在更新时，跳过更新yii中的某些属性

i need to stop updating certain value even those are set to POST array. to do that i am using unsafe in yii rules.

我需要停止更新某些值，即使它们被设置为POST数组。为此，我在yii规则中使用了不安全。

array('id', 'unsafe', 'on'=>'update'),

still with this, i am unable to skip the id from updating.

尽管如此，我还是无法跳过更新id。

how can this be done with yii?

如何用yii实现这一点?

below is my rules function..

下面是我的规则函数。

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('name, body, created_date', 'required'),
        array('name', 'length', 'max'=>128),
        array('body', 'length', 'max'=>512),
        array('id', 'unsafe', 'on'=>'update'),
        // The following rule is used by search().
        // @todo Please remove those attributes that should not be searched.
        array('id, name, body, created_date', 'safe', 'on'=>'search'),
    );
}

When you are creating the new model instance in your controller you will need to declare the scenario for example if your declaration was something like this

当您在控制器中创建新的模型实例时，您将需要声明场景，例如，如果您的声明是这样的

$myModelInstance = new MyModel();

you will need to change it to

您需要将其更改为

$myModelInstance = new MyModel('update');

However if you are using one of the find methods of active records to save it then it is set automatically to "update" as here: http://www.yiiframework.com/doc/api/1.1/CActiveRecord#save-detail

但是，如果您正在使用活动记录的一个查找方法来保存它，那么它将自动设置为“更新”:http://www.yiiframework.com/doc/api/1.1/CActiveRecord#save-detail。

if you are using some other logic for declaring the model you can simply use the setScenario function

如果您正在使用其他逻辑来声明模型，您可以使用setScenario函数

$myModel->setScenario("update");
