Scalable Project Architecture & Env Isolation

1. Deep Architecture

In standard Python applications, dependencies are resolved dynamically through the sys.path search list. At startup, Django compiles settings variables into a read-only object namespace. A clean environment separation uses OS-level environment variables to prevent credentials leaks. We use python-decouple to cast variables with default fallbacks, preventing startup failures.

2. The Feynman Gatekeeper

[KNOWLEDGE CHECK] Explain why hardcoding a SECRET_KEY inside settings.py is a security risk, and describe how Django handles settings compilation dynamically at runtime.

3. The Code

# config/settings.py
import os
from pathlib import Path
from decouple import config

BASE_DIR = Path(__file__).resolve().parent.parent
SECRET_KEY = config('DJANGO_SECRET_KEY', default='unsafe-fallback-key')
DEBUG = config('DJANGO_DEBUG', default=False, cast=bool)
ALLOWED_HOSTS = config('DJANGO_ALLOWED_HOSTS', default='127.0.0.1,localhost').split(',')
