yii\elasticsearch\ActiveDataProvider - Yii2 类参考手册
Class yii\elasticsearch\ActiveDataProvider
| Inheritance | yii\elasticsearch\ActiveDataProvider » yii\data\ActiveDataProvider » yii\data\BaseDataProvider » yii\base\Component » yii\base\BaseObject |
|---|---|
| Implements | yii\base\Configurable, yii\data\DataProviderInterface |
| Available since version | 2.0.5 |
ActiveDataProvider is an enhanced version of yii\data\ActiveDataProvider specific to the ElasticSearch.
It allows to fetch not only rows and total rows count, but full query results including aggregations and so on.
Note: this data provider fetches result models and total count using single ElasticSearch query, so 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\elasticsearch\yii\data\Pagination::validatePage automatically because of this.
