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. Keep business logic out of views by using services or models.

Can you explain why class-based views are better?

Class-based views (CBVs) promote code reuse and organization. They allow you to define common behavior in a base class and extend it in subclasses, making your code DRY (Don't Repeat Yourself). This is especially useful for complex views that share similar logic.

What about using function-based views?

Function-based views (FBVs) are simpler and can be more intuitive for straightforward tasks. They are great for small applications or simple views where the overhead of a class might not be justified. However, for larger applications, CBVs can help manage complexity better.

How can I handle exceptions in my views?

You can handle exceptions in your views by using try-except blocks. Additionally, Django provides middleware for handling errors globally, and you can also use custom error views to provide user-friendly error messages.
