Request parsing and response rendering in Django - Mini Project: Build & Apply

Request parsing and response rendering in Django

📖 Scenario: You are building a simple Django view that receives a user's name via a URL query parameter and returns a greeting message as an HTTP response.

🎯 Goal: Create a Django view function that parses the name parameter from the request's GET data and returns a plain text greeting message including that name.

📋 What You'll Learn

Create a Django view function named greet_user

Parse the name parameter from request.GET

Set a default name if name is not provided

Return an HttpResponse with a greeting message including the name

Use plain text content type in the response

💡 Why This Matters

🌍 Real World

Parsing request data and sending responses is a core part of building web applications with Django.

💼 Career

Understanding how to handle HTTP requests and responses is essential for backend web developers working with Django.

1

Create the Django view function

Create a Django view function called greet_user that takes a single parameter request.

Django

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

Need a hint?

Start by defining a function named greet_user that accepts request as its only argument.

2

Parse the 'name' parameter from the request

Inside the greet_user function, create a variable called name that gets the name parameter from request.GET. Use "Guest" as the default value if name is not provided.

Django

from django.http import HttpResponse

def greet_user(request):
    # Get the 'name' parameter from request.GET with default 'Guest'
    # Your code here

Need a hint?

Use request.GET.get('name', 'Guest') to safely get the name parameter or default to "Guest".

3

Create the greeting message

Still inside the greet_user function, create a variable called message that uses an f-string to say "Hello, {name}! Welcome to our site.".

Django

from django.http import HttpResponse

def greet_user(request):
    name = request.GET.get('name', 'Guest')
    # Create the greeting message using f-string
    # Your code here

Need a hint?

Use an f-string to include the name variable inside the greeting message.

4

Return the HttpResponse with the greeting

Return an HttpResponse from the greet_user function with the message as content and set the content_type to "text/plain".

Django

from django.http import HttpResponse

def greet_user(request):
    name = request.GET.get('name', 'Guest')
    message = f"Hello, {name}! Welcome to our site."
    # Return HttpResponse with message and content_type 'text/plain'
    # Your code here

Need a hint?

Use return HttpResponse(message, content_type='text/plain') to send the plain text response.
