猫鼬型干扰

isDeleted() isDeleted 领域

我有这样的想法:

export class Factory<E> {
  private readonly _model: Model<Document & E>;

  public get model(): Model<Document & E> {
    return this._model;
  }

  constructor(config: IFactoryConfiguration) {
    // ...
    let schema: Schema = new Schema(this.definition);
    this._model = this.connection.model<Document & E>(this.name, schema);
  }
}

那么我有:

export class UserFactory extends Factory<IUser> {
  constructor(connection: Connection) {
    super({
      connection: connection,
      name: 'User',
      definition: UserSchema
    });
  }
}

以及:

export const UserSchema: SchemaDefinition = {
  // ...
  isDeleted: {
    type: Boolean,
    default: false
  } // ...
}

IUser 有 isDeleted: boolean; 财产等。

现在,我想在每次启动服务器时创建/更新系统用户:

let system = await this.factories.user.model.findOne({
  'isSystem': true
});

if (!system) {
  system = new this.factories.user.model();
  system.isSystem = true;
  system.isDeleted = true; <-- error here
  await system.save();
}

问题是我有 属性(在本例中为 尤瑟 ),但猫鼬有 isDeleted() 方法在它的 Document Intersection Type 属于 Document & IUser ,这里有干扰。我得到的错误是:

错误:(239,7)TS2322:类型“true”不能分配给类型“({(isDeleted:boolean):void;():boolean;}&false);({(isDeleted:boolean):void;():boolean;}&true)”。

因为有 isDeleted(): boolean; 方法(看一看 here ).我如何解决这个问题?
