PropelEventBundle

Propel events in Symfony2.

Using with Symfony2 2.1

To use this bundle with version 2.1 you have to override parameter dispatcher.class with:

<parameter key="glorpen.propel.event.dispatcher.class">Symfony\Component\EventDispatcher\ContainerAwareEventDispatcher</parameter>

How to install

• add this plugin to your project. From your project root:

  hg clone https://bitbucket.org/glorpen/glorpenpropeleventbundle Glorpen/PropelEvent

• enable the plugin in your AppKernel class

app/AppKernel.php

<?php

class AppKernel extends AppKernel
{
   public function registerBundles()
   {
       $bundles = array(
           ...
           new Glorpen\PropelEvent\PropelEventBundle\PropelEventBundle(),
           ...
       );
   }
}

• add behavior to propel config (only if you want use events on propel post/pre hooks)

or you can import PropelEventBundle/Resources/config/propel_config.yml for class definition

propel:
   build_properties:
     propel.behavior.event.class: 'src.Glorpen.PropelEvent.PropelEventBundle.behavior.EventBehavior'
     propel.behavior.default: "event"

Listening for propel hooks

• register listener

<service class="SomeBundle\Listeners\HistoryBehaviorListener">
        <argument type="service" id="security.context" />
        <tag name="propel.event" />
</service>

<service id="my.listener" class="SomeBundle\Listeners\HistoryBehaviorListener">
        <tag name="propel.event" method="onPropelEventSave" event="model.save.post" />
</service>

Custom events

You can trigger events with generic or custom Event class, in following example ValidationEvent.

• create ValidationEvent event

<?php

namespace YourBundle\Events;
use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\EventDispatcher\Event;

class ValidationEvent extends Event {
   private $metadata;

   public function __construct(ClassMetadata $metadata){
      $this->metadata = $metadata;
   }

   /**
    * @return \Symfony\Component\Validator\Mapping\ClassMetadata
    */
   public function getMetadata(){
      return $this->metadata;
   }
}

• register listener in services.xml

<service id="your.service" class="%your.service.class%">
   <argument>%your.service.argument%</argument>
   <tag name="propel.event" method="onProductLoadValidatorMetadata" event="product.validation" />
</service>

• and then use it within model class

<?php

namespace YourBundle\Model;
use YourBundle\Events\ValidationEvent;
use Glorpen\PropelEvent\PropelEventBundle\Dispatcher\EventDispatcherProxy;
use Symfony\Component\Validator\Mapping\ClassMetadata;
use YourBundle\Model\om\BaseProduct;

class Product extends BaseProduct {
   public static function loadValidatorMetadata(ClassMetadata $metadata)
   {
      EventDispatcherProxy::trigger('product.validation', new ValidationEvent($metadata));
   }
}
