Tampilkan gambar di admin grid di magento 2

Saya ingin menampilkan gambar di kisi admin salah satu modul saya.
Saya menggunakan sistem grid baru, yang dengan komponen ui.
Saya melihat bagaimana thumbnail ditambahkan di grid untuk produk, tapi itu agak berlebihan.
Entitas saya bukan EAV, adalah entitas tabel datar sederhana.
Saya mencoba menambahkan ini di file xml komponen ui saya

<column name="image">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/image</item>
            <item name="sortable" xsi:type="boolean">false</item>
            <item name="altField" xsi:type="string">name</item>
            <item name="has_preview" xsi:type="string">1</item>
            <item name="label" xsi:type="string" translate="true">Image</item>
        </item>
    </argument>
</column>

tetapi tampaknya tidak berpengaruh pada grid saya. tidak ada gambar (kolom db saya disebut gambar), tidak ada kesalahan, tidak ada apa-apa.
Dapatkah seseorang memandu saya menambahkan gambar ke grid menggunakan komponen ui?

Xui komponen ui Anda harus ditambahkan ini:

<column name="image" class="Your\Modulename\Ui\Component\Listing\Column\Thumbnail">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/thumbnail</item>
            <item name="sortable" xsi:type="boolean">false</item>
            <item name="altField" xsi:type="string">title</item>
            <item name="has_preview" xsi:type="string">1</item>
            <item name="label" xsi:type="string" translate="true">Thumbnail</item>
        </item>
    </argument>
</column>

..dan kemudian di \ Modulename \ Ui \ Component \ Listing \ Column \ Thumbnail.php Anda sesuatu yang mirip dengan ini:

<?php
namespace Your\Modulename\Ui\Component\Listing\Column;

use Magento\Catalog\Helper\Image;
use Magento\Framework\UrlInterface;
use Magento\Framework\View\Element\UiComponentFactory;
use Magento\Framework\View\Element\UiComponent\ContextInterface;
use Magento\Store\Model\StoreManagerInterface;
use Magento\Ui\Component\Listing\Columns\Column;

class Thumbnail extends Column
{
    const ALT_FIELD = 'title';

    /**
     * @var \Magento\Store\Model\StoreManagerInterface
     */
    protected $storeManager;

    /**
     * @param ContextInterface $context
     * @param UiComponentFactory $uiComponentFactory
     * @param Image $imageHelper
     * @param UrlInterface $urlBuilder
     * @param StoreManagerInterface $storeManager
     * @param array $components
     * @param array $data
     */
    public function __construct(
        ContextInterface $context,
        UiComponentFactory $uiComponentFactory,
        Image $imageHelper,
        UrlInterface $urlBuilder,
        StoreManagerInterface $storeManager,
        array $components = [],
        array $data = []
    ) {
        $this->storeManager = $storeManager;
        $this->imageHelper = $imageHelper;
        $this->urlBuilder = $urlBuilder;
        parent::__construct($context, $uiComponentFactory, $components, $data);
    }

    /**
     * Prepare Data Source
     *
     * @param array $dataSource
     * @return array
     */
    public function prepareDataSource(array $dataSource)
    {
        if(isset($dataSource['data']['items'])) {
            $fieldName = $this->getData('name');
            foreach($dataSource['data']['items'] as & $item) {
                $url = '';
                if($item[$fieldName] != '') {
                    $url = $this->storeManager->getStore()->getBaseUrl(
                        \Magento\Framework\UrlInterface::URL_TYPE_MEDIA
                    ).'pathtoyourimage/'.$item[$fieldName];
                }
                $item[$fieldName . '_src'] = $url;
                $item[$fieldName . '_alt'] = $this->getAlt($item) ?: '';
                $item[$fieldName . '_link'] = $this->urlBuilder->getUrl(
                    'your_module/yourentity/edit',
                    ['yourentity_id' => $item['yourentity_id']]
                );
                $item[$fieldName . '_orig_src'] = $url;
            }
        }

        return $dataSource;
    }

    /**
     * @param array $row
     *
     * @return null|string
     */
    protected function getAlt($row)
    {
        $altField = $this->getData('config/altField') ?: self::ALT_FIELD;
        return isset($row[$altField]) ? $row[$altField] : null;
    }
}

Saya harap itu membantu!

Dalam mendefinisikan grid.php Anda seperti di bawah ini

$this->addColumn(
    'image',
    array(
        'header' => __('Image'),
        'index' => 'image',
        'renderer'  => '\Vendorname\Modulename\Block\Adminhtml\Modulename\Grid\Renderer\Image',
    )
);

Buat di Image.phpbawah

\ Vendorname \ Modulename \ Block \ Adminhtml \ Modulename \ Grid \ Renderer \

dan rekatkan kode di bawah ini

namespace Vendorname\Modulename\Block\Adminhtml\Modulename\Grid\Renderer;

class Image extends \Magento\Backend\Block\Widget\Grid\Column\Renderer\AbstractRenderer
{
    protected $_storeManager;


    public function __construct(
        \Magento\Backend\Block\Context $context,
        \Magento\Store\Model\StoreManagerInterface $storeManager,      
        array $data = []
    ) {
        parent::__construct($context, $data);
        $this->_storeManager = $storeManager;        
    }


    public function render(\Magento\Framework\DataObject $row)
    {
        $img;
        $mediaDirectory = $this->_storeManager->getStore()->getBaseUrl(
           \Magento\Framework\UrlInterface::URL_TYPE_MEDIA
       );
        if($this->_getValue($row)!=''):
            $imageUrl = $mediaDirectory.$this->_getValue($row);
            $img='<img src="'.$imageUrl.'" width="100" height="100"/>';
        else:
            $img='<img src="'.$mediaDirectory.'Modulename/no-img.jpg'.'" width="100" height="100"/>';
        endif;
        return $img;
    }
}

