Hi, is there a way to generate MongoDB ObjectIDs in cloud code? For use in subdocuments/subobjects stored inside an array inside a top-level MongoDB document.

Something like this, from the NodeJS MongoDB driver:

var ObjectID = require('mongodb').ObjectID;

var generatedId = new ObjectID();

Can't find any cloud code method to do that, but I might have missed it.

Thanks

I'll let GS support answer for certainty, but I'm pretty sure no.

We just use a Redis key as an auto incrementing counter as suggested in their docs:

var uniqueId = Spark.getRedis().incr("uniqueId");

We use this to generate object ids:

function objectId (now)
{
    var timestamp = ((now || (new Date()).getTime()) / 1000 | 0).toString(16);

    return timestamp + 'xxxxxxxxxxxxxxxx'.replace(/[x]/g, function() {
        return (Math.random() * 16 | 0).toString(16);
    }).toLowerCase();
};

Thanks, that seems like a good workaround.
