Model 在Yii2中显示与给定给用户的节点相关的记录

我正在做

yii2

。我有一个视图，其中我正在向用户显示一些数据。存在具有节点的用户层次结构

用户已附加到节点

节点已附加到客户

将节点分配给客户时，将在所选节点下创建客户。子节点not（即customer）也具有父节点id，该id告诉此客户已附加到该节点

客户被连接到一个仪表上

下面是我正在显示的数据

我想做什么？

在我上面的视图中，我只想显示与给定给用户的节点一起附加的

客户ID

和

仪表

数据

在我的

搜索模型中

public function search($params)
{
    if(Yii::$app->user->identity->user_role ==1)
    {
      // do nothing as the user is admin
    }
    else
    {
        $user_id = \Yii::$app->user->id;           

    }


    $query = MdcmetersData::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' => $this->id,
        'cust_id'=>$this->cust_id,
        'data_date_time' => $this->data_date_time,
    ]);

    $query->andFilterWhere(['like', 'msn', $this->msn])
        ->andFilterWhere(['like', 'device_id', $this->device_id])
        ->andFilterWhere(['like','cust_id', $this->cust_id])
        ->andFilterWhere(['like', 'kwh_t', $this->kwh_t])
        ->andFilterWhere(['like','d_type', $this->d_type])
        ->andFilterWhere(['like', 'voltage_p1', $this->voltage_p1])
        ->andFilterWhere(['like', 'voltage_p2', $this->voltage_p2])
        ->andFilterWhere(['like', 'voltage_p3', $this->voltage_p3])
        ->andFilterWhere(['like', 'current_p1', $this->current_p1])
        ->andFilterWhere(['like', 'current_p2', $this->current_p2])
        ->andFilterWhere(['like', 'current_p3', $this->current_p3])
        ->andFilterWhere(['like', 'data_date_time', $this->data_date_time]);

    $query->andWhere(['not',['cust_id'=>null]]);
    $query->andWhere(['not',['cust_id'=>'']]);
    $query->orderBy(['data_date_time' => SORT_DESC]);
    return $dataProvider;
}

节点表（mdc\U节点）

I上表

GIS办公室

是

客户

，附在

一楼

下。将客户与节点连接时，将在所选节点（即子节点）下创建一个新节点

注意：父节点下可以有多个子节点
