如何在yii2中搜索过滤器multipe关系表和分组 [英] how to search filter multipe relation table and groupping in yii2

问题描述

我有三个表，比如 ridersPoint（id，nameRider，serie_id，point）和系列（serie_id，nameSerie，location，date，season_id） 和 season（season_id，nameSeason，year）。
属性 serie_id 在 riderPoint 表中与 serie_id 系列表中，以及在系列中的属性 season_id 表与 season_id 在 season 表中有关系。
如何在 riderPoint 中通过 season_id 进行搜索？当数据表在同一个季节中时如何分组点？
请帮助我。
