ruby-on-rails - 未初始化常量 AWS::S3::Base

Question

我在 lib 文件夹中有这段代码。这段代码在 rails 之外工作，但是当它从 rails Controller 调用时，我得到未初始化的常量 AWS::S3::Base 错误

require 'rubygems'
require 'aws/s3'

module S3Util

  def self.upload_file(local_file)
    mime_type = "application/octet-stream"
    bucket = "test"

    AWS::S3::Base.establish_connection!(
      :access_key_id     => '*****',
      :secret_access_key => '****'
    )

    base_name = File.basename(local_file)

    puts "**** Uploading #{local_file} as '#{base_name}' to '#{bucket}'"

    AWS::S3::S3Object.store(
      base_name,
      File.open(local_file),
      bucket,
      :content_type => mime_type
    )

    puts "***** Uploaded!"

  end
end

Answer 1

在你的 Controller 中做

require 'aws/s3'

及其对我的工作
