InsertMany 在 mongodb 中不起作用

我对 Mongoose 和 MongoDB 本身相当陌生，我试图保存一堆通过 insertMany 方法插入的文档，但它没有保存文档。

这是我的代码：

Model:

var mongoose = require('mongoose');
var Schema = mongoose.Schema;


var hostSchema = new Schema({
    hostname: String,
    timestamp: Number,

});

var hostModel = mongoose.model('host', hostSchema, 'host');

module.exports = hostModel;

ExpressJS 邮政路线

var mongoose = require('mongoose');
var hostModel = require('../../models/Host');

router.post('/host', function (req, res, next) {
    var payload = req.body;

    (async function(){
        var host = new hostModel();

        const insertMany = await hostModel.insertMany(payload.data);

        console.log(JSON.stringify(insertMany,'','\t'));

        const saveMany = await hostModel.save();

        res.status(200).send('Ok');
    })();
});

That console.log向我展示记录，但是当我这样做时hostModel.save() I get hostModel.save is not a function.

如何保存插入的文档？

非常感谢您的帮助！

无需创建实例new hostModel()这里...直接使用hostModel并且也没有必要save()也因为插入许多本身创建了集合......并确保payload.data有对象数组

router.post('/host', function (req, res, next) {
  const array = [{hostname: 'hostname', timestamp: 'timestamp'},
                 {hostname: 'hostname', timestamp: 'timestamp'}]

    var payload = req.body;

    (async function(){

        const insertMany = await hostModel.insertMany(array);

        console.log(JSON.stringify(insertMany,'','\t'));

        res.status(200).send('Ok');
    })();
});
