Why settings configuration matters in Django - See It in Action

Why settings configuration matters

📖 Scenario: You are building a simple Django project that needs to handle different environments like development and production. Proper settings configuration helps your project behave correctly in each environment.

🎯 Goal: Create a Django settings file with a base configuration, add a variable to switch between development and production modes, and use that variable to set the debug mode accordingly.

📋 What You'll Learn

Create a dictionary called BASE_SETTINGS with keys INSTALLED_APPS and DATABASES and their exact values

Add a variable called ENVIRONMENT with the value 'development'

Use an if statement to set DEBUG to True if ENVIRONMENT is 'development', else False

Add a final setting ALLOWED_HOSTS as an empty list

💡 Why This Matters

🌍 Real World

In real projects, settings configuration helps your Django app behave correctly in different environments like development, testing, and production.

Understanding settings configuration is essential for Django developers to deploy apps safely and efficiently.

1

Create base settings dictionary

Create a dictionary called BASE_SETTINGS with these exact entries: 'INSTALLED_APPS' set to a list containing 'django.contrib.admin' and 'django.contrib.auth', and 'DATABASES' set to a dictionary with key 'default' mapping to another dictionary with 'ENGINE' set to 'django.db.backends.sqlite3' and 'NAME' set to 'mydatabase'.

Django

# Your code here

Need a hint?

Use a dictionary with keys 'INSTALLED_APPS' and 'DATABASES'. The 'INSTALLED_APPS' value is a list of two strings. The 'DATABASES' value is a nested dictionary.

2

Add environment variable

Add a variable called ENVIRONMENT and set it to the string 'development'.

Django

BASE_SETTINGS = {
    'INSTALLED_APPS': ['django.contrib.admin', 'django.contrib.auth'],
    'DATABASES': {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': 'mydatabase'
        }
    }
}

# Your code here

Need a hint?

Just create a variable named ENVIRONMENT and assign it the string 'development'.

3

Set debug mode based on environment

Use an if statement to set a variable called DEBUG to True if ENVIRONMENT is equal to 'development', otherwise set DEBUG to False.

Django

BASE_SETTINGS = {
    'INSTALLED_APPS': ['django.contrib.admin', 'django.contrib.auth'],
    'DATABASES': {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': 'mydatabase'
        }
    }
}

ENVIRONMENT = 'development'

# Your code here

Need a hint?

Use a simple if-else block comparing ENVIRONMENT to 'development' to set DEBUG.

4

Add allowed hosts setting

Add a variable called ALLOWED_HOSTS and set it to an empty list [].

Django

BASE_SETTINGS = {
    'INSTALLED_APPS': ['django.contrib.admin', 'django.contrib.auth'],
    'DATABASES': {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': 'mydatabase'
        }
    }
}

ENVIRONMENT = 'development'

if ENVIRONMENT == 'development':
    DEBUG = True
else:
    DEBUG = False

# Your code here

Need a hint?

Just create an empty list variable named ALLOWED_HOSTS.
