Rails - Jan 2007 - STI with numeric keys as types

Hi,

I wish to use single table inheritance with a legacy database. The
problem is that the "type" column holds numeric keys instead of
strings
(because or performance issues blah blah...)

For example, in a table ''Components''  the value 1 in type
means that I
have a DialogComponent, 2 means ProcessComponent, ...

I''d like to have models like this :
class Component < ActiveRecord::Base; end;
class DialogComponent < Component; end;
class ProcessComponent < Component; end;

but I can''t see how to achieve this.

Thanks for your help,

Stephane.
