修改 dataProvider 数组中 CFormModel 的值

Question

所以另一个问题...我必须格式化通过 CFormModel 设置的数字，但问题是，如果我 var_dump dataProvider，属性不会设置，但它们会出现在网站上。另外，如果我调用 $dataProvider->value （其中 value 作为 CFormModel 扩展类中的公共参数存在），Yii 表示该值未设置（证明 var_dump() 是正确的）

1. 怎么会？

2. 如何通过number_format()或Yii相关方法修改号码？

   CActiveDataProvider Object
   (
     [modelClass] => VouchersTransactions
     [model] => VouchersTransactions Object
     (
       [_new:CActiveRecord:private] => 
       [_attributes:CActiveRecord:private] => Array
           (
           )
   
       [_related:CActiveRecord:private] => Array
           (
           )
   
       [_c:CActiveRecord:private] => 
       [_pk:CActiveRecord:private] => 
       [_alias:CActiveRecord:private] => t
       [_errors:CModel:private] => Array
           (
           )
   
       [_validators:CModel:private] => 
       [_scenario:CModel:private] => 
       [_e:CComponent:private] => 
       [_m:CComponent:private] => 
   )
   
    [keyAttribute] => 
    [_criteria:CActiveDataProvider:private] => CDbCriteria Object
   (
       [select] => *
       [distinct] => 
       [condition] => user_id = 141
       [params] => Array
           (
           )
   
       [limit] => -1
       [offset] => -1
       [order] => 
       [group] => 
       [join] => 
       [having] => 
       [with] => 
       [alias] => 
       [together] => 
       [index] => 
       [scopes] => 
       [_e:CComponent:private] => 
       [_m:CComponent:private] => 
   )
   
   [_countCriteria:CActiveDataProvider:private] => 
   [_id:CDataProvider:private] => VouchersTransactions
   [_data:CDataProvider:private] => 
   [_keys:CDataProvider:private] => 
   [_totalItemCount:CDataProvider:private] => 
   [_sort:CDataProvider:private] => 
   [_pagination:CDataProvider:private] => 
   [_e:CComponent:private] => 
   [_m:CComponent:private] => 
   )
   

这是打印的dataProvider

      $dataProvider = new CActiveDataProvider('VouchersTransactions', array(
        'criteria' => array(
            'condition' => 'user_id = ' . Yii::app()->user->id,
        ),
      ));

这是 dataProvider，其中 VoucherTransactions 是不同模块内的模型

L.E.

    0 => VouchersTransactions#1
    (
      [CActiveRecord:_new] => false
      [CActiveRecord:_attributes] => array
    (
        'id' => '48'
        'user_id' => '141'
        'number_vouchers' => '1'
        'voucher_value' => '0.0100'
        'date_created' => '2014-07-11 10:06:22'
    )
    [CActiveRecord:_related] => array()
    [CActiveRecord:_c] => null
    [CActiveRecord:_pk] => '48'
    [CActiveRecord:_alias] => 't'
    [CModel:_errors] => array()
    [CModel:_validators] => null
    [CModel:_scenario] => 'update'
    [CComponent:_e] => null
    [CComponent:_m] => null
    )
    1 => VouchersTransactions#2
    (
      [CActiveRecord:_new] => false
      [CActiveRecord:_attributes] => array
    (
        'id' => '52'
        'user_id' => '141'
        'number_vouchers' => '1'
        'voucher_value' => '10.0000'
        'date_created' => '2014-07-11 10:15:06'
    )
    [CActiveRecord:_related] => array()
    [CActiveRecord:_c] => null
    [CActiveRecord:_pk] => '52'
    [CActiveRecord:_alias] => 't'
    [CModel:_errors] => array()
    [CModel:_validators] => null
    [CModel:_scenario] => 'update'
    [CComponent:_e] => null
    [CComponent:_m] => null
)

这就是我转储 $dataProvider->data 时得到的结果，但我无法更改那里的信息

Answer 1

所以我使用模型中的 Yii afterSearch() 方法解决了这个问题。当您必须修改这样的值时使用的好方法。

  public function afterSave() {
      //do modification here
      return parent::afterSave();
  }
