我正在尝试将设置传递给由cakephp-file-storage-plugin提供的行为。但是，无法识别这些设置。例如，如果我尝试通过将 GIF 文件排除在数组之外来排除它们，我仍然可以上传它们而不会出错。通过日志记录，我可以确认行为是否附加到模型，但是当我记录设置时，它们是空的。我知道插件/行为有效，但不幸的是，插件/行为的文档很少，所以我希望有人可以帮助我弄清楚我做错了什么。
下面是我的模型代码，我通过$actsAs传递设置以及完整的行为文件，我添加了日志记录，试图找出设置不起作用的原因。下面包含该日志记录的输出。 ListingPhoto 别名为 Photo ，作为另一个类的 hasMany 关联，这就是该名称出现在调试输出中的原因。但我无法完全解释为什么行为代码似乎为一个请求运行了这么多次。
我的模型：
<?php
App::uses('ImageStorage', 'FileStorage.Model');
class ListingPhoto extends ImageStorage {
public $name = 'ListingPhoto';
public $actsAs = array(
'Imagine.Imagine',
'FileStorage.UploadValidator' => array(
'localFile' => true,
'validate' => false,
'allowedExtensions' => array('jpg', 'jpeg', 'png')
),
);
public function upload($listing_id, $data) {
$data[$this->alias]['adapter'] = 'Local';
$data[$this->alias]['model'] = 'ListingPhoto';
$data[$this->alias]['foreign_key'] = $listing_id;
$this->create();
return $this->save($data);
}
public function afterDelete() {
parent::afterDelete();
$this->log($this->record);
StorageManager::adapter($this->record['Photo']['adapter'])->delete($this->record['Photo']['path']);
}
}
完整的行为文件，添加了我的日志记录：

如果我的插件，这不是问题。但是核心类Object::_mergeVars()，模型类继承了它。它以您获得的方式合并$actsAs property。
您使用已经存在的configureUploadValidation()行为方法之外，我无法在我的插件中解决此问题。明天我会把它作为注释添加到插件的文档中。
