Can't read an uploaded file with Ruby's Framework Padrino -


i have form uploading files:

-# coding: utf-8 - content_for(:body_classes, "body3") .content   - form_tag url(:images, :create), :method => :post, :multipart => true     = file_field_tag :file     = submit_tag "upload"

and controller handle it:

fbapp.controllers :images    :new     render 'images/new'   end    post :create     require 'net/ftp'     file = params[:file]     ftp = net::ftp.new('xxx.xxx.xxx.xxx')     ftp.passive = true     ftp.login('user','pass')     ftp.storbinary("stor " + "original_filename", stringio.new(file.read), net::ftp::default_blocksize)     ftp.quit   end end

and every time try upload file "internal server error". , log has this:

nomethoderror - undefined method `read' #<hash:0x00000003697780>:

i'm trying on heroku way. can't figure out what's problem... seems work lot of people me.

you should use:

file = params[:file][:tempfile]

and suggest retrieve filename

name = params[:file][:filename]
