Identifying View Type and Response Method

from django.views import View
from django.http import JsonResponse
from django.views.decorators.http import require_http_methods

class ProductListView(View):
    def get(self, request):
        products = [{'id': 1, 'name': 'Laptop'}]
        return JsonResponse({'products': products})

@require_http_methods(["GET", "POST"])
def create_order(request):
    if request.method == 'POST':
        return JsonResponse({'status': 'Order created'})
    return JsonResponse({'status': 'Ready to receive order'})

  1. ProductListView is a class-based view handling GET requests, while create_order is a function-based view restricted to GET and POST methods using a decorator.

  2. Both ProductListView and create_order are function-based views and must be decorated with @require_http_methods.

  3. The require_http_methods decorator is unnecessary because Django automatically restricts HTTP methods for all views.

  4. Class-based views cannot return JsonResponse; they can only return TemplateResponse.

Show answer & explanation

Correct answer

ProductListView is a class-based view handling GET requests, while create_order is a function-based view restricted to GET and POST methods using a decorator.

Explanation

Class-based views inherit from View and use HTTP method handlers (get, post, etc.), while function-based views handle all methods in one function. Decorators restrict HTTP methods for function-based views.
