How to import from config file in Flask?

Question

I have followed the layout of my Flask project from http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world.

I have the following structure:

After a little bit of fiddling (and a little help from the 'net), I could improve this further, by changing the code to include the config to:

app.config.from_object('config.ProductionConfig')

This enables this cool pattern for configurations:

class Config(object):
    DEBUG = True
    DEVELOPMENT = True
    SECRET_KEY = 'do-i-really-need-this'
    FLASK_HTPASSWD_PATH = '/secret/.htpasswd'
    FLASK_SECRET = SECRET_KEY
    DB_HOST = 'database' # a docker link

class ProductionConfig(Config):
    DEVELOPMENT = False
    DEBUG = False
    DB_HOST = 'my.production.database' # not a docker link

What's left now is to see how to integrate testing configs into this, but at least it feels less clumsy.
