屬性「CGridView.data」沒有定義

Question

我使用Yii框架，我想的東西添加到我的數據庫，我得到這個錯誤：

  CException 

Property "CGridView.data" is not defined.

我不知道哪裏出了問題究竟。我的數據庫中有4個其他表，這是唯一一個不能工作的表，並且出現錯誤。 你可以向我解釋出什麼問題嗎？是從我的數據庫中的問題??

後來它將記錄添加到數據庫中，即使它之前發生錯誤。

CGridView按照表格顯示數據項目列表。

由於CGidView沒有屬性「數據」而異常。類有屬性'dataProvider'。這是一個CGridView的簡單例子。您可以使用GII從您的模型生成示例。

// in your view. 
$this->widget('zii.widgets.grid.CGridView', array(
    'id' => 'document', 
    // you can't use key 'data' here 
    'dataProvider' => $document->search(), // @var Document $document - your model 
    'columns' => array(
     'id', 
     // ... other properties 
    ) 
)); 

// in model Document 
public function search() 
{ 
    $criteria = new CDbCriteria(); 

    $criteria->compare('id',$this->id); 
    //$criteria->compare('one_more_poperty', $this->one_more_poperty); 
    ... 

    return new CActiveDataProvider($this, array(
     'criteria'=>$criteria, 
    )); 
}
