如何在nestjs mongodb中加载嵌入的参考模式？

目前我正在使用 Nestjs 开发 API。它有如下代码。

@ObjectType()
@Schema()
@InputType('BuyInput', { isAbstract: true })
export class Buy extends CoreEntity {
  @Prop(raw([BuyItemType]))
  @Field(() => [BuyItemType])
  items: BuyItemType[];

  @Prop({ type: mongoose.Schema.Types.ObjectId, ref: 'User' })
  user: User;

  @Prop({
    type: String,
    enum: BuyStatus,
  })
  @Field(() => BuyStatus)
  @IsEnum(BuyStatus)
  status: BuyStatus;

  @Field()
  @Prop({ name: 'deliveryCharge' })
  deliveryCharge: number;

  @Field()
  @Prop({ name: 'finalCharge' })
  finalCharge: number;
}

其中以用户作为参考架构。现在我必须在查询购买模式时使用填充来获取用户。像这样。

buyModel.find().populate('user');

我可以在不使用 populate 的情况下自动加载吗？

Currently I am working on API using nestjs. It has the code like below.

@ObjectType()
@Schema()
@InputType('BuyInput', { isAbstract: true })
export class Buy extends CoreEntity {
  @Prop(raw([BuyItemType]))
  @Field(() => [BuyItemType])
  items: BuyItemType[];

  @Prop({ type: mongoose.Schema.Types.ObjectId, ref: 'User' })
  user: User;

  @Prop({
    type: String,
    enum: BuyStatus,
  })
  @Field(() => BuyStatus)
  @IsEnum(BuyStatus)
  status: BuyStatus;

  @Field()
  @Prop({ name: 'deliveryCharge' })
  deliveryCharge: number;

  @Field()
  @Prop({ name: 'finalCharge' })
  finalCharge: number;
}

which has user as reference schema. Right now I have to use populate to get user while querying Buy schema. like this.