Cukup tambahkan tag ini di ui_componentfile tata letak Anda

<column name="logo" class="NAMESPACE\MODULENAME\Ui\Component\Listing\Columns\Logo">
    <argument name="data" xsi:type="array">
        <item name="config" xsi:type="array">
            <item name="component" xsi:type="string">Magento_Ui/js/grid/columns/thumbnail</item>
            <!--<item name="add_field" xsi:type="boolean">true</item>-->
            <item name="sortable" xsi:type="boolean">false</item>
            <item name="altField" xsi:type="string">name</item>
            <item name="has_preview" xsi:type="string">1</item>
            <item name="label" xsi:type="string" translate="true">Brand Logo</item>
        </item>
    </argument>
</column>

dan buat file baru ini yang telah kami tetapkan di ui_componentkolom kami

<?php
namespace NAMESPACE\MODULENAME\Ui\Component\Listing\Columns;

use Magento\Framework\View\Element\UiComponentFactory;
use Magento\Framework\View\Element\UiComponent\ContextInterface;

class Logo extends \Magento\Ui\Component\Listing\Columns\Column
{
    const NAME = 'logo';

    const ALT_FIELD = 'name';

    protected $_storeManager;

    public function __construct(
        ContextInterface $context,
        UiComponentFactory $uiComponentFactory,        
        \Magento\Framework\UrlInterface $urlBuilder,
        array $components = [],
        array $data = [],
        \Magento\Store\Model\StoreManagerInterface $storeManager
    ) {        
        parent::__construct($context, $uiComponentFactory, $components, $data);
        $this->_storeManager = $storeManager;
        $this->urlBuilder = $urlBuilder;
    }

    /**
    * Prepare Data Source
    *
    * @param array $dataSource
    * @return array
    */
    public function prepareDataSource(array $dataSource)
    {
        if (isset($dataSource['data']['items'])) {
            $fieldName = $this->getData('name');
            foreach ($dataSource['data']['items'] as & $item) {
                $mediaRelativePath=$this->_storeManager->getStore()->getBaseUrl(\Magento\Framework\UrlInterface::URL_TYPE_MEDIA);
                $logoPath=$mediaRelativePath.$item['logo'];
                $item[$fieldName . '_src'] = $logoPath;
                $item[$fieldName . '_alt'] = $this->getAlt($item);
                $item[$fieldName . '_link'] = $this->urlBuilder->getUrl(
                    'brand/manage/edit',
                    ['brand_id' => $item['brand_id'], 'store' => $this->context->getRequestParam('store')]
                );
                $item[$fieldName . '_orig_src'] = $logoPath;

            }
        }

        return $dataSource;
    }

    /**
    * @param array $row
    *
    * @return null|string
    */
    protected function getAlt($row)
    {
        $altField = self::ALT_FIELD;
        return isset($row[$altField]) ? $row[$altField] : null;
    }
}

Dalam prepareDataSourcefungsinya Anda akan mendapatkan setiap objek kolom.

Semoga ini bisa membantu Anda.

Akhirnya, saya punya solusi untuk pertanyaan saya. Saya telah menambahkan kolom kotak dengan nama blok penyaji sebagai parameter.

$this->addColumn(
    'image',
    array(
        'header' => __('Image'),
        'index' => 'image',
        'renderer'  => '\YourVendor\YourModule\Block\Adminhtml\Inquiry\Grid\Renderer\Image',
    )
);

Kemudian saya telah menambahkan membuat blok renderer seperti di bawah ini:

namespace YourVendor\YourModule\Block\Adminhtml\Inquiry\Grid\Renderer;

use Magento\Backend\Block\Widget\Grid\Column\Renderer\AbstractRenderer;
use Magento\Framework\Object;
use Magento\Store\Model\StoreManagerInterface;

class Image extends AbstractRenderer
{
    private $_storeManager;
    /**
     * @param \Magento\Backend\Block\Context $context
     * @param array $data
     */
    public function __construct(\Magento\Backend\Block\Context $context, StoreManagerInterface $storemanager, array $data = [])
    {
        $this->_storeManager = $storemanager;
        parent::__construct($context, $data);
        $this->_authorization = $context->getAuthorization();
    }
    /**
     * Renders grid column
     *
     * @param Object $row
     * @return  string
     */
    public function render(Object $row)
    {
        $mediaDirectory = $this->_storeManager->getStore()->getBaseUrl(
            \Magento\Framework\UrlInterface::URL_TYPE_MEDIA
        );
        $imageUrl = $mediaDirectory.'/inquiry/images'.$this->_getValue($row);
        return '<img src="'.$imageUrl.'" width="50"/>';
    }
}

Saya harap ini akan membantu Anda.
