Welcome to PyGento Django App!

+

This is a demonstration of how to use PyGento with Django to access Magento database directly.

+
+ +

Features

+ + +

Quick Start

+
+

1. Configure your database connection in .env file:

+ 
+DB_HOST=localhost
+DB_PORT=3306
+DB_NAME=magento
+DB_USER=magento
+DB_PASSWORD=magento
+DB_CHARSET=utf8mb4
+MAGENTO_EDITION=enterprise
+
+ +

2. Run the Django development server:

+ 
+python manage.py runserver
+
+ +

3. Visit the products page to see Magento products:

+ 
+http://127.0.0.1:8000/products/
+
+
+ +

Example Usage in Code:

+ 
+from models import init_db
+from models.catalog import CatalogProductEntity as Product
+from utils.database import DatabaseConnection
+
+# Initialize database connection
+db_conn = DatabaseConnection()
+engine, Session = init_db(db_conn.get_connection_string())

+# Query products

+
+# Print product SKUs
+for product in products:
+    print(f"SKU: {product.sku}")
+
+# Close session
+session.close()
