How to Get all allow attributes of a product in magento2 and show allow attributes in single product page?

Question

I want to get all allow attributes of a product in single page.

In magento 1.7 i was using below code :

<?php $_attributes = Mage::helper('core')->decorateArray($this->getAllowAttributes()); ?>

But how can i achieve same thing in magento 2 ?

Also I have to display all these attributes in single product page. So how to render configurable.phtml file inside single product page file?

Answer 1

If you have a product object then you can it configurable product

 public function __construct(     ...
    \Magento\Framework\Stdlib\ArrayUtils $arrayUtils,     ....) {     ....
    $this->arrayUtils = $arrayUtils;  .....
}

public function decorateArray($array, $prefix = 'decorated_', $forceSetAll = false)
{
    return $this->arrayUtils->decorateArray( $_product->getTypeInstance()->getConfigurableAttributes($_product), $prefix, $forceSetAll);
}

In Magento-2 you can use like this.

$_attributes = $block->decorateArray($block->getAllowAttributes());

You can use like this,

$this->_product->getTypeInstance()->getConfigurableAttributes($this->_product);
