Ian-
I don't know how you would do that in the way you are describing. One
possibility though would be to do this:
map.resources :sons, :controller => "papas"
map.resources :daughters, :controller => "papas"
This will point both routes to the papas controller. You won't see
"sons" or "daughters" come through as params. But you can query
request.env['REQUEST_URI'] and you would get back something like '/
sons/new/'.
So:
1. request.env['REQUEST_URI'].split("/") will give you an array
["","sons","new"]
2. access [1] of the array and you will have your parameter.
A little convoluted but I think that it would do what you want.
