# Ansible doesn't expose the shell environment of the remotely logged in user
# so we need to use a few tricks to get some of these values.
#
# This playbook demonstrates how to get a couple of useful environment variables.
#
# NOTE: these values are different to ansible_env.ansible_user_dir and
#       ansible_env.ansible_user_shell which represent the user running ansible.

"""
Two things are wrong with Django's default `SECRET_KEY` system:

1. It is not random but pseudo-random
2. It saves and displays the SECRET_KEY in `settings.py`

This snippet
1. uses `SystemRandom()` instead to generate a random key
2. saves a local `secret.txt`
