I am trying to obtain JSON from a DBIx::Class::ResultSet and I get the exception
encountered object 'Sql2Json::Model::DB::Book=HASH(0x6014f88)',
but neither allow_blessed, convert_blessed nor allow_tags settings are
enabled (or TO_JSON/FREEZE method missing)
The controller class is Books.pm :
package Sql2Json::Controller::Books;
use Moose;
use namespace::autoclean;
use JSON::XS;
BEGIN { extends 'Catalyst::Controller'; }
my $json = JSON::XS->new;
sub list : Local {
my($self, $c) = @_;
$c->stash(books_rs => $c->model('DB::Book'));
$c->stash(books => [$c->stash->{books_rs}->search({}, {order_by => 'name ASC'})]);
$c->stash(json_data => $json->convert_blessed->encode($c->stash->{books}));
$c->forward('View::JSON');
}
__PACKAGE__->meta->make_immutable;
1;
According to this article is enough the encoding of blessed objects:
$json->convert_blessed->encode($c->stash->{books})
Do I missing somethig here?
Almost all the time, the best way to do this is using the get_inflated_column method of the rows returned from a query.
$books = $c->model('DB::Book');
$c->stash(json_data => [map {$_->get_inflated_columns} $books->all]);
$c->forward('View::JSON');
