将 NestJs + Typegoose 中的 _id 替换为 id

Question

我使用 NestJs + Typegoose。如何在 NestJs + Typegoose 中将 _id 替换为 id？我没有找到明确的例子。我尝试过一些但没有任何结果。

@modelOptions({
  schemaOptions: {
    collection: 'users',
  },
})
export class UserEntity {
  @prop()
  id?: string;

  @prop({ required: true })
  public email: string;

  @prop({ required: true })
  public password: string;

  @prop({ enum: UserRole, default: UserRole.User, type: String })
  public role: UserRole;

  @prop({ default: null })
  public subscription: string;
}

@Injectable()
export class UsersService {
  constructor(
    @InjectModel(UserEntity) private readonly userModel: ModelType<UserEntity>,
  ) {}

  getOneByEmail(email: string) {
    return from(
      this.userModel
        .findOne({ email })
        .select('-password')
        .lean(),
    );
  }
}

更新默认值的另一种方法_id是id重写 modelOptions 装饰器中的 toJSON 方法。

@modelOptions({
    schemaOptions: {
        collection: 'Order',
        timestamps: true,
        toJSON: {
            transform: (doc: DocumentType<TicketClass>, ret) => {
                delete ret.__v;
                ret.id = ret._id;
                delete ret._id;
            }
        }
    }
})
@plugin(AutoIncrementSimple, [{ field: 'version' }])
class TicketClass {

    @prop({ required: true })
    public title!: string

    @prop({ required: true })
    public price!: number

    @prop({ default: 1 })
    public version?: number
}


export type TicketDocument = DocumentType<TicketClass>


export const Ticket = getModelForClass(TicketClass);
