Need an example and please explain me the purpose of python-dotenv.
I am kind of confused with the documentation.
Now we will see solution for issue: What is the use of python-dotenv?
From the Github page:
Reads the key,value pair from .env and adds them to environment variable. It is great of managing app settings during development and in production using 12-factor principles.
Assuming you have created the
.env file along-side your settings module.
. ├── .env └── settings.py
Add the following code to your
# settings.py import os from os.path import join, dirname from dotenv import load_dotenv dotenv_path = join(dirname(__file__), '.env') load_dotenv(dotenv_path) SECRET_KEY = os.environ.get("SECRET_KEY") DATABASE_PASSWORD = os.environ.get("DATABASE_PASSWORD")
.env is a simple text file with each environment variable listed one per line, in the format of KEY=”Value”. The lines starting with # are ignored.
SOME_VAR=someval # I am a comment and that is OK FOO="BAR"
