如何修复“ValidationError：用户验证失败：名称：需要路径‘name’。” Mongo 错误？

我正在创建一个新用户并检查用户电子邮件以前是否存在。如果不是，那么它正在创建一个新用户并保存它。我需要什么来纠正我得到的这个验证错误？

我已经尝试过将名称设置为不需要。但它仍然不起作用。

这是我的用户模型。

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

//Declaring User Model
const UserSchema = new Schema({
  name: {
    type: String,
    required: true
  },
  password: {
    type: String,
    required: true
  },
  email: {
    type: String,
    required: true
  },
  avatar: {
    type: String
  },
  date: {
    type: Date,
    default: Date.now
  }
});

module.exports = User = mongoose.model("users", UserSchema);

这是用户路线。

router.post("/register", (req, res) => {
  User.findOne({ email: req.body.email }).then(user => {
    if (user) {
      return res.status(400).json({ email: "email already exists" });
    } else {
      const avatar = gravatar.url(req.body.email, {
        s: "200", //size
        r: "pg", //rating
        d: "mm" //default
      });
      const newUser = new User();
      const newUser = {
        name: req.body.name,
        email: req.body.email,
        avatar,
        password: req.body.password
      };
      bcrypt.genSalt(10, (err, salt) => {
        bcrypt.hash(newUser.password, salt, (err, hash) => {
          if (err) throw err;
          newUser.password = hash;
          newUser
            .save()
            .then(user => res.json(user))
            .catch(err => console.log(err));
        });
      });
    }
  });
});

我期待它被存储。这是我得到的错误。

在您的代码中，我可以看到您将

newUser

基本上你需要用这些值制作模型对象。

const newUser = new User({
   name: req.body.name,
   email: req.body.email,
   avatar,
   password: req.body.password
});
