The Navbar Tasks Component

Routes

Just like the other theme components, this one requires some route aliases to work. Please refer to the component overview to learn about the route alias details.

Required aliases

• all_task
• task

Data Model

In order to use this component, your user class has to implement the Avanzu\AdminThemeBundle\Model\TaskInterface

<?php
namespace MyAdminBundle\Model;
// ...
use Avanzu\AdminThemeBundle\Model\TaskInterface as ThemeTask

class TaskModel implements  ThemeTask {
	// ...
	// implement interface methods
	// ...
}

Event Listener

Next, you will need to create an EventListener to work with the TaskListEvent.

<?php
namespace MyAdminBundle\EventListener;

// ...

use Avanzu\AdminThemeBundle\Event\TaskListEvent;
use MyAdminBundle\Model\TaskModel;

class MyTaskListListener {

	// ...

	public function onListTasks(TaskListEvent $event) {

		foreach($this->getTasks() as $task) {
			$event->addTask($task);
		}

	}

	protected function getTasks() {
		// retrieve your task models/entities here
	}

}

Service.xml

Finally, you need to attach your new listener to the event system:

<!-- Resources/config/services.xml -->
<parameters>
	<!-- ... -->
	<parameter key="my_admin_bundle.task_list_listener.class">MyAdminBundle\EventListener\MyTaskListListener</parameter>
	<!-- ... -->
</parameters>
<services>
	<!-- ... -->
	<service id="my_admin_bundle.task_list_listener" class="%my_admin_bundle.task_list_listener.class%">
        <tag name="kernel.event_listener" event="theme.tasks" method="onListTasks" />
    </service>
	
	<!-- ... -->
</services>
