Yii2-Use SqlDataProvider with GridView and enable

问题:

I am working on yii2. I have a custom view in which I have placed to views DetailView and GridView. Below is my controller code

public function actionViewcreated($id)// passed the id of my model which is created in the previous step
{
    $model=$this->findModel($id); // this will find my model/record based on the id

    $sub_div = $model->sub_div;
    $meter_type = $model->meter_type;

    $query = "SELECT DISTINCT m.`id` AS meter_id, ins.`meter_msn` AS Meter_Serial_Number, ins.`meter_type` AS Meter_Type, sd.`sub_div_code` AS Sub_Division_Code,sd.`name` AS Sub_Division_Name 
    FROM `installations` ins 
    INNER JOIN `meters` m ON ins.`meter_msn` = m.`meter_msn`
    INNER JOIN `meter_acceptance_header` map ON ins.`meter_type` = map.`meter_type`
    INNER JOIN `survey` sur ON ins.`ref_no` = sur.`ref_no` 
    INNER JOIN `survey_hesco_subdivision` sd ON sur.`sub_division` = sd.`sub_div_code` 
    WHERE ins.`meter_type` = '$meter_type' 
    AND sd.`sub_div_code` = '$sub_div' 
    AND map.`id` NOT IN (SELECT DISTINCT md.`meter_id` FROM 
    `meter_acceptance_details` md WHERE md.`flag` IN (1))";


    $session = Yii::$app->session;
    $session->set('my_sql', $query);

    $count = Yii::$app->db->createCommand("SELECT COUNT(DISTINCT m.`id`)  
    FROM `installations` ins 
    INNER JOIN `meters` m ON ins.`meter_msn` = m.`meter_msn`
    INNER JOIN `meter_acceptance_header` map ON ins.`meter_type` = map.`meter_type` 
    INNER JOIN `survey` sur ON ins.`ref_no` = sur.`ref_no` 
    INNER JOIN `survey_hesco_subdivision` sd ON sur.`sub_division` = sd.`sub_div_code` 
    WHERE ins.`meter_type` = '$meter_type' 
    AND sd.`sub_div_code` = '$sub_div' 
    AND map.`id` NOT IN (SELECT DISTINCT md.`meter_id` FROM `meter_acceptance_details` md WHERE md.`flag` IN (1))")->queryScalar();

    $session = Yii::$app->session;
    $session->set('total', $count);


    if($count <= 0)
    {
        $this->findModel($id)->delete();

        \Yii::$app->getSession()->setFlash('errors', '
 <div class="alert alert-error alert-dismissable">
 <button aria-hidden="true" data-dismiss="alert" class="close" type="button">×</button>
 <strong>There are no meters installed against the selected Sub Division!!!! </strong>Acceptance is not Created</div>');


        return $this->redirect(['index', 'id' => $model->id]);
    }
    else
    {
        $dataProvider = new SqlDataProvider([
            'sql' => $query,
            'totalCount' => $count,
            'pagination' => [
                'pageSize' => 40,
            ],
        ]);


        return $this->render('viewcreated', [
            'dataProvider' => $dataProvider,
            'model' => $model,
            'id' => $model->id
            /*'searchModel' => $searchModel*/
        ]);
    }
}

]); ?>
 <?php Pjax::end(); ?>

JS

 $("#chk input:checkbox").prop("checked", true);

Output

In the above grid view I want to add search column for Meter Serial Number and dropdown for Sub Division Name.

How can I add these two options in the grid view?

Any help would be highly appreciated.

Update 3

After updating my code I got search filters on both the Meter Serial and Sub Division

But when I try to search a serial number then the page got refreshed and again I see the full view

By echo $dataProvider->sql; I got

SELECT DISTINCT m.idAS meter_id, ins.meter_msnAS Meter_Serial_Number, ins.meter_typeAS Meter_Type, sd.sub_div_codeAS Sub_Division_Code, sd.nameAS Sub_Division_Name FROMinstallationsins INNER JOINmetersm ON ins.meter_msn= m.meter_msnINNER JOINmeter_acceptance_headermap ON ins.meter_type= map.meter_typeINNER JOINsurveysur ON ins.ref_no= sur.ref_noINNER JOINsurvey_hesco_subdivisionsd ON sur.sub_division= sd.sub_div_codeWHERE ins.meter_type= :meter_type AND sd.sub_div_code= :sub_div AND map.idNOT IN (SELECT DISTINCT md.meter_idFROMmeter_acceptance_detailsmd WHERE md.flagIN (1)) AND ins.meter_msn like :meter_serial_number AND sd.sub_div_code like :sub_div_code

The above query remains the same whether I have searched for any serial number or not.

Note: I already know how to add a search option by adding a filter field in a calculated column in my search model. But as I have a custom view so I am confused that how can I do it.

回答1:

I have'nt used it quite though with the GridView and there could be better solutions than this one if anyone could suggest but this can work the way you want.

You should update your InstallationSearch model to use the filter with the GridView.If you are not using the default InstallationSearch model's search() function anywhere then you can update the existing search method or else create a separate method. I assume you are not using it anywhere else and I will add a search function that will use the SqlDataProvider for displaying and filtering the GridView.

