在Laravel中，有没有办法找出“firstOrCreate”是否创建或是否找到了该行？

如果在当前生命周期中创建了模型，则模型的属性将设置为 。否则，该属性将设置为 。wasRecentlyCreatedtruefalse

换句话说，假设您有一个用户的电子邮件。bob@example

$user = User::firstOrCreate(['email' => 'bob@example.com']);

// the below will dump out false because this entry already existed
var_dump($user->wasRecentlyCreated);

现在，让我们说不存在。new@example.com

$user2 = User::firstOrCreate(['email' => 'new@example.com']);

// the below will dump out true because this user was created
// in the current request lifecycle
var_dump($user2->wasRecentlyCreated);
