Laravel 管理员：异常 'BadMethodCallException' 带有消息'调用未定义的方法 Illuminate\Database\Query\Builder::

Question

我正在尝试在我的一张表的配置中使用 Laravel 4 管理员的全局操作（'global_actions' 数组），无论我调用什么方法，我都会感到害怕：

local.ERROR: exception 'BadMethodCallException' with message 'Call to undefined method Illuminate\Database\Query\Builder::doNothing()' in C:\xampp\htdocs\tikitour\vendor\laravel\framework\src\Illuminate\Database\Query\Builder.php:2117

config 数组在下面，'permission' 属性工作得很好，我现在有了它，所以 doNothing() 方法只返回 true：

'global_actions' => array(
        //Importing data via xls upload 
        'use_upload' => array(
            'title' => 'Use Upload',
            'messages' => array(
                'active' => 'Uploading...',
                'success' => 'Uploaded',
                'error' => 'There was an error while Uploading',
            ),
            'permission' => function($model)
            {                           
                return $model->hasUpload();             
            },
            //the model is passed to the closure
            'action' => function($model)
            {   

                $model->doNothing();                               
            }
        ),

    ),      

最重要的是，这在管理员之外可以完美运行。看起来模型的方法必须以某种方式向 Illuminate 注册，但我认为情况并非如此，因为 ->hasUpload() 已被识别并且工作正常。

问题已解决：我混合了 global_action 和 custom_action，这个配置选项传递了一个查询构建器的实例，而不是被表示的模型。我在函数中实例化了我需要的模型：

//the Eloquent query builder is passed to the closure
'action' => function($query)
{                   
    $country = new Countries();
    return $country->processUpload();
}
