Question

我有一个显示公司数据的gridview。每家公司都有tehsil_id作为外键。下面是从父级到子级的表结构：

Country->province->city->district->tehsil

每家公司都位于特定的公司。可以使用tehsil ID向后追踪地区或城市或省份。

我面临的问题是，我想列出的公司不仅可以按Tehsil ID（公司表中的列）进行排序，还可以按城市ID /省ID /国家ID（这些ID都不是其中的一部分）排序公司表）。

我能够在gridview中列出这些相关的区/城市/省，但无法使用这些值进行排序。我们将不胜感激。

Answer 1

您只能对原始查询中存在的列进行排序。您很可能拥有CompanySearch类，其search()方法。在其中，将更多表连接到原始查询：

$query = Company::find()->joinWith([
    'tehsil',
    'tehsil.district',
    'tehsil.district.city',
    'tehsil.district.city.province',
    'tehsil.district.city.province.country'
]);

然后将新列添加到网格：

echo GridView::widget([
    ...
    'columns' => [
        'id',
        'name',
        'tehsil',
        'tehsil.district',
        'tehsil.district.city',
        'tehsil.district.city.province',
        'tehsil.district.city.province.country',
        ...

它们应该是可排序的。

另外，请查看本教程：Kivy rule inherence with add_widget()

Yii2排序间接相关的列，它不是gridview模型的一部分
