Yii2-使用模型属性进行Gridview排序

Question

In my model, i have tableName set to a database. I created a new attribute in the model called $fullname and defined it by joining with another table/model in my afterFind function like so:

public function afterFind()
{
    parent::afterFind();

    $temp = Yii::$app->db->createCommand("select last_name || ', ' || first_name as fullname from employees where EMP_ID = :emp_id");
    $temp->bindValues([':emp_id' => $this->EMP_ID]);
    $this->fullname = $temp->queryColumn()[0];
}

I am trying to figure out how I can use this model attribute in my gridview to sort by this fullname attribute.

I have tried

 $dataProvider->setSort([
    'attributes' => [
        'fullname' => [
            'asc' => ['fullname' => SORT_ASC],
            'desc' => ['fullname' => SORT_DESC],
            'label' => 'Full Name',
            'default' => SORT_ASC
        ]
    ]
    ]);

Can anyone tell me how I can sort by this attribute or an alternative to this solution?

You can use this :

$dataProvider->sort->attributes['fullname'] = [
    'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
    'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
    'default' => SORT_ASC
];
