expressjs放到了mongo db

Question

如何将数据放入mongo db中，我从前端，节点+ expressjs接收？

这是我的模特：

module.exports = mongoose.model('MyData', {
    reportData: [{
        _id: String,
        date: String,
        description: String,
        status: { type: String, default: 'new' }
    }],
    files: [{
        originalname: String,
        filename: String,
        path: String,
    }],    
    author: { type: mongoose.Schema.Types.ObjectId, ref: 'User' } })

这是put方法：

app.put('/upload/:id', bodyParser, async (req,res) => {

    var author = req.params.id;
    var report = (await MyData.find({author})).map(function(p){ return p.reportData; }).reduce(function(a, b){ return a.concat(b); }).find(x => x._id == req.body.reportId);

    report.status = req.body.event

    report.save(function(err, result){
        res.json(result);
    });

    console.log(report.status)

});

目前上面的代码返回正确状态的正确对象，但不要将其保存到数据库。
