Recall & Review

beginner

What is the main purpose of using environment-based settings in Django?

To separate configuration for different environments like development, testing, and production, making the app more secure and easier to manage.

beginner

How can you load environment variables in a Django project?

By using packages like python-decouple or django-environ, or by accessing os.environ directly in your settings file.

beginner

Why should sensitive information like secret keys and database passwords be stored in environment variables?

To avoid exposing them in the codebase, which improves security and prevents accidental leaks when sharing or publishing code.

intermediate

What is a common pattern to organize Django settings for multiple environments?

Create a base settings file with common settings, then create separate files for development, testing, and production that import from base and override specific values.

beginner

How does using environment-based settings help when deploying a Django app to different servers?

It allows each server to have its own configuration without changing the code, making deployment smoother and reducing errors.

Which Python module is commonly used to access environment variables in Django settings?

B sys

C json

D os

The os module provides access to environment variables via os.environ.

What is the benefit of separating settings into base, development, and production files?

python-decouple helps load environment variables and keep settings clean.

How do environment-based settings improve security?

A By hiding sensitive info from the codebase

B By making the app run faster

C By reducing the number of files

D By disabling debug mode automatically

Storing secrets outside the code prevents accidental exposure and improves security.

Explain how you would set up environment-based settings in a Django project.

Think about separating common and environment-specific settings.

Why is it important to avoid hardcoding secrets in Django settings, and how do environment-based settings help?

Consider security and deployment needs.
