DEBUG mode behavior in Django - Mini Project: Build & Apply

Understanding DEBUG Mode Behavior in Django

📖 Scenario: You are building a simple Django project. You want to learn how the DEBUG setting affects your project during development.

🎯 Goal: Create a Django settings snippet that sets up the DEBUG mode, configure allowed hosts, and understand how Django behaves differently when DEBUG is True or False.

📋 What You'll Learn

Create a variable called DEBUG and set it to True

Create a list called ALLOWED_HOSTS with one entry: 'localhost'

Add a conditional block that prints 'Debug mode is ON' if DEBUG is True

Add a conditional block that prints 'Debug mode is OFF' if DEBUG is False

💡 Why This Matters

🌍 Real World

Developers use the <code>DEBUG</code> setting to control whether Django shows detailed error messages and debugging information during development.

💼 Career

Understanding <code>DEBUG</code> mode is essential for Django developers to safely develop and deploy web applications.

1

Set DEBUG mode to true

Create a variable called DEBUG and set it to True in your Django settings.

Django

# Your code here

Need a hint?

Use DEBUG = True to enable debug mode.

2

Configure ALLOWED_HOSTS

Create a list called ALLOWED_HOSTS with one string entry: 'localhost'.

Django

DEBUG = True
# Your code here

Need a hint?

Set ALLOWED_HOSTS to a list with 'localhost' inside.

3

Add conditional message for DEBUG true

Add an if statement that checks if DEBUG is True and inside it write print('Debug mode is ON').

Django

DEBUG = True
ALLOWED_HOSTS = ['localhost']
# Your code here

Need a hint?

Use if DEBUG: to check the debug mode and print the message inside.

4

Add conditional message for DEBUG false

Add an else block after the if DEBUG that prints 'Debug mode is OFF'.

Django

DEBUG = True
ALLOWED_HOSTS = ['localhost']
if DEBUG:
    print('Debug mode is ON')
# Your code here

Need a hint?

Use else: to handle the case when DEBUG is False.
