Callback model return date

[Felipo Antonoff]

No model users have the following function that returns them, but the return is always undefinid and the console.log I get the normal data, anyone know how to solve.

//Retornando usuários

 exports.usuarios = function() {

db.find({ apelido: { $exists: true } }, function (err, docs) {

return docs;

});

};

I saw in another post that has to be a callback, but I could not make it work. A function that calls:
 self.model('usuario').usuarios();

Hi Felipo,

it will not work because your model contains function with a callback:

exports.usuarios = function() {

db.find({ apelido: { $exists: true } }, function (err, docs) {

                // return WHERE?

return docs;

});

};

Solution:

exports.usuarios = function(cb) {

    db.find({ apelido: { $exists: true } }, function (err, docs) {

        cb(err, docs);
    });
};

// CONTROLLER:
self.model('usuario').usuarios(function(err, docs) {
    if (err) {
        self.view500(err);
        return;
    }
    self.json(docs);
});

Thanks :-)
