Yii2 ActiveDataProvider with leftJoin in query doesnt return the pagination pagesize items - yii2

Question

Am trying to return users with paycheck and loggedout at a certain time and return 10 items per each page but it fails to work
I have tried with the following code
$filters = $arr["filters"];
$timev = [strtotime($filters["duration_from"]), strtotime($filters["duration_to"])]
$query = Users::find()
->leftJoin('tbl_truck_history', 'tbl_paychecks.user_id = users.id')
->leftJoin('tbl_security_login', 'tbl_security_login.user_id = users.id')
->where(["users.department"=>3])
->andWhere(['between', 'tbl_security_login.time_out', min($timev), max($timev)]);
$data = new ActiveDataProvider([
'query' => $query,
'pagination' =>[
'pageSize' => 10, //here per_page is
'page' => $arr['page']
],
]);
return ["data" => $data->getModels(),"totalRecords" => (int)$query->count()]
When i check on $data->getModels() it returns only 3 items in the array. What am i missing out

Answer 1

The problem:
Your ids are not unique (which will be used as a key). Primary key will appear multiple times in your result, and it will treated as a same row.
Overcome this problem:
You will need to "group by" your records. Maybe use users.id for this.
$query = Users::find()
...
->groupBy(['users.id']);
If group by is not an option for you, you will need to specify the key for the lines
class ActiveDataProvider extends BaseDataProvider
...
/**
* #var string|callable|null the column that is used as the key of the data models.
* This can be either a column name, or a callable that returns the key value of a given data model.
*
* If this is not set, the following rules will be used to determine the keys of the data models:
*
* - If [[query]] is an [[\yii\db\ActiveQuery]] instance, the primary keys of [[\yii\db\ActiveQuery::modelClass]] will be used.
* - Otherwise, the keys of the [[models]] array will be used.
*
* #see getKeys()
*/
public $key;
in your case:
$data = new ActiveDataProvider([
'query' => $query,
'pagination' =>[
'pageSize' => 10, //here per_page is
'page' => $arr['page']
],
'key' => static function($model) {return [new unique key] }
]);
