What are the differences between function-based and class-based views in Django?

What are the differences between function-based and class-based views in Django?

Function-based views (FBVs) are simple and straightforward, using functions to handle requests. Class-based views (CBVs) offer more structure and reusability, allowing for inheritance and mixins.

Can you give me an example of each?

Sure! A function-based view might look like this:

from django.http import HttpResponse

def my_view(request):
    return HttpResponse('Hello, World!')

A class-based view would be:

from django.views import View
from django.http import HttpResponse

class MyView(View):
    def get(self, request):
        return HttpResponse('Hello, World!')

When should I use one over the other?

Use function-based views for simple tasks and when you need quick implementations. Opt for class-based views when you need to manage complex logic or reuse code.

Are there any performance differences?

Generally, the performance difference is negligible. The choice should be based on code organization and maintainability rather than speed.
