yii使用CSqlDataProvider獲取數據

Question

我嘗試使用CSQLDataProvider獲取值，但出現錯誤消息。 未定義指數：ID K：\警予，1.1.8.r3324 \框架\網絡\ CSqlDataProvider.php（116）

這裏是我的代碼

車型

class Product extends CActiveRecord{ 
... 
public function getProductsForIndexPage(){ 
     $sql = ' 
      SELECT P.* FROM Product P, Make M, Company C 
      WHERE M.makeId=P.makeId AND C.companyId= P.companyId 
     '; 
     return new CSqlDataProvider($sql); 
} 
} 

視圖

$model = new Product(); 
$this->widget('zii.widgets.grid.CGridView', array(
     'dataProvider'=>$model->getProductsForIndexPage(), 
     'columns'=>array(
       'name' 

     ), 
)); 

Answer 1

試試這個：

return new CSqlDataProvider($sql, array('keyField' => 'productId')); 

凡'productId' - 表Product

Answer 2

Try this 

In model 

public function reportSearch() 
    { 
     $query = "SELECT * FROM ("; 

     $countQuery = 'SELECT count(*) FROM ('; 

     $qryBody = " 
      SELECT p_id, name, sum(stock_qty) as stock_qty, sum(sales_qty) as sales_qty, (sum(stock_qty) - sum(sales_qty)) as stock_in_hand FROM 
      ( 
       SELECT p.id as p_id, p.name as name, 0 as stock_qty, 0 as sales_qty FROM jubal.product p where status != 'D' 
       UNION 
       SELECT ps.product_id as p_id, '-' as name, sum(ps.qty) as stock_qty, 0 as sales_qty FROM jubal.product_stock ps 
       ".($this->shortDate ? "where ps.purchase_date <= '".Product::dateFormat($this->shortDate)."'" : "")." group by ps.product_id 
       UNION 
       SELECT si.product_id as p_id, '-' as name, 0 as stock_qty, sum(si.quantity) as sales_qty FROM jubal.sales_bill si where status!= 'D' 
       ".($this->shortDate ? "AND si.sales_date <= '".Product::dateFormat($this->shortDate)."'" : "")." group by si.product_id 
      ) ss GROUP BY p_id 
      ) res"; 

     $query .= $qryBody; 
     /*print_r($query); 
     exit();*/ 
     $countQuery .= $qryBody; 

     $condition = ""; 
     if(!empty($this->id)){ 
      $condition .= "p_id like'%". $this->id. "%'"; 
     } 

     if(!empty($this->name)){ 
      $condition = (!empty($condition) ? $condition." and " : ''); 
      $condition .= "name like '%". $this->name. "%'"; 
     } 

     if(!empty($this->stock_qty)){ 
      $condition = (!empty($condition) ? $condition." and " : ''); 
      $condition .= "stock_qty = '". $this->stock_qty. "'"; 
     } 

     if(!empty($this->sales_qty)){ 
      $condition = (!empty($condition) ? $condition." and " : ''); 
      $condition .= "sales_qty = '". $this->sales_qty. "'"; 
     }

      $condition = (!empty($condition) ? $condition." and " : ''); 
      $condition .= "stock_in_hand = '". $this->stock_in_hand. "'"; 
     } 


     $query .= (!empty($condition) ? " where ". $condition : ''); 

     $countQuery .= (!empty($condition) ? " where ". $condition : ''); 


     /* print_r($query); 
     exit();*/ 
     /* print_r($countQuery); 
     exit();*/ 

     // SELECT p_id, name, sum(stock_qty) as stock_qty, sum(sales_qty) as sales_qty, (sum(stock_qty) - sum(sales_qty)) as stock_in_hand 

     $count=Yii::app()->db->createCommand($countQuery)->queryScalar(); 
     return new CSqlDataProvider($query, array(
      'totalItemCount'=>$count, 
      'keyField' => 'p_id', 
      'sort'=>array(
       'attributes'=>array(
        'p_id', 'name', 'stock_qty', 'sales_qty', 'stock_in_hand' 
       ), 
      ), 
      'pagination'=>array(
       'pageSize'=> Yii::app()->user->getState('pageSize', Yii::app()->params[ 'defaultPageSize' ]), 
      ), 
     )); 
    }
