Usage

Traits

Overtrue\LaravelFavorite\Traits\Favoriter

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Overtrue\LaravelFavorite\Traits\Favoriter;

class User extends Authenticatable
{
    use Favoriter;
    
    <...>
}

Overtrue\LaravelFavorite\Traits\Favoriteable

use Illuminate\Database\Eloquent\Model;
use Overtrue\LaravelFavorite\Traits\Favoriteable;

class Post extends Model
{
    use Favoriteable;

    <...>
}

API

$user = User::find(1);
$post = Post::find(2);

$user->favorite($post);
$user->unfavorite($post);
$user->toggleFavorite($post);
$user->getFavoriteItems(Post::class)

$user->hasFavorited($post); 
$post->isFavoritedBy($user); 

Get object favoriters:

foreach($post->favoriters as $user) {
    // echo $user->name;
}

Get Favorite Model from User.

Used Favoriter Trait Model can easy to get Favoriteable Models to do what you want. *note: this method will return a Illuminate\Database\Eloquent\Builder *

$user->getFavoriteItems(Post::class);

// Do more
$favortePosts = $user->getFavoriteItems(Post::class)->get();
$favortePosts = $user->getFavoriteItems(Post::class)->paginate();
$favortePosts = $user->getFavoriteItems(Post::class)->where('title', 'Laravel-Favorite')->get();

Aggregations

// all
$user->favorites()->count(); 

// with type
$user->favorites()->withType(Post::class)->count(); 

// favoriters count
$post->favoriters()->count();

List with *_count attribute:

$users = User::withCount('favorites')->get();

foreach($users as $user) {
    echo $user->favorites_count;
}

N+1 issue

To avoid the N+1 issue, you can use eager loading to reduce this operation to just 2 queries. When querying, you may specify which relationships should be eager loaded using the with method:

// Favoriter
$users = App\User::with('favorites')->get();

foreach($users as $user) {
    $user->hasFavorited($post);
}

// Favoriteable
$posts = App\Post::with('favorites')->get();
// or 
$posts = App\Post::with('favoriters')->get();

foreach($posts as $post) {
    $post->isFavoritedBy($user);
}

Events

Event Description
Overtrue\LaravelFavorite\Events\Favorited Triggered when the relationship is created.
Overtrue\LaravelFavorite\Events\Unfavorited Triggered when the relationship is deleted.
