Django settings.py mini-tip: the `path` lambda

There are a few things I do every time I start a new Django site, and one of those things is add my path lambda to the top of settings.py:

    import os
    ROOT = os.path.abspath(os.path.dirname(__file__))
    path = lambda *args: os.path.join(ROOT, *args)

From then on, it's drop-dead simple to create absolute paths which are relative to the root of the project (or, at least, the directory which contains settings.py). For example:

    >>> path('media/')
    '/Users/wolever/code/review_anywhere/media/

And some other places where it is useful:

    DATABASE_ENGINE = 'sqlite3'
    DATABASE_NAME = path('db.sqlite3')
    ...
    TEMPLATE_DIRS = (
        path('templates/'),
    )
    ...
    DATA_DIR = path('data/')
    ...
