('class' => 'form-control','placeholder'=>'Description','required','id'=>'description'))}} 
        </td>
        <td style="width:16.5%;text-align:center;">
            {{Form::text('shipment_details['.$sd->id.'][charge]', $sd->charge, array('class' => 'form-control','placeholder'=>'Charge','required','id'=>'charge'))}} 
        </td>
        <td><button type="button" name="add" id="add" class="btn btn-success">Add More</button></td>
    </tr>

    @endforeach
</tbody>

添加更多按钮是指这个脚本:

<script>
 $(document).ready(function(){  
      var i=1;  
      $('#add').click(function(){  
            i++;  
           $('#freight_bill_items').append('<tr id="row'+i+'"> <td style="width:8%;text-align:center;">{{Form::text('shipment_details[piecesNumber][]', null, array('class' => 'form-control','placeholder'=>'No. Pieces','required','id'=>'piecesNumber'))}}</td><td style="width:16%;text-align:center;">{!! Form::select('shipment_details[piecesType][]', $piecetypes, 'null', ['id' => 'pieces_type', 'class' => 'form-control full-width','required']) !!} </td><td>{!! Form::select('shipment_details[rateType][]', $ratetypes, null, ['id' => 'rateType', 'class' => 'form-control full-width','required']) !!}</td><td style="width:16.5%;text-align:center;">{{Form::text('shipment_details[weight][]', null, array('class' => 'form-control','placeholder'=>'Weight','required','id'=>'weight'))}}</td><td style="width:16.5%;text-align:center;">{{Form::select('shipment_details[hazmat][]',array('No'=>'No','Yes'=>'Yes',), null, array('class' => 'form-control','id'=>'hazmat'))}}</td><td style="width:16.5%;text-align:center;">{{Form::text('shipment_details[description][]', null, array('class' => 'form-control','placeholder'=>'Description','required','id'=>'description'))}}</td><td style="width:16.5%;text-align:center;">{{Form::text('shipment_details[charge][]', null, array('class' => 'form-control','placeholder'=>'Charge','required','id'=>'charge'))}}</td><td><button type="button" name="remove" id="'+i+'" class="btn btn-danger btn_remove">X</button></td></tr>');   
      });  
      $(document).on('click', '.btn_remove', function(){  
           var button_id = $(this).attr("id");   
           $('#row'+button_id+'').remove();
           $( 'input[name^="shipment_details[charge][]"]' ).trigger( "change" );
      });

 });
</script>

然后在当前时刻，我的“shipment_details”通过 Controller 以下列方式“保存”:

    foreach ( $request->shipment_details as $id => $details ) {
        $shipdetail = Shipment_Detail::find($id);
        $shipdetail->pieces_type = $details['piecesType'];
        $shipdetail->pieces_number = $details['piecesNumber'];
        $shipdetail->rate_type = $details['rateType'];
        $shipdetail->weight = $details['weight'];
        $shipdetail->charge = $details['charge'];
        $shipdetail->description = $details['description'];
        $shipdetail->hazmat = $details['hazmat'];
        // Other info to update here
        $shipdetail->save();
    }

所以我的问题是，有没有办法增加“shipment_details”？它需要使用 updateOrCreate 之类的东西还是需要其他东西？

更新

这就是我的数组目前的发布方式，目前发布时出现错误 - undefined index :piecesType。目前，如果我更新当前的 shipment_detail，它工作正常，添加新的会产生问题。

shipment_details    

array:8 [▼
  13149 => array:7 [▼
    "piecesNumber" => "1"
    "piecesType" => "1"
    "rateType" => "1"
    "weight" => "12"
    "hazmat" => "0"
    "description" => "124"
    "charge" => "12.00"
  ]
  "piecesNumber" => array:1 [▼
    0 => "3"
  ]
  "piecesType" => array:1 [▼
    0 => "2"
  ]
  "rateType" => array:1 [▼
    0 => "2"
  ]
  "weight" => array:1 [▼
    0 => "1200"
  ]
  "hazmat" => array:1 [▼
    0 => "Yes"
  ]
  "description" => array:1 [▼
    0 => "desc2"
  ]
  "charge" => array:1 [▼
    0 => "40.00"
  ]
]

更新

ALEXEY 的装运 Controller

foreach ($request->shipment_details as $id => $details) {
            $shipdetail = Shipment_Detail::updateOrCreate(['id' => $id], [
            'pieces_type' => $details['piecesType'][0],
            'pieces_number' => $details['piecesNumber'][0],
            'rate_type' => $details['rateType'][0],
            'weight' => $details['weight'][0],
            'charge' => $details['charge'][0],
            'description' => $details['description'][0],
            'hazmat' => $details['hazmat'][0]
                ]);
        }

更新

更新为 dd($id, $details);

13149

array:7 [▼
  "piecesNumber" => "1"
  "piecesType" => "1"
  "rateType" => "1"
  "weight" => "12"
  "hazmat" => "0"
  "description" => "124"
  "charge" => "12.00"
]

但它不包括我试图通过此保存添加的最近添加的行。

最佳答案

您可以像这样使用 updateOrCreate():

foreach ($request->shipment_details as $id => $details) {
    $shipdetail = Shipment_Detail::updateOrCreate(['id' => $id], [
        'pieces_type' => $details['piecesType'],
        'pieces_number' => $details['piecesNumber'],
        'rate_type' => $details['rateType'],
        'weight' => $details['weight'],
        'charge' => $details['charge'],
        'description' => $details['description'],
        'hazmat' => $details['hazmat']
    ]);
}
