我试图通过ajax呈现listview,但它给了我以下错误:
Exception (Invalid Configuration) 'yiibaseInvalidConfigException' with message ' ;The "dataProvider" property must be set. 控制器: public function actionLoadListviewAjax() { $dataProvider = // call to a function which returns ArrayDataProvider return $this->renderAjax('myview',[ 'dataProvider' => $dataProvider ]); } 视图: echo ListView::widget([ 'dataProvider' => $dataProvider,'itemView' => 'items','options' => ['class' => 'list-view-post'],'summary' => '','emptyText' => '',]); $dataProvder: <pre>yiidataArrayDataProvider Object ( [key] => [allModels] => Array ( [0] => Array ( [RecommendationCategory] => [ID] => 37 [GUID] => [Title] => test [WallPostTypeID] => 1 [RecommendationCategoryID] => 0 [CommentsJSON] => [TotalComments] => [PostedMessage] => test [FirstName] => test [LastName] => test [ProfileImagePath] => Lighthouse.jpg [AddedOn] => 2015-07-18 15:14:06 [ImagePath] => [CommentProfileImagePath] => [IsSubscribe] => 1 ) ) [id] => [_sort:yiidataBaseDataProvider:private] => [_pagination:yiidataBaseDataProvider:private] => [_keys:yiidataBaseDataProvider:private] => [_models:yiidataBaseDataProvider:private] => [_totalCount:yiidataBaseDataProvider:private] => [_events:yiibaseComponent:private] => Array ( ) [_behaviors:yiibaseComponent:private] => ) 我也尝试了renderPartial,但仍然是同样的错误.任何想法为什么它给出了这个例外? 更新: 在我的itemView文件项中,我有另一个列表视图,它给出了异常. 解决方法
实际上,列表视图项不必访问已通过窗口小部件发送的外部变量.
但是,如果必须在内部视图文件中使用$dataProvider变量,请尝试使用callable在列表视图中显示项目. 这样的事情: “` echo ListView::widget([ 'dataProvider' => $dataProvider,'itemView' => function ($model,$key,$index,$widget) { return $this->renderAjax('items',[ 'dataProvider' => $widget->dataProvider,]); },]); “` 更多信息在这里 http://www.yiiframework.com/doc-2.0/yii-widgets-listview.html# $ItemView控件细节 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
