如何从 html 表单发送数组对象以遵循 mongoose 模式

问题描述 投票：0回答：1

所以我有了这个 HTML 表单，我的想法是在我的 mongo 数据库上创建一个新文档，它代表基于几个标准给老师的笔记，我在 note 属性中使用一个数组，其中包含以下对象例如，包含注释的作者。

（在浏览器中，我以以下形式输入了这些内容： 姓名 : 马西斯 || 姓氏 : de sousa || 作者：马蒂斯·德索萨）

我尝试过使用 

notes[0].author
和 
notes[0][author] without success

    <form action="/teachers" method="post">
        <input type="text" placeholder="name" name="name" required>
        <input type="text" placeholder="familyName" name="familyName" required>
        <input type="text" name="notes[0].author">
        <input type="number" name="notes[0].knowledge">
        <input type="number" name="notes[0].helpfulness">
        <input type="number" name="notes[0].attitude">
        <input type="number" name="notes[0].overallRating">
        <input type="text" name="notes[0].comment">
        <button>Submit</button>
    </form>

表单必须遵循猫鼬模式：

const teacherSchema = new mongoose.Schema({

    name: {
        type: String,
        required: true
    },
    familyName: {
        type: String,
        required: true
    },
    notes: [
    {   
        author: {
            type: String,
            required: true
        },
        knowledge: {
            type: Number,
            required: true,
            min:0,
            max:10
        },
        helpfulness: {
            type: Number,
            required: true,
            min:0,
            max:10
        },
        attitude: {
            type: Number,
            required: true,
            min:0,
            max:10
        },
        overallRating: {
            type: Number,
            required: true,
            min:0,
            max:10
        },
        comment: {
            type: String,
            required: false
        }
    }]
});

但是，要么在注释中输出空数组，要么输出这个问题

    this.$__.validationError = new ValidationError(this);

  },

}

抱歉，如果这是一个愚蠢的问题或错误的表述，我是初学者

谢谢您的帮助:)

基于以下表格：

<input type="text" placeholder="name" name="name" required>
        <input type="text" placeholder="familyName" name="familyName" required>
        <input type="text" name="notes[0].author">
        <input type="number" name="notes[0].knowledge">
        <input type="number" name="notes[0].helpfulness">
        <input type="number" name="notes[0].attitude">
        <input type="number" name="notes[0].overallRating">
        <input type="text" name="notes[0].comment">

req.body.data = {
name:"Mathis",
familyName:"de sousa"
notes:[
  {
    author:"authorName",
    knowledge:"biology",
    helpfullness:5,
    attitude:5
    overallRating:4.5
    comment:"keep it up"
    
  }
]
}
let request = req.body.data
let teacherSchema = new MODELS.teacherSchema()
teacherSchema.name = req.body.data.name
teacherSchema.familyName = req.body.data.familyName
teacherSchema.notes.push(req.body.data.notes)
await teacherSchema.save()
