How to validate a condition rules based on product attribute in magento 2
backend:
code:
$product_id = '3'; // Crown Summit Backpack sku is 24-MB03
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$rules = $objectManager->create('Vendor\Module\Model\Rule')->getCollection();
foreach ($rules as $rule) {
$product = $objectManager->get('Magento\Catalog\Model\Product')->load($product_id);
$item = $objectManager->create('Magento\Catalog\Model\Product');
$item->setProduct($product);
$validate = $rule->getActions()->validate($item);
}
var_dump($validate);
var_dump($product);
Expected result is false but it always shows true. validation not done properly on product attributes.
var_dump($validate);
var_dump($product);

Finally i done it, here my updated code
public function execute()
{
$validate = array();
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$quoteId = $this->cart->getQuote()->getId();
$quote = $this->quoteFactory->load($quoteId);
$fakeQuote = clone $quote;
$fakeQuote->setId(null);
$items = $this->cart->getQuote()->getAllItems();
$rules = $objectManager->create('Vendor\Module\Model\Rule')->getCollection();
foreach ($rules as $rule){
foreach($items as $item){
$productId = $item->getProductId();
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($productId);
$quoteItem = $objectManager->create('Magento\Quote\Model\Quote\Item');
$quoteItem->setQuote($fakeQuote)->setProduct($product);
$quoteItem->setAllItems(array($product));
$quoteItem->getProduct()->setProductId($product->getEntityId());
$validate = $rule->getConditions()->validate($quoteItem);
}
}
// var_dump($validate);
return $validate;
}
