Yii2-使用 SqlDataProvider 和 GridView 并启用 Gridview Filter 进行搜索
Yii2-Use SqlDataProvider with GridView and enable Gridview Filter for search
我正在研究 yii2。我有一个自定义视图，我在其中放置了视图 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;
}
],
[

'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 '-';
},
],
[

'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 添加搜索列并为 Sub Division Name 添加下拉列表。

更新 3
更新我的代码后，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，页面刷新了，我又看到了完整视图
通过 echo $dataProvider->sql; 我得到了
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 FROM安装ins INNER JOIN米m ON ins.meter_msn= m.meter_msnINNER JOINmeter_acceptance_headermap ON ins.meter_type= map.meter_typeINNER JOIN调查sur 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.标志IN (1)) AND ins.meter_msn like :meter_serial_number AND sd.sub_div_code like :sub_div_code
不管我是否搜索过任何序列号，上面的查询都是一样的。
注意：我已经知道如何通过在搜索模型的计算列中添加筛选字段来添加搜索选项。但是因为我有一个自定义视图，所以我很困惑我该怎么做。
虽然在 GridView 中我还没有完全使用过它，但如果有人能提出建议，可能会有比这个更好的解决方案，但这可以按照你想要的方式工作。
您应该更新您的 InstallationSearch 模型以使用带有 GridView 的过滤器。如果您没有在任何地方使用默认 InstallationSearch 模型的 search() 函数，那么您可以更新现有的搜索方法或创建一个单独的方法。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.
要实施搜索，您需要确定您为列使用了多少别名，您必须将所有别名声明为搜索模型 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 $dataProvider;
}
将您的 actionViewcreated 更新为以下内容
public function actionViewcreated($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' => $searchModel
]
);
}
并为网格视图启用过滤器，如下所示
[
'attribute'=>'Meter_Serial_Number',
'filter'=> \yii\helpers\Html::activeTextInput($searchModel, 'Meter_Serial_Number',['class'=>'form-control']),
],
[
'attribute' => 'Sub_Division_Name',
'filter'=> \yii\helpers\Html::activeTextInput($searchModel,'Sub_Division_Name', ['class'=>'form-control']),

EDIT
为了使您的下拉菜单正常工作，请将函数 toArrayList() 更改为以下内容（如果它未在其他任何地方使用），或者创建一个单独的函数，因为您需要将 sub_div_name 作为值在 table 中搜索，因此将 sub_div_code 更改为具有 sub_div_name 的字段，我假设它是 SurveyHescoSubdivision 中的 name 字段。
/**
* @return mixed
*/
public static function toArrayList()
{
return ArrayHelper::map(
self::find()->all(), 'name', function ($model, $defaultValue) {
return $model['sub_div_code'] . ' - ' . $model['name'];
}
);
}
我正在研究 yii2。我有一个自定义视图，我在其中放置了视图 DetailView 和 GridView。下面是我的控制器代码
public function actionViewcreated($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

INNER JOIN `meters` m ON ins.`meter_msn` = m.`meter_msn`
INNER JOIN `meter_acceptance_header` map ON ins.`meter_type` = map.`meter_type`

AND sd.`sub_div_code` = '$sub_div'

`meter_acceptance_details` md WHERE md.`flag` IN (1))";
$session = Yii::$app->session;
$session->set('my_sql', $query);

更新 3
更新我的代码后，我在 Meter Serial 和 Sub Division
但是当我尝试搜索序列号时，页面刷新了，我又看到了完整视图
通过 echo $dataProvider->sql; 我得到了
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 FROM安装ins INNER JOIN米m ON ins.meter_msn= m.meter_msnINNER JOINmeter_acceptance_headermap ON ins.meter_type= map.meter_typeINNER JOIN调查sur 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.标志IN (1)) AND ins.meter_msn like :meter_serial_number AND sd.sub_div_code like :sub_div_code
不管我是否搜索过任何序列号，上面的查询都是一样的。
注意：我已经知道如何通过在搜索模型的计算列中添加筛选字段来添加搜索选项。但是因为我有一个自定义视图，所以我很困惑我该怎么做。
虽然在 GridView 中我还没有完全使用过它，但如果有人能提出建议，可能会有比这个更好的解决方案，但这可以按照你想要的方式工作。
您应该更新您的 InstallationSearch 模型以使用带有 GridView 的过滤器。如果您没有在任何地方使用默认 InstallationSearch 模型的 search() 函数，那么您可以更新现有的搜索方法或创建一个单独的方法。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.
要实施搜索，您需要确定您为列使用了多少别名，您必须将所有别名声明为搜索模型 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,

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'],

$queryCount = "SELECT COUNT(DISTINCT m.`id`)

$dataProvider = new SqlDataProvider(

);
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';
}

$session->set('my_sql', Yii::$app->db->createCommand($query, $queryParams)->rawSql);

将您的 actionViewcreated 更新为以下内容

$model = $this->findModel($id); // this will find my model/record based on the id
$sub_div = $model->sub_div;

并为网格视图启用过滤器，如下所示
[
'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
为了使您的下拉菜单正常工作，请将函数 toArrayList() 更改为以下内容（如果它未在其他任何地方使用），或者创建一个单独的函数，因为您需要将 sub_div_name 作为值在 table 中搜索，因此将 sub_div_code 更改为具有 sub_div_name 的字段，我假设它是 SurveyHescoSubdivision 中的 name 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'];
}
);
}
