Magento2 Perlu membangun Kotak dengan koleksi tabel banyak menggunakan Komponen UI

Dimulai dengan membangun modul khusus, ia memiliki fitur untuk menampilkan tampilan GRID yang perlu digabungkan dengan beberapa tabel dalam koleksi dan membuatnya pada GRID dan filter.

Saya telah menggunakan Komponen UI dari magento2 tetapi saya tidak dapat menyelesaikan tugas bergabung dengan beberapa tabel dalam koleksi dan menyiapkan tampilan kisi.

Siapa pun dapat membantu saya dalam hal ini.

Saya membuat kisi admin yang menggabungkan dua tabel khusus. Anda tidak dapat melakukan ini dengan menggunakan jenis virtual di.xml, jadi Anda harus mengikuti langkah-langkah ini dan memperbarui

dll / di.xml,

Model / Resource / Modulename / Collection.php tambahkan bergabung dalam file ini,

Model / Sumber Daya / Modulename / Grid / Collection.php,

DI dll / di.xml Anda

Semoga itu bisa membantu.

Bergabunglah 2 tabel

Di Anda Vendor\Module\Model\ResourceModel\ModelName\Grid\Collection, tambahkan fungsi _initSelect () seperti di bawah ini

protected function _initSelect()
{
    parent::_initSelect();

    $this->getSelect()->joinLeft(
        ['secondTable' => $this->getTable('admin_user')], //2nd table name by which you want to join
        'main_table.user_id= secondTable.user_id', // common column which available in both table 
        '*' // '*' define that you want all column of 2nd table. if you want some particular column then you can define as ['column1','column2']
    );
}

Bergabunglah dengan 3 tabel dan Lainnya

Gunakan thirdTable , thirdTable untuk bergabung dengan lebih banyak tabel seperti di bawah ini:

protected function _initSelect()
{
    parent::_initSelect();

    $this->getSelect()->joinLeft(
        ['secondTable' => $this->getTable('admin_user')],
        'main_table.user_id = secondTable.user_id',
        ['username']
    )->joinLeft(
        ['thirdTable' => $this->getTable('catalog_product_entity')],
        'main_table.product_id = thirdTable.entity_id',
        ['sku']
    );//use fourthTable, fifthTable to join more tables
}

Contoh

File app/code/SAdmin/Cart/etc/di.xml.

Nama item adalah nama data_source yang digunakan dalam Komponen UI Anda.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

Harap perhatikan memperluas Magento\Framework\View\Element\UiComponent\DataProvider\SearchResultdan mengatur parameter $mainTabledan $resourceModel.

namespace SAdmin\Cart\Model\ResourceModel\Quote\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 Magento\Framework\View\Element\UiComponent\DataProvider\SearchResult;
use Psr\Log\LoggerInterface as Logger;

class Collection extends SearchResult
{
    public function __construct(
        EntityFactory $entityFactory, Logger $logger, FetchStrategy $fetchStrategy, EventManager $eventManager,
        $mainTable = 'quote',
        $resourceModel = 'Magento\Quote\Model\ResourceModel\Quote',
        $identifierName = null, $connectionName = null
    )
    {
        parent::__construct($entityFactory, $logger, $fetchStrategy, $eventManager, $mainTable, $resourceModel, $identifierName, $connectionName);
    }

    public function _initSelect()
    {
        parent::_initSelect();
        return $this->getSelect()->joinLeft(
            ['secondTable' => $this->getTable('customer_group')], //2nd table name by which you want to join
            'main_table.customer_group_id= secondTable.customer_group_id', // common column which available in both table
            ['customer_group_code']// '*' define that you want all column of 2nd table. if you want some particular column then you can define as ['column1','column2']
        );
    }
}
