I try the code like this:
my @rows = getRows($sth);
$self->stash(rows => \@rows);
The getRows is a sub function name, and the code works in template. The $rows is a Array.
I write code like this:
$self->stash(rows => \getRows($sth));
The $rows is a REF, It's wrong.
If write code like this:
$self->stash(rows => getRows($sth));
The $rows is a HASH, It's wrong.
Is there any way to write the two line code in one?
Yes. You can write
$self->stash(rows => [getRows($sth)]);
The square brackets []
serve to create the desired reference.
