Why is filter not working in GridView in Yii2?

Question

Yii

Actually, the GridView filters in Yii2 do not work (there are no signs of life on my actions). My Code:
Controller

public function actionIndex()
    {
        $searchModel = new UserSearch();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

        return $this->render('index', [
            'searchModel' => $searchModel,
            'dataProvider' => $dataProvider,
        ]);
    }

Search model

public function search($params)
    {
        $query = StUsers::find();

        // add conditions that should always apply here

        $dataProvider = new ActiveDataProvider([
            'query' => $query,
        ]);

        $this->load($params);

        if (!$this->validate()) {
            // uncomment the following line if you do not want to return any records when validation fails
            // $query->where('0=1');
            return $dataProvider;
        }

        // grid filtering conditions
        $query->andFilterWhere([
            'id' => $this->id,
            'passport_number' => $this->passport_number,
            'passport_issue' => $this->passport_issue,
            'passport_validity' => $this->passport_validity,
            'dob' => $this->dob,
            'discount' => $this->discount,
            'block' => $this->block,
            'block_admin_id' => $this->block_admin_id,
            'register_date' => $this->register_date,
            'alive' => $this->alive,
        ]);

        $query->andFilterWhere(['like', 'fullname', $this->fullname])
            ->andFilterWhere(['like', 'passport_serie', $this->passport_serie])
            ->andFilterWhere(['like', 'passport_authority', $this->passport_authority])
            ->andFilterWhere(['like', 'sex', $this->sex])
            ->andFilterWhere(['like', 'residence_address', $this->residence_address])
            ->andFilterWhere(['like', 'phone_number', $this->phone_number])
            ->andFilterWhere(['like', 'password', $this->password])
            ->andFilterWhere(['like', 'email', $this->email])
            ->andFilterWhere(['like', 'block_reason', $this->block_reason]);

        return $dataProvider;
    }

Performance

<?php Pjax::begin(); ?>
    <?= GridView::widget([
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            'id',
            'fullname'
         ]); ?>
<?php Pjax::end(); ?>

Answer 1

the first is to add:

public function scenarios()
    {
        return Model::scenarios();
    }

it is obligatory to indicate the bonds from above:
Second:

// grid filtering conditions
        $query->andFilterWhere([
            'id' => $this->id,
        ]);

Remove all unnecessary.
This is the logic of Yii2 :)
