Django Best Practices
When working with Django, there are certain best practices that you should follow to ensure the quality and maintainability of your code. Here are some Django best practices:
Use Class-Based Views
Class-based views offer a more object-oriented approach to handling requests in Django. They provide better code organization and reusability compared to function-based views.
Django ORM
Take advantage of Django’s powerful Object-Relational Mapping (ORM) to interact with your database. Use models to define your application’s data structure and leverage the ORM for database queries.
Django Admin
The Django admin interface is a powerful tool for managing your application’s data. Customize the admin interface to make it user-friendly for content editors and administrators.
Advanced Django Tips
