使用猫鼬和Express / Node Js提取数据

我试图使用mongoose从MongoDB数据库中获取数据并在Node js中表达,我创建了Model并成功连接到数据库,但是问题是当数据库集合中已经有文档时,我得到的响应是空的。

模型类:

const mongoose = require("mongoose");
const RendezvousSchema = mongoose.Schema({
    idpatient: {
        type: String,
        required: true
    },
    idmedecin: {
        type: String,
        required: true
    },
});

module.exports = mongoose.model("Rendezvous", RendezvousSchema);

index.js:

const express = require("express");
const router = express.Router();
const Rendezvous = require("../model/RendezVous");
/* Get Rendez Vous By id */
/**
 * @method - GET
 * @description - Get Rendez vous Medecin
 * @param - /user/GetRdvMedecin
 */
router.get("/GetRdvMedecin", async (req, res) => {
  try {
    const rdv = await Rendezvous.find();
    res.json(rdv);
    console.log('Fetched');
  } catch (e) {
    res.send({ message: "Error in Fetching rendez vous" });
  }
});
/* Get Rendez Vous By id*/
module.exports = router;

这是console.log:


Server Started at PORT 4000
Connected to DB !!
Fetched

邮递员GET请求:“ http://localhost:4000/user/GetRdvMedecin

邮递员回复:'[]'

文档样本:

{
  "_id":{
    "$oid":"5e7396787b32a12e38a7aa7d"
  },
  "idpatient":"5e6ce11bc31de6132ca454a1",
  "idmedecin":"5e5aa519190d8c2818a66a0a"
}

提示:当我使用另一个模型(“用户”)时,它工作正常并返回响应。

您的请求.find()可以返回多个对象,我总是返回如下内容:

input.next()

通过在模型中添加集合名称来解决

const mongoose = require("mongoose");

const RendezvousSchema = mongoose.Schema({
    idpatient: {
        type: String
    },
    idmedecin: {
        type: String
    }
},{
    collection: 'Rendezvous'
});

// export model user with UserSchema
module.exports = mongoose.model("Rendezvous", RendezvousSchema);
