Laravel 验证唯一规则反射类异常答案

【问题标题】：Laravel validation unique rule reflection class exceptionLaravel 验证唯一规则反射类异常
【发布时间】：2019-09-19 11:49:05
【问题描述】：

我正在尝试为电子邮件地址字段设置唯一规则，但我遇到了 ReflectionException，因为验证表名称被强制转换为一个类。查看文档，这应该只是将其转换为表格。..

Laravel 版本为：5.7。

验证规则如下：

$this->validate($request, [
    'email' => 'unique:users',
    'password' => 'same:password_confirmation'
]);

$this 是控制器，我也尝试过使用 Illuminate\Http\Request;结果一样。

我得到的堆栈跟踪如下：

ReflectionException thrown with message "Class users does not exist"

我可能只是忽略了一些东西，但是经过一小时的调试后，我决定发布一个问题。谢谢！ :)

【问题讨论】：

你能添加你的控制器吗？
你能发composer.json的内容吗？
您确定users 表存在吗？

标签： php laravel

【解决方案1】：

解决我的问题的原因如下：

我的供应商文件夹中仍然保留了laravel-doctrine/orm 的一部分，这可能是因为我删除了依赖项，但从未运行 composer 来反映这些更改。因此运行composer install 解决了我的问题！

【讨论】：

【解决方案2】：

在使用 laravel-doctrine 的类型中，验证接受两个参数：

正如Documentation 所说：

/**
 * Store a new blog post.
 *
 * @param  Request  $request
 * @return Response
 */
public function store(Request $request)
{
    $this->validate($request, [
        'username' => 'required|unique:App\User,username',
    ]);
}

因此在你的情况下：

$this->validate($request, [
        'email' => 'required|unique:App\User,email',
    ]);

【讨论】：

奇怪的是，我实际上并没有使用 Doctrine。我在任何地方都没有 laravel-doctrine 依赖。
@JKaan，让我们再次查看您的 Stacktrace。因此，我建议使用此解决方案。
@JKaan，检查'doctrine_presence_verifier' => false，在doctrine.php，它必须设置为false。
@Moshen，我什至似乎没有教义.php。这应该在我认为的配置目录中？
@JKaan，我再次检查了您的问题，如果您使用 Eloquent 尝试删除“laravel-doctrine”包，请使用我的解决方案。
