Provides a trait to allow rating of any Eloquent models within your app for Laravel 5.

Ratings could be fivestar style, or simple +1/-1 style.

Installation

Require the package using Composer:

composer require willvincent/laravel-rateable

As with most Laravel packages, if you're using Laravel 5.5 or later, the package will be auto-discovered (learn more if this is new to you).

If you're using a version of Laravel before 5.5, you'll need to register the Rateable service provider. In your config/app.php add 'willvincent\Rateable\RateableServiceProvider' to the end of the $providers array.

'providers' => [

    Illuminate\Foundation\Providers\ArtisanServiceProvider::class,
    Illuminate\Auth\AuthServiceProvider::class,
    ...
    willvincent\Rateable\RateableServiceProvider::class,

],

Getting started

After the package is correctly installed, you need to generate the migration.

php artisan rateable:migration

It will generate the <timestamp>_create_ratings_table.php migration. You may now run it with the artisan migrate command:

php artisan migrate

After the migration, one new table will be present, ratings.

Usage

In order to mark a model as "rateable", import the Rateable trait.

<?php namespace App;

use willvincent\Rateable\Rateable;
use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    use Rateable;

}

Now, your model has access to a few additional methods.

First, to add a rating to your model:

$post = Post::first();

$rating = new willvincent\Rateable\Rating;
$rating->rating = 5;
$rating->user_id = \Auth::id();

$post->ratings()->save($rating);

dd(Post::first()->ratings);

Once a model has some ratings, you can fetch the average rating:

$post = Post::first();

dd($post->averageRating);
// $post->averageRating() also works for this.

Also, you can fetch the rating percentage. This is also how you enforce a maximum rating value.

$post = Post::first();

dd($post->ratingPercent(10)); // Ten star rating system
// Note: The value passed in is treated as the maximum allowed value.
// This defaults to 5 so it can be called without passing a value as well.

// $post->ratingPercent(5) -- Five star rating system totally equivilent to:
// $post->ratingPercent()

You can also fetch the sum or average of ratings for the given rateable item the current (authorized) has voted/rated.

$post = Post::first();

// These values depend on the user being logged in,
// they use the Auth facade to fetch the current user's id.


dd($post->userAverageRating); 

dd($post->userSumRating);
