Php 致命错误：对非对象调用成员函数getDbCriteria（）

我使用的是Yii 1.1.15，出现了这个错误

致命错误：对非对象调用成员函数getDbCriteria（）

我认为下面的代码是正确的

  <?php
                        $model = new Comment(); //name of my model Project refers to Mysql innoDB table tblproject.
                        $daten=$model::model();
                        $dataProvider=new CActiveDataProvider($daten->with(array('posts' => array('limit'=>6)))->findAll());

                        $this->widget('zii.widgets.CListView', array(
                            'dataProvider'=>$dataProvider,
                            'itemView'=>'_view_latest_comment', //view file location
                        ));
                   ?>

更新： 我也尝试过这个，但它没有将限制设置为5

$model = new Comment(); 
$daten=$model::model();
                    $criteria = new CDbCriteria;
                    $criteria->limit=5;

$dataProvider=new CActiveDataProvider($daten, array('criteria'=>$criteria));

当i

print\r（$daten）时我明白了

我正在尝试动态设置返回结果的限制，但似乎无法使其正常工作。知道我做错了什么或错过了什么吗？感谢
数据提供程序要求第一个参数为类名或模型实例。在您看来，这是
findAll（）
的结果

将带有

子句的

移动到第二个参数，如下所示：

<?php
$dataProvider = new CActiveDataProvider(Comment::model(), array(
    'criteria' => array(
        'with' => array('posts')
)));

$this->widget('zii.widgets.CListView', array(
    'dataProvider' => $dataProvider,
    'itemView' => '_view_latest_comment', //view file location
));

这可能会帮助你@KirenSiva尝试过它。它没有设置限制，但这次没有错误。更新了问题TooGetDbCriteria函数从何处调用？@PeterM页面刚刚死亡，它显示了以下
致命错误：调用成员函数getDbCriteria（）在第225行的/Applications/XAMPP/xamppfiles/htdocs/dev/common/lib/yii/framework/web/cactivedaptrovider.php中的非对象上
@PratipGhosh我没有调用getDbCriteria的代码。当我搜索我的项目时，唯一找到的
getDbCriteria
位于
dev/common/lib/yii/framework/db/ar/CActiveFinder.php
中，它仍然没有限制输出。是因为self：：有很多关系吗<代码>$dataProvider=新的CActiveDataProvider（Comment:：model（），数组（'criteria'=>array（'with'=>array（'posts'=>array（'limit'=>2））））这完全是另一回事，我建议如果你在限制方面还有问题，可以问新问题。也许您必须在
标准中设置限制
数组？通常，dataprovider会自行设置其限制/偏移量，因此dataprovider可能会对此进行验证。
<?php
$dataProvider = new CActiveDataProvider(Comment::model(), array(
    'criteria' => array(
        'with' => array('posts')
)));

$this->widget('zii.widgets.CListView', array(
    'dataProvider' => $dataProvider,
    'itemView' => '_view_latest_comment', //view file location
));

$dataProvider=new CActiveDataProvider('Post', array(
     'criteria'=>array(
          'condition'=>'status=1',
          'order'=>'create_time DESC',
          'with'=>array('author'),
     ),
     'countCriteria'=>array(
          'condition'=>'status=1',
          // 'order' and 'with' clauses have no meaning for the count query
     ),
     'pagination'=>array(
          'pageSize'=>20,
     ),
));
