Meteor collection update with traditional id

Question

Im trying to do a simple update

Collection.update(id, {$set:{name:value}}); 

or even

Collection.update({'_id':id}, {$set:{name:value}}); 

But the collection won't update if the id is a traditional mongodb id. It only seems to work with meteors own implentation of unique id's. How can I remedy this. Is it possible for meteor to accept mongo's own id structure?

Answer 1

You're right: Meteor's DDP protocol doesn't support non-JSON types such as Mongo ObjectId. We know this is a problem: it's our oldest open issue and it's on our roadmap.

While there are definitely some "easy" quick fixes that would resolve this issue, we'd prefer to do this in the context of extending our protocol to handle other non-JSON types (dates, binary blobs, etc) rather than a specific short-term hack.

It's possible to convert your ID into a mongodb object (on the server side) by using new ObjectID and then do the update. :

var ObjectID, require;

require = __meteor_bootstrap__.require;

ObjectID = require("mongodb").ObjectID;

Meteor.methods({
  SomeUpdate: function(upd) {
    var id;
    id = new ObjectID(upd['_id']);
    return SomeDB.update({
      _id: id
    }, {
      $set: {
        field: value
      }
    }, function(res) {
      return console.log(res);
    });
  }
});
