What are the best practices for Django views?

When creating Django views, it's important to keep them clean and maintainable. Here are some best practices:

1. Use class-based views for reusable code.
2. Keep views focused on a single responsibility.
3. Use Django's built-in generic views when possible.
4. Handle exceptions gracefully.
5. Use decorators for authentication and permissions.

Can you explain why class-based views are better?

Class-based views promote code reuse and organization. They allow you to define methods for different HTTP methods (GET, POST, etc.) and can be easily extended or modified.

What about using function-based views?

Function-based views are simpler and can be more intuitive for small applications. They are great for straightforward logic but can become unwieldy as complexity grows.

How do I handle exceptions in Django views?

You can handle exceptions in Django views by using try-except blocks. Additionally, you can create custom error views to manage different types of errors gracefully.

What are some common mistakes to avoid in Django views?

Common mistakes include:

1. Writing overly complex views.
2. Not using Django's built-in features.
3. Failing to handle exceptions properly.
4. Mixing business logic with presentation logic.
