Resources are single-item things. REST does not address the issue of a
transaction spanning multiple items. So you can either attach it
arbitrarily to one member, in which case the "from" member above is
logical, or you can attach it at a higher level such as
"/accounts/transfer". In either case, you can use one of the resource
arguments to create the extra methods.
map.resource("account", "accounts", member={"deducts": "POST"})
This would create a route to your URL above. You'd have to define the
"deducts" action method yourself; "paster restcontroller" isn't smart
enough to do that.
I use this to create an "ask_delete" URL for a delete confirmation form.
