Problems about uploading file

Hi guys,
I am working on some upload file code , here it is :
================== code begin =================
require ‘fileutils’
require ‘uuid’
class Content < ActiveRecord::Base
include FileUtils
include UUID
before_create :write_file_to_disk
before_update :write_file_to_disk

.........              ................

def update_attributes_from_params params, *args
  args.each do |attribute|
    s= params[attribute].blank?  ?  "self.#{attribute.to_s}=%Q{}"

:

            %Q{self.#{attribute.to_s}="#{params[attribute]}"}
    eval(s)
  end
  update
end

… …

private

def write_file_to_disk
   file_path = "#{upload_file_path}/#{user_id}/#{file_name}"
   p " the file size : #{file.size}"
    File.open(file_path, "wb") do |media_file|
        media_file.write  file.read
    end
    self.size = @file.size
end

def file= file
   return  if file.blank?
    @file = file
  ext_name = File.extname file.original_filename
 # original_file_name and file_name are both content attributes
    original_file_name = file.original_filename
  file_name =  UUID.new + ext_name
end

end

when I update an file, I do it like this :
@content = Content.find params[:content_id]
@content.update_attributes_from_params params, :title,
:orginazation, :file

and it produces :
“the file size : 8477823”

but when I check the file uploaded ,
irb >>
File.size"/home/tim/upload_test/1/adb12d60-9bd5-012a-a458-000c29f18cec.mp3"
=> 2176
it’s only 2.1K, so any body can tell me why and how to handel it
correctly.
I tried @content.send(“file=”,params[:file]),but the real size is
still 2176.

Thanks, regards!

                          Tim

It looks like you’re using Rails, in which case you might save
yourself some work with the attachment_fu plugin:

http://svn.techno-weenie.net/projects/plugins/attachment_fu/

And if you are using Rails you’ll probably receive more responses on
the Rails mailing list:

http://groups.google.com/group/rubyonrails-talk

Sorry not to have answered your question directly!
