[Answered ]-How to set multiple settings.py for sites framework django?

you can have multiple setting file for example develop.py and production.py

steps:

1. create a settings folder inside the project
2. Add all of the settings file to that folder
3. while running server

   ./manage.py runserver -- settings=project_name.settings.required_settingfile
   

for example:

./manage.py runserver --settings=myproject.settings.develop

To serve multiple sites from the same Django instance you do not need multilple settings.py files.

A simple method is to omit the SITE_ID setting from the Sites framework. Then include the Sites framework middleware:

'django.contrib.sites.middleware.CurrentSiteMiddleware'

This automatically passes a request object to Site.objects.get_current() on every request. It also allows your Django application to detect the current site via request.site.

You would need to make sure to setup multilple virtual hosts using your NGINX or apache instance to route traffic from each site to your server.
