How to sort columns from more than one table using Ajax?

some code would help. can you show e.g. the controller? generally i
would say you have to include the table name in the property to sort
by, e.g.

@events = Event.find(:all, :include => :location, :order =>

so "" (or "location.name_reverse") would be the param in
the sort link to sort by location name.

i'm just guessing here what the problem might be, as i said show some
code that might clear things up.
