How To get the collection from the ViewModel
Package name : Tridhya
Module : Blog
For fetching the data or getting the collection of the table we can use the ViewModel. Below is a short example that how we can fetch the collection data from the viewmodel
- Declare view model in the layout file
app\code\Tridhya\Blog\view\frontend\layout\blog_index_index.xml
Code:
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceContainer name="content">
<block class="Magento\Framework\View\Element\Template" name="blog.list" template="Tridhya_Blog::blog.phtml">
<arguments>
<argument name="view_model" xsi:type="object">Tridhya\Blog\ViewModel\Data</argument>
</arguments>
</block>
</referenceContainer>
</body>
</page>
- Create pltml file in path: app\code\Tridhya\Blog\view\frontend\templates\blog.phtml from the file we can load the view model with the name which we have passed in the arguments “view_model”
Code:
<?php
$viewModel= $block->getData('view_model');
$blogs = $viewModel->getCollection();
?>
- Create a file in path : app\code\Tridhya\Blog\ViewModel\Data.php
Code:
<?php
namespace Tridhya\Blog\ViewModel;
class Data implements \Magento\Framework\View\Element\Block\ArgumentInterface
{
protected $blogFactory;
public function __construct(
\Tridhya\Blog\Model\BlogFactory $blogFactory
) {
$this->blogFactory = $blogFactory;
}
public function getCollection() {
$blogFactory = $this->blogFactory->create();
$collection = $blogFactory->getCollection();
return $collection;
}
}
?>
