javascript - Meteor returns invalid hexadecimal string error trying to create ObjectID? - Stack Overflow

I'm inserting some stuff into the database and updating it elsewhere using jQuery (give me a break, I'm new), after which I need to be able to click it and display some UI stuff, which means getting the ID. So I set the ID variable and then try and and then try and use it in the click event:

...

"click .message-entry" : function (e) {
    var id = this._id || new Meteor.Collection.ObjectID(newMessageId);
    Session.set('singleMessageId', id);
},

...

Should work in principle, however I get the following error returned:

Uncaught Error: Invalid hexadecimal string for creating an ObjectID

A breakpoint reveals that the ID is both a string and the ID of the newly inserted document. What could be going wrong here?

• (give me a break, I'm new) ?? So you are aware this may be the wrong approach, but feel it's more important to hack this together than possibly be shown a better approach? Inserting/updating items in the db and displaying them is a trivial task when you follow the established patterns. – JeremyK Commented Oct 19, 2015 at 20:44
• Anyway, what is the newMessageId variable you are passing to Meteor.Collection.ObjectID? – JeremyK Commented Oct 19, 2015 at 20:45
• Also the api is now new Mongo.ObjectID([hexString]) – JeremyK Commented Oct 19, 2015 at 20:50
• @JeremyK it's for a personal project that I need to finish asap. The variable is the ID string of the inserted document as mentioned in the question. – styke Commented Oct 19, 2015 at 21:32

By default, Meteor doesn't use Mongo's hexadecimal object IDs. You could either tell Meteor to use Mongo style IDs by passing {idGeneration: 'MONGO'} into new MongoCollection(), or (probably more easily) just use newMessageID instead of new Mongo.ObjectID(newMessageID), if the value of newMessageID is the _id returned by insert().
