<guess factor=blind>
maybe plug items into the NEW pseudorecord...?
similar to a CREATE RULE type of thing?

create rule
add_rec
as on insert to my_view
do instead
insert into my_table (
fullname,
yadayada
) values (
NEW.lastname || ', ' || NEW.firstname,
NEW.something / NEW.somethingelse + NEW.theotherthing
);

</guess>
