Introduction

This light package gives Eloquent models the ability to manage their acquaintances and other cool useful stuff. You can easily design your social-like System (Facebook, Twitter, Foursquare...etc).

Acquaintances includes:

• Send Friend Requests
• Accept Friend Requests
• Deny Friend Requests
• Block a User
• Group Friends
• Rate a User or a Model, supporting multiple aspects
• Follow a User or a Model
• Like a User or a Model
• Subscribe a User or a Model
• Favorite a User or a Model
• Vote (Upvote & Downvote a User or a Model)

Installation

First, install the package through Composer.

$ composer require elemenx/laravel-acquaintances

Laravel 5.8 and up => version 2.x (branch master)

Laravel 5.7 and below => version 1.x (branch v1)

Laravel 5.4 and down

Then include the service provider inside config/app.php.

'providers' => [
//    ...
    ElemenX\Acquaintances\AcquaintancesServiceProvider::class,
//    ...
];

Publish config and migrations:

$ php artisan vendor:publish --provider="ElemenX\Acquaintances\AcquaintancesServiceProvider"

Configure the published config in:

config\acquaintances.php

Finally, migrate the database to create the table:

$ php artisan migrate

Setup a Model

Example:

use ElemenX\Acquaintances\Traits\Friendable;
use ElemenX\Acquaintances\Traits\CanFollow;
use ElemenX\Acquaintances\Traits\CanBeFollowed;
use ElemenX\Acquaintances\Traits\CanLike;
use ElemenX\Acquaintances\Traits\CanBeLiked;
use ElemenX\Acquaintances\Traits\CanRate;
use ElemenX\Acquaintances\Traits\CanBeRated;
//...

class User extends Model
{
    use Friendable;
    use CanFollow, CanBeFollowed;
    use CanLike, CanBeLiked;
    use CanRate, CanBeRated;
    //...
}

All available APIs are listed below for Friendships & Interactions.

To get a collection of friend models (ex. User) use the following methods:

getFriends()

$user->getFriends();
// or panigated
$user->getFriends($perPage = 20, $group_name);
// or paginated with certain fields 
$user->getFriends($perPage = 20, $group_name, $fields = ['id','name']);

• $perPage: integer (default: 0), Get values paginated
• $group_name: string (default: ''), Get collection of Friends in specific group paginated
• $fields: array (default: ['*']), Specify the desired fields to query.

getFriendsOfFriends()

$user->getFriendsOfFriends();
// or
$user->getFriendsOfFriends($perPage = 20);
// or 
$user->getFriendsOfFriends($perPage = 20, $fields = ['id','name']);

Friend Groups:

The friend groups are defined in the config/acquaintances.php file. The package comes with a few default groups. To modify them, or add your own, you need to specify a slug and a key.

// config/acquaintances.php
//...
'groups' => [
    'acquaintances' => 0,
    'close_friends' => 1,
    'family' => 2
];

Since you've configured friend groups, you can group/ungroup friends using the following methods.

Group a Friend

$user->groupFriend($friend, $group_name);

Remove a Friend from family group

$user->ungroupFriend($friend, 'family');

Remove a Friend from all groups

$user->ungroupFriend($friend);

Get the number of Friends in specific group

$user->getFriendsCount($group_name);

To filter friendships by group you can pass a group slug.

$user->getAllFriendships($group_name);
$user->getAcceptedFriendships($group_name);
$user->getPendingFriendships($group_name);
...

Parameters

All the above mentioned methods of creating relationships, such as 'follow', 'like', 'unfollow', 'unlike', their syntax is as follows:

follow(array|int|\Illuminate\Database\Eloquent\Model $targets, $class = __CLASS__)

So you can call them like this:

// id / int|array
$user->follow(1); // targets: 1, $class = App\User
$user->follow(1, App\Post::class); // targets: 1, $class = App\Post
$user->follow([1, 2, 3]); // targets: [1, 2, 3], $class = App\User

// Model
$post = App\Post::find(7);
$user->follow($post); // targets: $post->id, $class = App\Post

// Model array
$posts = App\Post::popular()->get();
$user->follow($posts); // targets: [1, 2, ...], $class = App\Post

Query relations

$followers = $user->followers;
$followers = $user->followers()->where('id', '>', 10)->get();
$followers = $user->followers()->orderByDesc('id')->get();
$followers = $user->followers()->paginate(10);

You may use the others in the same way.

Working with model

use ElemenX\Acquaintances\Models\InteractionRelation;

// Get most popular object
// 1- All types
$relations = InteractionRelation::popular()->get();

// 2- subject_type = App\Post
$relations = InteractionRelation::popular(App\Post::class)->get(); 

// 3- subject_type = App\User
$relations = InteractionRelation::popular('user')->get();
 
// 4- subject_type = App\Post
$relations = InteractionRelation::popular('post')->get();

// 5- Pagination
$relations = InteractionRelation::popular(App\Post::class)->paginate(15);
