fabric + virtualenv + django copy remote db (*) to local (in my case sqlite)

fabfile.py

def production():
    env.hosts = ['you.web.server']
    env.user = 'something'
    env.project_root = '/path/to/your.project/'
    env.activate = 'source /path.to/your/virtualenv/bin/activate' # virtualenv

def virtualenv(command):
    run(env.activate + '&&' + command)

def copy_db_to_local():
    output_name = "output_data.json"
    with cd(env.project_root):
        virtualenv("python manage.py dumpdata -v0 --natural > %s" % output_name)
        get(output_name, output_name)
        run("rm -f %s" % output_name)
    local("rm -f database.sql3")
    local("python manage.py syncdb -v0 --noinput") # with django 1.5: --no-initial-data 
    local("python manage.py migrate -v0 --no-initial-data --noinput")
    local("python manage.py sqlflush -v0 | python manage.py dbshell")
    local("python manage.py loaddata -v0 %s" % output_name)
    local("rm -f %s" % output_name)
