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.
从 .env 读取键值对并将它们添加到环境变量中。使用 12 要素原则在开发和生产期间管理应用程序设置非常有用。
Assuming you have created the .env file along-side your settings module.
假设您已经在设置模块旁边创建了 .env 文件。
.
├── .env
└── settings.py
Add the following code to your settings.py
将以下代码添加到您的 settings.py
# 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 variables listed per line, in the format of KEY="Value", lines starting with # is ignored.
.env 是一个简单的文本文件。每行列出每个环境变量，格式为 KEY="Value"，以 # 开头的行将被忽略。
SOME_VAR=someval
# I am a comment and that is OK
FOO="BAR"
