README

This package gives your laravel project the ability to create and manage an upvote/downvote system for user created content. This project was inspired by Reddit karma.

Main Features in this Package

This package will provide you with 2 table migrations which will create a votes table (dd_votes) and a voter table (dd_voters).

You will also be given access to two traits:

Votable -> Adds upvoting and downvoting functionality to a votable object such as a blog post, comment, photos, or anything else with a user_id representing an owner.

CanVote -> To be applied to your User model. Adds additional functionality to your user which lets them manage their ability to vote and provides a votable score (calculated from votes others have casted on their votable objects).

You can also access the two models Vote and Voter.

A config file vote.php will be published to your config directory.

Installation

Via Composer

$ composer require daydevelops/vote
$ php artisan vendor:publish
$ php artisan migrate

Usage

Apply the Votable Trait

Suppose we have a blog and users can create comments. If we want to allow users to upvote and downvote comments, we simply add the Votable trait.

...
use Daydevelops\Vote\Traits\Votable;

class Comment extends Model
{
    use Votable;

    ...

}

Apply the CanVote Trait

The CanVote trait should be applied to your User model.

...
use Daydevelops\Vote\Traits\CanVote;

class User extends Model
{
    use CanVote;

    ...

}
