👍 User-like features for Laravel Application.
Installing
composer require overtrue/laravel-like -vvv
Configuration and Migrations
php artisan vendor:publish --provider="Overtrue\LaravelLike\LikeServiceProvider"
Usage
Traits
Overtrue\LaravelLike\Traits\Liker
use Illuminate\Notifications\Notifiable; use Illuminate\Contracts\Auth\MustVerifyEmail; use Illuminate\Foundation\Auth\User as Authenticatable; use Overtrue\LaravelLike\Traits\Liker; class User extends Authenticatable { use Liker; <...> }
Overtrue\LaravelLike\Traits\Likeable
use Illuminate\Database\Eloquent\Model; use Overtrue\LaravelLike\Traits\Likeable; class Post extends Model { use Likeable; <...> }
API
$user = User::find(1); $post = Post::find(2); $user->like($post); $user->unlike($post); $user->toggleLike($post); $user->hasLiked($post); $post->isLikedBy($user);
Get user likes with pagination:
$likes = $user->likes()->with('likeable')->paginate(20); foreach ($likes as $like) { $like->likeable; // App\Post instance }
Get object likers:
foreach($post->likers as $user) { // echo $user->name; }
with pagination:
$likers = $post->likers()->paginate(20); foreach($likers as $user) { // echo $user->name; }
Aggregations
// all $user->likes()->count(); // short way $user->totalLikes; // with type $user->likes()->withType(Post::class)->count(); // likers count $post->likers()->count(); // short way $post->totalLikers
List with *_count
attribute:
// likes_count $users = User::withCount('likes')->get(); foreach($users as $user) { // $user->likes_count; } // likers_count $posts = User::withCount('likers')->get(); foreach($posts as $post) { // $post->likes_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:
// Liker $users = App\User::with('likes')->get(); foreach($users as $user) { $user->hasLiked($post); } // Likeable $posts = App\Post::with('likes')->get(); // or $posts = App\Post::with('likers')->get(); foreach($posts as $post) { $post->isLikedBy($user); }
Of course we have a better solution, which can be found in the following section:
Attach user like status to likeable collection
You can use Liker::attachLikeStatus($likeables)
to attach the user like status, it will attach has_liked
attribute to each model of $likeables
:
For model
$post = Post::find(1); $post = $user->attachLikeStatus($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_liked" => true ],
For Collection | Paginator | LengthAwarePaginator | array
:
$posts = Post::oldest('id')->get(); $posts = $user->attachLikeStatus($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_liked" => true ], [ "id" => 2 "title" => "Post title2" "created_at" => "2021-05-20T03:26:16.000000Z" "updated_at" => "2021-05-20T03:26:16.000000Z" "has_liked" => fasle ], [ "id" => 3 "title" => "Post title3" "created_at" => "2021-05-20T03:26:16.000000Z" "updated_at" => "2021-05-20T03:26:16.000000Z" "has_liked" => true ], ]
For pagination
$posts = Post::paginate(20); $user->attachLikeStatus($posts);
