The code attempts to access nested dictionary keys without ensuring the parent dictionaries exist. This will raise a KeyError if STORAGES is not already defined or if the 'default'/'staticfiles' keys don't exist. Consider using STORAGES.setdefault('default', {})['BACKEND'] = defaultfile_storage or ensure STORAGES is properly initialized first.

Suggested change

	if defaultfile_storage:
	STORAGES["default"]["BACKEND"] = defaultfile_storage
	staticfiles_storage = os.environ.get("STATICFILES_STORAGE")
	if staticfiles_storage:
	STORAGES["staticfiles"]["BACKEND"] = staticfiles_storage
	# Ensure STORAGES is defined
	if "STORAGES" not in globals():
	STORAGES = {}
	if defaultfile_storage:
	STORAGES.setdefault("default", {})["BACKEND"] = defaultfile_storage
	staticfiles_storage = os.environ.get("STATICFILES_STORAGE")
	if staticfiles_storage:
	STORAGES.setdefault("staticfiles", {})["BACKEND"] = staticfiles_storage

the credentials side of this looks good to me. I put in a suggestion that I would like you to use (being consistent about the presence of underscores between environment variable name and corresponding variable name), but I'm not marking as request changes because it's a nitpick.
