Question

我正在搜索四个表并加入它们并获得我想要的输出。但无法对输出进行排序或过滤。请告诉我如何按地区或销售范围或收集范围进行搜索。缔约方搜索模型是 -

在这张图片中，我们可以看到尽管销售排序存在，但实际上并没有对数据进行排序。在图2中，我们可以看到虽然数据assam被传递到kartik expandrow的下一级，但它并没有过滤。

Answer 1

根据yii2's docs您使用内置ActiveDataProvider的{{1}}。这是the example docs page的案例。

我认为您要做的是ActiveRecord，而不仅仅是return $dataProvider->getModels()。这可能会返回所有行，因为我没有看到分页机制（可能有默认的分页计数）。

对于排序，您可以尝试对return $dataProvider而不是$query进行排序。尝试类似：

$dataProvider

Answer 2

使用数据提供者和过滤器模型设置网格视图。

在您看来：

<?= GridView::widget([
    'dataProvider'=> $dataProvider,
    'filterModel' => $searchModel,
    'columns' => [
        'parties_partyname', 
        'address', 
        'parties_district', 
        'name_manager', 
        'transport', 
        'dlno', 
        'instruction', 
        'con', 
        'district',
        'sale',
        'sell',
        'collection'
    ]
]); ?>

在您的控制器中（将index替换为您的视图文件的名称）：

$searchModel = new \frontend\modules\districtreport\models\PartiesSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);

return $this->render('index', [
    'searchModel' => $searchModel,
    'dataProvider' => $dataProvider,
]);

尝试从搜索模型中删除$dataProvider->setSort()。

此外，在您的gridview详细信息中，您对搜索模型和数据提供者使用相同的变量名称。它们是两个独立的模型，因此变量不应该相同。

Answer 3

根据http://www.yiiframework.com/doc-2.0/yii-db-activerecord.html#findBySql%28代码，findbysql无法排序或过滤。但是，可以通过在页面后面构建查询来感受它 - http://www.yiiframework.com/doc-2.0/guide-db-query-builder.html 查询将类似于 -

$subQuery1 = (new Query())->select(['parties_district','billdate','sum(billamount) as sale'])->from ('parties')->join('LEFT JOIN','bills','bills.bills_partyname = parties.parties_partyname')->groupby('parties_district')->where('billdate != "NULL"');        
        $subQuery2 = (new Query())->select(['district','coalesce(sell.sale,0) as totalsale'])->from('districts')->leftJoin(['sell' => $subQuery1],'sell.parties_district = districts.district'); 
        $subQuery3 = (new Query())->select(['parties_district','payment_date','COALESCE(sum(payment_amount),0) as collection'])->from('payment')->join('LEFT JOIN','parties','payment.payment_partyname = parties.parties_partyname')->groupby('parties_district');
        $query = (new Query())->select(['tsell.district as district','tsell.totalsale as sell','coalesce(tcollection.collection,0) as collection'])->from(['tsell'=> $subQuery2])->leftJoin(['tcollection' => $subQuery3],'tcollection.parties_district = tsell.district');

Answer 4

这些年来，任何人都应该遇到这个问题：如果您将它们传递给findBySql方法，则该查询将可以可排序（分页也可以，不适用于ActiveDataProvider + findBySql）。到ArrayDataProvider而不是ActiveDataProvider，如下所示：

$query = MyModel::findBySql("SELECT * FROM ...");
$dataProvider = new ArrayDataProvider([
    'allModels' => $query->all(),
    'sort' => [
        'attributes' => [
            'model_id',
            'model_name'
        ],
        'defaultOrder' => [
            'model_name' => SORT_ASC
        ]
    ],
    'pagination' => [
        'pageSize' => 30
    ]
]);

传统的过滤方法不起作用。来自findBySql() docs：

请注意，由于已经指定了SQL语句，因此在创建的yii \ db \ ActiveQuery实例上调用其他查询修改方法（例如where（），order（））将无效。

我想出了一种解决方法，它比使用接口方法需要更多的工作，但是对于复杂的查询（我认为这是您尝试使用findBySql的原因），它可以工作：

public function search($params)
{
    $this->load($params);

    $filters = [];

    if ($this->model_id) $filters[] = ' "table"."model_id" = '.$this->model_id.' ';
    if ($this->model_name) $filters[] = ' "table"."model_name" ILIKE \'%'.$this->model_name.'%\' ';

    // ugly ifs can be put into a foreach if you don't need to customize each condition too much

    $filterCondition = count($filters) > 0 ? ' AND ' . implode(' AND ', $filters) : ' ';

    $query = MyModel::findBySql(
        // your query here
        .$filterCondition.
        // group by, order by etc.
    );

    // assemble the ArrayDataProvider (see above)

    return $dataProvider;
}

Yii版本：2.0.34，PHP版本：7.3.18，PostgreSQL版本：12.2

当我在yii2中使用findbysql查询时排序和搜索列
