virtualenv postactivate and postdeactivate files for django. Place these files at $VIRTUAL_ENV/bin. That is inside the bin folder inside the virtualenv directory

postactivate

#!/bin/bash
# This hook is run after this virtualenv is activated.
# Place this file at $VIRTUAL_ENV/bin

# I usually drop something like this into my virtualenv's postactivate for some 
# quick and handy shortcuts to common Django commands.
# This way dropping in to do some work on any arbitrary project is as easy as:
# 1. workon <project name>
# 2. djr

#Django command shortcuts
