Configure Flask from environment variables.
Homepage Repository PyPI Python
pip install Flask-EnvConfig==0.2.0
Extension for configuring Flask from environment variables.
- Flask
pip install flask-envconfig
Simple usage:
from flask import Flask from flask.ext.envconfig import EnvConfig app = Flask(__name__) env = EnvConfig(app)
Or, for the application factory pattern:
env = EnvConfig() # At a later time env.init_app(app)
Now set your configuration variables in your shell, .env file or whatever:
FLASK_DEBUG=True FLASK_SECRET_KEY="Something_or_the_other"
By default only environments variables prefixed with FLASK_ are processed and added to app.config. The extension strips off the prefix so FLASK_DEBUG becomes app.config['DEBUG'] and so forth. The extension understands "True" to mean True, "False" to mean False and "None" to mean None. It also understands lists, tuples and dicts and numbers.
FLASK_TRUE=True
FLASK_FALSE=False
FLASK_NONE=None
FLASK_INTEGER=1
FLASK_FLOAT=1.1
FLASK_STRING="This is a string"
FLASK_LIST="['a', 'b', 'c']"
FLASK_TUPLE="('a', 'b', 'c')"
FLASK_DICT="{'a': 1, 'b': 6}"
The prefix can be changed if so desired:
EnvConfig(app, 'MYPREFIX_')
Or
env = EnvConfig() env.init_app(app, 'MYPREFIX_')
