Introducing ‘GeneratedField’: A New Feature in Django 5.0

Django 5.0 introduces an exciting new feature: GeneratedField.

This long-awaited addition empowers developers to create fields with dynamic values directly in the database, reducing Python-side calculations and improving performance.

Let’s dive into this feature and see how it can streamline your Django projects! 🚀

🧐 What is GeneratedField?

GeneratedField is a database-computed field, meaning its value is automatically calculated by the database based on an expression involving other fields in the same model.

The database manages and updates the field without requiring any Python-side calculations.

🔑 Key Benefits:

• Uses the ‘GENERATED ALWAYS’ SQL syntax for computed columns.
• Reduces database query complexity.
• Offloads computations from Python to the database.
• Simplifies maintaining derived data.

💡How to Use GeneratedField

Here’s how you can define and use GeneratedField in your Django models:

Imagine you want to store a user’s full name, derived from their first and last names.
