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:

// Voter
$users = User::with('votes')->get();

foreach($users as $user) {
    $user->hasVoted($comment);
}

// Votable
$comments = Comment::with('voters')->get();

foreach($comments as $comment) {
    $comment->isVotedBy($user);
}

Events

| Event | Description | | --- | --- | | Jcc\LaravelVote\Events\Voted | Triggered when the relationship is created or updated. | | Jcc\LaravelVote\Events\CancelVoted | Triggered when the relationship is deleted. |
