How to organize scope in Yii2?

Question

Yii

public function withFullUrl($url)
    {
        $this->getDbCriteria()->mergeWith(array(
            'condition'=>'full_url=:url',
            'params'=>array(':url'=>$url)
        ));

        return $this;
    }

This is how the method looked like in the Yii1 model, tell me about Yii2 please...

Start reading the docs already, this is the basis of the framework in general.
www.yiiframework.com/doc-2.0/guide-db-active-recor...

class Model extends ActiveRecord {
    public static function find() {
        return new MyQuery(get_called_class());
    }
}

class MyQuery extends ActiveQuery {
    public function withFullUrl($url) {
        $this->andWhere(['full_url' => $url]);
        return $this;
    }
}

Now the model and query are separated, so everything related to queries and the formation of this very query is in a separate class.
