Parameters

All of the above mentioned methods of creating relationships, such as 'follow', 'like', 'unfollow', 'unlike', their syntax is as follows:

follow(array|int|\Illuminate\Database\Eloquent\Model $targets, $class = __CLASS__)

So you can call them like this:

// Id / Id array
$user->follow(1); // targets: 1, $class = App\User
$user->follow(1, App\Post::class); // targets: 1, $class = App\Post
$user->follow([1, 2, 3]); // targets: [1, 2, 3], $class = App\User

// Model
$post = App\Post::find(7);
$user->follow($post); // targets: $post->id, $class = App\Post

// Model array
$posts = App\Post::popular()->get();
$user->follow($posts); // targets: [1, 2, ...], $class = App\Post

Query relations

$followers = $user->followers
$followers = $user->followers()->where('id', '>', 10)->get()
$followers = $user->followers()->orderByDesc('id')->get()

The other is the same usage.

Working with model.

use Overtrue\LaravelFollow\FollowRelation;

// get most popular object

// all types
$relations = FollowRelation::popular()->get();

// followable_type = App\Post
$relations = FollowRelation::popular(App\Post::class)->get(); 

// followable_type = App\User
$relations = FollowRelation::popular('user')->get();
 
// followable_type = App\Post
$relations = FollowRelation::popular('post')->get();

// Pagination
$relations = FollowRelation::popular(App\Post::class)->paginate(15);
