Mongoose throws `Field is not in schema` error when defining a field twice

问题

I am using Node v0.10.31 and mongoose@3.8.22.

I think I have encountered a bug that appears when specific things happen. The implications of this bug prevents me from having a field "name" and "father.name.full" on the same schema.

This is how I define my schema:

'use strict';

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/myapp');

var PersonSchema = new mongoose.Schema({
    name: {
        type: mongoose.Schema.Types.ObjectId,
        ref: 'Name', // if this is commented out, no errors
        required: false,
        default: null,
    },
    father: {
        name: { full: String } // if this is `name: String`, no errors
    }
}, {
    strict: 'throw' // if this is commented out, no errors
});

var Person = mongoose.model('Person', PersonSchema);

This is how I am creating the document:

var object2save = {
    name: mongoose.Types.ObjectId(),
    father: {
        name: {
            full: 'father full name'
        }
    }
}

var doc = new Person(object2save); // this throws the error

The error and stack trace is

Error: Field `name` is not in schema.

Is this actually a bug or is it a feature? If it is a feature, then it seems like a limitation on schema design. I was going to create an issue on GitHub for Mongoose, but I figured I should ask Stack Overflow first to be sure :-)
