我正在尝试更新Mongo集合中的多个子文档,其中同一集合中可能存在多个匹配项.不幸的是,它只更新每个文档中具有匹配项的第一个子文档.

这是代码:

var mongoose = require('mongoose');

mongoose.connect('mongodb://127.0.0.1/touchbits');

var PartsSchema = new mongoose.Schema({
        type: String
        , partNbr: Number
    });

var ProductSchema = new mongoose.Schema({
        sku: { type: String, unique: true }
        , parts: [PartsSchema]
    });

Product = mongoose.model('Product', ProductSchema);

var cigars = new Product({
        sku: 'cigar123',
        parts: [{type: 'tobacco', partNbr: 4}, 
                {type: 'rolling paper', partNbr: 8}, 
                {type: 'tobacco', partNbr: 4}]
    });
var cigarillo = new Product({
        sku: 'cigarillo456',
        parts: [{type: 'tobacco', partNbr: 4}, 
                {type: 'crush paper', partNbr: 12}]
    });

cigars.save(function(err, product1) …
