出现错误：Type 'Usersinterface' 不满足约束文档

Question

以下是错误截图：

这是用户界面的代码：

export class Usersinterface {
    readonly username: string;
    readonly password: string;
}

这是用户服务的代码：

import { Injectable, Inject, BadRequestException } from '@nestjs/common';
import {Usersdto} from './users.dto'
import {Usersinterface} from './users.interface'
import { Model } from 'mongoose';
import * as bcrypt from 'bcrypt';
import { InjectModel } from '@nestjs/mongoose';

@Injectable()
export class UsersService {
    private hashLength = 16;
    constructor(@Inject('Usersinterface') private readonly userModel: Model<Usersinterface>) {}

}

Answer 1

试试这样的：

import * as mongoose from 'mongoose';

export class Usersinterface extends mongoose.Document {
    readonly username: string;
    readonly password: string;
}
