Mongoose embedded document updating

Question

I have a problem with embedded document update.

My defined Schemas:

var Talk = new Schema({
    title: {
        type: String,
        required: true
            


        

Answer 1

It's because you are trying to save your talk object before the callback which increments count has been fired. Also, did you make sure to instantiate your Talk schema? eg:

var talk = new Talk();

However, if all you want to do is increment your count variable, mongo supports atomic, in-place updates which you may find useful:

talk.find( { _id : req.body.vote }, { $inc: { count : 1 } } );
