Create a SECRET_KEY variable with a specific string value

Set DEBUG to False

Add 'localhost' and '127.0.0.1' to ALLOWED_HOSTS

Ensure all settings are in the settings.py file

💡 Why This Matters

🌍 Real World

Every Django project needs a SECRET_KEY and proper security settings to protect user data and prevent attacks.

💼 Career

Understanding how to configure Django security settings is essential for backend developers working with Django web applications.

1

Create the SECRET_KEY variable

In the settings.py file, create a variable called SECRET_KEY and set it exactly to the string 'django-insecure-abc123xyz!@#'.

Django

# Your code here

Need a hint?

The SECRET_KEY is a string that Django uses for cryptographic signing. It should be unique and kept secret.

2

Set DEBUG to false

In the settings.py file, add a variable called DEBUG and set it to False to disable debug mode for security.

Django

SECRET_KEY = 'django-insecure-abc123xyz!@#'
# Your code here

Need a hint?

Setting DEBUG to False helps prevent detailed error messages from showing to users.

3

Add ALLOWED_HOSTS

In the settings.py file, create a list variable called ALLOWED_HOSTS containing exactly 'localhost' and '127.0.0.1'.

Django

SECRET_KEY = 'django-insecure-abc123xyz!@#'
DEBUG = False
# Your code here

Need a hint?

ALLOWED_HOSTS tells Django which hostnames your site can serve. This helps prevent HTTP Host header attacks.

4

Complete security settings in settings.py

Ensure the settings.py file contains the SECRET_KEY, DEBUG, and ALLOWED_HOSTS variables exactly as specified.

Django

SECRET_KEY = 'django-insecure-abc123xyz!@#'
DEBUG = False
ALLOWED_HOSTS = ['localhost', '127.0.0.1']
# Verify all settings are present

Need a hint?

Double-check that all three settings are present and exactly match the required values.
