I have a problem I can't seem to find an answer to.  I have the
following relations

(contact) 1 == *(Phone) *== (Phone Type).
(contact) 1 == 1 (Address)

I will be constructing an AJAX interface that allows user to add
multiple rows to the contact.  As such, I want to make it possible to
get them from the request.  I have the following for contact and
address, which works

@company_contact = CompanyContact.new(params[:company_contact])
@address = Address.new(params[:address])
@company = Company.find(params[:company])

@company_contact.company = @company
@company_contact = @address

#TODO phones.

How do I get the phones to work?  I've tried the following.

  @phones = Phone.new(params[:phones])

but it doesn't return anything, just nill.  My embedded form looks
like this.

<h2>Phones</h2>
<table>
<% for phone in @phones do%>
<tr><td>Number:</td><td> <%= text_field("phone" , "number") %></td>
<td><%= get_phone_types %></td></tr>
<% end %>
<table>

and my call to the template looks like this

<%= render (:partial => "shared/formphone", :object => @phones =
@company_contact.phone()) %>


When I look at the HTML it just generates the following

<tr><td>Number:</td><td> <input id="phone_number" name="phone[number]"
size="30" type="text" /></td> <td><select id="phone_phone_type_id"
name="phone[phone_type_id]"><option value="3">business</option>

<option value="4">fax</option>
<option value="2">home</option>
<option value="1">mobile</option></select></td></tr>

<tr><td>Number:</td><td> <input id="phone_number" name="phone[number]"
size="30" type="text" /></td> <td><select id="phone_phone_type_id"
name="phone[phone_type_id]"><option value="3">business</option>
<option value="4">fax</option>
<option value="2">home</option>
<option value="1">mobile</option></select></td></tr>

<tr><td>Number:</td><td> <input id="phone_number" name="phone[number]"
size="30" type="text" /></td> <td><select id="phone_phone_type_id"
name="phone[phone_type_id]"><option value="3">business</option>
<option value="4">fax</option>
<option value="2">home</option>
<option value="1">mobile</option></select></td></tr>

<tr><td>Number:</td><td> <input id="phone_number" name="phone[number]"
size="30" type="text" /></td> <td><select id="phone_phone_type_id"
name="phone[phone_type_id]"><option value="3">business</option>

<option value="4">fax</option>
<option value="2">home</option>
<option value="1">mobile</option></select></td></tr>

As you can see, all the input fields are the same.  Is there a way I
can make them unique, as well as easily get them from the request?
Any help would be greatly appreciated!

thanks,
Todd
