Easy to manage Config variables separate from App code. Useful while developing and deploying( CI/CD) django web-apps
Usage
- You need to subclass the
Config
class. - Any configuration would be loaded from
python config
file(default: env.py)
from the same folder where library is inherited. This file should not be committed to version history. - You also don't need to include a sample file. Since the
Config
object would be able to generateenv.py
itself. - It also loads Configuration variables from environment variables. The preference is
env variables
>env.py
- The config file should define all the variables needed for a project.
- It can also define a prefix to limit environment variables searched.
# project/conf.py
from dynamic_conf import Config
class CONFIG(Config):
"""singleton to be used for configuring from os.environ and env.py"""
# default settings
ENV = "prod" # optional field with a default value
DB_NAME = "db"
DB_HOST = "127.0.0.1"
DB_USER = "postgres"
DB_PASS = None # even None could be given as default value
SECRET_KEY:str # required field. Note: it will not work in Python 2 because
- to create
project/env.py
just run
# you could pass environment variables or set already with export
env DB_PASS='123' dynamic-conf
# or you could pass as list of key-value pair
dynamic-conf DB_USER='user-1' DB_PASS='123'
# to filter environment variables with a prefix
env VARS_PREFIX="PROD_" dynamic-conf PROD_DB_USER="user-2"
- To use the config simply import and use particular attribute
# project/settings.py
from conf import CONFIG
DATABASES = {
"default": {
"ENGINE": "django.contrib.gis.db.backends.postgis",
"HOST": CONFIG.DB_HOST,
"NAME": CONFIG.DB_NAME,
"USER": CONFIG.DB_USER,
"PASSWORD": CONFIG.DB_PASSWORD,
"PORT": "5432",
}
}
