Jesse,
Af few weeks ago, I asked a question about a snazzy way to do a fill
in form in one line
return
$self->fill_form($self->tt_process({}),$self->dbh->selectrow_hashref("SELECT
* from menus WHERE id = ?",{},$id));
Since this uses dbh directly, in Krang to do something similar does
that mean you would make a method in a Krang module that was simply a
wrapper to this call ? I guess the advantage to that would be that
many other places could call this method with common results, instead
of having to change many sql statements and risking errrors.
Jeff.
