Rails - Jun 2006 - Activerecord attribute without db column

Hi,

I''ve a model that is stored to the db, but just one of its atribbutes
doesn''t have a corresponding column on the table (it is used just for a
calculation and still requires validation).

I''ve been succefull by doing what is explained in
http://rails.techno-weenie.net/tip/2005/11/19/validate_your_forms_with_a_table_less_model

But I get an error of a non-existent column for the attribute I don''t
want
to store.

Any idea?

Thanks everybody

In the model, use:

   attr_accessor :attribute_name
