Question

我正在使用Node，Express，Mongoose和Vue.js向Mongodb发布项目。该项目是一个混合对象和数组。对象发布将数组发布继到Mongo之后，并创建一个ID，但不会发布数据。

猫鼬模式为

   const ReportSchema = Schema(
    {
        month: String,
        projects:
        [
          {
          code: String,
          name: String,
          staff: String,
          support: String
          }               // it was missing here 
        ],

API是

app.post('/api/report/create', (req, res) => {
  const report = new Report({
    month: req.body.month,
    projects:
    [
      {
      code: req.body.projects.code,
      name: req.body.projects.name,
      staff: req.body.projects.staff,
      support: req.body.projects.support
      }
    ],

Vue.js方法是

methods: {
    create(){
      let data = { 
        month: this.month,
        projects: [
          {
            code: this.projects.code,
            name: this.projects.name,
            staff: this.projects.staff,
            support: this.projects.supported
          }
        ],

当我在Postman中执行发布请求时，对象的返回是可以的，但是数组没有发布数据。

"report": {
        "_id": "5c91b6d449f21705a0270732",
        "month": "January",
        "projects": [
            {
                "_id": "5c91b6d449f21705a0270733"
            }
        ],
        "__v": 0
    }

感谢您的帮助！

在您的创建方法中，

let data = { 
        month: this.month,
        projects: [
          {
            code: this.projects.code,
            name: this.projects.name,
            staff: this.projects.staff,
            support: this.projects.supported
          }
        ],

您将项目作为数组发送，并在API中作为对象访问它---> req.body.projects.code 在您的API中进行以下更改，它应该可以工作。

app.post('/api/report/create', (req, res) => {
  const report = new Report({
    month: req.body.month,
    projects: req.body.projects 
})

将对象和数组混合的项目发布到Mongo-数组不发布数据
