mongodb - How to return Mongoose results from the find method?

Question

Everything I can find for rending a page with mongoose results says to do it like this:

users.find({}, function(err, docs){
    res.render('profile/profile', {
        users:     docs
    });
});

How could I return the results from the query, more like this?

var a_users = users.find({}); //non-working example

So that I could get multiple results to publish on the page?

like:

/* non working example */
var a_users    = users.find({});
var a_articles = articles.find({});

res.render('profile/profile', {
      users:    a_users
    , articles: a_articles
});

Can this be done?

You're trying to force a synchronous paradigm. Just does't work. node.js is single threaded, for the most part -- when io is done, the execution context is yielded. Signaling is managed with a callback. What this means is that you either have nested callbacks, named functions, or a flow control library to make things nicer looking.

async.parallel([
   function(cb){
      users.find({}, cb);
   },
   function(cb){
      articles.find({}, cb);
   }
], function(results){
   // results contains both users and articles
});
