Running Django 1.5 and Django 1.3 on the same server

Question

I have two websites hosted on the same machine. Both of them are developed using Django 1.3.

Now I need to move one site (website1) to the latest version of Django i.e. 1.5

Is it possible to do this? How should I set up the sites so that both work seamlessly?

Answer 1

virtualenv package will help:

virtualenv is a tool to create isolated Python environments.

It's somewhat tricky to activate virtualenv in the wsgi file, but there is a lot of info on the subject out there:

• Deploying django on mod_wsgi, virtualenv
• Setting up Apache and Python WSGI to use VirtualEnv
• django+mod_wsgi on virtualenv not working
• Django/Apache/mod_wsgi not using virtualenv's Python binary
• Django, mod_wsgi and virtual env

Answer 2

Yes, use virtualenv, and in your wsgi script add this:

import os, sys    
sys.path.insert(0, '/path/to/mysite') #where your site is
activate_this = '/path/to/djangoenv/bin/activate_this.py' #virtualenv with proper Django version
execfile(activate_this, dict(__file__=activate_this))
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
