yii2-如何使用搜索模型搜索值

Question

我正在研究 yii2。我有一个型号名称 RouteMeters。在这里，我有一个 meter_id ，其中保存了仪表的所有 ID。在我的索引视图中，我显示了 meter_id 的值，如下所示

[
            'attribute' => 'mter_id',
            'label' => 'Meters',
            'value' => function ($data) {
                if (is_object($data->mter))
                    return $data->mter->meter_msn;
                return ' - ';
            },

        ],

视图在下方

但是当我用电表号搜索电表时，没有找到记录。

下面是我对 RouteMeters

的搜索模型

 public function search($params)
{
    $query = RouteMeters::find();

    // add conditions that should always apply here

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    $this->load($params);

    if (!$this->validate()) {
        // uncomment the following line if you do not want to return any records when validation fails
        // $query->where('0=1');
        return $dataProvider;
    }

    // grid filtering conditions
    $query->andFilterWhere([
        'id' => $this->id,
        'route_id' => $this->route_id,
        'mter_id' => $this->mter_id,
        'user_id' => $this->user_id,
    ]);
    if (!Yii::$app->user->isGuest && in_array(Yii::$app->user->identity->user_role, [3,4])) {
        $query->joinWith('teamsuser', true);
        $query->andFilterWhere(['=', 'user.group_id', Yii::$app->user->identity->group_id]);
    }

    $query->orderBy(['id' => SORT_DESC]);
    return $dataProvider;
}

现在在我的搜索模型中，我想放置一个查询，该查询将在我的索引视图中搜索时为我提供所选仪表编号的记录。

电表的序列号在我的 meters table 中，文件名 meter_msn，我想加入它。

我不知道如何处理我的搜索模型。

非常感谢任何帮助。

public function search($params)
{
    $query = RouteMeters::find()->joinWith('mter');

    // add conditions that should always apply here

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    $this->load($params);

    if (!$this->validate()) {
        // uncomment the following line if you do not want to return any records when validation fails
        // $query->where('0=1');
        return $dataProvider;
    }

    // grid filtering conditions
    $query->andFilterWhere([
        'id' => $this->id,
        'route_id' => $this->route_id,
        //'mter_id' => $this->mter_id,
        'user_id' => $this->user_id,
    ]);
    if (!Yii::$app->user->isGuest && in_array(Yii::$app->user->identity->user_role, [3,4])) {
        $query->joinWith('teamsuser', true);
        $query->andFilterWhere(['=', 'user.group_id', Yii::$app->user->identity->group_id]);
    }

    $query->andFilterWhere(['like', 'meterTableName.meter_msn',  $this->mter_id]);
    $query->orderBy(['id' => SORT_DESC]);
    return $dataProvider;
}
