Validation rules and mass assignment
------------------------------------
In Yii2 unlike Yii 1.x validation rules are separated from mass assignment. Validation
rules are described in `rules()` method of the model while what's safe for mass
assignment is described in `scenarios` method:
```php
function rules() {
return array(
// rule applied when corresponding field is "safe"
array('username', 'length', 'min' => 2),
array('first_name', 'length', 'min' => 2),
array('password', 'required'),
// rule applied when scenario is "signup" no matter if field is "safe" or not
array('hashcode', 'check', 'on' => 'signup'),
);
}
function scenarios() {
return array(
// on signup allow mass assignment of username
'signup' => array('username', 'password'),
'update' => array('username', 'first_name'),
);
}
```
Note that everything is unsafe by default and you can't make field "safe"
without specifying scenario.
