Yii2 - Union query with Pagination into ActiveRecord - yii

Question

I have a case where I need to have a union query, and at the same time have the end result as ActiveRecord. To illustrate, I have two tables Products and Categories. Each has a model that extends from ActiveRecord. I'm trying to have a query as follows
$deletedProducts = Products::find()->select([$productsTable . '.id', $productsTable . '.selling_price'])
->where(['client' => $clientId])
->andWhere(['<>', 'hidden', 0]);
and
$deletedCats = Category::find()->select([$catTable . '.id', $catTable . '.selling_price'])
->where(['client' => $clientId])
->andWhere(['<>', 'hidden', 0]);
and
$archivedItemsQuery = $deletedProducts->union($deletedCats);
I then return the results through ActiveDataProvider
$dataProvider = new ActiveDataProvider(
[
'query' => $archivedItemsQuery,
]
]);
return $dataProvider->getModels();
The problem is that when I try to send pagination data in the request, or set it through the ActiveDataProvider, no pagination happens. I can change this query of course to
$unionQuery = (new \yii\db\Query())
->from(['counter_items' => $archivedItemsQuery]);
This results in correct pagination, but I dont get the result as ActiveRecords.
Any ideas on how to create a union query with 1. Pagination working and 2. The result is ActiveRecord.

Hi can you try the following, not very neatest of the ways but I hope it works for you I tested it on my end and if I understand correctly you want the result of $dataProvider->getModels() to return an ActiveRecord Models Object i.e Products model and want the GridView pagination to work correctly at the same time.
You need to change the ActiveDataProvider to use the union $archivedItemsQuery in the following way.
$dataProvider = new \yii\data\ActiveDataProvider([
'query' => Products::find()->from(['products' => $archivedItemsQuery]),
'pagination' => [
'pageSize' => 10,
],
]);
