Question

我试图弄清楚在开发中设置我的凭据的最佳方法是什么？由于heroku的配置变量，我能够在生产中设置凭据......但如果您只是在本地测试应用程序，则需要帮助。

我在development.rb

中有这个

config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['BUCKET_NAME'],
    :access_key_id => ENV['ACCESS_KEY_ID'],
    :secret_access_key => ENV['SECRET_ACCESS_KEY']
  }
}

但是，我不确定如何引用这些ENV变量？

我在 / config 文件夹

中创建了此aws.yml文件

development:
  BUCKET_NAME: "somename"
  ACCESS_KEY_ID: "4205823951412980"
  SECRET_ACCESS_KEY: "123141ABNCEFEHUDSL2309489850"

我想如果我匹配ENV名称，它会起作用吗？我猜那不是这样的......

我确保将aws.yml包含在我的.ignore文件

中

/config/aws.yml

您正在寻找dotenv宝石。然后安装gem gem 'dotenv-rails', :groups => [:development, :test] 只需创建和`.env＆＃39;文件并将变量放入其中。

S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE

我喜欢在 ./ config 目录中创建 config.yml 。

然后我告诉 ./ config / application.rb 我有一个加载变量的小块，如

config.before_initialize do
  dev = File.join(Rails.root, 'config', 'config.yml')
  YAML.load(File.open(dev)).each do |key,value|
    ENV[key.to_s] = value
  end if File.exists?(dev)
end

这是我的 ./ config / config.yml

BUCKET_NAME: "somename"
ACCESS_KEY_ID: "4205823951412980"
SECRET_ACCESS_KEY: "123141ABNCEFEHUDSL2309489850"

这是我的#config / application.rb

的副本

#config/application.rb
require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(*Rails.groups)

    module Appname
      class Application < Rails::Application
        # Settings in config/environments/* take precedence over those specified here.
        # Application configuration should go into files in config/initializers
        # -- all .rb files in that directory are automatically loaded.

        # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
        # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
        # config.time_zone = 'Central Time (US & Canada)'

        # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
        # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
        # config.i18n.default_locale = :de

        # Do not swallow errors in after_commit/after_rollback callbacks.
        config.active_record.raise_in_transactional_callbacks = true

        initializer 'setup_asset_pipeline', :group => :all  do |app|
          # We don't want the default of everything that isn't js or css, because it pulls too many things in
          app.config.assets.precompile.shift

          # Explicitly register the extensions we are interested in compiling
          app.config.assets.precompile.push(Proc.new do |path|
            File.extname(path).in? [
              '.html', '.erb', '.haml',                 # Templates
              '.png',  '.gif', '.jpg', '.jpeg',         # Images
              '.eot',  '.otf', '.svc', '.woff', '.ttf', # Fonts
            ]
          end)
        end

        I18n.enforce_available_locales = false

        config.before_initialize do
          dev = File.join(Rails.root, 'config', 'config.yml')
          YAML.load(File.open(dev)).each do |key,value|
            ENV[key.to_s] = value
          end if File.exists?(dev)
        end
      end
    end

我喜欢在本地使用 Foreman ，并将所有变量存储在 .ENV 文件中。与Heroku合作很好，易于管理。在我的情况下，我有以下内容：

在 config / initiliazers / aws.rb

下

require 'aws-sdk'
require 'aws-sdk-resources'

# Rails.configuration.aws is used by AWS, Paperclip, and S3DirectUpload
Rails.configuration.aws = YAML.load(ERB.new(File.read("#{Rails.root}/config/aws.yml")).result)[Rails.env].symbolize_keys!
AWS.config(logger: Rails.logger)
AWS.config(Rails.configuration.aws)

在config / initializers / paperclip.rb

下

# https://devcenter.heroku.com/articles/paperclip-s3
if Rails.env.test?
  Paperclip::Attachment.default_options.merge!(
    path: ":rails_root/public/paperclip/:rails_env/:class/:attachment/:id_partition/:filename",
    storage: :filesystem
  )
else
  Paperclip::Attachment.default_options.merge!(
    url: ':s3_domain_url',
    path: '/:class/:filename',
    storage: :s3,
    s3_credentials: Rails.configuration.aws,
    s3_protocol: 'https'
  )
end

在config / aws.yml

下

defaults: &defaults
  access_key_id: <%= ENV['AWS_ACCESS_KEY_ID'] %>
  secret_access_key: <%= ENV['AWS_SECRET_ACCESS_KEY'] %>
test:
  <<: *defaults
  bucket: <%= ENV['AWS_TEST_BUCKET'] %>
development:
  <<: *defaults
  bucket: <%= ENV['AWS_TEST_BUCKET'] %>
production:
  <<: *defaults
  bucket: <%= ENV['AWS_BUCKET'] %>

如果其他一切都失败了，您只需使用命令行参数启动rails应用程序即可。很高兴知道基本情况，你确定你的params确实传递给了你的应用程序：

ACCESS_KEY_ID = ABCDEFG SECRET_ACCESS_KEY = secreTaccessKey BUCKET_NAME = dev-images rails s

我实际上更喜欢在env中设置别名：

alias railss =＆＃39; ACCESS_KEY_ID = ABCDEFG SECRET_ACCESS_KEY = secreTaccessKey BUCKET_NAME = dev-images rails s＆＃39;

如何在rails中设置AWS凭证以进行开发？
