iolo / mongo-q Goto Github PK

I'm trying out mongo-q in my REST API. Here's the original non-promise code I'm converting from which works fine:

mongo.Db.connect(mongoUri, function (err, db) {
db.collection('checkboxes', function(err, collection) {
collection.find().toArray(function(err, items) {
res.send(items);
});
});
});

The code with promises looks like this:

mongo.Db.connectQ(mongoUri)
.then(function(db){
return db.collectionQ('checkboxes');
})
.then(function(collection){
return collection.find().toArrayQ();
})
.then(function(items){
res.send(items);
})
.fail(function(err){
console.log('Error: ', err);
})
.done();

Am I doing something wrong?
