扩展 Symfony2 White October 管理捆绑包表单字段？
这个问题很具体。 我正在使用 Symfony2 White October Admin Bundle 为我的应用程序生成管理。 我想知道是否有人有这个包的经验并且知道如何修改添加到 Admin 类中的特定字段。该捆绑包没有很好地记录，我想知道是否有方法可以做到这一点，或者捆绑包核心是否需要扩展。
例如，我有一个扬声器实体，其中有一个字段存储某人头像的路径：
/**
* @var string $picturePath
*
* @ORM\Column(name="picture_path", type="string", length=128, nullable=false)
*/
private $picturePath;
然后在 Admin 类中我添加该字段：
protected function configure()
{
...
...
->addFields(array(
...
...
'picturePath'=> array("label" => "Avatar"),
));
}
是否有一种简单的方法来告诉捆绑包我希望该字段成为上传字段而不是文本字段，并定义提交表单后调用的额外方法？ （例如调整图像大小，存储它，然后将图像路径存储在数据库中）
This question is quite specific.
I'm using Symfony2 White October Admin Bundle for generating administration for my application.
I wonder if anyone has experience with this bundle and knows how to modify specific fields added to Admin class. The bundle is not documented very well and I'd like to know, if there are methods for doing this, or does the bundle core need to be extended.
For example I've got a Speaker entity with a field storing the path to one's avatar:
/**
* @var string $picturePath
*
* @ORM\Column(name="picture_path", type="string", length=128, nullable=false)
*/
private $picturePath;
Then in the Admin class I'm adding the field:
protected function configure()
{
...
...
->addFields(array(
...
...
'picturePath'=> array("label" => "Avatar"),
));
}
Is there an easy way to tell the bundle that I'd like this field to be an upload field instead of a text field, and define extra methods to call after submitting the form? (e.g. resize the image, store it, and then just store the image path in the DB)

由于我还没有找到任何解决方案，因此我必须强奸我的实体才能做到这一点。因此，我修改了基本的 setter 方法来调用实体内执行脏工作的其他方法。这不是一个解决方案，如果我能在这里找到更好的答案，我仍然会很高兴。
As I haven't found any solution yet, I had to rape my entities to do that. So I modified the basic setter methods to call other methods inside the entity that do the dirty job. This is not a solution, and I'll still be happy if I could find better answers here.
