的配置Carrierwave與Amazon S3，託管在Heroku

Question

我已經按照從Carrierwave着如何在Heroku上部署使用Amazon S3的一個Rails應用程序部署說明：

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

我添加額外的行config.ru並創建config/initializers/carrierwave.rb文件，但沒有成功。

以下是carrierwave初始值設定項，其中鍵編輯。

這是正確設置？

我還需要做什麼？

任何分步指南可以幫助我實現這個目標嗎？

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 

Answer 1

您是否生成了上傳文件？

rails generate uploader Avatar

這將產生一個像這樣的文件： 應用程序/上傳/ avatar_uploader.rb 類AvatarUploader < CarrierWave ::上傳:: Base的 存儲：文件 結束

更多信息https://github.com/carrierwaveuploader/carrierwave在入門。

這是我的文件 配置/初始化/ 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 

應用程序/上傳/ 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
