saving ActiveRecord/Form data changes??

Greetings everyone,

This post has been moved (on suggestion) from the Ruby forum.

I can't pass updated/changed values from the form elements to the
ActiveRecord. However something is going through because the table's
update_when column is registering the date/time of the update, but
otherwise no data revisions to other columns transpire. Have tried
using form_for helper as well, but the same results.

This is all new to me, so not sure what additional info will be
relevant. But am using Ruby 1.8.6 with a local MYSQL 5.1 database thru
a Radrails IDE. My apologies for whatever info I have ommitted. Any
suggestions on where I have gone astray will be most appreciated.

Thanks, Bill


class FileController < ApplicationController

def edit
    @file = File.find(params[:id])

def update
    @file = File.find(params[:id])
    if @file.update_attributes(params[:file])
        redirect_to :action => 'show', :id => @file
        render :action => 'edit'


<% form_tag (:action => 'update', :id => do %>

<p><label for="file_description">Description</label><br>
<%= text_area 'file', 'description' </p>

<%= submit_tag 'Save changes' %>
<% end %>

<%= link_to 'Back', {:action => 'list'} %>
