Question

我试图从Rails表单中附加的Paperclip文件中保存absolute_path。我想将它保存到数据库中供以后使用。

我通过Paperclip文档阅读，无法找到我认为可行的任何内容。 Ruby在ruby-docs中有一个文件抽象解决方案，我可以在终端中工作，但我不确定如何使用Rails和Paperclip在表单中实现它。

最终，目标是解析XML文件并使用文件路径告诉Paperclip在哪里可以找到XML中列出的位于同一文件夹中的图像。

我有2个型号BulkImport和BulkDownloads。 BulkImport解析xml文件并在BulkDownloads中创建每个下载。

XML剪辑：

<?xml version="1.0"?>
<CUSTOMERS>
     <CUSTOMER>
          <FIRST_NAME>FIRST</FIRST_NAME>
          <LAST_NAME>LAST</LAST_NAME>
          <EMAIL>TEST@TESTEMAIL.COM</EMAIL>
          <CUSTOMER_ID>222222</CUSTOMER_ID>
          <WEB_PASSWORD>1234567</WEB_PASSWORD>
          <GALLERY_CODE>CODE</GALLERY_CODE>
     </CUSTOMER>
</CUSTOMERS>

BulkImports模型：

class BulkImport < ActiveRecord::Base
  require "open-uri"
  has_many :bulk_downloads, dependent: :destroy

  has_attached_file :doc
  validates_attachment_content_type :doc, 
                                presence: true,
                                content_type: ["application/xml", 
                                               "text/xml"],
                                message: "file must be in xml file format"

  def parse_file
    tempfile = File.open("#{doc.path}")
    file = Nokogiri::XML(tempfile)
    parse_xml(file)
  end

  def parse_xml(file)
    file.root.elements.each do |node|
       if node.node_name.eql? 'CUSTOMER'
         tmp_download = BulkDownload.new
         tmp_download.cust_id = node.xpath("CUSTOMER_ID").text
         tmp_download.webpassword = node.xpath("WEB_PASSWORD").text
         img = node.xpath("CUSTOMER_ID").text
         ## THIS IS THE PATH I WANT TO CUSTOMIZE BASED ON XML FILE LOCATION
         image_url = URI.parse("app/xml/#{img}.jpg").to_s
         tmp_download.attachment = open(image_url)
         tmp_download.save!
         self.bulk_downloads << tmp_download
       end
       save
    end
  end
end

BulkImport控制器创建操作：

def create
   @bulk_import = BulkImport.new(bulk_import_params)

   respond_to do |format|
     if @bulk_import.save
       @bulk_import.parse_file
       format.html { redirect_to bulk_imports_path, notice: "#{@bulk_import.bulk_downloads.count} downloads were successfully created." }
       format.json { render :show, status: :created, location: @bulk_import }
     else
       format.html { render :new }
       format.json { render json: @bulk_import.errors, status: :unprocessable_entity }
     end
   end
 end

我在save之前尝试过queued_for_write [：original] .path，它返回xml doc的tmp文件路径而不是原始url。

2.2.1 :007 > doc = bi.doc.queued_for_write[:original]
=> Paperclip::FileAdapter: testfile.xml
2.2.1 :008 > doc.path
=> "/var/folders/b_/6d4jhyxn0yd9mvv2bzvc67nw0000gn/T/9bc955dbd052ef51652e70a5104492e320150629-38408-m0q0zm.xml"

来自表单的Rails / Paperclip absolute_path？
