Guess I didn't step away enough to have it make sense to anyone else....
That said, here's some code:
sub cgiapp_prerun {
my $self = shift;
my $dbh = $self->{DBH} = $self->param('DBH');
### let's check for storage;
my $previousClass = $self->query->param('this');
my $className = "DataClasses::${previousClass}";
if ( $className->SUPER::can( 'new' )
and $className->SUPER::can( 'store') ) {
my $object = $className->new(
DBH => $dbh, REQUEST => $request );
## the needStorage method allows us to
## have multiple "screens" using the same class
## where not all of them store in the DB
$object->store() if $object->needStorage();
}
}
}
and the store() method ...
sub store {
my ( $self, %params )_ = @_;
### if insert ...
$self->query->param( -name => 'whatever', -value => '123');
$self->param( 'whatever', '123' );
return 1;
}
both methods of stashing the value until the runmode is executed failed. as i've understood the calling stack:
CGI::App->new() -> prerun -> setup -> "runmode" -> teardown
so i don't see how something set in one mode wouldn't carry into another, because it's the same "run cycle".
