使用Amazon S3配置Carrierwave,在Heroku上托管

Question

我遵循了Carrierwave的部署说明,了解如何使用Amazon S3在Heroku上部署Rails应用程序:

https://github.com/carrierwaveuploader/carrierwave/wiki/How-to%3A-Make-Carrierwave-work-on-Heroku

我已将额外的行添加到config.ru并创建了config/initializers/carrierwave.rb文件,但没有成功.

下面是carrierwave初始化程序,其中包含密钥.

这是否正确设置？

我还需要做什么？

任何分步指南,以帮助我实现这一点？

CarrierWave.configure do |config|
config.fog_credentials = {
:provider               => 'AWS',                        # required
:aws_access_key_id      => REDACTED,                     # required
:aws_secret_access_key  => REDACTED,                     # required
:region                 => 'eu-west-1',                  # optional, defaults to 'us-east-1'
:host                   => 's3.example.com',             # optional, defaults to nil
:endpoint               => 'https://s3.example.com:8080' # optional, defaults to nil
}
config.fog_directory  = 'myawsbucket'                  # required
config.fog_public     = false                                   # optional, defaults to true
config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}  # optional, defaults to {}
end

你是否生成了上传者文件？

rails generate uploader Avatar

这将生成如下文件:app/uploaders/avatar_uploader.rb class AvatarUploader <CarrierWave :: Uploader :: Base storage:file end

更多信息https://github.com/carrierwaveuploader/carrierwave入门.

这是我的文件config/initializers/carrierwave.rb

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => 'REDACTED',
    :aws_secret_access_key  => 'REDACTED'
  }
  config.fog_directory  = "myawsbucket"
end

应用程序/上传/ amazon_uploader.rb

class AmazonUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick

  include Sprockets::Helpers::RailsHelper
  include Sprockets::Helpers::IsolatedHelper

  storage :fog

  include CarrierWave::MimeTypes
  process :set_content_type

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  version :user_thumb do
    process :resize_to_limit => [200, 200]
  end

  def extension_white_list
    %w(jpg jpeg gif png)
  end
end
