Answer 1

You may use { "$setOnInsert": { value: 31 } } Doc

Ref: https://groups.google.com/forum/#!topic/mongoose-orm/WuJSqxPX8T8

syntax: findOneAndUpdate([query], [doc], [options], [callback]) Doc

example:

model.findOneAndUpdate(
      { username: 'john' },
      { "$setOnInsert": { points: '0' },
            $push: {
            "boards": {
                "account":req.body.account,
                "game":req.body.game                                        
            }
        }          
      { upsert: true},
      function(err, doc) {    

      });

Answer 2

What's going on is that none of Mongoose's validation, middleware, or default values are used when calling any of the "update" family of methods, like findByIdAndUpdate. They're only invoked by calls to save or create.

The reason for this is that the "update" calls are effectively pass-throughs to the native driver, with Mongoose only providing type-casting of the fields based on the schema definition.

Mongoose 4.0 Update

Mongoose now supports setting defaults when a new document is created during an update, findOneAndUpdate, or findByIdAndUpdate upsert. Set the setDefaultsOnInsert option to true to enable this. This uses the $setOnInsert operator to create the defaults on insert.

var queryOptions = {
    upsert: true,
    setDefaultsOnInsert: true
};
Company.findByIdAndUpdate(id, company, queryOptions).exec( ...
