What are some examples of function-based views in Django?

Function-based views (FBVs) in Django are simple Python functions that take a web request and return a web response. For example, a basic view could look like this:

from django.http import HttpResponse

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

This view responds with 'Hello, World!' when accessed.

Can you show me a more complex example?

Sure! Here's a more complex example that handles a form submission:

from django.shortcuts import render
from django.http import HttpResponse


def submit_form(request):
    if request.method == 'POST':
        name = request.POST.get('name')
        return HttpResponse(f'Thank you, {name}!')
    return render(request, 'form.html')

This view checks if the request method is POST, processes the form data, and returns a thank you message.

What about using decorators with function-based views?

Great question! You can use decorators to add functionality to your FBVs. For example, using the @login_required decorator:

from django.contrib.auth.decorators import login_required

@login_required
def profile_view(request):
    return render(request, 'profile.html')

This ensures that only logged-in users can access the profile_view.

Are there any best practices for using function-based views?

Yes, some best practices include keeping your views simple and focused, using decorators for common tasks (like authentication), and separating business logic into models or services to keep your views clean.
