【中文标题】Mongoose ValidationError：验证失败：需要路径

【英文标题】：Mongoose ValidationError: validation failed: Path is required

【问题描述】：

当我在我的 Web 应用程序的 ejs 表单中输入与我的 mongoDB 架构有关的信息时出现错误：

我得到的错误：

ValidationError: Subscriber validation failed: grade1: Path `grade1` is required., grade2: Path `grade2` is required., grade3: Path `grade3` is required., grade4: Path `grade4` is required.

我的订阅者架构：

const mongoose = require("mongoose");
const subscriberSchema = new mongoose.Schema(
  name: 
    type: String,
    required: true
  ,
  grade1: 
    type: String,
    required: true
  ,
  grade2: 
    type: String,
    required: true
  ,
  grade3: 
    type: String,
    required: true
  ,
  grade4: 
    type: String,
    required: true
  
);

subscriberSchema.methods.getInfo = function() 
  return `Name: $this.name grade1: $this.grade1 grade2: $this.grade2 grade3: $this.grade3 grade4: $this.grade4`;
;

subscriberSchema.methods.findLocalSubscribers = function() 
  return this.model("Subscriber")
    .find(
      name: this.name
    )
    .exec();
;

ejs 形式：

<div class="col-sm-6">
  <h1>Enter Student Name and Grades</h1>
  <p>Enter the student's name and grades for the first 4 CSC courses:</p>
  <form class="subscription-form" action="/subscribers/create" method="post">
    <input type="text" name="name" placeholder="Name" autofocus>
    <input type="text" grade1="grade1" placeholder="CSC141 Grade" required>
    <input type="text" grade2="grade2" placeholder="CSC142 Grade" required>
    <input type="text" grade3="grade3" placeholder="CSC240 Grade" required>
    <input type="text" grade4="grade4" placeholder="CSC241 Grade" required>
    <input type="submit" name="submit">
  </form>
</div>

订阅者/在订阅者控制器中创建：

  create: (req, res, next) => 
    let subscriberParams = 
      name: req.body.name,
      grade1: req.body.grade1,
      grade2: req.body.grade2,
      grade3: req.body.grade3,
      grade4: req.body.grade4
    ;
    Subscriber.create(subscriberParams)
      .then(subscriber => 
        res.locals.redirect = "/subscribers";
        res.locals.subscriber = subscriber;
        next();
      )
      .catch(error => 
        console.log(`Error saving subscriber: $error.message`);
        next(error);
      );
  ,
...

我是 mongoDB/nodejs/ejs 的新手，所以我想知道我做错了什么。

【参考方案1】：

它适用于name，因为您使用的是 html 表单 name 属性，请尝试：

<input type="text" name="grade1" placeholder="CSC141 Grade" required>
<input type="text" name="grade2" placeholder="CSC142 Grade" required>
<input type="text" name="grade3" placeholder="CSC240 Grade" required>
<input type="text" name="grade4" placeholder="CSC241 Grade" required>
