私は、マーチャントが自分の店の写真をアップロードできるようにするプラットフォームを開発しています。これにはCarrierwave+fogを使用しています。アプリはherokuでホストされているため、写真はAmazons3に保存する必要があります。

私のローカルマシンでは、ストレージがローカルであればすべてが正常に機能しますが、フォグがアップロードを処理すると問題が発生します。

最初にローカルストレージバージョンを投稿し（正常に動作します）、次に現在のフォグ対応のs3バージョンと発生しているエラーを投稿します。

ローカルストレージバージョン（正常に動作）：

# app/uploaders/picture_uploader.rb
class PictureUploader < CarrierWave::Uploader::Base
  storage :file
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
end

フォグ対応のs3バージョン（機能しません）：

# app/uploaders/picture_uploader.rb
class PictureUploader < CarrierWave::Uploader::Base
  storage :fog
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
end

# config/initializers/fog.rb
CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',       # required
    :aws_access_key_id      => 'xxxx',       # required
    :aws_secret_access_key  => 'xxxx'       # required
  }
  config.fog_directory  = 'yyyy'                     # required
  config.fog_public     = true                          # optional, defaults to true
end

新しいストアを作成または編集すると、画像は実際にはs3に正常にアップロードされますが、railsはアクセスが拒否されましたというエラーメッセージを表示します（app / tmp /carrierwave/20121104-0929-5512-8270/04.pngにアクセスできませんでした） 。

app / tmp /carrierwave / 20121104-0929-5512-8270 / 04.pngをブラウザに直接入力すると正常に機能するため、このエラーは私を混乱させます。

完全を期すために、ここにコントローラーとモデルがあります（両方のバージョンで同じ）

#stores_controller.rb
def create
  @store = Store.new(params[:store])

  respond_to do |format|
    if @store.save
      format.html { redirect_to @store, notice: 'Store was successfully created.' }
      format.json { render json: @store, status: :created, location: @store }
    else
      format.html { render action: "new" }
      format.json { render json: @store.errors, status: :unprocessable_entity }
    end
  end
end

#models/store.rb
class Store < ActiveRecord::Base
  mount_uploader :bild, PictureUploader
end

アップローダに cache_dir を追加してみてください:

  def cache_dir
    "#{Rails.root}/tmp/uploads"
  end

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

また、config/initializers/carrierwave.rb を追加する必要があるかもしれません:

CarrierWave.configure do |config|
    # hack fix for windows machine due to tmp file permission error
    # per https://github.com/jnicklas/carrierwave/issues/220/
    if ENV['RAILS_ENV'] != 'production'
      config.delete_tmp_file_after_storage = false  
    end
    config.fog_credentials = {
      :provider               => 'AWS',       # required
      :aws_access_key_id      => ENV['MF_S3_KEY'],       # required
      :aws_secret_access_key  => ENV['MF_S3_SECRET'],       # required
      :region                 => 'us-east-1'  # optional, defaults to 'us-east-1'
    }
    config.fog_directory  = ENV['MF_FLYER_BUCKET']                     # required
    #config.fog_host       = 'https://assets.example.com'            # optional, defaults to nil
    #config.fog_public     = false                                   # optional, defaults to true
    #config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}  # optional, defaults to {}
