Query Return Collection From MongoDb Mongoose in Node

Question

Is it possible to query a returned collection in mongoose for mongodb. So in the example below I wish to return to the page the full list of steps, as well as the currentStep. The line I am unsure about is currentStep: steps.?????(page).

Thanks

var page = (req.params.page == undefined?1:req.params.page)
db.stepModel.find().sort({number:1}).exec(function(err, steps) {
 if (err) { return next(err); }
 res.render('scheme', { 
   title: 'Fnol',
   user: req.user, 
   steps:steps,
   currentStep: steps.?????(page), 
   page:page
 });
};

You can use steps as an array:

currentStep : steps[page - 1].toObject()

The - 1 is because it seems that you use 1-based indexing for the page, whereas arrays are 0-based.

The toObject() converts the Mongoose result into a proper JS object, so you can access properties like _id from within your template.
