textfile upload

I am having trouble finding things online on how to do a simple file upload. Could you guys give me some advice? Point me in right direction.

Hi, I posted a similar question quite recently, as all the tutorials I found online were incorrect.

I have some basic code that works for uploading files, which I have pasted below. It has no error checking of any kind at the moment.

Hope it helps, Jen.

Model:

class DataFile < ActiveRecord::Base #takes the upload object and extracts the file. def self.save(upload)      name = upload['upload'].original_filename      directory = "public/data/upload"      # create the file path      path = File.join(directory, name)      # write the file      File.open(path, "wb") { |f| f.write(upload['upload'].read) } end

Controller: class UploadController < ApplicationController def index #Renders a fiew for the user. render 'upload.rhtml'    end    def create #posts to the data model.      post = DataFile.save(params[:upload]) puts "file uploaded" render 'upload'    end end

View: <h1>File Upload</h1> <% form_for(:upload, :url=>{ :controller=>"upload", :action=>"create"}, :html => {:multipart => true}) do |f| %> <%= f.label :"File to upload" %> <%= f.file_field :upload%> <%= f.submit %> <% end %>
