Laravel更新模型具有唯一的属性验证规则 [英] Laravel update model with unique validation rule for attribute

问题描述

我有一个Laravel 用户模型，它在用户名和上有一个唯一的验证规则电子邮件。在我的存储库中，当我更新模型时，我重新验证字段，以便不需要规则验证的问题：

I have a laravel User model which has a unique validation rule on username and email. In my Repository, when I update the model, I revalidate the fields, so as to not have a problem with required rule validation:

public function update($id, $data) {
    $user = $this->findById($id);
    $user->fill($data);
    $this->validate($user->toArray());
    $user->save();
    return $user;
}

无法使用

ValidationException: {"username":["The username has already been taken."],"email":["The email has already been taken."]}

有没有办法修复这个优雅？

Is there a way of fixing this elegantly?

推荐答案

将当前更新的id实例附加到验证器。您可以传递实例的ID以忽略唯一的验证器。在验证器中使用参数来检测您是否正在更新或创建它，并在第一种情况下发送用户ID，然后您可以使用：

Append the currently updating id instance to the validator. You can pass the id of your instance to ignore the unique validator. In the validator use a parameter to detect if you are updating or creating it, and send the user id in the first case, then you can use:

强制一个唯一的规则可以忽略一个给定的ID

'email'=>'unique：users，email_address''$ userId

'email' => 'unique:users,email_address,'.$userId
