Flask Config Helper

Helper utility to manage Flask app configuration. FlaskConfig checks that the required config variables are present, and loads them into the app config. It will also check for optional configs, but will not return an error if they are not present.

Installation

pip install flask-confighelper

Usage

The flask-confighelper package will read the ENVIRONMENT key currently set, and will use the value of that key to identify which *Config object to load

app.py

from flask import Flask
from flask_config import FlaskConfigHelper

app = Flask(__name__)
FlaskConfigHelper(app, config_module='config')

print app.config['DATABASE_URI']

config.py

class Config(object):
    PORT = 'required'
    OPTIONAL = 'optional'

class ProductionConfig(Config):
    DATABASE_URI = 'required'
    TOKEN = 'required'
    OPTIONAL = 'optional'

class DevelopmentConfig(Config):
    DATABASE_URI = 'required'
    DEBUG = 'optional'
    OPTIONAL = 'optional'

class TestingConfig(Config):
    TESTING = 'required'
