Mongodb: 无法通过命令查看嵌入文档的数据

Question

对于mongodb的嵌入文档，不知道为什么数据没有保存到数据库或者别的什么可能是错的？我试图打印出所有内容以确保它能正常工作到最后一步。但是在查询嵌入文档时仍然没有得到任何结果，如下所示。

我的架构：

// create competitorAnalysisSchema
var CompetitorAnalysis = new Schema({
    firstObservation: { type: String },
    secondObservation: { type: String },
    thirdObservation: { type: String },
    brandName: { type: String },
    productCategory: { type: String },
    photo1: { data: Buffer, contentType: String },
    photo2: { data: Buffer, contentType: String },
    photo3: { data: Buffer, contentType: String },
    photo4: { data: Buffer, contentType: String }
});

// create UserSchema
var UserSchema = new Schema({
    userName: { type: String, required: true, unique: true },
    email: { type: String, required: true, unique: true },
    password: { type: String, required: true },
    currentDemo: { type: String },
    nextDemo: { type: String },
    startTime: { type: String },
    startLocation: { type: String },
    arriveTime: { type: String },
    arriveLocation: { type: String },
    leaveTime: { type: String },
    leaveLocation: { type: String },
    competitorAnalysis: [CompetitorAnalysis],
    created_at: Date,
    updated_at: Date
});

var User = mongoose.model('User', UserSchema);
module.exports = User;

在我的index.js中，所有调试信息都可以成功打印出来。:

// on routes that end in /users/competitorAnalysisTextData
// ----------------------------------------------------
router.route('/users/competitorAnalysisTextData/:userName')

    // update the user info (accessed at PUT http://localhost:8080/api/users/competitorAnalysisTextData)
    .put(function(req, res) {

        // use our user model to find the user we want
        User.findOne({ userName: req.params.userName}, function(err, user) {

            if (err)
                res.send(err);
            console.log('Got the user!');

            // update the text data
            user.competitorAnalysis.firstObservation = req.body.firstObservation;
            user.competitorAnalysis.secondObservation = req.body.secondObservation;
            user.competitorAnalysis.thirdObservation = req.body.thirdObservation;
            user.competitorAnalysis.brandName = req.body.brandName;
            user.competitorAnalysis.productCategory = req.body.productCategory;
            console.log('req.body.firstObservation: %s', req.body.firstObservation);
            console.log('user.competitorAnalysis.firstObservation: %s', user.competitorAnalysis.firstObservation);
            console.log('Save the text data for competitorAnalysisTextData!');

            // save the user
            user.save(function(err) {
                if (err)
                    res.send(err);

                res.json({ message: 'User updated!' });
                console.log('user.competitorAnalysis.firstObservation: %s', user.competitorAnalysis.firstObservation);
                console.log('Finally save the User!');
            });

        });
    })

如控制台：

Got the user in "Put"!
req.body.firstObservation: 3
user.competitorAnalysis.firstObservation: 3
Save the text data for competitorAnalysisTextData!
user.competitorAnalysis.firstObservation: 3
Finally save the User!

问题

但是，当我在 mongodb 数据库中搜索时，没有为嵌入文档保存数据：

...
"leaveTime" : "Your Current Time:\n 2016-08-23 10:27:45 AM",
"leaveLocation" : "Your Current Address:\n 1\nInfinite Loop\nCupertino\n95014",
"competitorAnalysis" : [ ]
}
> db.users.find({"competitorAnalysis.firstObservation" : "3"}).pretty()
>

此处为空！

我是 mongodb 的新手。如果我能得到一些关于我还可以检查哪里或可能是什么问题的提示，那就太好了。

更新

集合输出：

> db.users.find().pretty()
{
    "_id" : ObjectId("57ba5f41ad8858305a5d3e58"),
    "created_at" : ISODate("2016-08-22T02:11:13.968Z"),

Answer 1

这些语句是问题所在：

    user.competitorAnalysis.firstObservation = req.body.firstObservation;
    user.competitorAnalysis.secondObservation = req.body.secondObservation;
    user.competitorAnalysis.thirdObservation = req.body.thirdObservation;
    user.competitorAnalysis.brandName = req.body.brandName;
    user.competitorAnalysis.productCategory = req.body.productCategory;

您将 competitorAnalysis 数组视为一个对象。

我不使用 Mongoose，所以不知道语法，但你想做这样的事情：

user.competitorAnalysis.push({
    firstObservation: req.body.firstObservation,
    secondObservation: req.body.secondObservation,
    thirdObservation: req.body.thirdObservation,
    brandName: req.body.brandName
    productCategory: req.body.productCategory
});
