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);
$post->hasBeenFavoritedBy($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;
}


// for Favoriteable models:
$posts = Post::withCount('favoriters')->get();

foreach($posts as $post) {
    echo $post->favorites_count;
}

Attach user favorite status to favoriteable collection

You can use Favoriter::attachFavoriteStatus($favoriteables) to attach the user favorite status, it will set has_favorited attribute to each model of $favoriteables:

For model

$post = Post::find(1);

$post = $user->attachFavoriteStatus($post);

// result
[
    "id" => 1
    "title" => "Add socialite login support."
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_favorited" => true
 ],

For Collection | Paginator | LengthAwarePaginator | array:

$posts = Post::oldest('id')->get();

$posts = $user->attachFavoriteStatus($posts);

$posts = $posts->toArray();

// result
[
  [
    "id" => 1
    "title" => "Post title1"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_favorited" => true
  ],
  [
    "id" => 2
    "title" => "Post title2"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_favorited" => false
  ],
  [
    "id" => 3
    "title" => "Post title3"
    "created_at" => "2021-05-20T03:26:16.000000Z"
    "updated_at" => "2021-05-20T03:26:16.000000Z"
    "has_favorited" => true
  ],
]

For pagination

$posts = Post::paginate(20);

$user->attachFavoriteStatus($posts);

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 = User::with('favorites')->get();

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

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