💡 Hint

Common Mistakes

Using request.POST which is for form data, not raw JSON.

Trying to parse request.GET which is for URL parameters.

The request.body contains the raw bytes of the request payload. We decode it and parse JSON.

3fill in blank

hard

Fix the error in the code to return a JSON response with a status code 201.

Django

from django.http import JsonResponse

def create_item(request):
    response = JsonResponse({'message': 'Created'})
    response.[1] = 201
    return response

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'status' or 'statusCode' which are not valid attributes.

Trying to pass status code as a parameter after creating the response.

The correct attribute to set the HTTP status code on a Django HttpResponse or JsonResponse object is status_code.

4fill in blank

hard

Fill both blanks to parse JSON data and return a JsonResponse with a custom status code.

Django

import json
from django.http import JsonResponse

def update_view(request):
    data = json.loads(request.[1].decode('utf-8'))
    return JsonResponse({'updated': data}, status=[2])

Drag options to blanks, or click blank then click option'

D200

💡 Hint

Common Mistakes

Using request.POST instead of request.body for JSON data.

Using status code 201 for update instead of 200.

Use request.body to get raw data and status=200 to indicate success.

5fill in blank

hard

Fill all three blanks to parse JSON from request, extract a field, and return it in JsonResponse.

Django

import json
from django.http import JsonResponse

def echo_name(request):
    data = json.loads(request.[1].decode('utf-8'))
    name = data.get('[2]', 'Guest')
    return JsonResponse({'name_echo': [3])

Drag options to blanks, or click blank then click option'

Abody

Busername

Cname

Attempts:

💡 Hint

Common Mistakes

Using 'username' instead of 'name' as the key.

Returning the string 'name' instead of the variable.

We read JSON from request.body, get the 'name' field, and return it in the response.
