Rails - Mar 2005 - Legacy Schema - no "id" field

Railers:

I''m new to Rails, converting some PHP apps to it.  Can anyone provide 
some pointers on where to find info for dealing with legacy database 
schemas?  Specifically, I have several tables that, for example, use 
person_id as a primary key, which is a foreign key to another table, 
but don''t have their own "id" field - will this still work
with
ActiveRecord?

Yep. Do something like this:
class XXX < ActiveRecord::Base
    has_many :persons, :class_name => "Person", :foreign_key =>
"person_id"

    def self.table_name() "YYY" end
        
    def self.primary_key()
        "myprimarykey_id"
    end
End

So, you can tell active record what the primary key is for each model, and
you can spell out what foreign keys to use for has_many and belongs_to,
etc., as well as what the table name is.
