BlameableBehavior, yii\behaviors\BlameableBehavior | API Documentation for Yii 2.0

Class yii\behaviors\BlameableBehavior

BlameableBehavior automatically fills the specified attributes with the current user ID.

To use BlameableBehavior, insert the following code to your ActiveRecord class:

use yii\behaviors\BlameableBehavior;

public function behaviors()
{
    return [
        BlameableBehavior::class,
    ];
}

By default, BlameableBehavior will fill the created_by and updated_by attributes with the current user ID when the associated AR object is being inserted; it will fill the updated_by attribute with the current user ID when the AR object is being updated.

Because attribute values will be set automatically by this behavior, they are usually not user input and should therefore not be validated, i.e. created_by and updated_by should not appear in the rules() method of the model.

If your attribute names are different, you may configure the $createdByAttribute and $updatedByAttribute properties like the following:

public function behaviors()
{
    return [
        [
            'class' => BlameableBehavior::class,
            'createdByAttribute' => 'author_id',
            'updatedByAttribute' => 'updater_id',
        ],
    ];
}

Property Details

Hide inherited properties

The attribute that will receive current user ID value Set this property to false if you do not want to record the creator ID.

Default value for cases when the user is guest

The attribute that will receive current user ID value Set this property to false if you do not want to record the updater ID.

In case, when the property is null, the value of Yii::$app->user->id will be used as the value.

The value that will be assigned to the current attributes. This can be an anonymous function, callable in array format (e.g. [$this, 'methodName']), an Expression object representing a DB expression (e.g. new Expression('NOW()')), scalar, string or an arbitrary value. If the former, the return value of the function will be assigned to the attributes. The signature of the function should be as follows,

function ($event)
{
    
}

Method Details

Hide inherited methods

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

Source code

                public function __call($name, $params)
{
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

Initializes the object with the given configuration $config.
Call init().

If this method is overridden in a child class, it is recommended that

the last parameter of the constructor is a configuration array, like $config here.
call the parent implementation at the end of the constructor.

public void __construct ( $config = [] ) $config array

Name-value pairs that will be used to initialize the object properties

Source code

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}

Defined in: yii\base\BaseObject::__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

See also canGetProperty().

public boolean canSetProperty ( $name, $checkVars = true ) $name string

The property name

$checkVars boolean

Whether to treat member variables as properties

return boolean

Whether the property can be written

Source code

                public function canSetProperty($name, $checkVars = true)
{
    return method_exists($this, 'set' . $name) || $checkVars && property_exists($this, $name);
}

Deprecated since 2.0.14. On PHP >=5.5, use ::class instead.

Source code

                public static function className()
{
    return get_called_class();
}

Defined in: yii\base\Behavior::detach()

Detaches the behavior object from the component.

The default implementation will unset the $owner property and detach event handlers declared in events(). Make sure you call the parent implementation if you override this method.

Source code

                public function detach()
{
    if ($this->owner) {
        foreach ($this->_attachedEvents as $event => $handler) {
            $this->owner->off($event, is_string($handler) ? [$this, $handler] : $handler);
        }
        $this->_attachedEvents = [];
        $this->owner = null;
    }
}

Source code

                public function evaluateAttributes($event)
{
    if (
        $this->skipUpdateOnClean
        && $event->name == ActiveRecord::EVENT_BEFORE_UPDATE
        && empty($this->owner->dirtyAttributes)
    ) {
        return;
    }
    if (!empty($this->attributes[$event->name])) {
        $attributes = (array) $this->attributes[$event->name];
        $value = $this->getValue($event);
        foreach ($attributes as $attribute) {
            
            if (is_string($attribute)) {
                if ($this->preserveNonEmptyValues && !empty($this->owner->$attribute)) {
                    continue;
                }
                $this->owner->$attribute = $value;
            }
        }
    }
}

Defined in: yii\behaviors\AttributeBehavior::events()

Declares event handlers for the $owner's events.

Child classes may override this method to declare what PHP callbacks should be attached to the events of the $owner component.

The callbacks will be attached to the $owner's events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.

The callbacks can be any of the following:

method in this behavior: 'handleClick', equivalent to [$this, 'handleClick']
object method: [$object, 'handleClick']
static method: ['Page', 'handleClick']
anonymous function: function ($event) { ... }

The following is an example:

[
    Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
    Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]

public array events ( ) return array

Events (array keys) and the corresponding event handler methods (array values).

Source code

                public function events()
{
    return array_fill_keys(
        array_keys($this->attributes),
        'evaluateAttributes'
    );
}

Get default value

Source code

                protected function getDefaultValue($event)
{
    if ($this->defaultValue instanceof \Closure || (is_array($this->defaultValue) && is_callable($this->defaultValue))) {
        return call_user_func($this->defaultValue, $event);
    }
    return $this->defaultValue;
}

Returns the value for the current attributes.

In case, when the $value property is null, the value of $defaultValue will be used as the value.

This method is called by evaluateAttributes(). Its return value will be assigned to the attributes corresponding to the triggering event.

protected mixed getValue ( $event ) $event yii\base\Event

The event that triggers the current attribute updating.

return mixed

The attribute value

Source code

                protected function getValue($event)
{
    if ($this->value === null && Yii::$app->has('user')) {
        $userId = Yii::$app->get('user')->id;
        if ($userId === null) {
            return $this->getDefaultValue($event);
        }
        return $userId;
    } elseif ($this->value === null) {
        return $this->getDefaultValue($event);
    }
    return parent::getValue($event);
}

Defined in: yii\base\BaseObject::hasMethod()

Returns a value indicating whether a method is defined.

The default implementation is a call to php function method_exists(). You may override this method when you implemented the php magic method __call().

Source code

                public function hasMethod($name)
{
    return method_exists($this, $name);
}

Defined in: yii\base\BaseObject::hasProperty()

Returns a value indicating whether a property is defined.

A property is defined if:

the class has a getter or setter method associated with the specified name (in this case, property name is case-insensitive);
the class has a member variable with the specified name (when $checkVars is true);
