cannot use class because it is not a trait
提问by arrowill12
I have followed the tutorial hereon building a validation service for laravel. I am having issues now when trying to call the validator from one of my controllers. I am seeing the error:
我已经按照这里的教程来为 laravel 构建验证服务。我现在在尝试从我的一个控制器调用验证器时遇到问题。我看到错误：
validController cannot use Portal\Service\Validation\Laravel\AppInstancesValidator - it is not a trait
validController cannot use Portal\Service\Validation\Laravel\AppInstancesValidator - it is not a trait
here is my controller:
这是我的控制器：
class validController extends BaseController {
use \Portal\Service\Validation\Laravel\AppInstancesValidator;
public function validateInstance() {
$post = Input::all();
$instVal = new AppInstancesValidator( App::make('validator'));
return $instVal->with($post)->passes();
}
}
and my validator:
和我的验证器：
namespace Portal\Service\Validation\Laravel;
use Portal\Service\Validation\ValidableInterface;
class AppInstancesValidator extends LaravelValidator implements ValidableInterface {
protected $rules = array(
'app_name' => 'required',
'app_instance_name' => 'required',
'app_instance_ip' => 'required|ip'
);
}

Try putting the usebefore the classdeclaration:
尝试将 放在声明use之前class：
<?php // namespace Portal\Controllers;
use \Portal\Service\Validation\Laravel\AppInstancesValidator;
class validController extends BaseController {
public function validateInstance() {}
}

Your 'use' statement should be above the class definition of validController
您的“使用”语句应位于 validController 的类定义之上
