Yii2 Pagination and communication hasMany

[Oba22]

There's a sample of the species.

$category = Category::find()
            ->where( 'slug = :slug', [ ':slug' => $slug ] )
            ->with('items')
            ->one();

How is it right to organize a breakdown by page in this case without the use of dataProvider?

If I understood you correctly, it must be like,

$query = Category::find()
    ->where( 'slug = :slug', [ ':slug' => $slug ] )
    ->with('items');
$countQuery = clone $query;

$pages = new Pagination([

'totalCount' => $countQuery->count(),

'defaultPageSize' => 15,

]);
$categories = $query->offset($pages->offset)

->limit($pages->limit)

->all();

Well, there are categories and pages in mind, like Pagination's hands to work in a manuale on the website, like, examples.

update: http://www.yiiframework.com/doc-2.0/yii-data-pagination.html

update2: for certainty, renamed the outcome in categories, i.e., in view, foreach ($categories as $category) and within each foreach($category-graditems as $item)

update3:
Alternatively, when category one has to be visited by a range on its subjects: in that case, I suggest that the objects themselves be ploughed with a sample of the right category through the join:

$items = Item::find()->joinWith('category')->where('category.slug' => $slug)->all();

Next with the panic, it's the same as in the first option, and it's going to be the same way around the $items as $item. You can point out in the request if you have to pull something through the item-article-state... to avoid lazy underloads.
