分析控制器中的$ _Post數據並渲染Cgridview時出現錯誤

Question

我正面臨着將正確的值傳遞給視圖中的網格小部件的問題。數據正在使用Ajax從jquery傳遞。

下面是代碼::

$('#find-product').click(function(e) { 
    e.preventDefault(); 


    alert($('#find-product').data("url")); 


    /* 
    * Make the ajax call to send the selected option to the controller for processing 
    * URL : $('#find-product').data("url") , the path of the controller's action 
    * Dropdown : the obejct that is passed to the controller 
    * 
    * Dropdown.category : the category selected 
    * Dropdown.price : the price range selected 
    * 
    * 
    */ 

    $.ajax({ 
     url: $('#find-product').data("url"), 
     data: { 
      Dropdown: { 
       category: $('#supp-category').find(":selected").text(), 
       price: $('#supp-price').find(":selected").text() 
      } 

     }, 
     type: "POST", 
     error: function(xhr, tStatus, e) { 
      if (!xhr) { 
       alert(" We have an error "); 
       alert(tStatus + " " + e.message); 
      } else { 
       alert("else: " + e.message); // the great unknown 
      } 
     }, 
     success: function(resp) { 
      document.location.href = $('#find-product').data("url"); 
     } 

    }) 
}); 

所以我想送命名下拉到控制器操作的對象。在這種情況下，它的/ products/dropdown。

在actionDropdown（）我試圖形成一個CDbCriteria並將其傳遞給CActiveDataProvider，以便我可以使用它來呈現網格。

下面是actionDropdown中的ProductsController代碼::

public function actionDropdown() { 


    $criteria = new CDbCriteria; 
    $criteria->compare('category', $_POST['Dropdown']['category'], true); 

    $dataProvider = new CActiveDataProvider('Products', array(
      'criteria' => $criteria, 

    )); 


    $this->render('selectproducts', array(
     'dataProvider' => $dataProvider, 
    )); 



} 

這裏是視圖，稱爲selectproducts。

<div class="row"> 


     <?php 
     $this->widget('bootstrap.widgets.TbGridView', array(
      'id' => 'products-grid', 
      'dataProvider' => $dataProvider, 

      'filter' => $dataProvider, 
      'columns' => array(
       'id', 
       'name', 
       'category', 
       'brand', 
       'weight_unit', 
       'price_unit', 
       'flavors', 
       'providers', 
      ), 
     )); 
     ?> 

    </div> 

現在，這給了我一個CException錯誤。這是錯誤堆棧跟蹤::

我不能爲我的生活弄清楚是什麼導致這個錯誤。請提供任何形式的幫助，任何會使我朝正確方向發展的提示。

謝謝，提前。 Maxx

問題是filter參數在TbGridView。過濾器必須是您的模型的實例，而不是數據提供者。

$this->widget('bootstrap.widgets.TbGridView', array(
    'id' => 'products-grid', 
    'dataProvider' => $dataProvider, 

    'filter' => $dataProvider->model, // Simplest way 
    'columns' => array(
     'id', 
     'name', 
     'category', 
     'brand', 
     'weight_unit', 
     'price_unit', 
     'flavors', 
     'providers', 
    ), 
)); 

或者只分配YourModel::model()作爲過濾器PARAM。
