Django settings based on IP or hostname

I'd like t开发者_运维技巧o have something in my settings like

if ip in DEV_IPS:
   SOMESETTING = 'foo'
else:
   SOMESETTING = 'bar'

Is there an easy way to get the ip or hostname - also - is this is a bad idea ?

import socket
socket.gethostbyname(socket.gethostname())

However, I'd recommend against this and instead maintain multiple settings file for each environment you're working with.

settings/__init__.py
settings/qa.py 
settings/production.py

__init__.py has all of your defaults. At the top of qa.py, and any other settings file, the first line has:

from settings import *

followed by any overrides needed for that particular environment.

One method some shops use is to have an environment variable set on each machine. Maybe called "environment". In POSIX systems you can do something like ENVIRONMENT=production in the user's .profile file (this will be slightly different for each shell and OS). Then in settings.py you can do something like this:

import os

if os.environ['ENVIRONMENT'] == 'production':
    # Production
    DATABASE_ENGINE = 'mysql'
    DATABASE_NAME = ....
else:
    # Development
