Yii2 gridview日期范围选取器筛选器不起作用

我已将kartik-v日期范围选择器添加到我的gridview中，但在我选择日期后，过滤器无法工作。小部件的占位符将显示所选日期，但gridview中的结果不匹配。gridview中的结果显示所有数据

视图中的代码：

<?= GridView::widget([
    'options' => ['class' => 'table-sm'],
    'filterModel' => $searchModel,
    'dataProvider' => $dataProvider,
    'summary' =>'',
    'columns' => [
        [
            'attribute' => 'price',
            'value' => function ($model) {
                return number_format($model->price, 3);
            },
            'contentOptions' => ['class' => 'text-right']
        ],
        [
            'attribute' => 'date',
            'contentOptions' => ['class' => 'text-right'],
            'filter' => DateRangePicker::widget([
                'name'=>'date_range_2',
                'presetDropdown'=>true,
                'convertFormat'=>true,
                'includeMonthsFilter'=>true,
                'attribute' => 'date',
                'model' => $searchModel,
                'pluginOptions' => ['locale' => ['format' => 'Y-m-d']],
                'options' => ['placeholder' => 'Select Date']
            ])
        ],
    ]
]); ?>

DateRangePicker本身为您提供了一个包含范围的字符串，因此带有“date”=>$this->date的简单where子句无法工作。Kartik V.在程序包Kartik-V/yii2日期范围中提供行为Kartik\daterange\DateRangeBehavior

我正在以以下方式成功地使用它。请注意，我的timestamp属性是timestamp\u visit

他认为：

echo GridView::widget([
...
    'columns' => [
        [
            'attribute' => 'timestamp_visit',
            'format' => [
                'datetime',
                'medium'
            ],
            'width' => '60px',
            'filterType' => GridView::FILTER_DATE_RANGE,
            'filterWidgetOptions' => [
                'model' => $searchModel,
                'convertFormat' => true,
                'pluginOptions' => [
                    'timePicker' => true,
                    'timePickerIncrement' => 1,
                    'timePicker24Hour' => true,
                    'locale' => [
                        'format' => $searchModel::TIME_FORMAT,
                    ]
                ]
            ]
        ],
    ...
    ]

在搜索模型中：

<?php
...
use kartik\daterange\DateRangeBehavior;

class ...Search extends ....
{
    const TIME_FORMAT = 'Y-m-d H:i:s';

    /**
     * @var string Start date filled up by DateRangeBehavior
     */     
    public $timestampVisitStart;

    /**         
     * @var string End date filled up by DateRangeBehavior
     */         
    public $timestampVisitEnd;
...

       public function rules()
    {
        return [
            [['timestamp_visit'], 'match', 'pattern' => '/^.+\s\-\s.+$/'],
            ...
        ];
    } 
    public function behaviors()
    {
        return [
            [
                'class' => DateRangeBehavior::class,
                'attribute' => 'timestamp_visit',
                'dateStartAttribute' => 'timestampVisitStart',
                'dateEndAttribute' => 'timestampVisitEnd',
                'dateStartFormat' => self::TIME_FORMAT,
                'dateEndFormat' => self::TIME_FORMAT,
            ]
        ];
    }
...
    public function search($params)
    {
        $query = self::find();

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

        $dataProvider->sort = new Sort([
            'defaultOrder' => [
                'timestamp_visit' => SORT_DESC,
                'id' => SORT_DESC,
            ]
        ]);
...
        if ($this->timestampVisitStart) {
            $query->andWhere(['>=', "timestamp_visit", $this->timeToUTC($this->timestampVisitStart)]);
        }
        if ($this->timestampVisitStart) {
            $query->andWhere(['<=', "timestamp_visit", $this->timeToUTC($this->timestampVisitEnd)]);
        }

        return $dataProvider;
   }

   /**
     * Convert string time in format $format to UTC time format for SQL where clause
     * @param string $time Time in format $format
     * @param string $format Format of $time for the function date, default 'Y-m-d H:i:s'
     */
    private function timeToUTC($time, $format='Y-m-d H:i:s')
    {
        $timezoneOffset = \Yii::$app->formatter->asDatetime('now', 'php:O');
        return date($format, strtotime($time.$timezoneOffset));
    }
}

显示您的$searchmodel我想问一下，您使用的“timestamp\u visit”属性来自数据库，它的列名为“timestamp\u visit”，对吗？还有数据库中的“timestampVisitStart”和“timestampVisitEnd”？或者您只是在searchModel中声明？是的，timestamp\u visit是MySQL类型timestamp的DB字段。timestampVisitStart和timestampVisitEnd当然只在搜索模型中声明。谢谢，但很抱歉再次询问行为函数中的类名是指哪个类？因为我现在很困惑。类名只是此行为中的一个声明用法，或者我需要将其更改为我的模型类名？DateRangeBehavior:：className返回DateRangeBehavior的完全限定类名，因此请像在我的示例中一样使用它。行为配置需要行为的类名才能将其添加到当前模型中。因为自Yii 2.0.14以来，className已被弃用，所以我将其更改为：：class。但它也适用于：：className。在我的示例中，您需要将timestamp\u visit和timestamp\u visit更改到目前为止。这就是你所需要的。我已经更改了你在我的搜索模型中告诉我的内容，但在我的GridView中，在我选择特定日期后，它仍然显示所有结果。我的searchModel函数有任何影响吗？->public function search$params{$query=Lme:：find->orderBy['date'=>SORT\u DESC]；//在此处添加应始终应用的条件$dataProvider=new ActiveDataProvider['query'=>query'=>SORT'=>false/['defaultOrder'=>date'=>SORT\u DESC]];
