我有2个问题...

我有 3 张桌子。tbl_target_cities、lib_cities 和 lib_provinces。

通过遵循视频教程,我能够将 tbl_target_cities 中的数据显示到 gridview 并将其连接到 lib_cities。

除了来自关系的 CITY/MUNICIPALITY 列之外,gridview 中的排序非常有效。

问题 1:如何更正 CITY/MUNICIPALITY 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份列?

tbl_target_cities

我通过将search方法更改为以下来计算排​​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;
}

  1. 在您的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],
    ];
    
  2. 在您的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;']
    ],
