Если у меня есть друг, я могу добавить его снова Laravel 5.1

У меня небольшая проблема. Я создал миграцию, модель и т. Д. Для друга, когда я добавляю друга, все в порядке, но я не знаю, как это сделать для конкретного пользователя в друзьях, тогда я не могу добавить его снова. Тогда просто не вижу кнопки.

Это моя кнопка:

@if($user->off_friends != 1)
@if(!\Auth::guest() && $user->id != \Auth::id())
@if($user->hasFriend($user->id))
{!! Form::open(array('method'=>'post', 'route' => array('store.friend', $user->id))) !!}
{!! Form::hidden('friend_id', $user->id) !!}
{!! Form::hidden('friend_name', $user->name) !!}
{!! Form::hidden('friend_avatar', $user->avatar) !!}
{!! Form::submit('Dodaj znajomego', ['class' => 'btn btn-primary btn-xs']) !!}
{!! Form::close() !!}<BR />
@endif
@endif
@endif

И это моя функция:

public function hasFriend($id)
{
foreach($this->friend as $friend)
{
if(\Auth::id() == $friend->user_id && $friend->friend_id == $id)
{
return true;
}
}

}

Я жду ответа, это важно, спасибо!

Модель друга:

use Illuminate\Database\Eloquent\Model;

class Friend extends Model
{
protected $fillable = ['friend_id', 'friend_name', 'added_at', 'friend_avatar'];

public function user()
{
return $this->belongsToMany('App\User')->withTimestamps();
}
}

ДОБАВЛЕНИЕ ОТВЕТА:

Я сделал это так:

@if(!\Auth::guest() && $user->id != \Auth::id() && !\Auth::user()->hasFriend($user->id))
