Good day Monks,

i'm trying to execute a simple insert into mongodb from dancer2, but i failwhen the insert statement call a stored function to determine the "_id" of the new document. my goal is to have as document is a simple unique auto incremental counter as documents ID.

First i save the function using mongo sheel,

> db.system.js.save({_id:"getNextSequence", value:function(name){ var 
+ret = db.counters.findAndModify({query: { _id: name },update: { $inc:
+ { seq: 1 }},new: true});return ret.seq; }});

then from Dancer2 post i try to insert the new documents:

post "/commNew" => require_login sub {
    my $userh = logged_in_user;
    my $username=$userh->{username};
    my $adm=lc(config->{app}{commAdmin});
    if($username  =~ m/$adm/){
        info ("User is $username for comm 2b" );
        my $res=$comms->insert_one({"_id"=> getNextSequence("comm-id")
+,"year" => config->{app}{year}});
        my $lastid = $res->inserted_id;
        my @kuy = body_parameters->keys;
        info ("Insert int Mongo: ".$lastid);
        foreach my $oto ( @kuy ) {
            info ("key name value: " .$oto ." value: ".body_parameters
+->get($oto));
            $comms->update_one( {"_id" => $lastid},{'$set' => {$oto =>
+ body_parameters->get($oto)}});
        }
        info ("User is $username for comm 2z" );
    }else{
        return 404;
    }
};

Instead of evaluate the stored function "getNextSequence", it try to add the document like { "_id" : "getNextSequence(\"comm-id\")",.....}

Where i'm wrong ?

thanks in advance
