[Entity] Table Inheritance - 클래스 상속을 이용한 테이블 늘리기

import {
  Column,
  CreateDateColumn,
  Entity,
  PrimaryGeneratedColumn,
  UpdateDateColumn,
} from 'typeorm';

export class BaseModel {
  @PrimaryGeneratedColumn()
  id: number;

  @CreateDateColumn()
  createdAt: Date;

  @UpdateDateColumn()
  updatedAt: Date;
}

@Entity()
export class BookModel extends BaseModel {
  @Column()
  name: string;
}

@Entity()
export class CarModel extends BaseModel {
  @Column()
  brand: string;
}

 

++ 상속용으로만 쓰려고 만드는거면 abstract 처리하는 것도 괜찮음.

export abstract class BaseModel {
    
}
