Conceptual help needed for controllers that work with ajax requests

Hi,

got a problem,
I have a polymorphic object, “phone” that is created via remote
(ajax),
then refreshes the client_phones div id,

But what if I need to call Phone.create from different models,
and refresh e.g. the user_phones div id

How do you handle rendering partials that need data generated from a
controller different than the one calling the template?

Thanks,
