Product Import Strategies in Magento 2 – Part 2: The Hybrid Approach

    Magendoo Insights

    Introduction

    Following our exploration of the DTO approach in Part 1, we’ll now dive into the Hybrid approach for product imports. This method combines programmatic product creation with CSV data enrichment, offering flexibility while maintaining control over the core product structure.

    System Architecture

    Implementation

    1. Base Product Generator

    namespace Vendor\Module\Model;
    
    class BaseProductGenerator
    {
        private $productFactory;
        private $attributeSetRepository;
        private $storeManager;
    
        public function createBaseProduct(string $sku): ProductInterface
        {
            $product = $this->productFactory->create();
    
            $product->setSku($sku)
                ->setAttributeSetId($this->getDefaultAttributeSetId())
                ->setStatus(\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED)
                ->setTypeId(\Magento\Catalog\Model\Product\Type::TYPE_SIMPLE)
                ->setVisibility(\Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH)
                ->setWebsiteIds($this->getWebsiteIds());
    
            return $product;
        }
    
        private function getDefaultAttributeSetId(): int
        {
            return $this->attributeSetRepository->get(4)->getAttributeSetId();
        }
    
        private function getWebsiteIds(): array
        {
            return array_keys($this->storeManager->getWebsites());
        }
    }

    2. Product Enricher

    namespace Vendor\Module\Model;
    
    class ProductEnricher
    {
        private $productRepository;
        private $mediaProcessor;
        private $attributeProcessor;
    
        public function enrichFromCsv(ProductInterface $product, array $data): void
        {
            $this->processBasicAttributes($product, $data);
            $this->processCustomAttributes($product, $data);
            $this->processCategories($product, $data);
            $this->processImages($product, $data);
            $this->processInventory($product, $data);
    
            $this->productRepository->save($product);
        }
    
        private function processBasicAttributes(ProductInterface $product, array $data): void
        {
            $basicAttributes = [
                'name' => $data['name'] ?? '',
                'price' => $data['price'] ?? null,
                'description' => $data['description'] ?? '',
                'short_description' => $data['short_description'] ?? ''
            ];
    
            foreach ($basicAttributes as $code => $value) {
                if ($value !== null) {
                    $product->setData($code, $value);
                }
            }
        }
    
        private function processCustomAttributes(ProductInterface $product, array $data): void
        {
            foreach ($data as $code => $value) {
                if ($this->attributeProcessor->isCustomAttribute($code)) {
                    $this->attributeProcessor->processAttribute($product, $code, $value);
                }
            }
        }
    }

    3. Import Service

    namespace Vendor\Module\Service;
    
    class HybridImportService
    {
        private $baseGenerator;
        private $enricher;
        private $indexerRegistry;
        private $logger;
    
        public function import(string $filePath): ImportResult
        {
            $result = new ImportResult();
    
            try {
                $this->disableIndexers();
    
                foreach ($this->readCsvInChunks($filePath) as $row) {
                    try {
                        $product = $this->baseGenerator->createBaseProduct($row['sku']);
                        $this->enricher->enrichFromCsv($product, $row);
                        $result->addSuccess($row['sku']);
                    } catch (\Exception $e) {
                        $result->addError($row['sku'], $e->getMessage());
                        $this->logger->error($e->getMessage(), ['sku' => $row['sku']]);
                    }
                }
    
                $this->reindexAffectedProducts($result->getSuccessful());
            } catch (\Exception $e) {
                $result->setFatalError($e->getMessage());
            } finally {
                $this->enableIndexers();
            }
    
            return $result;
        }
    
        private function disableIndexers(): void
        {
            foreach ($this->getIndexers() as $indexer) {
                $indexer->setScheduled(true);
            }
        }
    
        private function reindexAffectedProducts(array $skus): void
        {
            // Reindex only affected products
        }
    }

    Advanced Features

    1. Attribute Processing

    namespace Vendor\Module\Model;
    
    class AttributeProcessor
    {
        private $eavConfig;
        private $storeManager;
    
        public function processAttribute(ProductInterface $product, string $code, $value): void
        {
            $attribute = $this->eavConfig->getAttribute('catalog_product', $code);
    
            switch ($attribute->getFrontendInput()) {
                case 'select':
                    $this->processSelectAttribute($product, $attribute, $value);
                    break;
                case 'multiselect':
                    $this->processMultiselectAttribute($product, $attribute, $value);
                    break;
                // Handle other attribute types
            }
        }
    
        private function processSelectAttribute(ProductInterface $product, $attribute, $value): void
        {
            $optionId = $this->getOptionId($attribute, $value);
            $product->setData($attribute->getAttributeCode(), $optionId);
        }
    }

    2. Transaction Management

    namespace Vendor\Module\Model;
    
    class TransactionManager
    {
        private $resource;
    
        public function execute(callable $callback): void
        {
            $connection = $this->resource->getConnection();
            $connection->beginTransaction();
    
            try {
                $callback();
                $connection->commit();
            } catch (\Exception $e) {
                $connection->rollBack();
                throw $e;
            }
        }
    }

    Best Practices

    1. Performance Optimization

    • Use bulk save operations
    • Manage indexers effectively
    • Implement batch processing
    • Cache attribute options and configurations

    2. Error Recovery

    namespace Vendor\Module\Model;
    
    class ErrorRecovery
    {
        private $logger;
        private $emailNotifier;
    
        public function handleError(\Exception $e, array $context): void
        {
            $this->logger->critical($e->getMessage(), $context);
    
            if ($this->isRecoverable($e)) {
                $this->attemptRecovery($context);
            } else {
                $this->notifyAdmin($e, $context);
            }
        }
    
        private function attemptRecovery(array $context): void
        {
            // Implement recovery logic
            $this->cleanupTemporaryFiles();
            $this->restoreIndexers();
            $this->unlockImportProcess();
        }
    }

    Advantages of Hybrid Approach

    Next Steps

    In Part 3, we’ll explore the Middleware approach, which uses a lightweight service to handle data transformation and image processing before import.
