Thanks for the reply. I'm sure I can make it work with an SQL query, but I'm new to Cake and I'm trying to work within the system :)
Is there a way to make this complex a query work with conditions on find(), paginate(), etc, or will I need to resort to writing custom queries? ~Ryan On Mar 29, 11:18 am, John Andersen <j.andersen...@gmail.com> wrote: > You have to use the table alias for the schools table!
