如何在数据透视表中使用额外的列 table

Question

我需要制作一个自定义字段，就像清单一样，但在 table 中，还有第二个字段 "order"。
这是我的：

模型 1：条件与关系 "belongsToMany"
模型 2：子服务

这两个模型与tableproducts_service有两个foreign_keys加列"order"

的关系

我无法理解的是：
怎么用背包保存额外的信息。

我知道我可以使用这样的东西：

$user->roles()->updateExistingPivot($roleId, $attributes);

但是我应该把它放在哪里呢？

这是我的代码：

class Condition extends Model
{
  use CrudTrait;
  use Searchable;

  public function relService()
  {
    //dd($this->belongsToMany(SubService::class, 'conditions_service')->withPivot('weight')->withTimestamps());
            return $this->belongsToMany(SubService::class, 'conditions_service')->withPivot('weight')->withTimestamps();
  }
}

class SubService extends Model
{
  use Searchable;
  use CrudTrait;

  public function conditions()
  {
    return $this->belongsToMany(Condition::class, 'conditions_service')->withPivot('weight')->withTimestamps();
  }
}

这是我的自定义字段类型：

<!-- select2 -->
<div @include('crud::inc.field_wrapper_attributes') >
    <label>{!! $field['label'] !!}</label>
    @include('crud::inc.field_translatable_icon')
    <?php $entity_model = $crud->getModel(); ?>

    <div class="row">

                    @if ($crud->details_row)
                        <th></th> <!-- expand/minimize button column -->
                    @endif

                    {{-- Table columns --}}
                    <th>Seleziona</th>
                    <th>Ordine</th>

                                    <input type="checkbox"
                                           name="{{ $field['name'] }}[]"
                                           value="{{ $connected_entity_entry->id }}"

                </tbody>

我找到了解决方案，感谢 dense-team 的拉取请求 (https://github.com/Laravel-Backpack/CRUD/pull/351)

这是我更新的代码：

CrudController:

$this->crud->addField([
        'label'     => 'Servizi legati',
        'type'      => 'checklist_ordered',
        'name'      => 'relService',
        'entity'    => 'relService',
        'attribute' => 'title',
        'model'     => "App\Models\SubService",
        'pivot'     => true,
        'pivotFields' => [
            'weight' => 'Ordinamento',
        ],
    ], 'update/create/both');

这是我的自定义字段类型：

<!-- select2 -->
<div @include('crud::inc.field_wrapper_attributes') >

    @include('crud::inc.field_translatable_icon')

        <?php $entity_model = $crud->getModel();

        $pivot_entries = null;
        if (isset($entry)) {
            $pivot_entries = $entry->{$field['entity']}->keyBy(function ($item) {
                return $item->getKey();
            });
        }
        ?>
