日期和 Mongoose Typescript 问题

Question

我正面临 Mongoose 官方文档的问题。

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);

我的问题是IUser中created的类型与schema中的不同并且出现错误：

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

请让我知道如何解决这个问题。

Answer 1

Date.now()是一个返回number的函数。 相反，尝试仅使用new Date() 。 还需要将createdAt的类型更改为Number 。

在给定的 doc 链接中， createdAt字段类型是number但在这里你写的是Date 。

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

要么

createdAt和updatedAt是可直接使用而无需在该模式中指定时间戳。

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

我认为这是有效的

 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);
