What are the best practices for views in Django?

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

1. Use class-based views for reusable code.
2. Keep your views focused on a single responsibility.
3. Use Django's built-in generic views when possible.
4. Avoid complex logic in views; delegate to models or forms.
5. Use decorators for authentication and permissions.

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 applications with many similar views.

What about function-based views? Are they still useful?

Yes, function-based views (FBVs) are still useful, especially for simple views. They are straightforward and easy to understand, making them a good choice for small applications or when you need quick prototyping. However, for larger applications, CBVs often provide better structure.

How can I handle errors in my views?

You can handle errors in your views by using try-except blocks to catch exceptions. Additionally, you can use Django's built-in error handling features, such as returning custom error pages or using middleware to manage errors globally.
