Django 与 Heroku

Question

尝试在 .env 而不是 settings.py 文件中设置密钥时遇到问题

当我运行 heroku 配置时，我得到了密钥

(portfolio) PS C:\Users\arund\Desktop\Code\Django\portfolio-project> heroku config:get SECRET_KEY
value

当我运行以下内容时出现错误。

(portfolio) PS C:\Users\arund\Desktop\Code\Django\portfolio-project> heroku local

过程文件

Answer 1

Django 不会神奇地将环境变量应用于您的设置。你需要自己做，例如通过你的 settings.py:

这样的东西

import os

SECRET_KEY = os.getenv("SECRET_KEY", default="dev key")

在开发中，您可以使用 .env 文件来填充您的环境，但不应将该文件提交给版本控制。忽略它，并使用 Heroku's config vars instead。它们将被注入到您的应用程序环境中。
