README

This Magento 2 module demonstrates a dynamic approach to adding extension attributes to orders using plugins and di.xml configuration.

Purpose

The primary purpose of this module is to showcase a flexible and maintainable way to extend the Magento\Sales\Api\Data\OrderInterface with custom attributes. Instead of hardcoding the logic for each attribute in a plugin, this approach uses di.xml to define the mapping between extension attribute codes and their data sources, which can be either existing order data keys or dedicated hydrator classes for complex logic.

Key Features

• Dynamic Extension Attribute Population: Adds extension attributes to orders based on di.xml configuration.
• Flexibility: Easily add or modify extension attributes without changing the plugin's code.
• Maintainability: Keeps code clean and organized, reducing the risk of conflicts and making upgrades smoother.
• Scalability: Supports a growing number of extension attributes without code bloat.
• Hydrator Classes (Optional): Allows for complex attribute logic to be encapsulated in dedicated classes.

Installation

1. Install via Composer (Recommended):

   composer require apedik/test

2. Enable the module:

   bin/magento module:enable apedik_test

3. Run setup upgrade:

   bin/magento setup:upgrade

4. Compile (if needed):

   bin/magento setup:di:compile

5. Flush cache:

   bin/magento cache:flush

Usage

After installation, the module will dynamically add the following extension attributes to orders:

• custom_attribute_1: Populated with the order's customer email.
• custom_attribute_2: Populated with the order's total quantity ordered.
• complex_attribute: Populated with a combination of the customer group ID and order status, calculated by a dedicated hydrator class.

To test the module:

1. Place an order in your Magento store or retrieve an existing order.
2. Observe the extension attributes in the order data (e.g., using bin/magento sales:order:get <order_id> or by inspecting the order in the Magento admin).
