Your function takes one argument but your not passing it any from your view.

Hi Stephen...thanks for your help.  I''m trying to follow a books
example
(uploading a picture) and they didn''t pass any parameters in thier
view.
Rather they created an attribute in the model.  This is what I did:

My controller code:

class UploadController < ApplicationController

def get
  @description = Description.new
  end


def save
@description = Description.new(params[:description])
if @description.save
  redirect_to(:action=>''show'', :id =>@description.id)
  else
    render(:action=>:get)
    end
   end
end

My model code:

class Description < ActiveRecord::Base

  def import_strings(a_file)
  table = { }
  IO.foreach(''#{a_file}'') { |line|
    if line =~ /^ \s* " (.*?) " \s* = \s* " (.*?) "/x
      table[ $1 ] = $2
    end
  }

  description = Description.new
  description.Lenguage = [$1]
  description.Platform = [$2]
  description.save

  end

  def description=(description_field)
  self.Index_Number = [$1]
  self.Name_Of_String = [$2]

  end
end

My view model:

<h1>Importing Strings<h1>
<%= start_form_tag({:action => ''save''}, :multipart =>
true)%>
    <p>
        <b>Lenguage:</b><br/>
        <%=	select("variable", nil, @array_of_lenguages)	%>
    </p>
    <p>
        <b>Path: </b><br />
        <%= file_field ("description",
"description")%>
    </p>

    <p><%= submit_tag "Import"%></p>
<%= end_form_tag%>

I''m confused because the book uploads pictures but I want to upload 
key-values read and parsed from an incoming file.  Am I comparing two 
things totally different?  What step should I take.

thanks so much for your time
