Monkey patch Django runserver command

I want to add --env=prod/beta/alpha/dev to runserver so i can do python manage.py runserver --env=prod for example.

I've tried to add to settings.py:

parser = CommandParser(None)
parser.add_argument('--env')
parser.add_argument('args', nargs='*')  # catch-all

try:
    options, args = parser.parse_known_args(sys.argv[2:])
except CommandError:
    pass  # Ignore any option errors at this point.

APP_ENV = options.env or 'dev'

But I got:

usage: manage.py runserver [-h] [--version] [-v {0,1,2,3}]
                       [--settings SETTINGS] [--pythonpath PYTHONPATH]
                       [--traceback] [--no-color] [--ipv6] [--nothreading]
                       [--noreload] [--nostatic] [--insecure]
                       [addrport]
manage.py runserver: error: unrecognized arguments: --env=beta

Any idea how can I monkey patch runserver?

To modify runserver, you could create a custom management command. You should be able to subclass runserver and add the extra arguments.

You might find it easier to set an environment variable, rather than changing the runserver command. In your settings, you would do something like:

import os
env = os.getenv('ENV') or 'dev'

Then you would run the dev server with

ENV=dev python manage.py runserver
