### Parameters
|
|
|
|
All of the above mentioned methods of creating relationships, such as 'follow', 'like', 'unfollow', 'unlike', their syntax is as follows:
|
|
|
|
```php
|
|
follow(array|int|\Illuminate\Database\Eloquent\Model $targets, $class = __CLASS__)
|
|
```
|
|
|
|
So you can call them like this:
|
|
|
|
```php
|
|
// 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
|
|
|
|
```php
|
|
$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.
|
|
|
|
```php
|
|
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);
|
|
|
|
```
|
|
