The Favoriter

The favoriter is the user in which is favoriting objects.

Add the Favoriter Trait to your desired User model.

use Servnx\GetCandyFavorite\Traits\Favoriter;

class User extends Authenticatable
{
    use HasFactory,
        GetCandyUser,
        Favoriter,
        Billable,
        Notifiable;
       
    ...
}

Usage

Supported GetCandy Favoriteable Models.

GetCandy\Models\Product::class
... more to come ...

Adding favoritebale to your own Models.

use Illuminate\Database\Eloquent\Model;
use Servnx\GetCandyFavorite\Traits\Favoriteable;

class Post extends Model
{
    use Favoriteable;
    
    ...
}

API

$user = User::find(1);
$product = Product::find(2);

$user->favorite($product);
$user->unfavorite($product);
$user->toggleFavorite($product);
$user->getFavoriteItems(Product::class)

$user->hasFavorited($product);
$product->hasBeenFavoritedBy($user);

Get Favoriters example:

foreach($product->favoriters as $user) {
    ...
}

Get Favorite Model from User.

This will return a Illuminate\Database\Eloquent\Builder instance.

$favoriteItems = $user->getFavoriteItems(Product::class);

// more examples
$favoriteItems->get();
$favoriteItems->paginate();
$favoriteItems->find(1)->get();

Aggregations

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

// how many Products has this user favorited ?
$user->favorites()->withType(Product::class)->count();

// how many users favorited this product ?
$product->favoriters->count();

List with *_count attribute:

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

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


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

foreach($products as $product) {
    echo $product->favoriters_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 Models

$product = Product::find(1);

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

$product->toArray();

// example result
[
    "id" => 1
    ...
    "has_favorited" => true
],

For Collection | Paginator | LengthAwarePaginator | array:

$products = Product::oldest('id')->get();

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

$products->toArray();

// example result
[
  [
    "id" => 1
    ...
    "has_favorited" => true
  ],
  [
    "id" => 2
    ...
    "has_favorited" => false
  ],
  [
    "id" => 3
    ...
    "has_favorited" => true
  ],
]

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();

// Favoriteable
$products = Product::with('favorites')->get();
$products = Product::with('favoriters')->get();

Events

Event	Description
Servnx\GetCandyFavorite\Events\Favorited	Triggered when the relationship is created.
Servnx\GetCandyFavorite\Events\Unfavorited	Triggered when the relationship is deleted.
