如何在NGRX中更新实体的选择ID

// 实体状态存储模型
interface EntityState<T> {
  ids: string[];
  entities: { [id: string]: T };
  selectedId: string | null;
}

// Action类型定义
enum EntityActionTypes {
  UpdateSelectedId = '[Entity] Update Selected ID',
}

class UpdateSelectedId implements Action {
  readonly type = EntityActionTypes.UpdateSelectedId;
  constructor(public payload: string) {}
}

type EntityActions = UpdateSelectedId;

// Reducer函数
function entityReducer(state: EntityState<Entity>, action: EntityActions): EntityState<Entity> {
  switch (action.type) {
    case EntityActionTypes.UpdateSelectedId:
      return { ...state, selectedId: action.payload };
    default:
      return state;
  }
}

// 组件中的代码
import { Store } from '@ngrx/store';
import { UpdateSelectedId } from './entity.actions';

@Component({
  // 组件配置
})
export class MyComponent {
  constructor(private store: Store) {}

  updateSelectedId(id: string) {
    this.store.dispatch(new UpdateSelectedId(id));
  }
}
