Question

我需要按ID进行默认排序，我们不会在网格中显示ID，这就是为什么默认排序不起作用的原因是我的排序代码

public function search($params)
    {   
        $this->load($params);
        $query = new \yii\db\Query;
        $expression = new \yii\db\Expression('CASE WHEN b.status = 1 THEN "Active" WHEN  b.status = 2 THEN "Inactive" END AS status');
        $query->select(['b.image','bl.name',$expression,'b.brand_id'])  
              ->from('brand AS b')
              ->join('INNER JOIN', 
                    'brand_lang AS bl',
                    'bl.brand_id = b.brand_id AND lang_id = 1'); 

        $query->andFilterWhere([            
            'status' => $this->status,
        ]);
        $query->andFilterWhere(['like', 'name', $this->name]);

        $command = $query->createCommand();
        $data = $command->queryAll();       
        $dataProvider = new \yii\data\ActiveDataProvider([
            'query' => $query,
            'totalCount' => count($data),
            'sort' => [
                'attributes' => [
                    'name' => [
                        'asc' => ['name' => SORT_ASC, 'name' => SORT_ASC],
                        'desc' => ['name' => SORT_DESC, 'name' => SORT_DESC],
                        'default' => SORT_DESC,
                        'label' => 'Name',
                    ],
                    'status' => [
                        'asc' => ['status' => SORT_ASC, 'status' => SORT_ASC],
                        'desc' => ['status' => SORT_DESC, 'status' => SORT_DESC],
                        'default' => SORT_DESC,
                        'label' => 'Status',
                    ],
                    'brand_id' => [
                        'asc' => ['brand_id' => SORT_ASC, 'brand_id' => SORT_ASC],
                        'desc' => ['brand_id' => SORT_DESC, 'brand_id' => SORT_DESC],
                        'default' => SORT_ASC,
                        'label' => 'Brand',
                    ],
                    'defaultOrder' => ['brand_id' => SORT_ASC]
                ],
            ],
            'pagination' => [
                'pageSize' => 20,
            ],
        ]); 
        return $dataProvider;
    }

有谁能告诉我这是什么解决方案？我做了很多谷歌搜索，但没有取得成功

Answer 1

您的defaultOrder参数应位于sort，而不是attributes：

'sort' => [
    'attributes' => [...],
    'defaultOrder' => ['brand_id' => SORT_ASC],
],

Answer 2

使用$dataProvider->sort->attributes['attribute_name']：

$dataProvider = new ActiveDataProvider([
        'query' => $query,

        'sort' => [ 
            'defaultOrder' => ['brand_id' => SORT_ASC] 
        ],
    ]);

    $dataProvider->sort->attributes['name'] = [
        'asc' => ['name' => SORT_ASC],
        'desc' => ['name' => SORT_DESC],
    ];

Yii2默认排序不起作用
