You should definately turn caching off:

   def cache_page?
     false
   end

When working with forms on pages, I like to use request.post? to check 
process a posted form. Here's and excerpt from a behavior I wrote for 
Ruby-Lang.org:

   def render_page
     if request.post?
       @list       = List.lookup(params[:list] || 'ruby-talk')
       @first_name = get_param(:first_name)
       @last_name  = get_param(:last_name)
       @email      = get_param(:email)
       @action     = get_param(:action).downcase
       ...
       @success = true
     else
       @success = false
     end
     super
   end
