Correct way of using ViewModel inside of pagebuilder elements?

Question

I have a ViewModel that returns if a user is logged in or not and we need to add this functionality to vendor/magento/module-page-builder/view/frontend/templates/catalog/product/widget/content/carousel.phtml but we're unsure on the correct way to do this.

Cheers

From what I know, you cannot use view models out of the box. But I may be wrong.
But when the widget is rendered it calls the toHtml method from the block. In your case, I think the block is Magento\CatalogWidget\Block\Product\ProductsList.

I think you can create a before plugin on the toHtml method from the block and attach your view model to the block..

something like this

namespace Venrod\Module\Plugin\CatalogWidget\Block;
class ProductsListPlugin
{
 private $viewModel;
 public function __construct(\Your\ViewModel\ClassHere $viewModel)
 {
 $this->viewModel = $viewModel;
 }
}
public function beforeToHtml(
 \Magento\CatalogWidget\Block\Product\ProductsList $subject
) {
 $subject->setData('myViewModel', $this->viewModel);
}

then you should be able to use in your template (which you should overwrite in your theme) this

<php $viewModel = $block->getData('myViewModel');?>

<?php if ($viewModel) : ?>
 your logic goes here
<?php endif;?>

• unknown: Thankyou. I will try this method!
