different rules for the same AR model in Yii

Question

I have one model extending AR class with specific rules. But now i need to insert row into this table, but with other rules. Is i need to create other model with new rules, or it is possible to define orther rules?

Answer 1

You can set validation scenario. For example:

$model = new Post(); 
$model->scenario = 'new_line';
$model->attributes = $_GET['data'];
if ($model->validate()){
    $model->save(false);
}

in your model:

public function rules()
{
    return array(
        array('username, text', 'required','on' => 'new_line')
    );
}

In model rules all array lines must have key "on", else this rules will not apply.

If you are extending your class (active records) then you can actually just override your rules() function i.e.:

class User extends ActiveRecord(){
    function rules(){
        return array(array(
            // Nomrally a rule
        ))
    }
}

And then make your next class:

class User_extended extends ActiveRecord(){
    function rules(){
        return array(array(
            // Nomrally a rule
        ))
    }
}

And that should be it. You can then call the User_extended class and your rules will apply to the parent User class since Yii grabs the rules in a $this context and $this will be your child class.

But you can also use scenarios here, but it might get dirty especially if you need to override other methods.

thx. Now i'm trying to use this

/**
 * @param string $attribute fields names wich should be validated
 * @param array $params additional params for validation
 */
public function ValidatorName($attribute,$params) { … }
