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,
