Ferret talk - Apr 2008 - Trunk and single table inheritance

My colleague Josh was having a hard time getting this email though  
either the web or email interfaces, so I''m forwarding it along.

Hi all,

I''m getting discrepancies between stable and trunk when doing a  
search involving single-table inheritance and I can''t locate the  
problem.

I''m running Rails 2.0.2 with the following (simplified) schema:

class Model < ActiveRecord::Base
   acts_as_ferret
end

class ModelSubClass < Model
end

Under AAF/tags/stable, Model.find_by_contents(''*'') returns all
Models
and all ModelSubClasses. Under AAF/trunk, the same query only returns  
Models. Has AAF changed its STI model?

The API also indicates that find_by_contents no longer takes  
the :models param, and including it does not change the output in  
either case -- is there a new way to search across multiple classes?  
If I could manually force the query to look at Model and all  
subclasses, I could live with the workaround.

Thanks,
Josh

Hi,

there has happened a lot in aaf trunk since the 0.4.3 was released, so
this might well be a bug I introduced recently.

I''ll look into this. Could you please file a ticket on trac?

Cheers,
Jens
