Yii2 Pagination Issue on Union - pagination

Question

I am trying to use Pagination after union of two queries the pagination does not seems to work. However if I try to make one queries without union it works.
The below are the queries.Please help.
//First Query
$first_second = $this->find()->select($strcolumn.', p.featured_name')->from(MYDIRECTORY::tableName().' j')->join('INNER JOIN' ,MYDIRECTORYFEATUREDCLASS::tableName().' p', 'p.featurer_id = j.listdetails_featured_frid')->where(['listdetails_list_frid' => $id['list_id']])->andWhere(['<=', 'listdetails_featured_frid', 2])->andWhere(['listdetails_list_flag' => MYDIRECTORYCLASS::STATUS_ACTIVE])->orderBy(['listdetails_featured_frid'=>SORT_ASC,'listdetails_list_pos'=>new Expression('rand()')]);
//Second Query
$second_list = $this->find()->select($strcolumn.', p.featured_name')->from(MYDIRECTORYCLASS::tableName().' j')->join('INNER JOIN' ,MYDIRECTORYFEATUREDCLASS::tableName().' p', 'p.featurer_id = j.listdetails_featured_frid')->where(['listdetails_list_frid' => $id['list_id']])->andWhere(['>', 'listdetails_featured_frid', 2])->andWhere(['listdetails_list_flag' => MYDIRECTORYCLASS::STATUS_ACTIVE])->orderBy(['listdetails_featured_frid'=>SORT_ASC,'listdetails_list_medname'=>SORT_ASC]);
//Joined Union Query
$joinedquerys=$first_second->union($second_list);
$countQuery = clone $joinedquerys;
$pages = new Pagination(['totalCount' => $countQuery->count(), 'pageSize' => \Yii::$app->params['pagination_limit'],'defaultPageSize' => \Yii::$app->params['pagination_limit'],'forcePageParam' => false,'params' => ['page' => \Yii::$app->request->get('page', 1)] ]);
$resultArray = $joinedquerys->offset($pages->offset)->limit($pages->limit)->asArray()->all();
return $this->render('listing', [
"mylisting" => $resultArray,
"pagination" => $pages
]);
While using the pagination as below , the pagination seems to not work?Any help will be greatly appreciated
echo LinkPager::widget([
'pagination' => $pagination,
'options' => ['class' => 'paginate pag2 clearfix'],
'registerLinkTags' => true,
'prevPageLabel' => \YII::$app->params['linker_page_btn_prev'],
'nextPageLabel' => \YII::$app->params['linker_page_btn_next'],
'maxButtonCount' => \YII::$app->params['linker_page_btn_count'],
'activePageCssClass' => 'current',
'nextPageCssClass' => 'next'
]);

Answer 1

you could use dataProvider
<?php
$joinedquerys=$first_second->union($second_list);
$dataProvider = new SqlDataProvider([
'sql' => $joinedquerys,
]);
?>

Answer 2

I had the same problem, but in addition I had to use the ActiveDataProvider. To achieve this I had to do the following:
$joinedQuery = $first_second->union($second_list);
$dirQuery = MYDIRECTORY::find()->from(['directories' => $joinedQuery]);
$provider = new ActiveDataProvider([
'query' => $dirQuery,
]);
Hope this helps someone :)
