[django] CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False

I'm using Django 1.6.5 with the setting:

DEBUG = True

When I change to DEBUG = False and run manage.py runserver, I get the following error:

CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False

I get the same error with the following setting:

ALLOWED_HOSTS = ['127.0.0.1', 'localhost']

How can I fix this?

This question is related to django

The answer is

Try

ALLOWED_HOSTS = ['*']

Less secure if you're not firewalled off or on a public LAN, but it's what I use and it works.

EDIT: Interestingly enough I've been needing to add this to a few of my 1.8 projects even when DEBUG = True. Very unsure why.

EDIT: This is due to a Django security update as mentioned in my comment.