To implement the search you need to identify how many aliases are you using for the columns you have to declare all of them as public attributes of your search model

public $meter_id;
public $Meter_Serial_Number;
public $Meter_Type;
public $Sub_Division_Code;
public $Sub_Division_Name;

then add them to the safe rule

public function rules() {
        return [
                [ [ 'meter_id' , 'Meter_Serial_Number' ,'Meter_Type','Sub_Division_Code','Sub_Division_Name'] , 'safe' ] ,
        ];
}

Now add the search() function

public function searchInstallations($params)
{
    $query = "SELECT DISTINCT
            m.`id` AS meter_id,
            ins.`meter_msn` AS Meter_Serial_Number,
            ins.`meter_type` AS Meter_Type,
            sd.`sub_div_code` AS Sub_Division_Code,
            sd.`name` AS Sub_Division_Name
            FROM `installations` ins
            INNER JOIN `meters` m ON ins.`meter_msn` = m.`meter_msn`
            INNER JOIN `meter_acceptance_header` map ON ins.`meter_type` = map.`meter_type`
            INNER JOIN `survey` sur ON ins.`ref_no` = sur.`ref_no`
            INNER JOIN `survey_hesco_subdivision` sd ON sur.`sub_division` = sd.`sub_div_code`
            WHERE ins.`meter_type` = :meter_type
            AND sd.`sub_div_code` = :sub_div
            AND map.`id` NOT IN (SELECT DISTINCT md.`meter_id` FROM
            `meter_acceptance_details` md WHERE md.`flag` IN (1))";

    $queryParams = [
        ':meter_type' => $params['meter_type'],
        ':sub_div' => $params['sub_div']
    ];

    $queryCount = "SELECT COUNT(DISTINCT m.`id`)
                FROM `installations` ins
                INNER JOIN `meters` m ON ins.`meter_msn` = m.`meter_msn`
                INNER JOIN `meter_acceptance_header` map ON ins.`meter_type` = map.`meter_type`
                INNER JOIN `survey` sur ON ins.`ref_no` = sur.`ref_no`
                INNER JOIN `survey_hesco_subdivision` sd ON sur.`sub_division` = sd.`sub_div_code`
                WHERE ins.`meter_type` = :meter_type
                AND sd.`sub_div_code` = :sub_div
                AND map.`id` NOT IN (SELECT DISTINCT md.`meter_id` FROM `meter_acceptance_details` md WHERE md.`flag` IN (1))";

    $dataProvider = new SqlDataProvider(
        [
            'sql' => $query,
            'pagination' => [
                'pageSize' => 40
            ]
        ]
    );

    if (!($this->load($params) && $this->validate())) {
        $dataProvider->params = $queryParams;
        $count = Yii::$app->db->createCommand($queryCount, $queryParams)->queryScalar();
        $dataProvider->totalCount = $count;
        return $dataProvider;
    }

    if ($this->Meter_Serial_Number !== '') {
        $dataProvider->sql .= ' AND ins.meter_msn like :meter_serial_number';
        $queryParams[':meter_serial_number'] = $this->Meter_Serial_Number . '%';
        $queryCount .= ' AND ins.meter_msn like :meter_serial_number';
    }

    if ($this->Sub_Division_Code !== '') {
        $dataProvider->sql .= ' AND sd.sub_div_code like :sub_div_code';
        $queryParams[':sub_div_code'] = $this->Sub_Division_Code . '%';
        $queryCount .= ' AND sd.sub_div_code like :sub_div_code';
    }

    $count = Yii::$app->db->createCommand($queryCount, $queryParams)->queryScalar();

    $dataProvider->totalCount = $count;
    $dataProvider->params = $queryParams;

    //add to session
    $session = Yii::$app->session;
    $session->set('my_sql', Yii::$app->db->createCommand($query, $queryParams)->rawSql);
    $session->set('total', $count);

    //return data provider
    return $dataProvider;
}

Update your actionViewcreated to the following

public function actionViewcreated($id)
{
    // passed the id of my model which is created in the previous step
    $model = $this->findModel($id); // this will find my model/record based on the id
    $sub_div = $model->sub_div;
    $meter_type = $model->meter_type;

    $queryParams = Yii::$app->request->queryParams;
    $queryParams['sub_div'] = $sub_div;
    $queryParams['meter_type'] = $meter_type;

    $searchModel = new InstallationSearch();
    $dataProvider = $searchModel->searchInstallation($queryParams);

    if (Yii::$app->session->get('total') <= 0) {
        $this->findModel($id)->delete();

        \Yii::$app->getSession()->setFlash(
            'errors',
            '<div class="alert alert-error alert-dismissable"><button aria-hidden="true" data-dismiss="alert" class="close" type="button">×</button>
            <strong>There are no meters installed against the selected Sub Division!!!! </strong>Acceptance is not Created</div>'
        );

        return $this->redirect(['index', 'id' => $model->id]);
    }

    return $this->render(
        'viewcreated', [
            'dataProvider' => $dataProvider,
            'model' => $model,
            'id' => $model->id,
            'searchModel' => $searchModel
        ]
    );
}

and enable the filter for the grid view like below

[
    'attribute'=>'Meter_Serial_Number',
    'filter'=> \yii\helpers\Html::activeTextInput($searchModel, 'Meter_Serial_Number',['class'=>'form-control']),
],
[
    'attribute' => 'Sub_Division_Name',
    'filter'=> \yii\helpers\Html::activeTextInput($searchModel,'Sub_Division_Name', ['class'=>'form-control']),
],

EDIT

For making your dropdown work either change the function toArrayList() to the following if it is not used anywhere else or create a separate function as you need to have the sub_div_name as the value to be searched in the table so change the sub_div_code to the field which has the sub_div_name i assume it is the name field in the SurveyHescoSubdivision .

/**
 * @return mixed
 */
public static function toArrayList()
{
    return ArrayHelper::map(
        self::find()->all(), 'name', function ($model, $defaultValue) {
            return $model['sub_div_code'] . ' - ' . $model['name'];
        }
    );
}
