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


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

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

(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(, :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,
