Rails - Dec 2007 - Nested resources form_for problem

Hi,

I have a resource map like this:

  map.resources :users do |user|
    user.resource :sreg10record
  end

So a User is supposed to have (at most) one Sreg10record. The problem
is in the views. I tried following this tutorial:
http://www.akitaonrails.com/2007/12/12/rolling-with-rails-2-0-the-first-full-tutorial
which proposes something like:

<% form_for( [@user, @sreg10record] ) do |f| %>

However, doing that yields "undefined method `has_key?'' for
#<Sreg10record:0xb6f47bc4>". So I tried

<% form_for( [:user, @sreg10record] ) do |f| %>

as intended for namespaced resources, however that causes the ID of
the record to be used in the URL, which then causes the controller to
fail when retrieving @user. Experiments with url_for (which appears to
be used by form_for anyway) or user_sreg10record_url(@user) failed in
more or less entertaining ways too. So, how do I make form_for
generate a valid path like "/users/<user_id>/sreg10record"?

A small addition: when using

<% form_for( user_sreg10record_url(@user) ) %>

the generated URL is apparently right, but all form fields are left
empty. Submitting the form ends up somewhere where "Only get requests
are allowed." In the form, there''s a happy mixture of the
user''s ID
and the record''s ID.
