Rails - Jul 2006 - code for uploading files to the filesystem instead of db

Does anyone have any standard code for uploading files to the 
filesystem?

I''ve got code already for uploading images to the database but
I''d
prefer to store the files on the filesystem.

In particular I need to know how to

(a) ensure a file has been selected in the file_field
(b) how to extract the filename from the file_field
(c) how to actually move the file from client to server

Problem is this requires RMagick - I can''t seem to get this to work on 
my machine - don''t know why.
My production server arrives tomorrow so I can try again with that.

Don''t suppose anyone has a solution that doesn''t need any
other plugins?

Only to resize images.

For anyone who is interested, I found this really simple way of 
uploading a file to the filesystem without the need for any plugins or 
any complicated code.  Takes 10 minutes to get it going.

Not too hard

  #view
  <%= form_tag({:action => ''upload''}, {:multipart =>
true}) %>
    <%= file_field_tag ''my_file'' %>
  <%= end_form_tag %>

  #controller
  def upload
    file = params[:my_file]
    if file.size > 0
      File.open("#{RAILS_ROOT}/some/dir/#{file.original_filename}", 
''w+'') do |f|
        f.write(file.read)
      end
    end
  end

a) "file.size > 0" tests whether or not there a file was actually 
uploaded
b) "file.original_filename" retrieves the name of the file
c) the directory location provided to File.open is where the uploaded 
file will be written.

Just make sure permissions are set properly in the directory you are 
uploading to and that should be all you need.
