无法识别 rails 中 S3.yml 中的 ENV 变量 [英] Not recognizning ENV variables in S3.yml in rails

问题描述

我目前正在尝试使用最新的 aws-sdk 建议 gem 配置 Paperclip.

I'm currently trying to configure Paperclip with newest aws-sdk suggested gem.

在我的 S3.yml 文件中，我有这样的东西

On my S3.yml file I have something like this

development:
  bucket: newmeeter-dev
  access_key_id: ENV['S3_KEY']
  secret_access_key: ENV['S3_SECRET']

但它无法识别 ENV 变量.我收到以下错误

But it is not recognizing the ENV variables. I'm getting the following error

AWS::S3::Errors::InvalidAccessKeyId in PhotosController#create

The AWS Access Key Id you provided does not exist in our records.

如果我尝试将访问和秘密都直接放入文件中，它就可以完美运行.同时，我尝试将两个 ENV 变量打印到视图或控制台中，我可以看到它们的值.

If I try to put both the access and secret directly into the file it works perfectly. At the same time I tried to print both ENV variables into the views or in the console I can see their values okay.

我不明白为什么它不能识别它.

I'm not getting why it is not recognizing it.

推荐答案

已解决！

我在这里找到了这个问题的回复Ruby on Rails:你能将 Ruby 代码放在 YAML 配置文件中?

I found the reply to this question here Ruby on Rails: Can you put Ruby code in a YAML config file?

解决方案:YAML 文件理解 ERB 格式的代码.

Solution: YAML files understand code in ERB format.

在 <%= 和 %> 中打印 ENV 变量是有效的.

Printing ENV variables inside <%= and %> works.

access_key_id: <%= ENV['S3_KEY'] %>
secret_access_key: <%= ENV['S3_SECRET'] %>
