霧S3上傳導致

Question

我正在開發一個平臺，允許商家上傳他們的商店圖片。我正在使用Carrierwave +霧。由於該應用程序託管在heroku上，圖片需要存儲在亞馬遜S3上。

在我的本地機器上，如果存儲器是本地的，一切正常，但霧處理上傳時出錯。

我將首先發布本地存儲版本（正常工作），然後是我目前支持霧的s3版本以及我正在獲取的錯誤。

本地存儲的版本（正常工作）：

# 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 

啓用霧-S3版本（不工作）：

# 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 

現在當我創建或編輯一個新的商店，畫面實際上已經成功上傳到s3，但Rails給出了Permission denied錯誤消息（app/tmp/carrierwave/20121104-0929-5512-8270/04.png無法訪問）。

這個錯誤讓我困惑，因爲在應用程序的/ tmp/carrierwave輸入/ 20121104-0929-5512-8270 /直接04.png到瀏覽器工作正常。

爲了完整起見，這裏是控制器&模型（同樣在兩個版本）

#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 

Answer 1

嘗試增加的cache_dir您上傳：

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 

此外，您可能有添加配置/初始化程序/ carrierwave.rb：

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 {}
