Question

我似乎无法让哨兵工作。我一直收到这个错误：A hasher has not been provided for the user.有谁知道会发生什么事情？

The error log

我在OS X 10.9上运行MAMP。我使用的是PHP 5.4.4 已安装并启用MCrypt。尝试在创建新用户时散列密码时会发生此错误。我们的项目使用laravel Sentry插件。这是控制器：

<?php

use Auth, BaseController, Form, Input, Redirect, Sentry, View;

class AuthController extends BaseController {

        public function register()
        {
            return View::make('Auth.register');
        }

        public function handleRegister()
        {
               $validator = Validator::make(Input::all(), User::$rules);

                if ($validator->passes()) {
                    //The registration has passed, create a user

            $user = new User;
                    $user->first_name = Input::get('first_name');
                    $user->last_name = Input::get('last_name');
                    $user->email = Input::get('email');
                    $user->password = Hash::make(Input::get('password'));
                    $user->activated = 1;
                    $user->save();

            //grabbing the Sentry model of the user so we can save it to the appropriate group
            $sentryUser = Sentry::findUserByLogin($user->email);

            if (Input::get('userType') == 'Promoter')
            {
              $group = 'Promoters';
            }
            else
            {
              $group = 'Agents';
            }

            // Find the group using the group id
            $group = Sentry::findGroupByName($group);

            // Assign the group to the user
           $sentryUser->addGroup($group);

                    return Redirect::action('AuthController@login')->with('message', 'Thanks for registering!');
                } else {
                // validation has failed, display error messages   
                    return Redirect::action('AuthController@register')->with('message', 'The following errors occurred')->withErrors($validator)->withInput();

                }
        }

        /**

Answer 1

问题是，当您将Sentry配置为使用User.php作为模型时，它会丢失Sentry hasher。解决方案是在用户注册时设置哈希

$user->setHasher(new Cartalyst\Sentry\Hashing\NativeHasher);

Answer 2

@Dylan Pierce建议的更好的替代方法是直接在用户模型的构造函数中设置哈希。

public function __construct()
{
    $this->setHasher(new \Cartalyst\Sentry\Hashing\NativeHasher);
}

请注意Sentry提供了其他不同的Hashers，您可以在此目录中找到它们： vendor/cartalyst/sentry/src/Cartalyst/Sentry/Hashing/

完整示例：

use Cartalyst\Sentry\Users\Eloquent\User;
use Cartalyst\Sentry\Hashing\NativeHasher as SentryNativeHasher;

class Subscriber extends User
{

     public function __construct()
     {
          $this->setHasher(new SentryNativeHasher);
     }

}

Answer 3

如果要对整个模型使用setHasher方法;为了保留Eloquent类的构造函数，使用静态方法'boot'，它将从Eloquent构造函数类运行：

public static function boot()
{
    static::setHasher(new \Cartalyst\Sentry\Hashing\NativeHasher);
}

Answer 4

最好的方法是使用Eloquent启动功能（如@browno所示），但也使用父类的hasher，因此仍将使用hasher的Sentry配置设置。另外，请记住调用父启动功能，否则可能会破坏功能。示例代码：

use Cartalyst\Sentry\Users\Eloquent\User as SentryUser;

class User extends SentryUser {
    protected static function boot() {
        parent::boot();

        static::setHasher(parent::getHasher());
    }
}

没有为用户提供哈希
