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.
