Node.js在typeorm实体中添加created_at和updated_at

I have task像这样的实体：

import {BaseEntity, Column, Entity, PrimaryGeneratedColumn} from "typeorm";

@Entity()
export class Task extends BaseEntity{
    @PrimaryGeneratedColumn()
    id:number;

    @Column()
    title:string

   @Column()
    description:string

}

我想将created_at和updated_at字段添加到该实体并自动填充它Node.js like Laravel框架。我的数据库是postgres

我们先导入一下

import { CreateDateColumn,UpdateDateColumn } from "typeorm";

在实体中添加此字段和修饰符

@CreateDateColumn({ type: "timestamp", default: () => "CURRENT_TIMESTAMP(6)" })
public created_at: Date;

@UpdateDateColumn({ type: "timestamp", default: () => "CURRENT_TIMESTAMP(6)", onUpdate: "CURRENT_TIMESTAMP(6)" })
public updated_at: Date;
