yii2 一对多关系的对分页造成的影响

下面代码中关联descies时，匹配较多，造成分页数不对，需要加条件限制：

$model = User::find()
    ->joinWith('app')
    ->joinWith(['descies' => function($query){
        return $query->where(['user_desc_type_id'=>7]);
    }])
    ->where($condition)
    ->andFilterWhere($condition_pay_start)
    ->andFilterWhere($condition_sex);
$pagination = new Pagination([
    'defaultPageSize' => 10,
    'totalCount' => $model->count(),
]);

1.可在model中建立关联时限定：

1. public function getBooks()
2.     {
3.         return $this->hasMany(Item::className(), ['owner_id' => 'id'])->onCondition(['category_id' => 1]);
4.     }

　2.代码中限定：方法如上：
