Swagger没有显示mongoose模式中的_id

我试图在我的项目中使用swagger来获得更好的api请求帮助。一切都很好,但我在展示方面有问题 _id 属性。

我不知道该怎么连接 _身份证 在我的文档模型中,让swagger看到它。

例如,我有这样的用户文档

export class User extends Document {
  @ApiProperty({ description: 'The username of the user' })
  @Prop({ type: String, required: true })
  username: string;

  @ApiProperty({ description: 'The email of the user' })
  @Prop({ required: true })
  email: string;

  @ApiProperty({ description: 'The hashed password of the user' })
  @Prop({ required: true, min: 6 })
  password: string;

  @ApiProperty({ description: 'User roles' })
  @Prop({
    type: [{ type: String, enum: UserRole }],
    default: [UserRole.Customer],
  })
  role: string[];

  @ApiProperty({ description: 'User billing details' })
  @Prop({ type: BillingSchema, default: new Billing() })
  billing: Billing;

  @ApiProperty({ description: 'Information about user account status' })
  @Prop({ type: Boolean, default: false })
  isActive: boolean;

  @ApiProperty({ description: 'User activation token used to account activation' })
  @Prop({ type: String || null, default: null })
  activationToken: string | null;

  @ApiProperty({ description: 'User reset password token used to reset password' })
  @Prop({ type: String || null, default: null })
  resetPasswordToken: string | null;

  @ApiProperty({ description: 'List of user bought products', type: Product, isArray: true })
  @Prop([{ type: mongoose.Schema.Types.ObjectId, ref: 'Product' }])
  products: Product[];

  @ApiProperty({ description: 'Date of register' })
  @Prop({ type: Date })
  createdAt: Date;

  @ApiProperty({ description: 'Date of account last update' })
  @Prop({ type: Date })
  updatedAt: Date;
}

swagger中的任何我的用户模式都是这样的:

User{
username*   [...]
email*  [...]
password*   [...]
role*   [...]
billing*    {...}
isActive*   [...]
activationToken*    [...]
resetPasswordToken* [...]
products*   [...]
createdAt*  [...]
updatedAt*  [...]
}

我将感谢任何提示或帮助解决这个问题。
