Yii2-使用SqlDataProvider和GridView并启用Gridview筛选器进行搜索
我正在研究yii2。我有一个自定义视图，其中已放置视图DetailView和GridView。下面是我的控制器代码
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*/
]);
}
}
查看
<?php Pjax::begin(); ?>
<?= DetailView::widget([
'model' => $model,
'attributes' => [
[
'label'=>'Serial #',
'value' => function($d)
{
return $d->id;
}
],
[
'label' => 'Meter Type',
'value' => function ($d) {
if(is_object($d))
return $d->meter_type;
return ' - ';
},
],
'sub_div',
[
'label' => 'Sub Division Name',
'value' => function ($d) {
if(is_object($d))
return $d->subDiv->name;
return '-';
},
],
[
'label' => 'Prepared By',
'value' => function ($d) {
if(is_object($d))

['class' => 'yii\grid\SerialColumn'],
['class' => 'yii\grid\CheckboxColumn', 'checkboxOptions' => function($d) {
return ['value' => $d['meter_id']];
}],
'Meter_Serial_Number',
'Meter_Type',
'Sub_Division_Code',
'Sub_Division_Name',
],
]); ?>
<?php Pjax::end(); ?>
JS
$("#chk input:checkbox").prop("checked", true);
输出
在上面的grid view中，我想为Meter Serial Number添加搜索列，为Sub Division Name添加下拉列表。

更新3
更新代码后，我在Meter Serial和Sub Division上都得到了搜索过滤器
但是当我尝试搜索序列号时，页面会刷新，然后再次看到完整视图
通过echo $dataProvider->sql;，我得到
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.名称AS Sub_Division_Name FROM安装ins INNER JOIN米m ON ins. meter_msn = m. meter_msn INNER JOIN meter_acceptance_header map ON ins. meter_type = map. meter_type INNER JOIN调查sur ON ins. ref_no = sur. ref_no INNER JOIN调查_hesco_subdivision { {1}} sub_division sd ON sur. sub_div_code = sd. meter_type WHERE ins. sub_div_code = :meter_type AND sd. id = :sub_div AND map. meter_id NOT IN (SELECT DISTINCT md. meter_acceptance_details FROM标志{{1 }}
无论我是否搜索任何序列号，上面的查询都保持不变。
注意：我已经知道如何通过在搜索模型的计算列中添加过滤器字段来添加搜索选项。但是由于我有一个自定义视图，所以我很困惑该怎么办。
1 个答案:
答案 0 :(得分：3)
尽管我尚未在GridView中使用它，但如果有人可以提出建议，可能有比该解决方案更好的解决方案，但这可以按照您想要的方式工作。
您应该更新InstallationSearch模型以将过滤器与GridView一起使用。如果您未在任何地方使用默认InstallationSearch模型的search()函数，则可以更新现有的搜索方法，或者创建单独的方法。我假设您没有在其他任何地方使用它，我将添加一个搜索功能，该功能将使用SqlDataProvider来显示和过滤GridView。
要实现搜索，您需要确定要为列使用多少别名，必须将所有别名声明为搜索模型的public attributes
public $meter_id;
public $Meter_Serial_Number;
public $Meter_Type;
public $Sub_Division_Code;
public $Sub_Division_Name;
然后将它们添加到安全规则
public function rules() {
return [
[ [ 'meter_id' , 'Meter_Serial_Number' ,'Meter_Type','Sub_Division_Code','Sub_Division_Name'] , 'safe' ] ,
];
}
现在添加search()函数
public function searchInstallations($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 $dataProvider;
}
将您的actionViewcreated更新为以下
public function actionViewcreated($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' => $searchModel
]
);
}
并为如下所示的网格视图启用过滤器
[
'attribute'=>'Meter_Serial_Number',
'filter'=> \yii\helpers\Html::activeTextInput($searchModel, 'Meter_Serial_Number',['class'=>'form-control']),
],
[
'attribute' => 'Sub_Division_Name',
'filter'=> \yii\helpers\Html::activeTextInput($searchModel,'Sub_Division_Name', ['class'=>'form-control']),
],
EDIT
要使下拉菜单有效，请在其他地方未使用功能toArrayList()时将其更改为以下内容，或者创建单独的功能，因为需要将sub_div_name作为要搜索的值将该表更改为sub_div_code到具有sub_div_name的字段，我假设它是name中的SurveyHescoSubdivision字段。
/**
* @return mixed
*/
public static function toArrayList()
{
return ArrayHelper::map(
self::find()->all(), 'name', function ($model, $defaultValue) {
return $model['sub_div_code'] . ' - ' . $model['name'];
}
);
}
