At Dancer2, when I write below definition :
use JSON;
it does not allow with a warning that to_json and from_json functions are duplicated. I of course know that Dancer2 is using following definition
set serializer => 'JSON';
But I still could not achieve returnin JSON data: Here my route is
get '/json_branch_list' => sub {
my $sth_branch = database->prepare (qq(SELECT BranchID,Branch FROM branch WHERE Deleted=0 ));
$sth_branch->execute || die 'SQL_ERROR';
my $branch_list = [];
while (my $branch = $sth_branch->fetchrow_hashref) {
push @$branch_list, { BranchID => $branch->{BranchID}, Branch => $branch->{Branch} }; }
set serializer => 'JSON';
return $branch_list; };
No data is displayed
What happens if you do: get '/json_branch_list' => sub { [...] my $ref = { BranchID => $branch->{BranchID}, Branch => $branch->{Branch} }; return to_json($ref); } Or even, depending on what is in $branch and what you want to do with it downstream just return the hashref as-is: return to_json($branch); As far I as I know there is no need for 'use JSON', just 'use Dancer2'. Works for me anyway. -- Richard Jones
