How to modify/preprocess data before displaying in admin grid in Magento 2

Question

I'd like to make some modifications before displaying it in admin grid. For now all what I want to do is just simply replace 0 and 1 in a column with Yes/No. There are a two ways that come to my mind.

First way is to modify the data before passing them to grid. (How? By an interceptor? Maybe there is there a way to modify the model collection?)

Second way is to make an own ui component that will handle that job.

What's the right way to do it?

Answer 1

As modyfing data for grid only should be, in my opinion, kept around the grid itself I've implemented some small column class modification by:

modyfing the layout column node:

<column name="required" class="\Vendor\ModuleName\Ui\Component\Listing\Column\Yesno">

and creating class \Vendor\ModuleName\Ui\Component\Listing\Column\Yesno:

<?php
namespace \Vendor\ModuleName\Ui\Component\Listing\Column;
use Magento\Framework\View\Element\UiComponentFactory;
use Magento\Framework\View\Element\UiComponent\ContextInterface;
use Magento\Store\Model\StoreManagerInterface;
class Yesno extends \Magento\Ui\Component\Listing\Columns\Column
{
 /**
 * @var \Magento\Store\Model\StoreManagerInterface
 */
 protected $storeManager;
 /**
 * @param ContextInterface $context
 * @param UiComponentFactory $uiComponentFactory
 * @param StoreManagerInterface $storeManager
 * @param array $components
 * @param array $data
 */
 public function __construct(
 ContextInterface $context,
 UiComponentFactory $uiComponentFactory,
 StoreManagerInterface $storeManager,
 array $components = [],
 array $data = []
 ) {
 $this->storeManager = $storeManager;
 parent::__construct($context, $uiComponentFactory, $components, $data);
 }
 /**
 * Prepare Data Source
 *
 * @param array $dataSource
 * @return array
 */
 public function prepareDataSource(array $dataSource)
 {
 if(isset($dataSource['data']['items'])) {
 foreach($dataSource['data']['items'] as & $item) {
 if($item) {
 $item['required'] = ($item['required'] == 1 ? __('Yes') : new __('No'));
 }
 }
 }
 return $dataSource;
 }
}
