在Magento 2的销售订单网格中正确添加新列

如何解决在Magento 2的销售订单网格中正确添加新列

我创建了一个模块，在销售网格中添加2列，shipping_information和跟踪号。 这些列会出现，但是当我尝试在管理订单页面（例如973）中按订单ID进行过滤时，出现此错误

main.CRITICAL: Item (Magento\Framework\View\Element\UiComponent\DataProvider\Document\Interceptor) with the same ID "6245" already exists. {"exception":"[object] (Exception(code: 0): Item (Magento\\Framework\\View\\Element\\UiComponent\\DataProvider\\Document\\Interceptor) with the same ID \"6245\" already exists. at /home/xxxx/public_html/vendor/magento/framework/Data/Collection.php:404)"} 

也是这个错误

Integrity constraint violation: 1052 Column 'created_at' in order clause is ambiguous

但是当我尝试使用另一个ID时，错误消失了

在Vendor / Module / Model / ResourceModel / Order / Grid / Collection.php中

namespace Wetag\AdditionalOrderFields\Model\ResourceModel\Order\Grid;

use Magento\Framework\Data\Collection\Db\FetchStrategyInterface as FetchStrategy;
use Magento\Framework\Data\Collection\EntityFactoryInterface as EntityFactory;
use Magento\Framework\Event\ManagerInterface as EventManager;

use Psr\Log\LoggerInterface as Logger;

/**

 */
class Collection extends OriginalCollection
{
    protected $helper;

    public function __construct(
        EntityFactory $entityFactory,Logger $logger,FetchStrategy $fetchStrategy,EventManager $eventManager,$mainTable = 'sales_order_grid',$resourceModel = \Magento\Sales\Model\ResourceModel\Order::class
    )
    {
        parent::__construct($entityFactory,$logger,$fetchStrategy,$eventManager,$mainTable,$resourceModel);
    }

protected function _renderFiltersBefore()
{
    $joinTable = $this->getTable('sales_order');
    $joinTable_track = $this->getTable('sales_shipment_track');
    
    
    $this->getSelect()->joinLeft($joinTable,'main_table.entity_id = sales_order.entity_id',['shipping_information'])->distinct();
    $this->getSelect()->joinLeft($joinTable_track,'sales_order.entity_id = sales_shipment_track.order_id',['track_number'])->distinct();
    parent::_renderFiltersBefore();
}
protected function _initSelect()  {

    $this->addFilterToMap('increment_id','main_table.increment_id');
    $this->addFilterToMap('status','main_table.status');
    parent::_initSelect();
  
   return $this; 

}
}

        </column>

</listing>

我喜欢在order_sales_grid表中使用shipping_information字段，没有左联接就没有得到它，我喜欢选择没有联接的情况

解决方法

我通过按entity_id -> group（'main_table.entity_id'）分组解决了该问题，以删除重复的行并删除LeftJoin到Sales_order表，因为sales_order_grid表中已经存在shipping_information

protected function _renderFiltersBefore()
{
    $joinTable_track = $this->getTable('sales_shipment_track');
    $this->getSelect()->joinLeft($joinTable_track,'main_table.entity_id = sales_shipment_track.order_id',['track_number'])->group('main_table.entity_id');
parent::_renderFiltersBefore();
}
