ActiveDataProvider is an enhanced version of yii\data\ActiveDataProvider specific to the Sphinx.
It allows to fetch not only rows and total rows count, but also a meta information and facet results.
The following is an example of using ActiveDataProvider to provide facet results:
$provider = new ActiveDataProvider([ 'query' => Post::find()->facets(['author_id', 'category_id']), 'pagination' => [ 'pageSize' => 20, ], ]); // get the posts in the current page $posts = $provider->getModels(); // get all facets $facets = $provider->getFacets(); // get particular facet $authorFacet = $provider->getFacet('author_id');
In case yii\sphinx\Query::showMeta() is set ActiveDataProvider will fetch total count value from the query meta information, avoiding extra counting query:
$provider = new ActiveDataProvider([ 'query' => Post::find()->showMeta(true), 'pagination' => [ 'pageSize' => 20, ], ]); $totalCount = $provider->getTotalCount(); // fetched from meta information
Note: when using 'meta' information results total count will be fetched after pagination limit applying, which eliminates ability to verify if requested page number actually exist. Data provider disables yii\data\Pagination::validatePage
automatically in this case.
Note: because pagination offset and limit may exceed Sphinx 'max_matches' bounds, data provider will set 'max_matches' option automatically based on those values. However, if yii\sphinx\Query::showMeta() is set, such adjustment is not performed as it will break total count calculation, so you'll have to deal with 'max_matches' bounds on your own.
