问通过mongoose查询mongodb中的所有文档，这个代码是真的吗？

EN

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

var Panel = require("../models/Panel");

router.get("/panels", (req, res) => {
  Panel.find({}, function(err, panels) {
    if (err) res.send(err);

    console.log(panels);
    res.json(panels);
  });
});

const mongoose = require("mongoose");

const Panel = mongoose.model(
  "Panel",
  new mongoose.Schema({
    name: String,
    const: Number,
    salons: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "Salon"
      }
    ]
  })
);

module.exports = Panel;
