Fallback for partial_paths on rendering process

Hi, I have an application that uses single table inheritance.
Very simple stuff:
   class Place < ActiveRecord::Base
   class City < Place

lets say I have a City on the @place
whenever I try using the

render @place

I will get an error, saying the templace cities/city doesn't exist
but I do have a places/place template.

Is the any nice way to add this fallback for the base_class on these
cases?

Also in search, I have collections with several types of items
so I'd have to manually render each item using class.base_class.name
to force using place instead of city
when rendering the item

Is that the best/only solution?

Thanks
