get a random document from a collection (meteor, mongodb)

gistfile1

randomInRange = function(min, max) {
    var random = Math.floor(Math.random() * (max - min + 1)) + min;
    return random;
}


randomFromCollection = function(C) {
    return function() {
        c = C.find().fetch();
        i = randomInRange(0, c.count())
        return c[i]
    }
}

You might want to use Random.choice(arrayOrString) which is already included as part meteor. From the Meteor docs http://docs.meteor.com/#random

Using findone appears a lot more efficient, you could just feed the random number (which you calculate with randomInRange(0,collection.count()) into the skip argument
