View decorators (require_GET, require_POST) in Django - Mini Project: Build & Apply

Using Django View Decorators require_GET and require_POST

📖 Scenario: You are building a simple Django web app that handles user requests differently based on whether the request is a GET or a POST.For example, a GET request will show a welcome message, and a POST request will process form data.

🎯 Goal: Create two Django view functions named welcome_view and submit_view. Use the require_GET decorator on welcome_view to allow only GET requests, and use the require_POST decorator on submit_view to allow only POST requests.

📋 What You'll Learn

Create a Django view function called welcome_view that returns an HttpResponse with the text 'Welcome to the site!'

Create a Django view function called submit_view that returns an HttpResponse with the text 'Form submitted successfully!'

Use the require_GET decorator on welcome_view

Use the require_POST decorator on submit_view

💡 Why This Matters

🌍 Real World

Web developers often need to restrict views to specific HTTP methods to ensure correct behavior and security, such as only allowing form submissions via POST.

💼 Career

Understanding and using Django view decorators like require_GET and require_POST is essential for backend web development roles using Django.

1

Create the initial Django view functions

Create two Django view functions named welcome_view and submit_view. Each should take a request parameter and return an HttpResponse with the exact text 'Welcome to the site!' for welcome_view and 'Form submitted successfully!' for submit_view. Import HttpResponse from django.http.

Django

from django.http import HttpResponse

# Create welcome_view function
# Create submit_view function

Need a hint?

Remember to import HttpResponse from django.http. Define two functions with the exact names and return the specified text.

2

Import the decorators require_GET and require_POST

Add import statements to import require_GET and require_POST from django.views.decorators.http.

Django

from django.http import HttpResponse
# Import require_GET and require_POST decorators here

def welcome_view(request):
    return HttpResponse('Welcome to the site!')

def submit_view(request):
    return HttpResponse('Form submitted successfully!')

Need a hint?

Use a single import line to import both require_GET and require_POST from django.views.decorators.http.

3

Apply the require_GET decorator to welcome_view

Add the @require_GET decorator above the welcome_view function definition to allow only GET requests.

Django

from django.http import HttpResponse
from django.views.decorators.http import require_GET, require_POST

# Add @require_GET decorator here

def welcome_view(request):
    return HttpResponse('Welcome to the site!')

def submit_view(request):
    return HttpResponse('Form submitted successfully!')

Need a hint?

Place @require_GET directly above the welcome_view function definition.

4

Apply the require_POST decorator to submit_view

Add the @require_POST decorator above the submit_view function definition to allow only POST requests.

Django

from django.http import HttpResponse
from django.views.decorators.http import require_GET, require_POST

@require_GET
def welcome_view(request):
    return HttpResponse('Welcome to the site!')

# Add @require_POST decorator here

def submit_view(request):
    return HttpResponse('Form submitted successfully!')

Need a hint?

Place @require_POST directly above the submit_view function definition.
