在Gridview yii2中搜索

我有一张公交路线表，它有以下规则

public function rules()
    {
        return [
            [['schedule_id', 'stop_id'], 'required'],
            [['schedule_id', 'stop_id', 'route_order', 'is_destination'], 'integer'],
            [['departure_time'], 'safe']
        ];
    }

stop\u id

（外键）是表stops的主键（id）。 现在，我想在公交线路视图中显示相应的

stop\u id

表中的

stop\u name

。为此，我在模型中添加了以下代码

public function getStop()
    {
        return $this->hasOne(Stop::className(), ['id' => 'stop_id']);
    }

在视图中

“住手，住手”

其工作正常，但搜索功能不适用于“停止名称”字段。其他字段显示要搜索的框，其中

stop\u id

字段不显示要搜索的框。如何搜索此字段

在视图文件
index.php
（可能
@app/views/bus/index.php
）


show
searchModel
，Ajith.使用
$query->andFilterWhere（['like'，'stop.stop\u name'，$this->stop\u id]）
它不起作用，没有搜索字段出现
$dataProvider->sort->attributes[stop\u id']=['asc'=>['stop.stop\u name'=>sort\u asc]，'desc desc参考：和
