Rails - Oct 2005 - Setting a checkbox that doesn't correspond to model data

I have a login form with a ''remember me'' checkbox.
The checkbox is purely functional, i.e. doesn''t correspond to model
data.
The following code works but doesn''t seem very elegant:

[view code]
  <p><label for="user_remember_me">Remember
me</label><br/>
  <%= check_box(''remember_me'',
''not_used'', {}, "yes", "no")
%></p>

[controller code]
  if params[:remember_me][:not_used] == ''yes''
    # TODO: set cookie
  end

I just want to signal a flag to the controller and I don''t need the 2nd
check_box parameter.  Can anyone suggest a cleaner way to code this?
