i believe you are getting an array-ref because you are calling it in
list context via the [ ... ] here.
my $myalums = [ $c->model('MyDB::Alumni')->search({}, { rows =>
20 }) ] ;
try:
my $myalums_iter = $c->model('MyDB::Alumni')->search({}, { rows
=> 20 });
while (my $alum = $myalums_iter->next) { ... }

Because ->next isn't a method on an array reference.
You could try derefing via @$myalumns.
I have tried a few things here. I can get this to work:
for my $element (@{$myalums}) {
$c->log->debug("alum:". $element->alumni_id);
}
but not :
while (my $alum = @{$myalums}->next) {
$c->log->debug("id: ". $alum->alumni_id);
}
In this case I get:
Can't call method "next" without a package or object reference
I'm assuming I'm just doing something obviously wrong here?
Thanks!
John
