mongoose .save()不起作用

Question

我有这些代码运行尝试将对象保存到MongoDB中.

该.save()从来没有成功运行.代码运行正常.

.save()方法不起作用.

var conn = mongoose.createConnection(mongoUrl, {auth: {authdb: "admin"}});
conn.on('error', function (err) {
    throw err;
});
conn.once('open', function callback() {
    console.log("connected to " + mongoUrl);
    var cacheSchema = mongoose.Schema({}, {strict: false});
    cacheSchema.set('collection', 'caches');
    // you need to specify which connection is uing.
    var Cache = conn.model('cache', cacheSchema);
    var measure = new Cache();
    measure['test'] = "test";
    measure.save(function(err){
        console.log('test');
    });
});

我刚刚在我的代码中遇到了类似的问题.对我来说,我正在处理用户文档中的对象.我不得不运行user.markModified('object')前user.save(),确保更改已保存到数据库中.我的运行理论是Mongoose没有自动跟踪未设置或从数据库中删除的项目
