Question

Given a DBIx::Class resultset, for example:

my $rs = $c->model('DB::Card')->search({family_name => 'Smith'}); 

the tutorials I’ve read use the stash to pass an arrayref of rows:

$c->stash->{cards} = [$rs->all]; 

This results in the query getting executed at this point, and the resulting objects stuffed into the stash, so they can be used in TemplateToolkit as:

[% FOREACH card IN cards %]      [% card.given_name %] [% card.family_name %]  [%END%] 

Is there a proper way to have TT iterate over the rows as they get fetched from the DB?

Answer 1

Sure. You can pass the result set directly to TT and iterate over it in the template.

$c->stash->{cards} = $rs; 

…and then:

[% WHILE (card = cards.next) %]     [% card.given_name %] [% card.family_name %] [% END %]
