Rails 5霧CarrierWave照片上傳到亞馬遜S3沒有隱含的字符串轉換爲陣列

Question

我是一個絕對的初學者的Ruby on Rails。 我遇到了一個錯誤，我不知道該如何處理。

我想做什麼：將照片上傳到Amazon S3存儲桶。

錯誤：沒有將數組隱式轉換爲字符串。

的錯誤出來時，@ prototype.save原型＃未能在prototypes_controller.rb創建行動

問：爲了解決這個問題，時候正是我應該轉換數組字符串？

顯示在Webrick服務器中的參數。

{"utf8"=>"✓", 
"prototype"=> 
    {"name"=>"dafda", 
    "prototype_images_attributes"=> 
     {"0"=> 
     {"content"=> 
      #<ActionDispatch::Http::UploadedFile:0x007fe07491b778 
      @content_type="image/jpeg", 
      @headers="Content-Disposition: form-data; name=\"prototype[prototype_images_attributes][0][content]\"; filename=\"card100002057_1.jpg\"\r\nContent-Type: image/jpeg\r\n", 
      @original_filename="card100002057_1.jpg", 
      @tempfile=#<File:/var/folders/yy/42bpgmdj4t16rf0_5xsly3tc0000gp/T/RackMultipart20170815-70968-fzdoey.jpg>>, 
     "status"=>"main"}, 
     "1"=>{"status"=>"sub"}, 
     "2"=>{"status"=>"sub"}}, 
    "catchcopy"=>"fdafda", 
    "concept"=>"fdafda"}, 
    "commit"=>"Publish"} 

以下是可能與錯誤有關的文件。

prototype_controller.rb

def create 
    @prototype = current_user.prototypes.new(prototype_params) 

    if @prototype.save 
    flash[:notice] = 'Prototype was successfully created.' 
    redirect_to root_path 
    else 
    flash[:alert] = 'Prototype was not successfully created.' 
    render :new 
    end 
end 

private 
def prototype_params 
    params.require(:prototype) 
    .permit(:name, 
      :catchcopy, 
      :concept, 
      prototype_images_attributes: [:content, :status] 
    ) 
end 

def set_prototype 
    @prototype = Prototype.find(params[:id]).decorate 
end 

prototype_image_uploader.rb

    storage :fog 

    def store_dir 
    'uploads' 
    end 

    def extension_whitelist 
    %w(jpg jpeg gif png) 
    end

CarrierWave.configure do |config| 
    config.storage = :fog 
    config.fog_credentials = {

如果有人遇到下面的錯誤，你能給我一些線索嗎？ 任何意見將不勝感激！提前致謝！

Answer 1

，我建議你到裏面添加CarrierWave.configure塊下面幾行：

config.ignore_integrity_errors = false 
    config.ignore_processing_errors = false 
    config.ignore_download_errors = false 

它可以幫助獲得更多的理解錯誤。
