后端未初始化数组

Question

我正在尝试在注册时发送用户对象。这个用户对象有许多属性，这些属性被发送到后端并正确地添加到数据库中。但是，有一个属性，一个名为vouchers的数组，当我添加它时，user对象不会发送到数据库。

以下是从离子前端发送到后端的用户对象的代码：

   let userobj = {
            username: this.username,
            name: this.name,
            region: this.region,
            building: this.building,
            password: this.password,
            confirmPassword: this.confirmpassword,
            points: 300,
            vouchers: [{ companyId: "", companyname: "" }]
          };

在后端，这是mongoose模型：

const mongoose = require("mongoose");
var Voucher = mongoose.Schema.Types.Voucher;

const userSchema = mongoose.Schema({
  username: {
    type: String,
    required: true,
    trim: true,
    lowercase: true
  },
  password: {
    type: String,
    required: true,
    trim: true
  },
  name: {
    type: String,
    required: true,
    trim: true
  },
  region: {
    type: String,
    required: true,
    trim: true
  },
  building: {
    type: Number,
    required: true,
    min: 0
  },
  points: {
    type: Number,
    required: false,
    min: 0
  },
  vouchers: {
    type: [Object],
    status: [String],
    required: false,
    default: []
  },

  createdAt: {
    type: Date,
    default: Date.now
  },
  updatedAt: Date
});

mongoose.model("User", userSchema);

定义vouchers有一个对象数组

vouchers: [{
    type: [Object], // There is no Schema Type in moongoose, change to [String]
    status: [String]
}]

不要担心你的vouchers: [{ companyId: "", companyname: "" }]

您想要使用companyId和companyname

更改架构..

vouchers: [{ companyId: String, companyname: String }]
