我正在创建一个在多个商店（即亚马逊、eBay 等）具有产品及其多个价格的表单，以比较价格并向消费者提供最低价格。
我在构建这种类型的表单时遇到了问题。我无法使用背包的表字段将数据存储在数据库中，所以我需要帮助。
CRUD 控制器：
<?php
namespace App\Http\Controllers\Admin;
use Backpack\CRUD\app\Http\Controllers\CrudController;
// VALIDATION: change the requests to match your own file names if you need form validation
use App\Http\Requests\MenRequest as StoreRequest;
use App\Http\Requests\MenRequest as UpdateRequest;
class MenCrudController extends CrudController
{
public function setup()
{
$this->crud->setModel('App\Models\Men');
$this->crud->setRoute(config('backpack.base.route_prefix') . '/men');
$this->crud->setEntityNameStrings('men', 'mens');
//$this->crud->setFromDb();
// ------ CRUD FIELDS
// $this->crud->addField($options, 'update/create/both');
// $this->crud->addFields($array_of_arrays, 'update/create/both');
$this->crud->addFields([
[ // Table
'name' => 'mens',
'label' => 'Options',
'type' => 'table',
'entity_singular' => 'option', // used on the "Add X" button
'columns' => [
'name' => 'Name',
'price'=>'Price',
],
'max' => 5, // maximum rows allowed in the table
'min' => 0 // minimum rows allowed in the table
],
]);
// $this->crud->removeField('name', 'update/create/both');
// $this->crud->removeFields($array_of_names, 'update/create/both');
// ------ CRUD COLUMNS
// $this->crud->addColumn(); // add a single column, at the end of the stack
// $this->crud->addColumns(); // add multiple columns, at the end of the stack
$this->crud->addColumns(
[
[
'label' =>'Product Name',
'name' =>'name',
],
]);
// $this->crud->removeColumn('column_name'); // remove a column from the stack
// $this->crud->removeColumns(['column_name_1', 'column_name_2']); // remove an array of columns from the stack
// $this->crud->setColumnDetails('column_name', ['attribute' => 'value']); // adjusts the properties of the passed in column (by name)
// $this->crud->setColumnsDetails(['column_1', 'column_2'], ['attribute' => 'value']);
// ------ CRUD BUTTONS
// possible positions: 'beginning' and 'end'; defaults to 'beginning' for the 'line' stack, 'end' for the others;
// $this->crud->addButton($stack, $name, $type, $content, $position); // add a button; possible types are: view, model_function
// $this->crud->addButtonFromModelFunction($stack, $name, $model_function_name, $position); // add a button whose HTML is returned by a method in the CRUD model
// $this->crud->addButtonFromView($stack, $name, $view, $position); // add a button whose HTML is in a view placed at resources\views\vendor\backpack\crud\buttons
// $this->crud->removeButton($name);
// $this->crud->removeButtonFromStack($name, $stack);
// $this->crud->removeAllButtons();
// $this->crud->removeAllButtonsFromStack('line');
// ------ CRUD ACCESS
// $this->crud->allowAccess(['list', 'create', 'update', 'reorder', 'delete']);
// $this->crud->denyAccess(['list', 'create', 'update', 'reorder', 'delete']);
// ------ CRUD REORDER
// $this->crud->enableReorder('label_name', MAX_TREE_LEVEL);
// NOTE: you also need to do allow access to the right users: $this->crud->allowAccess('reorder');
// ------ CRUD DETAILS ROW
// $this->crud->enableDetailsRow();
// NOTE: you also need to do allow access to the right users: $this->crud->allowAccess('details_row');
// NOTE: you also need to do overwrite the showDetailsRow($id) method in your EntityCrudController to show whatever you'd like in the details row OR overwrite the views/backpack/crud/details_row.blade.php
// ------ REVISIONS
// You also need to use \Venturecraft\Revisionable\RevisionableTrait;
// Please check out: https://laravel-backpack.readme.io/docs/crud#revisions
// $this->crud->allowAccess('revisions');
// ------ AJAX TABLE VIEW
// Please note the drawbacks of this though:
// - 1-n and n-n columns are not searchable
// - date and datetime columns won't be sortable anymore
// $this->crud->enableAjaxTable();
// ------ DATATABLE EXPORT BUTTONS
// Show export to PDF, CSV, XLS and Print buttons on the table view.
// Does not work well with AJAX datatables.
// $this->crud->enableExportButtons();
// ------ ADVANCED QUERIES
// $this->crud->addClause('active');
// $this->crud->addClause('type', 'car');
// $this->crud->addClause('where', 'name', '==', 'car');
// $this->crud->addClause('whereName', 'car');
// $this->crud->addClause('whereHas', 'posts', function($query) {
// $query->activePosts();
// });
// $this->crud->addClause('withoutGlobalScopes');
// $this->crud->addClause('withoutGlobalScope', VisibleScope::class);
// $this->crud->with(); // eager load relationships
// $this->crud->orderBy();
// $this->crud->groupBy();
// $this->crud->limit();
}
public function store(StoreRequest $request)

// your additional operations before save here
