Yii2数据提供程序默认排序 - Yii2 data provider default sorting

在Yii 1.1中，此代码适用于默认排序：

$dataProvider = new CActiveDataProvider('article',array(
    'sort'=>array(
        'defaultOrder'=>'id DESC',
    ),
));

如何在Yii2中设置默认排序？

尝试了以下代码，但没有结果：

$dataProvider = new ActiveDataProvider([
    'query' => $query,
    'sort' => ['defaultOrder'=>'topic_order asc']
]);

我认为有合适的解决方案。配置yii'data'Sort对象：

 $dataProvider = new ActiveDataProvider([
     'query' => $query,
     'sort'=> ['defaultOrder' => ['topic_order' => SORT_ASC]],
 ]);

官方文档链接

或

       $dataProvider->setSort([
        'defaultOrder' => ['topic_order'=>SORT_DESC],
        'attributes' => [...

defaultOrder包含一个数组，其中键是列名，值是SORT_DESC或SORT_ASC，这就是下面代码不起作用的原因。

$dataProvider = new ActiveDataProvider([
        'query' => $query,
        'sort' => ['defaultOrder'=>'topic_order asc']
    ]);

正确的方式

$dataProvider = new ActiveDataProvider([
    'query' => $query,
    'sort' => [
        'defaultOrder' => [
            'topic_order' => SORT_ASC,
        ]
    ],
]);

注意：如果查询已经指定了orderBy子句，则最终用户（通过排序配置）给出的新排序指令将附加到现有的orderBy子句中。任何现有的限制和偏移子句都将被来自最终用户的分页请求覆盖（通过分页配置）。

您可以详细了解Yii2数据提供商指南

排序通过在查询中传递排序对象

 $sort = new Sort([
        'attributes' => [
            'age',
            'name' => [
                'asc' => ['first_name' => SORT_ASC, 'last_name' => SORT_ASC],
                'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
                'default' => SORT_DESC,
                'label' => 'Name',
            ],
        ],
    ]);
    $models = Article::find()
        ->where(['status' => 1])
        ->orderBy($sort->orders)
        ->all();

如果您有CRUD（索引），并且您需要为GridView、ListView或更多设置默认排序控制器。。。示例

public function actionIndex()
{
    $searchModel = new NewsSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
    // set default sorting
    $dataProvider->sort->defaultOrder = ['id' => SORT_DESC];
    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}

你需要添加

$dataProvider->sort->defaultOrder = ['id' => SORT_DESC];

尝试这个

$dataProvider = new ActiveDataProvider([
    'query' => $query,
]);
$sort = $dataProvider->getSort();
$sort->defaultOrder = ['id' => SORT_ASC];
$dataProvider->setSort($sort);

$dataProvider = new ActiveDataProvider([ 
    'query' => $query, 
    'sort'=> ['defaultOrder' => ['iUserId'=>SORT_ASC]] 
]);

您可以使用类似的排序属性

$dataProvider = new ActiveDataProvider([
 'query' => $query,
 'sort'=> ['defaultOrder' => ['topic_order' => SORT_ASC]],]);

如果你想为examle topic_order1和topic_older2按两个feild排序，你可以这样做

$dataProvider = new ActiveDataProvider([
 'query' => $query,
 'sort'=> ['defaultOrder' => ['topic_order1' => SORT_ASC,
'topic_order2' =>SORT_DESC]]]);

如指南中所述，您必须通过配置其排序属性来指定数据提供程序的排序行为，该属性与yii''data''sort 的配置相对应

$dataProvider = new ActiveDataProvider([
         'query' => $query,
         'sort'=> ['defaultOrder' => ['topic_order' => SORT_ASC]],
     ]);

    $modelProduct       =   new Product();
    $shop_id            =   (int)Yii::$app->user->identity->shop_id;
    $queryProduct       =   $modelProduct->find()
                            ->where(['product.shop_id'  => $shop_id]);

    $dataProviderProduct    =   new ActiveDataProvider([
                                    'query'         =>  $queryProduct,
                                     'pagination' => [ 'pageSize' => 10 ],
                                    'sort'=> ['defaultOrder' => ['id'=>SORT_DESC]]
                                ]);

您可以修改类似的搜索模型

$dataProvider = new ActiveDataProvider([
        'query' => $query,
        'sort' => [
            'defaultOrder' => ['user_id ASC, document_id ASC']
        ]
    ]);
