I have added a public property to my active record model class that doesn't map to a real table column but i have that property/attribute in a form and i want to validate it with the current model. I have tried to add a validation rule to that public property but nothing happens on it. How can i achieve this?

When you add a public attribute to an AR, (at least in Yii 1.0) you must have to set the attribute in the controller like this:

if(isset($_POST['yourModel']) {
$model->attributes = $_POST['yourModel'];
$model->newAttribute = $_POST['yourModel']['newAttribute'];
...
}
May be this was your problem, without this you never set the attribute value.

How about showing the snippets of what you tried.

php:
foreach(array('cat', 'dog', 'cow') as $animal) echo $animal."\n";

python:
[(animal, print(animal)) for animal in ['cat', 'dog', 'cow']]

ruby:
['cat', 'dog', 'cow'].each {|animal| puts animal}

You say Tomato, I say Tomato.

add it to your rule as safe to be able to set it via $model->attributes =$_POST['yourModel'];

public $newAttribute=int; // or whatever type

public function rules() 
{
...
array('newAttribute','safe'),
}

this must work, afterwards you should also be able to set a specific rule for your type to have validation.

you can also add something like this for customized validation of your attribute

protected function beforeValidate()
{
          
                if(!($this->newAttribute))
                {
                    $error=Yii::t('yourmodel','You must fill newAttribute');
                    $this->addError('newAttribute',$error);
                }
           
        return parent::beforeValidate();
}

Yes, please do because what you describe should be working. Have a look at the LoginForm generated by `yiic webapp`, which does the same and works fine.
