Question

我想按以下格式将数据对象数组存储到mongodb中。

'

certifications' = {
                                  'certification1' = { 'name': ' SQL Server'},
  'certification2' = { 'name': 'Angular'},
....
}

同样，我想将数据存储到monogodb字段数组中。

证书3，证书4是动态的，它来自客户端。

如何实现该功能，请帮助我...

制作像这样的猫鼬模型：

const certificationSchema = new Schema({
    name: {
        type: String,
        required: true,
        minlength: 3,
        maxlength: 255,
    }
});

module.exports = mongoose.model('certification', certificationSchema);

在API路由中：

// certification.js

const Certification = require('../models/Certification');

// req.body = [{"name": "google"}, {"name": "SQL Server"}]

router.post('/', (req, res, next) => {
        // Model.insertMany() inserts an array of documents into a MongoDB collection should all of them be validated
        Certification.insertMany(req.body)
        .then((certification) => {
            if (certification) {
                   res.json(certification);
            } else {
                return next(new Error('Insertion failed'));
            }
        }).catch((err) => {
            next(err['message']);
        })
});

如何使用Mongoose将动态对象数组存储在mongodb中？
