I did have it set up that way at one point. it worked quite nicely as
long as I made the singleton in a subclass of the main Factory (which
might be shared by several applications with different configurations).
i gave up on it in the end because it seemed a bit overheated, but if
you approve, i shall reconsider.
so, rehearsing: all it should take is a Factory::Subclass->new(config
blah) in the startup script and a Factory::Subclass->instance() in the
handler? it does sound good if you put it like that.
incidentally I made the singleton like this (yes, more poop):
use base qw (Class::DBI::Factory Class::Singleton);
...
sub _new_instance { shift->new(@_) }
but it felt rather naughty to subclass the private _new_instance. if
anyone knows a better way, I'd be very glad to hear it.
(but this is galloping quickly away from the topic, and I'm sure I can
work it out in the end :)
thank you.
