ruby-on-rails - Rails4.1 : AWS errors missing region

Question

我正在尝试使用回形针、aws-sdk gem 和 Amazon S3 创建图像 uploader 。我收到此错误:

Aws::Errors::MissingRegionError in ProjectsController#create. 
Missing region; use :region option or export region name to ENV['AWS_REGION']. using Oregon region. 

projects_controller.rb

def create
    @project = current_user.projects.new(project_params)
    @project.save
    respond_with(@project)
end

application.rb 文件

config.paperclip_defaults = {
        storage: :s3,
        s3_host_name: "s3-us-west-2.amazonaws.com",
        s3_credentials: {
            bucket: ENV['AWS_BUCKET'],
            access_key_id: ENV['AWS_ACCESS_KEY_ID'],
            secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
        }
    }

根据我了解的 S3 文档，我需要更改为 ENV['AWS_REGION']

config.paperclip_defaults = {
        storage: :s3,
            region: "ENV['AWS_REGION"],
        s3_credentials: {
            bucket: ENV['AWS_BUCKET'],
            access_key_id: ENV['AWS_ACCESS_KEY_ID'],
            secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
        }
    }

并将区域添加到我的 .env 文件

export AWS_BUCKET=realv1
export AWS_ACCESS_KEY_ID=<MY_ACCESS_KEY_ID_HERE>
export AWS_SECRET_ACCESS_KEY=<MY_ACCESS_KEY_HERE>
export AWS_REGION="'us-west-2'

我重新启动了服务器并重新测试，但仍然出现相同的错误。

更新

更新:

在 Rails 控制台中

2.0.0p247 :001 > ENV["AWS_REGION"]

=> "us-west-2"2.0.0p247 :002 >

错误源自 Paperclip gem。在您的 config.paperclip_defaults 中，您在本应使用 s3_region 时使用了 region。这是配置的外观:

config.paperclip_defaults = {
  :storage => :s3,
  :s3_region => ENV['AWS_REGION'],
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
}
