Question

我使用Carrierwave file upload上传和下载文件。我的模特：

class InvoiceDetail < ActiveRecord::Base
    mount_uploader :attachment, AttachmentUploader
  validates :invoice_number, :supplier_name, :attachment, presence: true    
  validates_uniqueness_of :invoice_number
end

附接/ uploader.rb：

 def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def filename

“＃{model.invoice_number}。＃{file.extension}”if original_filename.present？端

invoice_detail / _form.html.erb：

<%= form_for(@invoice_detail , html: {class: 'form-horizontal', role: 'form' }) do |f| %>

    <div class="field">
        <%= f.label :invoice_number, :class => 'control-label' %>
            <div class="controls">
    <%= f.text_field :invoice_number, :class => 'text_field' %>
  </div>
  </div>
    <div class="field">
    <%= f.label :supplier_name, :class => 'control-label' %>
                <div class="controls">

    <%= f.text_field :supplier_name, :class => 'text_field' %>
    </div>
  </div>

     <div class="control-group">
      <%= f.label :attachment , :class => 'control-label' %>
      <div class="controls">
        <%= f.file_field :attachment, :class => 'file_field' %>
      </div>
    </div>
  <div class="form-actions">
    <%= f.submit "Create Invoice Details", :class => 'btn btn-primary' %>
    <%= f.submit "cancel", :class => 'btn btn-danger', method: :delete, data: { confirm: 'Are you sure you want to cancel' } %>

  </div>
<% end %>

目前的代码在单个文件上传时运行良好。现在我的要求是存储多个文件（多个文件上传），当我点击下载时，所有同一个ID下的多个文件都必须压缩和下载。

Answer 1

请点击multiple upload链接进行多次上传。并且为了以zip格式下载文件，最好的方法之一是使用rubyzip gem。

如何实现多文件上传以及如何使用carrierwave rails下载具有相同id作为zip的文件？
