我有两个问题

我有三张桌子。tbl_目标城市、lib_城市和lib_省份

通过视频教程，我能够将tbl_目标城市的数据显示到gridview，并将其连接到lib_城市

gridview中的排序工作得很好，但城市/市政列除外，它来自关系

问题1:如何更正城市/直辖市列的排序

问题2:如何添加带有搜索框和功能排序功能的省栏

待确定目标城市

按升序排列的示例视图-（工作不正常）

按降序

  • 在网格搜索中添加以下代码

    //it's for sort by city name
$dataProvider->sort->attributes['cityName'] = [
    'asc' => ['lib_cities.cityName' => SORT_ASC],
    'desc' => ['lib_cities.cityName' => SORT_DESC],
];

// it's sort by prov_name
$dataProvider->sort->attributes['province'] = [
    'asc' => ['lib_provinces.prov_name' => SORT_ASC],
    'desc' => ['lib_provinces.prov_name' => SORT_DESC],
];
  • 在网格视图代码中添加以下代码

    [
        'attribute'=>'city_code',
        'value'=>'cityName.city_name',
        //'contentOptions'=>['style'=>'width: 120px;']
],
[
        'attribute'=>'province',
        'value'=>'cityName.province.prov_name',
        //'contentOptions'=>['style'=>'width: 120px;']
],
    • 我通过将
    search
    方法更改为以下内容来计算排序

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

    $query->joinWith('cityName');

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);


    $dataProvider->sort->attributes['city'] = [
    // The tables are the ones our relation are configured to
    // in my case they are prefixed with "tbl_"
    'asc' => ['lib_Cities.city_name' => SORT_ASC],
    'desc' => ['lib_Cities.city_name' => SORT_DESC],
];

    $this->load($params);

    if (!$this->validate()) {
        // uncomment the following line if you do not want to any records when validation fails
        // $query->where('0=1');
        return $dataProvider;
    }



    $query->andFilterWhere([
        'id' => $this->id,
        'grouping' => $this->grouping,
        'launch_year' => $this->launch_year,
    ]);

   /* $query->andFilterWhere(['like', 'city_code', $this->city_code])
        ->andFilterWhere(['like', 'kc_classification', $this->kc_classification])
        ->andFilterWhere(['like', 'cluster', $this->cluster])
        ->andFilterWhere(['like', 'priority', $this->priority]);   */

    $query->andFilterWhere(['like', 'kc_classification', $this->kc_classification])
        ->andFilterWhere(['like', 'cluster', $this->cluster])
        ->andFilterWhere(['like', 'priority', $this->priority])
        ->andFilterWhere(['like', 'lib_cities.city_name', $this->city_code]);

    return $dataProvider;
}
    参考资料：

    您只需添加$query->orderBy（'lib\u cities.city\u name ASC'）；这是可行的，但如果我点击另一个标题，它总是按lib_cities排序…好的。我在试你的密码，我有个错误<代码>SQLSTATE[42S22]：未找到列：1054未知列“lib_province.prov_name”在“order子句”中正在执行的SQL是：选择
    tbl_target_cities

    tbl_target_cities
    =
    lib_cities
    城市
