[英]How do I add a filter on yii2 models
I have a query used to read data from a view.我有一个用于从视图中读取数据的查询。 I am then applying a non related sql filter to this, to take out the models I don't need and then returning an arrayDataProvider instance.然后我对此应用一个不相关的 sql 过滤器,取出我不需要的模型,然后返回一个 arrayDataProvider 实例。 The filter I am applying is the promotion period.我应用的过滤器是促销期。 However, when I pass query params to this search model, it doesn't work.但是,当我将查询参数传递给此搜索 model 时,它不起作用。 How do I solve this?我该如何解决这个问题?
Here's the code to select data from the view:这是视图中 select 数据的代码:
public function search($params, $promotion_period)
{
$query = StaffEmploymentListView::find()->alias('LIST')
->joinWith(['employment EMPLOYMENT'])
->where(['LIST.EMPLOYMENT_TYPE' => 'PROMOTION']);
$query->andFilterWhere(['like', 'DEPT_NAME', $this->DEPT_NAME])
->andFilterWhere(['like', 'COL_NAME', $this->COL_NAME])
->andFilterWhere(['like', 'GRADE_DESCR', $this->GRADE_DESCR])
->andFilterWhere(['like', 'DESG_NAME', $this->DESG_NAME])
->andFilterWhere(['like', 'TRIBE_NAME', $this->TRIBE_NAME])
->andFilterWhere(['like', 'GENDER', $this->GENDER])
->andFilterWhere(['like', 'HOME_DISTRICT', $this->HOME_DISTRICT]);
$allModels = [];
if($promotion_period !== null){
$to_date = strtotime($promotion_period['to_date']);
$from_date = strtotime($promotion_period['from_date']);
foreach ($query->all() as $model)
{
$effective_date = strtotime($model->employment->APPOINT_DATE);
if ($effective_date >= $from_date && $effective_date <= $to_date){
$allModels[] = $model;
}
}
}
else{
foreach ($query->all() as $model)
{
$allModels[] = $model;
}
}
$dataProvider = new ArrayDataProvider([
'allModels' => $allModels,
'pagination' => [
'pageSize' => 20,
],
'sort' => false
]);
$this->load($params);
if (!$this->validate()) {
return $dataProvider;
}
return $dataProvider;
}
Here's the dump of the params from the URL:这是来自 URL 的参数转储:
[
'from_date' => ''
'to_date' => ''
'PromotedStaffSearch' => [
'COL_NAME' => 'CENTRAL ADMINISTRATION'
'DEPT_NAME' => ''
'GRADE_DESCR' => ''
'DESG_NAME' => ''
'GENDER' => ''
'TRIBE_NAME' => ''
'HOME_DISTRICT' => ''
]
] ]
Like i understand, you trying to find all models between
specified period if it is set.就像我理解的那样,如果已设置,您将尝试查找指定时间段between
的所有模型。
Try this:尝试这个:
public function search($params, $promotion_period)
{
$query = StaffEmploymentListView::find()->alias('LIST')
->joinWith(['employment']) //Here should be your relation name from StaffEmploymentListView model
->where(['LIST.EMPLOYMENT_TYPE' => 'PROMOTION']);
$dataProvider = new ActiveDataProvider([
'query' => $query,
'pagination' => [
'pageSize' => 20,
],
'sort' => false
]);
$this->load($params);
if (!$this->validate()) {
return $dataProvider;
}
$query->andFilterWhere(['like', 'DEPT_NAME', $this->DEPT_NAME])
->andFilterWhere(['like', 'COL_NAME', $this->COL_NAME])
->andFilterWhere(['like', 'GRADE_DESCR', $this->GRADE_DESCR])
->andFilterWhere(['like', 'DESG_NAME', $this->DESG_NAME])
->andFilterWhere(['like', 'TRIBE_NAME', $this->TRIBE_NAME])
->andFilterWhere(['like', 'GENDER', $this->GENDER])
->andFilterWhere(['like', 'HOME_DISTRICT', $this->HOME_DISTRICT]);
//$allModels = [];
if(is_array($promotion_period) && isset($promotion_period['to_date']) && isset($promotion_period['from_date'])){
//also check if you $promotion_period params are not empty
$to_date = strtotime($promotion_period['to_date']);
$from_date = strtotime($promotion_period['from_date']);
$query->andFilterWhere(['BETWEEN', 'EMPLOYMENT_TABLE_NAME.APPOINT_DATE', $from_date, $to_date]);
}
//Now you can get all your filtered models as array like this:
return $dataProvider->getModels();
}
