Type Multiple Files Upload.

Usage example inside your {{luya\admin\ngrest\base\NgRestModel::ngRestAttributeTypes}} method:

return [
    'myfiles' => 'fileArray',
];

If you like to get the {{luya\admin\file\Iterator}} object directly from the {{luya\admin\storage\BaseFileSystemStorage}} component just enable $fileIterator.

return [
    'myfiles' => ['fileArray', 'fileIterator' => true],
];

Now when accessing the $myfiles variabled defined from above the {{luya\admin\file\Iterator}} will be returned ottherwise false.

__call() public method

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

Calls the named method which is not a class method.

This method will check if any attached behavior has the named method and will execute it if available.

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.

public mixed __call ( $name, $params )
$name string

The method name

$params array

Method parameters

return mixed

The method return value

throws yii\base\UnknownMethodException

when calling unknown method

{
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $object) {
        if ($object->hasMethod($name)) {
            return call_user_func_array([$object, $name], $params);
        }
    }
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}

            
__clone() public method

Defined in: yii\base\Component::__clone()

This method is called after the object is created by cloning an existing one.

It removes all behaviors because they are attached to the old object.

public void __clone ( )

                public function __clone()
{
    $this->_events = [];
    $this->_eventWildcards = [];
    $this->_behaviors = null;
}

            
__construct() public method

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

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

            
__get() public method

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

Returns the value of a component property.

This method will check in the following order and act accordingly:

  • a property defined by a getter: return the getter result
  • a property of a behavior: return the behavior property value

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

See also __set().

{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        // read property, e.g. getName()
        return $this->$getter();
    }
    // behavior property
    $this->ensureBehaviors();
    foreach ($this->_behaviors as $behavior) {
        if ($behavior->canGetProperty($name)) {

This method will check in the following order and act accordingly:

  • a property defined by a setter: return whether the property is set
  • a property of a behavior: return whether the property is set
  • return false for non existing properties

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($component->property).

See also https://www.php.net/manual/en/function.isset.php.

As the angular attributes have different names in different contexts, this will append the correct context.

$this->appendFieldNgModelContext('myfieldname', self::LIST_CONTEXT_PREFIX);
protected string appendFieldNgModelContext ( $field, $context )
$field string
$context string

                protected function appendFieldNgModelContext($field, $context)

}

            
attachBehavior() public method

Defined in: yii\base\Component::attachBehavior()

Attaches a behavior to this component.

This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.

See also detachBehavior().

public yii\base\Behavior attachBehavior ( $name, $behavior )
$name string

The name of the behavior.

$behavior string|array|yii\base\Behavior

The behavior configuration. This can be one of the following:

return yii\base\Behavior

The behavior object

                public function attachBehavior($name, $behavior)
{
    $this->ensureBehaviors();
    return $this->attachBehaviorInternal($name, $behavior);
}

            
attachBehaviors() public method

Defined in: yii\base\Component::attachBehaviors()

Attaches a list of behaviors to the component.

Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.

See also attachBehavior().

public void attachBehaviors ( $behaviors )
$behaviors array

List of behaviors to be attached to the component

                public function attachBehaviors($behaviors)
{
    $this->ensureBehaviors();
    foreach ($behaviors as $name => $behavior) {
        $this->attachBehaviorInternal($name, $behavior);
    }
}

            
behaviors() public method

Defined in: yii\base\Component::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

public array behaviors ( )
return array

The behavior configurations.

                public function behaviors()
{
    return [];
}

            
canGetProperty() public method

Defined in: yii\base\Component::canGetProperty()

Example Response

return [

];

The above service data can be used when creating the tags with $this->getServiceName('titles').

public boolean|array serviceData ( $event )
$event yii\base\Event

                public function serviceData($event)
{
    return false;
}

            
setSortField() public method (available since version 2.0.0)
public void setSortField ( $field )
$field string|array

A sort field definition, this can be either a string firstname or an array with a definition or multiple definitions

'sortField' => [
    'asc' => ['fist_name' => SORT_ASC, 'last_name' => SORT_ASC],
    'desc' => ['first_name' => SORT_DESC, 'last_name' => SORT_DESC],
]

Or you have an ngrest attribute which does not exists in the database, so you can define the original sorting attribute:

'sortField' => 'field_name_inside_the_table'

which is equals to

'sortField' => [
   'asc' => ['field_name_inside_the_table' => SORT_ASC],
   'desc' => ['field_name_inside_the_table' => SORT_DESC],
]

A very common scenario when define sortField is when display a value from a relation, therefore you need to prepare the data provider inside the API in order to join the relation (joinWith(['relationName])) aftewards you can use the table name

'sortField' => [
     'asc' => ['city_table.name' => SORT_ASC],
     'desc' => ['city_table.name' => SORT_DESC],
]

There are situations you might turn of the sorting for the given attribute therefore just sortfield to false:

'sortField' => false,

In order to enable order by counting of relation tables update the APIs {{luya\admin\ngrest\base\Api::prepareListQuery()}} with the given sub select condition where the alias name is equal to the field to sort:

public function prepareListQuery()
{
    return parent::prepareListQuery()->select(['*', '(SELECT count(*) FROM admin_tag_relation WHERE tag_id = id) as relationsCount']);
}

Where in the above example relationsCount would be the sortField name.

                public function setSortField($field)
{
    $this->_sortField = $field;
}

            
trigger() public method

                public function trigger($name, Event $event = null)
{
    $this->ensureBehaviors();
    $eventHandlers = [];
    foreach ($this->_eventWildcards as $wildcard => $handlers) {
        if (StringHelper::matchWildcard($wildcard, $name)) {
            $eventHandlers[] = $handlers;
        }
    }
    if (!empty($this->_events[$name])) {
        $eventHandlers[] = $this->_events[$name];
    }
    if (!empty($eventHandlers)) {
        $eventHandlers = call_user_func_array('array_merge', $eventHandlers);
        if ($event === null) {
            $event = new Event();
        }
        if ($event->sender === null) {
            $event->sender = $this;
        }
        $event->handled = false;
        $event->name = $name;
        foreach ($eventHandlers as $handler) {
            $event->data = $handler[1];
            call_user_func($handler[0], $event);
            // stop further handling if the event is handled
            if ($event->handled) {
                return;
            }
        }
