phanks:

post '/upload' do
unless params[:file] &&
(tmpfile = params[:file][:tempfile]) &&
(name = params[:file][:filename])
@error = "No file selected"
return haml(:upload)
end
directory = "public/files"
path = File.join(directory, name)
File.open(path, "wb") { |f| f.write(tmpfile.read) }
end

so will be better for me :)

OK. Beware that f.write(tmpfile.read) will use as much RAM as the size
of the attachment. Hence the suggestion to read it in and write it out
in blocks of, say, 64K.
