Yii2 添加相关属性进行排序

Question

我有普通的 ModelSearch 和 ActiveDataProvider，我想添加一个虚拟/相关属性来在 gridview 中排序。如果我使用 setSort 进行操作，并且仅添加此属性，则所有其他属性都不再可排序。是否有内置方法可以“添加”属性进行排序？非常感谢！

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

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
        'sort' => ['defaultOrder' => ['aonr' => SORT_ASC]],
        'pagination' => [
            'pageSize' => 15,
        ],
    ]);

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

$this->load($params);
...
}

要排序的列，而不仅仅是关系中的列。 如果您想添加一列，您可以尝试此操作（将当前现有的排序属性与新的排序属性合并）：

    $dataProvider->setSort([
        'attributes' => array_merge(
            $dataProvider->getSort()->attributes,
            [
                'lwnr' => [
                    'asc'     => ['lwnr' => SORT_ASC],
                    'desc'    => ['lwnr' => SORT_DESC],
                    'label'   => 'lwnr',
                    'default' => SORT_DESC,
                ],
            ]
        ),
    ]);

或者您可以手动添加缺少的属性/列（这是一个更好的主意）

    $dataProvider->setSort([
        'attributes' =>
            [
                'lwnr' => [
                    'asc'     => ['lwnr' => SORT_ASC],
                    'desc'    => ['lwnr' => SORT_DESC],
                    'label'   => 'lwnr',
                    'default' => SORT_DESC,
                ],
                // Other attribute
                'id'   => [
                    'asc'  => ['id' => SORT_ASC],
                    'desc' => ['id' => SORT_DESC],
                ],
                ...
            ],
    ]);

另一种方式：

$dataProvider->getSort()->attributes['lwnr'] = [
                    'asc'     => ['lwnr' => SORT_ASC],
                    'desc'    => ['lwnr' => SORT_DESC],
                    'label'   => 'lwnr',
                    'default' => SORT_DESC,
                ];
