使用Laravel Validator模块时没有错误消息文本

我设法在我的项目中使用Laravel验证模块:

<?php
namespace Models;
use Illuminate'Database'Eloquent'Model as eModel;
use Illuminate'Validation'Factory as ValidatorFactory;
use Symfony'Component'Translation'Translator;
class AbstractModel extends  eModel {

public function validate($data)
{
    $factory = new ValidatorFactory(new Translator('en'));
    $v = $factory->make($data, $this->rules);
    return $v;
}
public function save() {
    $validator = $this->validate($this->toArray());
    if(!$validator->passes())
    {
        $messages = $validator->messages();
        print_r($messages);
        die();
    }
    parent::save();
}

}

如果我使用它，我会得到以下输出:

Illuminate'Support'MessageBag Object ( [messages:protected] => Array ( [email] => Array ( [0] => validation.required ) ) [format:protected] => :message )

我不知道为什么模块没有得到默认的错误字符串。我很确定模块工作正常因为如果我尝试定义一些自定义字符串，像这样:

    $message = array(
        'unique' => 'FOO',
        'email' => ':attribute WORNG!!!!!',
        'required' => ':attribute MUST WRITE EMAIL!!!!'
    );
    $factory = new ValidatorFactory(new Translator('en'));
    $v = $factory->make($data, $this->rules, $message);

我得到了输出:

Illuminate'Support'MessageBag Object ( [messages:protected] => Array ( [email] => Array ( [0] => email MUST WRITE EMAIL!!!! ) ) [format:protected] => :message )

我错过了什么?
