日期和 Mongoose Typescript 問題

Question

我正面臨 Mongoose 官方文檔的問題。

import { Schema, Model, model } from 'mongoose';

export interface IUser {
  name: string;
  email: string;
  avatar?: string;
  created: Date;
}

const schema = new Schema<IUser, Model<IUser>, IUser>({
  name: { type: String, required: true },
  email: String,
  avatar: String,
  created: { type: Date, default: Date.now },
});

export const UserModel = model<IUser>('User', schema);

我的問題是IUser中created的類型與schema中的不同並且出現錯誤：

Type '{ type: DateConstructor; default: () => number; }' is not assignable to type 'typeof SchemaType | Schema<any, any, undefined, unknown> | Schema<any, any, undefined, unknown>[] | readonly Schema<any, any, undefined, unknown>[] | Function[] | ... 6 more ... | undefined'.
  Types of property 'type' are incompatible.
    Type 'DateConstructor' is not assignable to type 'Date | typeof SchemaType | Schema<any, any, undefined, unknown> | undefined'.
      Type 'DateConstructor' is missing the following properties from type 'typeof SchemaType': cast, checkRequired, set, getts(2322)
(property) created?: typeof SchemaType | Schema<any, any, undefined, unknown> | Schema<any, any, undefined, unknown>[] | readonly Schema<any, any, undefined, unknown>[] | Function[] | ... 6 more ... | undefined

請讓我知道如何解決這個問題。

Answer 1

Date.now()是一個返回number的函數。 相反，嘗試僅使用new Date() 。 還需要將createdAt的類型更改為Number 。

在給定的 doc 鏈接中， createdAt字段類型是number但在這里你寫的是Date 。

interface User {
  name: string;
  email: string;
  avatar?: string;
  createdAt: number;
}

要么

createdAt和updatedAt是可直接使用而無需在該模式中指定時間戳。

const schema = new Schema<IUser, Model<IUser>, IUser>({
  name: { type: String, required: true },
  email: String,
  avatar: String
},{
    timestamps: true
});

Answer 2

我認為這是有效的

 import { Schema,Document } from 'mongoose';
 export interface IUser {
     name: string;
     email: string;
    avatar?: string;
   created: Date;
}
const schema = new Schema<IUser>({
    name: { type: String, required: true },
    email: String,
    avatar: String,
    created: { type: Date, default: Date.now },

});

export const UserModel = model<IUser>('User', schema);
