On update, skip certain attributes from updating yii
model, php, yii
Solution
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
$myModelInstance = new MyModel();
you will need to change it to
$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
if you are using some other logic for declaring the model you can simply use the setScenario function
$myModel->setScenario("update");
Problem
i need to stop updating certain value even those are set to POST array. to do that i am using unsafe in yii rules. ``` array('id', 'unsafe', 'on'=>'update'), ``` still with this, i am unable to skip the id from updating. how can this be done with yii? below is my rules function.. ``` 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'), ); } ``` Update 1 $model->attributes = $_POST['User']; and i need when saving, to skip certain attributes. $model->save();
