Question

我正在使用猫鼬，我想搜索多个集合并使用_id属性删除。

我正在从用户那里收到一个_id数组，并且我正在尝试遍历每个元素。

var express = require("express");
const mongoose = require("mongoose");
const router = express.Router();


router.delete("/", async (req, res) => {
  let data = req.body; // this is an array of _id from the user


   data.forEach((element) => {
    let models = [];
    models.push(mongoose.models.Furniture);
    models.push(mongoose.models.Clothing);
    models.map((model) => model.findByIdAndRemove(element));
  });
});

module.exports = router;

运行此程序时，我没有收到任何错误。

MongoDB操作是异步操作。因此，要获取错误或结果，您需要等待数据库返回响应。

var express = require("express");
const mongoose = require("mongoose");
const router = express.Router();


router.delete("/", async (req, res) => {
  let data = req.body; // this is an array of _id from the user


   data.forEach((element) => {
    let models = [];
    models.push(mongoose.models.Furniture);
    models.push(mongoose.models.Clothing);
    try {
      models.map(async (model) => { await model.findByIdAndRemove(element)});
    } catch (error) { console.log(error) }
  });
});

module.exports = router;
Note: this code is not tested locally but the problem I have solved here
