This is the script I used to create a virtual environment for testing mezzanine + django-modeltranslation

test_mezzanine_modeltranslation.sh

#!/bin/sh


export PROJ_NAME='mezzanine_modeltranslation'
export VENV_NAME=$PROJ_NAME'_env'

#doc for virtualenv -> http://pypi.python.org/pypi/virtualenv
echo "This install the test environment for mezzanine + django-modeltranslation"
#The rest of the instructions at the end so they are not visible when using a target

if [ "$PIP_DOWNLOAD_CACHE" = "" ];then
    echo "Please set a $PIP_DOWNLOAD_CACHE environment variable. You'll thank me later :-)"
fi

#--no-site-packages : ignores the global site-packages directory (default behavior)
#--distribute : a better setuptools

if [ "$1" = "create_env" ];then
    virtualenv --distribute -p /usr/bin/python $VENV_NAME
    cd $VENV_NAME
    source bin/activate
    bin/pip install mezzanine
    echo "Creating the '$PROJ_NAME' mezzanine project"
    mezzanine-project $PROJ_NAME
    cd $PROJ_NAME
    git init
    echo "Getting the source from github ..."
    git remote add origin [email protected]:catalpainternational/$PROJ_NAME.git
    git fetch origin
    git checkout -f -t origin/master -b master
    echo "Getting the depedencies"
    ../bin/pip install -r requirements.txt
    exit
fi

echo "It assumes that python, pip , distribute & virtualenv are already installed."

echo Usage:
echo
echo "$0 create_env"
echo
echo It will create the virtualenv, mezzanine project, get the source from github and install the pip requirements.
