README

A redis driven like engine.

Installation

Install through composer:

php -d memory_limit=-1 composer.phar require xlabs/likebundle

This bundle depends on "xlabs/rabbitmqbundle". Make sure to set it up too.

In your AppKernel

public function registerbundles()
{
    return [
    	...
    	...
    	new XLabs\LikeBundle\XLabsSocialBundle(),
    ];
}

php bin/console doctrine:schema:update --force

Routing

Append to main routing file:

# app/config/routing.yml
  
xlabs_like_engine:
    resource: "@XLabsLikeBundle/Resources/config/routing.yml"
    #prefix:   /

Configuration sample

Default values are shown below:

# app/config/config.yml
  
x_labs_like:
    redis_settings:
        host: 192.168.5.23
        port: 6379
        db_id: 7
    _key_namespace: 'xlabs:like'
    _star_key_namespace: 'xlabs:star'
    backup: # for mysql backup/restore
        <alias>: <entity_FQCN>
    star_rating:
        amount: 5 # amount of stars, 5 is the default

assetic:
    ...
    bundles: [ ..., 'XLabsLikeBundle']
    ...

Usage

Append this anywhere in you template

{% include 'XLabsLikeBundle:Like:loader.html.twig' %}

To see a sample template, check:

XLabsLikeBundle:Like:example.html.twig

MySQL Backup

Make sure you run the following command. This is the consumer that will save all operations in the project DB.

php bin/console xlabs:like:mysql_backup --no-debug

If ever Redis lost all the data, you will be able to recover it by issueing the following command:

php bin/console xlabs:like:restore --no-debug

If you already have data in redis and want to create a mysql backup of it, there´s a sample one-time command you should copy to your project and adapt conveniently:

php bin/console xlabs:like:initial_backup --no-debug

Event listener

If you want some action to take place whenever a LIKE takes place in the frontends, you can create an event listener as follows:

# YourBundle/Resources/config/services.yml
    ...
    xlabs_like.event_listener:
        class:  YourBundle\EventListeners\YourListener.php
        tags:
            - { name: kernel.event_listener, event: xlabs_like.event, method: yourListenerMethod }

use Symfony\Component\EventDispatcher\Event;
  
class YourListener extends Event
{
    public function yourListenerMethod(Event $event)
    {
        dump($event->getLike()); die;
    }
}

The $event variable contains all info about the LIKE action that has taken place.

Tweaking

By default, the service uses the user in session. If you ever wanted to use the service on your own by using any specific user performing the LIKE action:

$user = $em->getRepository('YourBundle:YourUserEntity')->find(<ID>);
$like_engine = $container->get('xlabs_like_engine');
$like_engine->setUser($user);
$like_engine->...
