Rails - Dec 2005 - globally affecting pluralization AND primary_key for all models

i know ActiveRecord::Base has a hook to affect pluralization on/off...  but i
couldn''t find one for affecting the primary key?  i have a database
with about
30 tables of the form

   create table foo (
     foo_id serial,
     ...
   );

and didn''t want ot have to edit every generated model so i used:

   class ActiveRecord::Base
     def self::inherited other
       ret = super
       other.table_name = other.table_name.singularize
       other.primary_key = "#{ other.table_name }_#{ other.primary_key
}"
       ret
     end
   end

in environment.rb

and thus

   ./script/console
   >> Foo.table_name
   => "foo"
   >> Foo.primary_key
   => "foo_id"

works for all tables.  is there a cleaner way to do this?

regards.

ActiveRecord::Base.primary_key_prefix_type = :table_name_with_underscore

Don''t ask me where to find that either, I found that little nugget in
the rails book :)

cool.  saw that here

   >> ActiveRecord::Base.methods.grep /key/
   => ["primary_key_prefix_type",
"primary_key_prefix_type=", "set_primary_key_prefix_type",
"reset_primary_key", "primary_key",
"primary_key=", "set_primary_key"]

but didn''t know what the args were and the doc site was down attm...

thanks!
