Handling different HTTP methods in Django - Mini Project: Build & Apply

Handling different HTTP methods in Django views

📖 Scenario: You are building a simple Django web app that responds differently to GET and POST requests on the same URL.This is like a restaurant where the waiter listens to different requests: one to show the menu (GET) and one to take your order (POST).

🎯 Goal: Create a Django view function called handle_request that returns a different HTTP response depending on whether the request method is GET or POST.For GET requests, respond with the text 'This is a GET request'. For POST requests, respond with the text 'This is a POST request'.

📋 What You'll Learn

Create a Django view function named handle_request

Use the request.method attribute to check the HTTP method

Return an HttpResponse with the exact text 'This is a GET request' for GET requests

Return an HttpResponse with the exact text 'This is a POST request' for POST requests

💡 Why This Matters

🌍 Real World

Web servers often need to respond differently to GET and POST requests on the same URL, such as showing a form on GET and processing it on POST.

💼 Career

Understanding how to handle different HTTP methods is essential for backend web development and building RESTful APIs.

1

Import HttpResponse and create the view function

Import HttpResponse from django.http and create a function called handle_request that takes request as a parameter.

Django

from django.http import HttpResponse

# Define the view function handle_request with request parameter
# Your code here

Need a hint?

Start by importing HttpResponse and define the function handle_request with request as its argument.

2

Check if the request method is GET

Inside the handle_request function, add an if statement to check if request.method is equal to 'GET'.

Django

from django.http import HttpResponse

def handle_request(request):
    # Check if request.method is 'GET'
    # Your code here

Need a hint?

Use if request.method == 'GET': to check the HTTP method.

3

Return HttpResponse for GET and POST methods

Inside the if block for GET, return HttpResponse('This is a GET request'). Add an elif block to check if request.method is 'POST' and return HttpResponse('This is a POST request').

Django

from django.http import HttpResponse

def handle_request(request):
    if request.method == 'GET':
        # Return HttpResponse for GET
        # Your code here
    elif request.method == 'POST':
        # Return HttpResponse for POST
        # Your code here

Need a hint?

Use return HttpResponse('This is a GET request') inside the GET block and similarly for POST.

4

Add a fallback response for other HTTP methods

Add an else block at the end of the handle_request function that returns HttpResponse('Unsupported HTTP method') for any other HTTP methods.

Django

from django.http import HttpResponse

def handle_request(request):
    if request.method == 'GET':
        return HttpResponse('This is a GET request')
    elif request.method == 'POST':
        return HttpResponse('This is a POST request')
    # Add else block for unsupported methods
    # Your code here

Need a hint?

Use an else block to handle any HTTP methods other than GET and POST.
