Strategy for importing temporary .csv file?

For some reason, I’ve posted this question to this forum 4 times now
and it never appears in the daily consolidated email I get daily?
I’ve written a routine allowing the client user to declare where
their .csv import file resides and then send it to the server to
import the many rows into an existing model table, and then throw it
away.
I’ve imported many graphic files into my application using
attachment_fu and this was very straightforward as they were imported
into an existing model object. Instead, I am trying to import a file,
that when it’s processed will be ‘thrown away’. These examples are
running ok, but I won’t be able to use this strategy in my production
environment…
Here’s my view code:

<%= form_tag(:url => {:action=> “post” }, :html => { :multipart =>
true }) -%>

<%= file_field_tag "file", :size => 75, :class => "csv-input" -%>

File to Upload

<%= submit_tag -%>

Here’s my controller code:

class ImportController < ApplicationController
def aaccount_import
@owner = Owner.find(2)
n = 0
unless params[:file].nil?
fullpath = File.expand_path(params[:file]) # this doesn’t blow
up but some books say that a file object is passed and thus File
methods should apply?
FasterCSV.foreach("#{RAILS_ROOT}/convert/#{params[:file]}") do |
row|

FasterCSV.foreach(params[:file]) do |row| # cant seem to read

submitting machines full path info?

FasterCSV.foreach(fullpath) do |row|

  c = @owner.accounts.new
  c.code        = row[0]
  c.description = row[1]
  if c.save
    n += 1
  else
    n += 1
    d = Badboy.new
    d.message      = 'Aaccount Record Failed to convert'
    d.recno        = n
    d.save
  end
end

end
end
end

You’ll notice that I am able to import this file on MY OWN machine but
I’m having to HARD CODE the file path before the actual file name that
is delivered. You can see some ideas I’ve tried to make the
params[:file] behave like a FILE object and thus reveal its full path.
I am grateful for any links or suggestions.

I replied the first time round I think. params[:file] is either a
stringIO or a Tempfile, not a path to anything.
FasterCSV.new.each do |row|

end
