Rails - Jun 2006 - Parent Child form using Partials

I am trying to make a simple application which consists of contacts and 
their addresses.

class Contact < ActiveRecord::Base
  has_many :addresses
end

class Address < ActiveRecord::Base
  belongs_to :contact
end

I would like to be able to edit/add addresses from within the edit/add 
of the contact.  I scaffolded the contact and address objects and 
modified the contacts/_form partial as follows:

<%= error_messages_for ''contact'' %>

<!--[form:contact]-->
<p><label for="contact_name">Name</label><br/>
<%= text_field ''contact'', ''name'' 
%></p>
<%= render :partial => ''addresses/form'', :collection
=>
@contact.addresses %>
<!--[eoform:contact]-->

The addresses/_form partial looks like this:

<hr />
<%= error_messages_for ''address'' %>

<!--[form:address]-->
<p><label for="address_line_1">Line
1</label><br/>
<%= text_field ''address'', ''line_1'' 
%></p>

<p><label for="address_line_2">Line
2</label><br/>
<%= text_field ''address'', ''line_2'' 
%></p>

<p><label for="address_city">City</label><br/>
<%= text_field ''address'', ''city'' 
%></p>

<p><label
for="address_state">State</label><br/>
<%= text_field ''address'', ''state'' 
%></p>

<p><label for="address_zip">Zip</label><br/>
<%= text_field ''address'', ''zip'' 
%></p>
<!--[eoform:address]-->

I am running into to issues with this design.  1)  I''ve manually added 
address objects into the table and when i go to addresses/edit/1, it 
renders the two addresses but the fields are blank.  Like it sees the 
records, but its not getting put into the partial.  2)  After I get the 
addresses displayed, how would I go about saving the contact and all of 
the addresses in a single post-back?

I''ve been googling for days, and it seems this should be a simple thing
that has been encountered before.

Thanks in advance for your help!

Additionally, in my contacts_controller.rb ''edit'' method, I
have the
following to include the address information

def edit
  @contact = Contact.find(params[:id], :include => :addresses)
end

In case someone else stumbles along this post, I have found a plugin and 
a generator that might fit my needs.  Since RubyForge is down, I
haven''t
been able to download and install.  I will update with what I find.

Anyone trying to accomplish this should check out the Sub-List form 
plugin (link above).  Solves my issue and works great!
