Sort and filter data in GridView Yii2 where column is not in database

Question

If I have 2 fields in db - probability and influence and I need a column in GridView where these two fields are multiplied. I managed to add it there like:

Answer 1

Removed

      $query->select('*, (probability * influence) as priority');

changed

          'priority' => [
                'asc' => ['(probability * influence)' => SORT_ASC],
                'desc' => ['(probability * influence)' => SORT_DESC],
                'label' => 'Priority',
              ],

and after $this->load($params);

          $query->andFilterWhere(['=', '(probability * influence)', $this->priority]);

And search works as needed! :)

Thanks for help!
