Model Push for the CakePHP Ratchet plugin.

What is Ratchet

Ratchet for CakePHP brings the Ratchet websocket server to CakePHP. Websockets allow you to utilize near-real-time communication between your application and it's visitors. For example notifying a page the associated record in the database has been updated using the Pushable behaviour.

Getting started

1. Requirements

This plugin depends on the following plugins and their dependencies and are pulled in by composer later on:

2. Composer

Make sure you have composer installed and configured with the autoloader registering during bootstrap as described here. Make sure you have a composer.json and add the following to your required section.

composer require wyrihaximus/ratchet-model-push 

When you've set everything up, run composer install.

3. Setup the plugin

Make sure you load RatchetModelPush and all the plugins it depends on and their dependecies in your bootstrap and set then up properly.

4. Setting up the behavior

The following code example attaches the Pushable behavior to the WyriProject model. The events do the following in order:

  1. Fires on creating on a new record and binds to WyriProject.created.
  2. Fires on updating any record and binds to WyriProject.updated.
  3. Fires on any updating record and binds to WyriProject.updated.{id} where {id} is the id for that record. So if id is 1 it binds to WyriProject.updated.1.

The data is passed into the event as a 1 dimensional array.

<?php

class Model extends AppModel {
    public $actsAs = array(
        'RatchetModelPush.Pushable' => array(
            'events' => array(
                array(
                    'eventName' => 'WyriProject.created',
                    'created' => true,
                ),
                array(
                    'eventName' => 'WyriProject.updated',
                    'created' => false,
                ),
                array(
                    'eventName' => 'WyriProject.updated.{id}',
                    'created' => false,
                    'fields' => true,
                ),
            ),
        ), 
    );
}

5. Client side

On the client side the only thing required is subscribing to the event:

cakeWamp.subscribe('Rachet.WampServer.ModelUpdate.WyriProject.updated.1', function(topicUri, event) {
	// Do your stuff with the data
});

Note: the actual event you're subscribing to is prefixed by Rachet.WampServer.ModelUpdate..

Make sure to include the JavaScript file and its dependencies in your view:

echo $this->Html->script(array(
    'Ratchet.when/when',
    'Ratchet.autobahn/autobahn',
    'Ratchet.cake-wamp'
));
