如何在 linux 上使用 venv 设置 Django 环境变量？

Question

I've tried using Python's os, manually typing the variables into the terminal, and using a.env file to set my environment variables but always get

raise ImproperlyConfigured("The SECRET_KEY setting must not be empty.")
django.core.exceptions.ImproperlyConfigured: The SECRET_KEY setting must not be empty.

Python

# env.py
import os
os.environ['SECRET_KEY'] = '<my secret key>'

Inside.env

export SECRET_KEY=<my secret key>

settings.py

SECRET_KEY = os.getenv("SECRET_KEY")

Running my python script will not make the environment variables persist.

• Ubuntu 20.04.02
• Django 3.1
• Using VSCode

I have double checked the correct venv activated.

What am I doing wrong! Thanks

Answer 1

Django itself does not read .env file. The best way, to enable it is to use django-environ package

Modify you settings.py

import environ
env = environ.Env(
    # set casting, default value
    DEBUG=(bool, False)
)

And.env file

SECRET_KEY=your-secret-key

Answer 2

try if in settings.py exist:

SECRET_KEY = '<my secret key>'
