Class yii\validators\SafeValidator

Inheritance	yii\validators\SafeValidator » yii\validators\Validator » yii\base\Component » yii\base\Object
Implements	yii\base\Configurable
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/validators/SafeValidator.php

SafeValidator serves as a dummy validator whose main purpose is to mark the attributes to be safe for massive assignment.

This class is required because of the way in which Yii determines whether a property is safe for massive assignment, that is, when a user submits form data to be loaded into a model directly from the POST data, is it ok for a property to be copied. In many cases, this is required but because sometimes properties are internal and you do not want the POST data to be able to override these internal values (especially things like database row ids), Yii assumes all values are unsafe for massive assignment unless a validation rule exists for the property, which in most cases it will. Sometimes, however, an item is safe for massive assigment but does not have a validation rule associated with it - for instance, due to no validation being performed, in which case, you use this class as a validation rule for that property. Although it has no functionality, it allows Yii to determine that the property is safe to copy.

Note: $when property is not supported by SafeValidator.
