The usual trick in situations like this is to use a thread-local variable, set in the controller action and accessed from the models. It's a somewhat leaky abstraction, but probably the most reliable way to do things (ActiveSupport uses it for the Time.zone stuff). The code would look like (sketch):
in application_controller.rb (or elsewhere): before_filter :set_customer_db def set_customer_db Thread.current[:customer_db] = ... end I can't think of how exactly you'll end up accessing it in the models, but the magic_multi_connections gem should provide some guidance. --Matt Jones On Nov 2, 8:09 am, jmamma <jackli...@gmail.com> wrote: > Thanks Amar.
