尝试POST请求时猫鼬验证错误

我正在尝试制作一个包含类别和笑话的媒体应用。

当我向/ api / category / new发出POST请求时，出现此错误：

{
      message: 'Path `joke` is required.',
      name: 'ValidatorError',
      properties: [Object],
      kind: 'required',
      path: 'joke',
      value: undefined,
      reason: undefined,
      [Symbol(mongoose:validatorError)]: true
    },

我也遇到相同的错误（在此错误下方），但是对于joke路径，不是user路径。

模型

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

// Joke Schema
const jokeSchema = new Schema({
  user: { type: String , required: true},
  joke: { type: String, required: true, maxlength: 100 },
});

// Category Schema
const categorySchema = new Schema({
  name: { type: String, required: true, unique: true },
  description: { type: String, required: false },
  likes: { type: Number },
  jokes: [jokeSchema],
});

module.exports = mongoose.model("category", categorySchema);
module.exports = mongoose.model("joke", jokeSchema);

路线

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

//category model
const Category = require("../models/model");

// POST /api/category/new : Creates a new cartgory
router.post("/new", (req, res) => {
  const newCategory = new Category({
    name: req.body.name,
    description: req.body.description,
    likes: 0,
    jokes: [],
  });
  newCategory
    .save()
    .then((category) => res.json(category))
    .catch((err) => console.log(err));
});

module.exports = router;

您正在覆盖module.exports。您在models/model.js中有两个：

module.exports = mongoose.model("category", categorySchema);
module.exports = mongoose.model("joke", jokeSchema);

因此，当您const Category = require('../models/model')时，您获得的是jokeSchema而不是类别，因此与该笑话模式有关的验证错误。

只需删除module.exports = mongoose.model("joke", jokeSchema);，它应该可以工作，或按照以下步骤进行操作：

models / models.js

module.exports = {};
module.exports.category = mongoose.model('category', categorySchema);
module.exports.joke = mongoose.model('joke', jokeSchema);

routes / CategoryRouter.js

//category model
const Category = require('../models/model').category;
