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.
