hartwork / createcustomsuperuser.py
Created March 30, 2018 16:03
Django management command to script creation of superusers
# Django management command to create custom superusers
# Version 2018.03.18
#
# Core benefits over existing command `createsuperuser` are:
# - Scriptability
# - Ignorance of `settings.AUTH_PASSWORD_VALIDATORS`
# - Idempotency
#
# Store as `<app>/management/commands/createcustomsuperuser.py` to activate.
# Originally written for Django 1.9.9.
