为什么我没有得到与typeorm和nest.js的重载匹配

Question

嘿，我正试图为任务创建一个实体，并使用这个实体

这是我的任务实体：

import {
Column,
CreateDateColumn,
Entity,
JoinColumn,
OneToOne,
PrimaryGeneratedColumn,
UpdateDateColumn,
} from 'typeorm';
import { Status } from './Status.entity';
import { User } from './User.entity';
@Entity()
export class Task {
@PrimaryGeneratedColumn({
type: 'bigint',
name: 'task_id',
})
id: number;
@Column()
title: string;
@Column()
description: string;
@OneToOne(() => Status)
@JoinColumn()
status: Status;
@OneToOne(() => User)
@JoinColumn()
createdBy: User;
@OneToOne(() => User)
@JoinColumn()
updatedBy: User;
@CreateDateColumn({
type: 'timestamp',
name: 'created_at',
})
createdAt: Date;
@UpdateDateColumn({
type: 'timestamp',
name: 'updated_at',
})
updateAt: Date;
}

我已经拥有了项目中的其他一切，比如状态实体和用户实体

当我试图创建一个像这样的任务时

async insertTask(title: string, description: string, userId: number) {
const userDetails = await this.findUser(userId)
const newTask = this.TaskRepository.create({
title,
description,
createdBy: userDetails,
});
const res = await this.TaskRepository.save(newTask)
return res;
}

我得到这个错误：

我已经被这件事困扰了很长一段时间了，任何帮助都将不胜感激，感谢

这是因为Task上的updatedBy和createdBy字段的类型为User，但您提供的是number(userId参数(。
