Laravel Subscribe

Introduction

IMPORTANT: This is not a package for managing subscribers related to memberships and payed methods. It is used for managing user/subscriber relations just like in YouTube for example, where the model can be subscribed by user.

This package is based on an idea and an architecture of the Laravel Love package, although the functionality is different.

Features

• Uses UUIDs instead of integers (your user model must use them as well!)
• Designed to work with Laravel Eloquent models.
• Using contracts to keep high customization capabilities.
• Using traits to get functionality out of the box.
• Most part of the the logic is handled by the SubscribeableService.
• Has Artisan command gosubscribe:recount {model?} to re-fetch subscribe counters.
• Subscribes for one model are mutually exclusive.
• Get Subscribeable models ordered by subscribe count.
• Events for subscribe, unsubscribe methods.
• Following PHP Standard Recommendations:
  • PSR-1 (Basic Coding Standard).
  • PSR-2 (Coding Style Guide).
  • PSR-4 (Autoloading Standard).
• Covered with unit tests.

Installation

First, pull in the package through Composer.

$ composer require gorankrgovic/laravel-subscribe

Perform Database Migration

At last you need to publish and run database migrations.

$ php artisan migrate

If you want to make changes in migrations, publish them to your application first.

$ php artisan vendor:publish --provider="Gox\Laravel\Subscribe\Providers\SubscribeServiceProvider" --tag=migrations

Usage

Prepare Subscriber Model

Use Gox\Contracts\Subscribe\Subscriber\Models\Subscriber contract in model which will get subscribes behavior and implement it or just use Gox\Laravel\Subscribe\Subscriber\Models\Traits\Subscriber trait.

use Gox\Contracts\Subscribe\Subscriber\Models\Subscriber as SubscriberContract;
use Gox\Laravel\Subscribe\Subscriber\Models\Traits\Subscriber;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements SubscriberContract
{
    use Subscriber;
}

Prepare Subscribeable Model

Use Gox\Contracts\Subscribe\Subscribeable\Models\Subscribeable contract in model which will get subscribes behavior and implement it or just use Gox\Laravel\Subscribe\Subscribeable\Models\Traits\Subscribeable trait.

use Gox\Contracts\Subscribe\Subscribeable\Models\Subscribeable as SubscribeableContract;
use Gox\Laravel\Subscribe\Subscribeable\Models\Traits\Subscribeable;
use Illuminate\Database\Eloquent\Model;

class Article extends Model implements SubscribeableContract
{
    use Subscribeable;
}

Available Methods

Subscribes

Subscribe model

$user->subscribe($article);

$article->subscrubeBy(); // current user
$article->subscribeBy($user->id);

Remove subscribe mark from model

$user->unsubscribe($article);

$article->unsubscribeBy(); // current user
$article->unsubscribeBy($user->id);

Get model subscribe count

$article->subcribesCount;

Get model subscribes counter

$article->subscribesCounter;

Get subscribes relation

$article->subscribes();

Get iterable Illuminate\Database\Eloquent\Collection of existing model subscribes

$article->subscribes;

Boolean check if user subscribed to model

$user->hasSubscribed($article);

$article->subscribed; // current user
$article->isSubscribedBy(); // current user
$article->isSubscribedBy($user->id);

Checks in eager loaded relations subscribes first.

Get collection of users who subscribed to model

$article->collectSubscribers();

Delete all subscribers for model

$article->removeSubscribes();

Scopes

Find all articles subscribed by user

Article::whereSubscribedBy($user->id)
    ->with('subscribesCounter') // Allow eager load (optional)
    ->get();

Fetch Subscribeable models by subscribes count

$sortedArticles = Article::orderBySubscribesCount()->get();
$sortedArticles = Article::orderBySubscribesCount('asc')->get();

Uses desc as default order direction.

Events

On each subscribe added \Gox\Laravel\Subscribe\Subscribeable\Events\SubscribeableWasSubscribed event is fired.

On each subscribe removed \Gox\Laravel\Subscribe\Subscribeable\Events\SubscribeableWasUnsubscribed event is fired.

Console Commands

Recount subscribers of all model types

$ gosubscribe:recount

Recount of concrete model type (using morph map alias)

$ gosubscribe:recount --model="article"

Recount of concrete model type (using fully qualified class name)

$ gosubscribe:recount --model="App\Models\Article"

Extending

You can override core classes of package with your own implementations:

• Gox\Laravel\Subscribe\Subscribe\Models\Subscribe
• Gox\Laravel\Subscribe\SubscribeCounter\Models\SubscribeCounter
• Gox\Laravel\Subscribe\Subscribeable\Services\SubscribeableService

Note: Don't forget that all custom models must implement original models interfaces.

To make it you should use container binding interfaces to implementations in your application service providers.

Use model class own implementation

$this->app->bind(
    \Gox\Contracts\Subscribe\Subscribe\Models\Subscribe::class,
    \App\Models\CustomSubscribe::class
);

After that your CustomSubscribe class will be instantiable with helper method app().

$model = app(\Gox\Contracts\Subscribe\Subscribe\Models\Subscribe::class);

Testing

Run the tests with:

$ vendor/bin/phpunit
