环境变量在本地和Heroku [英] Environment variables locally and Heroku

问题描述

我有一个sinatra应用程序，我有一个yml文件来设置环境变量，我使用这种方法调用它们

 模块MyConfig 
 
 def config 
 environment = ENV [RACK_ENV] || 开发
 YAML.load_file（./ config / config.yml）[environment] 
 end 
 end 
  

所以当我想使用一个变量我做这个例如

  aws_access_key_id = config ['aws_access_key'] 
  

我有一个.gitignore文件，在推送时忽略config.yml以github为例，当我推到heroku这些环境变量将无法访问？

所以这让我使用英雄的方式设置他们像这样

  heroku config：add aws_access_key = myapikey 
  

，但是英雄们访问这些像

  aws_access_key_id = ENV ['aws_access_key'] 
  

如何设置我的开发环境使用方法配置和英雄使用ENV，我看这个错误的方式？或者我的配置方法为我做这个？

任何帮助赞赏

RAKEFILE

  require'active_support / core_ext'
 require'./config/config.rb'
 require'bundler / setup'
 Bundler.require（：default）
 
 include MyConfig 
 
 AssetSync.configure do | con | 
 con.fog_provider ='AWS'
 con.fog_region ='eu-west-1'
 con.fog_directory = config ['fog_directory'] 
 con.aws_access_key_id = config [ 'aws_access_key'] 
 con.aws_secret_access_key = config ['aws_secret_key'] 
 con.prefix =assets
 con.public_path =路径名（./ public）
 end 
 
命名空间：assets do 
 desc预编译资产
任务：precompile do 
 AssetSync.sync 
 end 
 end 
  

解决方案

更新：

我现在使用 dotenv 宝石，而不是下面的示例。因此，我现在忽略了 env.rb 文件，现在我忽略了使用Git的 .env 文件。

原始帖子

尝试这个，

 ＃/env.rb 
 
 ENV ['aws_bucket'] ='my_bucket'
 ENV ['aws_access_key'] ='my_access_key' 
 ENV ['aws_access_secret'] ='my_access_secret'
  

此文件设置相同的 ENV 值为 heroku config 会做。

 ＃/config.rb 
 
 require'./env'如果File.exists？（' env.rb'）
  

env.rb 只有在存在的情况下才需要。

 ＃/.gitignore 
 
 /env.rb 
  

env.rb 已添加到 .gitignore 文件，因此它不保存在Git中。

然后，您将使用 ENV ['key'] 而不是 config ['key'] 。

您可能需要将路径更改为 env.rb 如果它不在与 config.rb 文件相同的目录中。

编辑：

从上一个问题中查看您的 Rakefile ，您需要将其更改为：

 ＃Rakefile 
 
要求'bundler / setup'
 Bundler.require（：default ）
 require'./env'如果File.exists？（'env.rb'）
 
 AssetSync.configure do | con | 
 con.fog_provider ='AWS'
 con.fog_region ='eu-west-1'
 con.fog_directory = ENV ['aws_bucket'] 
 con.aws_access_key_id = ENV [ 'aws_access_key'] 
 con.aws_secret_access_key = ENV ['aws_access_secret'] 
 con.prefix =assets
 con.public_path =路径名（./ public）
 end 
 
命名空间：assets do 
 desc预编译资产
任务：precompile do 
 AssetSync.sync 
 end 
 end 
  

我假设 /config/config.rb 是 config 方法，所以我删除了，

  require'./config/config.rb'
 include MyConfig 
  

并交换 config [key] for ENV [key] 在 env.rb 。您可能需要更改密钥名称才能匹配。

I have a sinatra app in which i have a yml file to set environment variables, i call them using this method

module MyConfig

 def config
  environment = ENV["RACK_ENV"] || "development"
  YAML.load_file("./config/config.yml")[environment]
 end
 end

so when i want to use a variable i do this for example

aws_access_key_id = config['aws_access_key']

I have a .gitignore file that ignores config.yml when pushing to github for example.So when I push to heroku these environment variables will not be accessible?

So this leaves me with using the heroku way of setting them like so

heroku config:add aws_access_key= myapikey

but heroku accesses these like

aws_access_key_id = ENV['aws_access_key']

How can i set my dev environment to use method config and heroku use ENV, am i looking at this the wrong way? or does my config method do this for me?

Any help appreciated

  con.fog_directory = config['fog_directory']
  con.aws_access_key_id = config['aws_access_key']
  con.aws_secret_access_key = config['aws_secret_key']
  con.prefix = "assets"
  con.public_path = Pathname("./public")
  end

解决方案

Update:

I now use the dotenv gem instead of the example below. So instead of ignoring the env.rb file, I now ignore the .env file with Git.

Original post:

Try this,

# /env.rb

ENV['aws_bucket'] = 'my_bucket'
ENV['aws_access_key'] = 'my_access_key'
ENV['aws_access_secret'] = 'my_access_secret'

This file sets the same ENV values as heroku config would do.

# /config.rb

require './env' if File.exists?('env.rb')

The env.rb will only get required if it exists.

# /.gitignore

/env.rb

The env.rb has been added to the .gitignore file so it isn't kept in Git.

You would then access the values using ENV['key'] instead of config['key'].

You might need to change the path to the env.rb if it's not in the same directory as the config.rb file.

EDIT:

From looking at your Rakefile in the previous question, you need to change it to this:

# Rakefile

require 'bundler/setup'
Bundler.require(:default)
require './env' if File.exists?('env.rb')

AssetSync.configure do |con|
 con.fog_provider = 'AWS'
 con.fog_region = 'eu-west-1'
 con.fog_directory = ENV['aws_bucket']
 con.aws_access_key_id = ENV['aws_access_key']
 con.aws_secret_access_key = ENV['aws_access_secret']
 con.prefix = "assets"
 con.public_path = Pathname("./public")
end

namespace :assets do
  desc "Precompile assets"
  task :precompile do
    AssetSync.sync
  end
end

I've assumed that the only method in /config/config.rb was the config method so I've removed the,

require './config/config.rb'
include MyConfig

And swapped the config[key] for the ENV[key] values defined in env.rb. You may need to change the key names to match up.
