如何同时上传多张照片？ Ruby on Rails

Question

i have a problem with upload photos.

In muy view, i take some photo as below:

<%= f.label :images_urls, 'image' %> <br>
    <%= f.file_field :images_urls, {:multiple => true} %> <br>

But I don't know how save them in controller to my model "Furniture". This is my furniture, but i don't work:

 def create
    image_io = params[:furniture][:images_urls]
    File.open(Rails.root.join('public','furnitures', image_io.original_filename), 'wb') do |file|
      file.write(image_io.read)
    end

    @furniture = Furniture.create(params[:furniture])

    redirect_to admins_path
  end

Have you any suggestion??

Thank you very much

I would suggest using a gem such as Carrierwave or Paperclip . In your view, to allow multiple file upload, you may need to implement asynchronous file upload. A very handy way to do this that uses jQuery is a plugin called jQuery-file-upload (which can handle multiple files).

Ryan Bates has an excellent video on Railscasts jQuery File Upload on how to do this. There's also a gem that prepackages this jQuery plugin for you, called jquery-fileupload-rails .
