Function-based views basics

📖 Scenario: You are building a simple Django web app that shows a welcome message on the homepage.This app uses function-based views to handle web requests.

🎯 Goal: Create a Django function-based view that returns a simple HTTP response with the text "Welcome to my site!" when the homepage is accessed.

📋 What You'll Learn

Create a function-based view named home_view in views.py

The view must return an HttpResponse with the exact text "Welcome to my site!"

Add a URL pattern in urls.py that maps the root URL '' to home_view

Use only function-based views, no class-based views

💡 Why This Matters

🌍 Real World

Function-based views are the simplest way to handle web requests in Django apps, useful for small projects or simple pages.

💼 Career

Understanding function-based views is essential for Django developers to build and maintain web applications.

1

Create the view function

In views.py, import HttpResponse from django.http. Then create a function called home_view that takes a request parameter.

Django

# Import HttpResponse and define home_view function
# Your code here

Need a hint?

Use def to define the function and import HttpResponse at the top.

2

Return a simple HTTP response

Inside the home_view function, return an HttpResponse with the text "Welcome to my site!".

Django

from django.http import HttpResponse

def home_view(request):
    # Return HttpResponse with welcome text
    # Your code here

Need a hint?

Use return HttpResponse("Welcome to my site!") inside the function.

3

Import the view in urls.py

In urls.py, import the home_view function from views.

Django

# Import home_view from views
# Your code here

Need a hint?

Use from .views import home_view to import the view.

4

Add URL pattern for the homepage

In urls.py, add a URL pattern that maps the root URL '' to the home_view function using path. Make sure to import path from django.urls.

Django

from .views import home_view
# Add URL pattern for '' to home_view
# Your code here

Need a hint?

Use path('', home_view) inside urlpatterns list.
