Hi to all,

someone can tell me if are there some ways to map STI model into a  
resource map ? (restful)

I cannot figure out how to implement a single controller/views to handle  
STI resources…

Ex.:

Model : Category =\> type(s) =\> CategoryEvent, CategoryCalendar, and so  
on…

I want to have a single restful controller ex. categories handling all  
category types in some ways:

ex.

List all category of type Calendar: /categories/CategoryCalendar  
New category of type Event: /categories/new/CategoryEvent

I cannot figure out how to map map.resource…, maybe passing a type  
parameter? but doing so it’s not beautiful:

/categories?type=CategoryCalendar  
/categories/new?type=CategoryEvent

Someone can help me ?

Thanks a lot…
