Hi guys, I've been lurking around the RORO list for a while. I don't
know whether it's appropriate to ask rails tech questions here, but I'll
post anyway and see what happens...
My question is: if I subclass a model, how do I limit the records
retrieved in the subclass?
eg I have:
> % gem list --local | egrep 'rails|activerecord'
> activerecord (1.15.3)
> rails (1.2.3)
>
> class Location < ActiveRecord::Base
> # stuff
> end
>
> class InnerCity < Location
> # additional stuff
> end
In the InnerCity class, I only want to see the rows that would result
from a where clause of "postcode in (2000,2001)". How would I do this?
I know about polymorphism and :polymorphic and :as (and that would be
the ideal solution). But I'm wondering is there's another way...
Thanks,
