Small lib to manage settings as object for Flask/Bottle/custom apps

Project description

Just a code I use in a few Bottle/Flask-based and a few other projects.

from just_another_settings import EnvSelector, EnvField

class BaseSettings(object):
    DEBUG = True
    # EnvField looks for the variable and fetches it, otherwise use value from default parameter
    MONGOLAB_URL = EnvField('MONGO_URL')
    HOST = EnvField('HOST', default='localhost')


class ProdSettings(BaseSettings):
    DEBUG = False
    HOST = 'example.com'


class DevSettings(BaseSettings):
    pass


# env selector - selects settings base on env values
env_selector = EnvSelector('APP_MODE', 'dev', dev=DevSettings(), prod=ProdSettings())

# value selector - selects settings base on passed(to the `choose` method) value
by_value_selector = ValueSelector(dev=DevSettings(), prod=ProdSettings())

# somewhere in main file:
# env
application.config.from_object(env_selector.choose())
# by value
application.config.from_object(by_value_selector.choose('dev'))
