I use Autoenv. It has one ultimate advantage - you don't need to learn any new tools/commands or execute anything manually. Also it's totally up to your decision where do you want to have the virtualenv. Just put a file `.env` with anything you want to execute automatically (eg. `source venv/bin/activate`) into your project directory, and that's it - it will run any time you'll `cd` or open a new shell there.
