Comment utiliser une colonne supplémentaire dans un tableau croisé dynamique

Question

Je dois créer un champ personnalisé comme une liste de contrôle, mais dans une table et avec un deuxième champ "ordre".
C'est ce que j'ai:

• Modèle 1: Conditions avec les relations "belongsToMany"
• Modèle 2: Subservices

Ces deux modèles sont en relations avec la table products_service qui a les deux foreign_keys plus la colonne "order"

Ce que je ne peux pas comprendre est:
Comment pourrait enregistrer les informations supplémentaires avec sac à dos.

Je sais que je peux utiliser quelque chose comme ceci:

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

mais où dois-je le mettre?

Voici mon code:

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(); 
    } 
} 

Voici mon type de champ personnalisé:

<!-- 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"> 
     <div class="col-sm-12"> 
      <table id="crudTable" class="table table-bordered table-striped display"> 
       <thead> 
       <tr> 
        @if ($crud->details_row) 
         <th></th> <!-- expand/minimize button column --> 
        @endif 

        {{-- Table columns --}} 
        <th>Seleziona</th> 
        <th>Ordine</th> 
        {{--<th>Ordine <i class="fa fa-arrow-up" aria-hidden="true"></i></th> 
        <th>Ordine <i class="fa fa-arrow-down" aria-hidden="true"></i></th>--}} 
        {{--$tst = $connected_entity_entry->relService->whereIn('id', $connected_entity_entry->id)--}} 
       </tr> 
       </thead> 
       <tbody> 
       @foreach ($field['model']::all() as $connected_entity_entry) {{--var_dump((empty($connected_entity_entry->conditions->toArray())?"puppa":(empty($connected_entity_entry->conditions->whereIn('id', $connected_entity_entry->id)->toArray())?"puppa uguale":$connected_entity_entry->conditions->whereIn('id', $connected_entity_entry->id)))) --}} 
       {{-- dump($connected_entity_entry->getPriority($connected_entity_entry->id)) --}} 
       <tr> 
        <th scope="row"> 
         <div class="col-sm-4"> 
          <div class="checkbox"> 
           <label> 
            <input type="checkbox" 
              name="{{ $field['name'] }}[]" 
              value="{{ $connected_entity_entry->id }}" 

              @if((old($field["name"]) && in_array($connected_entity_entry->id, old($field["name"]))) || (isset($field['value']) && in_array($connected_entity_entry->id, $field['value']->pluck('id', 'id')->toArray()))) 
              checked="checked" 
              @endif > {!! $connected_entity_entry->{$field['attribute']} !!} 
           </label> 
          </div> 
         </div> 
        </th> 
        <td>{{--@include('crud::fields.number')--}} 

        </td> 
       </tr> 
       @endforeach 
       </tbody> 
      </table> 
     </div> 

     {{-- HINT --}} 
     @if (isset($field['hint'])) 
      <p class="help-block">{!! $field['hint'] !!}</p> 
     @endif 
    </div> 
</div> 

Merci pour votre aide! Dave

J'ai trouvé une solution grâce équipe dense avec sa demande de traction (https://github.com/Laravel-Backpack/CRUD/pull/351)

Voici mon code mis à jour:

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'); 

Voici mon type de champ personnalisé:

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

     $pivot_entries = null; 
     if (isset($entry)) { 
      $pivot_entries = $entry->{$field['entity']}->keyBy(function ($item) { 
       return $item->getKey(); 
      }); 
     } 
     ?> 
     <div class="row"> 
      <div class="col-sm-12"> 
       <table id="crudTable" class="table table-bordered table-striped display"> 
        <thead> 
        <tr> 
         @if ($crud->details_row) 
          <th></th> <!-- expand/minimize button column --> 
         @endif 

         {{-- Table columns --}} 
         <th>Seleziona</th> 
         @foreach($field['pivotFields'] as $pivot_chunk) 
          <th>{{$pivot_chunk}}</th> 
         @endforeach

               checked="checked" 
               @endif > {!! $connected_entity_entry->{$field['attribute']} !!}

            <?php 
            $pivot_attr = null; 
            if ($pivot_entries) { 
             if ($pivot_entries->has($connected_entity_entry->getKey())) { 
              $pivot  = $pivot_entries->get($connected_entity_entry->getKey())->pivot; 
              $pivot_attr = $pivot->getAttribute($pivot_field); 
             } 
            } 
            ?> 
            <input type="number" 
              name="{!! $pivot_field !!}[{{ $connected_entity_entry->getKey() }}]" 
              value="{{ $pivot_attr }}" @include('crud::inc.field_attributes') /> 
           @endforeach 
          @endforeach 
         </td> 
        </tr>
