1) Installation

A) Download and install DCSRatingBundle

To install DCSRatingBundle run the following command

bash $ php composer.phar require damianociarla/rating-bundle

B) Enable the bundle

Enable the required bundles in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
    	// ...
    	new DCS\RatingBundle\DCSRatingBundle(),
	);
}

2) Create your Vote and Rating classes

In this first release DCSRatingBundle supports only Doctrine ORM. However, you must provide a concrete Vote and Rating class. You must extend the abstract entities provided by the bundle and creating the appropriate mappings.

Rating

<?php
// src/MyProject/MyBundle/Entity/Rating.php

namespace MyProject\MyBundle\Entity;

use DCS\RatingBundle\Entity\Rating as BaseRating;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 */
class Rating extends BaseRating
{
    /**
     * @ORM\Id
     * @ORM\Column(type="string")
     */
    protected $id;

    /**
     * @ORM\OneToMany(targetEntity="MyProject\MyBundle\Entity\Vote", mappedBy="rating")
     */
    protected $votes;
}

Vote

<?php
// src/MyProject/MyBundle/Entity/Vote.php

namespace MyProject\MyBundle\Entity;

use DCS\RatingBundle\Entity\Vote as BaseVote;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\ChangeTrackingPolicy("DEFERRED_EXPLICIT")
 */
class Vote extends BaseVote
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToOne(targetEntity="MyProject\MyBundle\Entity\Rating", inversedBy="votes")
     * @ORM\JoinColumn(name="rating_id", referencedColumnName="id")
     */
    protected $rating;

    /**
     * @ORM\ManyToOne(targetEntity="MyProject\UserBundle\Entity\User")
     */
    protected $voter;
}

3) Configure your application

# app/config/config.yml

dcs_rating:
    db_driver: orm
    base_path_to_redirect: / # when the permalink is not configured
    max_value: 5 # maximum value for the vote (stars displayed)
    model:
        rating: MyProject\MyBundle\Entity\Rating
        vote: MyProject\MyBundle\Entity\Vote

4) Import DCSRatingBundle routing

Import the bundle routing:

dcs_rating:
    resource: "@DCSRatingBundle/Resources/config/routing.xml"
	prefix:   /

5) Import stylesheet in your template

To import the stylesheet run the following command:

bash $ php app/console assets:install

and include the stylesheet in your template:

<link rel="stylesheet" href="{{ asset('bundles/dcsrating/css/rating.css') }}" />

5.1) Enable vote via ajax

To vote via ajax you have to include the script below after loading the jQuery library:

<script src="{{ asset('bundles/dcsrating/js/rating.js') }}"></script>

6) Showing rating and enabling vote

You can only vote the page you are in. You can not vote a page while you are on a different one. But you can show the rating of a page (read-only mode) in any page

Showing rating

You can show rating using stars without enabling voting:

{% include 'DCSRatingBundle:Rating:rating.html.twig' with {'id' : 'YOUR_UNIQUE_ID'} %}

This is useful if you have a list of items and want to show the rating of each item.

Enabling vote

To enable voting on a page use the following twig code:

{% include 'DCSRatingBundle:Rating:control.html.twig' with {'id' : 'YOUR_UNIQUE_ID'} %}

If you need to change the default user role for a specific page, add the role parameter:

{% include 'DCSRatingBundle:Rating:control.html.twig' with {'id' : 'YOUR_UNIQUE_ID', 'role' : 'ROLE_USER'} %}

If you need to change the permalink, add the permalink parameter, otherwise it will be stored the current route:

{% include 'DCSRatingBundle:Rating:control.html.twig' with {'id' : 'YOUR_UNIQUE_ID', 'permalink' : url('YOUR_ROUTE_ID')} %}
