Yii2 ActiveDataProvider with leftJoin in query 不返回分页 pagesize items

如何解决Yii2 ActiveDataProvider with leftJoin in query 不返回分页 pagesize items

我试图在某个时间返回带薪水和注销的用户，并在每个页面返回 10 个项目，但它无法正常工作

我已尝试使用以下代码

          $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()]

当我检查 $data->getModels() 时，它只返回数组中的 3 个项目。我错过了什么

解决方法

问题：您的 ID 不是唯一的（将用作密钥）。主键将在您的结果中多次出现，并将被视为同一行。

克服这个问题：您将需要“分组依据”您的记录。也许为此使用 users.id。

$query = Users::find()
...
->groupBy(['users.id']);

如果 group by 不适合您，则需要指定行的键

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;

在你的情况下：

    $data = new ActiveDataProvider([
        'query' => $query,'pagination' =>[
            'pageSize' => 10,//here per_page is
            'page' => $arr['page']
        ],'key' => static function($model) {return [new unique key] }
    ]);
