mkdjangovirtualenv: an easier way to setup a virtualenv for a django project

The problem

Lately my process for getting a django project setup in a new environment has looked like:

  1. make sure pip, virtualenv, and virtualenvwrapper are installed
  2. assuming it’s a git repo—clone the project
  3. cd into the project
  4. mkvirtualenv -a pwd -r requirements.txt project_name
  5. set PYTHONPATH and DJANGO_SETTINGS_PROJECT inside ~/.virtualenvs/project_name/bin/postactivate
  6. init and update git submodules

I often forget to add the extra arguments for step 3, step 4 is busywork, and step 5 is something I generally don’t run into until my project fails to find code from a submodule.

The solution

I wrote a script to handle steps 3–6. You can install it from PyPI with pip or easy_intall:

sudo pip install mkdjangovirtualenv

For best results, you should also source mkdjangovirtualenv.sh in your startup script (e.g., ~/.bash_profile, ~/.profile). You can find where the script is located by running which mkdjangovirtualenv.sh:

source /usr/local/bin/mkdjangovirtualenv.sh

Usage:

mkdjangovirtualenv [--settings DJANGO_SETTINGS_MODULE] ENV_NAME [PROJECT_DIR]

For example, to make an env named "radical" for a project in the directory "cowabunga":

mkdjangovirtualenv radical cowabunga/

If you don’t give a path at the end, it will use whatever your current working directory is as the default project path.

The django settings module defaults to "project.settings".* Change it with the --settings flag. Here’s how to make an env named “monkey_business” that has a settings module of “monkeys.settings”:

mkdjangovirtualenv --settings monkeys.settings monkey_business

More info and source code can be found on the github page for this project. Give it a try, let me know if it’s useful for you or if you run into issues.

*I like to name my django project’s "project", since they’d often otherwise have a redundant name to their parent folders.
