Ruby on Rails环境变量用于开发环境 [英] Ruby on Rails environment variable for development environment

问题描述

只是一个很简单的问题，我无法在stackoverflow上找到答案。

如果对于分段和生产环境变量很容易（例如在heroku上），我如何为我的localhost（开发环境）设置环境变量？ （我在mac上）

截至今天，我为我的api凭据硬编码开发环境，我感到不舒服。

谢谢！

解决方案

使用 dotenv 旨在用于开发中：

将您的应用程序配置添加到项目根目录中的 .env 文件。

  S3_BUCKET =你的宝贝
 SECRET_KEY =你的钱也可以在每行之前添加导出，以便您可以在bash中输入文件。 
 $  .bashrc  
  export S3_BUCKET = YOURS3BUCKET 
 export SECRET_KEY = YOURSECRETKEYGOESHERE 
  
然后在rails应用程序中访问 ENV ['S3_BUCKET ']  
 
Just a quick question to which I couldn't find an answer on stackoverflow. 

If it is easy to have environment variable for staging and production (on heroku for example), how can I set environment variable for my localhost (development environment)? (I am on a mac)

As of today I hardcode my api credential for development environment and I don't feel comfortable with that. 

Thanks !
解决方案
Use dotenv is intended to be used in development:

Add your application configuration to your .env file in the root of your project.
S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE
You may also add export in front of each line so you can source the file in bash.
in .bashrc
export S3_BUCKET=YOURS3BUCKET
export SECRET_KEY=YOURSECRETKEYGOESHERE
Then access in rails app ENV['S3_BUCKET']
