Yii2, elasticsearch. How to assign my _id as primaryKey - elasticsearch

Question

i'm newbie so I hope you can help me.
I have yii2 and i need to implement elasticSearch(ES).
All set up.
I made standart model and standart CRUD. Just a few changes to implement ES like
use yii\elasticsearch\ActiveRecord;
But I have a problem with getting _id in my view/index.php
to get _id in view.php i made
$model->_id = $model->primaryKey;
But how I can fix it with DataProvider in index.php?
my attributes
public function attributes()
{
return [
'_id',
'first_name',
'last_name',
'email',
'created',
'brand',
'product',
'qty',
'sum'
];
}
My rules
public function rules()
{
return [
[['first_name', 'last_name', 'email', 'created',
'brand', 'product', 'qty', 'sum'
],
'safe'],
[['qty'], 'integer'],
[['sum'], 'double'],
['email', 'email'],
];
}
I think it should work like with MongoDB, but it doesn't.
if I want to delete or view or update the data being on index.php I can se only such links w/o id
http://yii2.dev/index.php?r=elastic%2Fdelete&id=
Pls help
P.S.
Here is a var_dump
array (size=5)
0 =>
object(frontend\models\Elastic)[67]
private '_id' (yii\elasticsearch\ActiveRecord) => string 'AVreA6SUvBgWLKxTzUZn' (length=20)

you can set.good luck
$dataProvider = new ActiveDataProvider([
'query' => $query,
'key' => ['your primaryKey']
'sort' => [
'defaultOrder' => ['datetime'=>SORT_DESC]
],
]);
