无法通过邮递员和使用 mongoose 将数组值对发布到 mongoDb答案

【问题描述】：

当我尝试这样做时，我会发布其余的数据，但数组仍然为空

我的 Schma 看起来像这样

const mongoose = require('mongoose');

const DocumentSchema = mongoose.Schema({
  user: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'users',
  },
  dateCreated: String,
  title: String,
  // ID of the users that created the document
  creatorId: {
    type: mongoose.Schema.Types.ObjectId,
    ref: 'users',
  },






  comment: [{ title: String, detail: String }]



});

module.exports = mongoose.model('myDocument', DocumentSchema);

我在 postman 中的 Post 脚本是这样的

{
    "label":"Got More data",
    "linkUrl":"www.google.com",
    "title":"test 14",
    "comment":[
        {
            "title":"hello",
            "detail":"some detail"
        }]
}

当我得到我更新的数据时，它看起来像这样

  {
        "_id": "5eb91c0e35eecb369696b9c5",
        "title": "test 14",
        "creatorId": "5d8856e5903a260588b77c30",
        "user": "5d8856e5903a260588b77c30",
        "dateCreated": "Mon May 11 2020 10:34:06 GMT+0100 (British Summer Time)",
        "comment": [],
        "__v": 0
    }

我尝试过的其他事情

我已尝试根据 Stack Overflow How to define object in array in Mongoose schema correctly with 2d geo index 上的这篇文章更改架构定义

到这里

comment : [{
    title : String,
    detail : String
     }]

还有这种方法

 comment :  {
             "title":"A title",
             "detail": "some random comment"
           }

但我仍然得到一个空白数组

问题出在 react api 设置中，我没有将文件添加到下面的 api 代码中是包含“comment”字段的新代码（在 imageUrl 下）。现在可以使用了

router.post(
  '/',
  [
    auth,
    [
      check('title', ' myDocument Title is required')
        .not()
        .isEmpty()
    ]
  ],
  async (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ errors: errors.array() });
    }

    const { title, summary, imageURL, template, comment } = req.body;

    try {
      const newMyDocument = new MyDocument({
        title,
        summary,
        imageURL,
        comment,
        template,
        creatorId: req.user.id,
        user: req.user.id,
        columnOrder:["col1","col2","col3"],
        columns:[
          {col_1 :
            {
              id:"col_1",
              title:"facts",
              taskIds:["test1","test2"]
            }
          },
          {col_2 :
            {
              id:"col_2",
              title:"Pros",
              taskIds:["test1","test2"]
            }
          },
          {col_3 :
            {
              id:"col_3",
              title:"Cons",
              taskIds:["test1","test2"]
            }
          }
        ],
        dateCreated:new Date()
      });
      const myDocument = await newMyDocument.save();
      ///this is the request to othe server

      res.json(myDocument);
    } catch (err) {
      res.status(500).send('Server Error 76');
    }
  }
);
