Rails - Jun 2008 - How to extract the path at the view, or how to know who is calling the polymorph?

Hi,

I have addresses as a polymorphic,
it includes adressable_type and addressable_id

in my routes I have

map.resources client do |c|
    c.resources :addresses
end

and
map.resources users do |u|
    u.resources :addresses
end

(and many more that have addresses)

I have an ajax form to add addresses
but the way I have it is not very nicely styled,

at the end of the form, I submit it with 

        <%=	button_to_remote("Add Address",
			:submit	 => "address_form",
			:url     =>  client_address_path(@client.id), :method =>
''post''
			)
	%>

but Instead of the url line to be hard-coded, I
I''d like the url line to be inflected from the context on which the
form
was called,
(client or user)

I am reading through the api, but I can''t find how to extract the path
and convert it on its components,
any hint on whether there''s a rails method built for it,
or which approach to take is appreciated,

Thank you,

Andres
