Hi,
I am trying your solution like this
My model is like this:-
"
before_validate :cache_rating
define_index do
    indexes :name,:sortable => true
    indexes cached_rating, :as=>:property_rating
 end
def cache_rating
    self.rating
 end
"
Whenever I am trying to rebuild the indexing using "rake ts:rebuild",
I am getting error "undefined method `before_validate' for #<Class:
0xb6cce9c4>"

Can anyone help me out.

Thanks,
Mike
