👍 为 Laravel 应用提供用户点赞功能。
安装
composer require overtrue/laravel-like -vvv
配置和迁移
php artisan vendor:publish --provider="Overtrue\LaravelLike\LikeServiceProvider"
使用方法
特性
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);
使用分页获取用户点赞
$likes = $user->likes()->with('likeable')->paginate(20); foreach ($likes as $like) { $like->likeable; // App\Post instance }
获取对象的点赞者
foreach($post->likers as $user) { // echo $user->name; }
使用分页
$likers = $post->likers()->paginate(20); foreach($likers as $user) { // echo $user->name; }
聚合
// 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
使用 *_count
属性列出
// 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 问题
为了避免 N+1 问题,可以使用预加载来将此操作减少到仅 2 次查询。在查询时,您可以使用 with
方法指定哪些关系应该被预加载
// 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); }
当然,我们还有一个更好的解决方案,可以在以下部分找到:
将用户点赞状态附加到可点赞集合
您可以使用 Liker::attachLikeStatus($likeables)
来附加用户点赞状态,它将为 $likeables
中的每个模型附加 has_liked
属性
对于模型
$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 ],
对于 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 ], ]
对于分页
$posts = Post::paginate(20); $user->attachLikeStatus($posts);
