访问semantic_fieds_for循环/formtastic中的对象

模型具有 Accepts_nested_attributes_for 关系，形式如下：

= semantic_form_for @obj, :url => path do |f|  
  =  f.inputs do
    = f.input :name
    = f.semantic_fields_for :photos do |p|
      = p.inputs :desc
  = f.buttons

该形式运行良好，一切都很好。但是，我想在现场附近显示每张照片，以便用户可以知道她要注释哪张照片。无论如何，要在 fields_for 循环内访问 photo.id 吗？

编辑：

有什么方法可以改变本示例中照片字段的渲染顺序。据我所知，到目前为止，这个顺序是相当随机的。

Model has accepts_nested_attributes_for for the relation and the form is as follows:

= semantic_form_for @obj, :url => path do |f|  
  =  f.inputs do
    = f.input :name
    = f.semantic_fields_for :photos do |p|
      = p.inputs :desc
  = f.buttons

The form works well and everything is fine. However, I would like to display each photo near the field, so the user could se which picture she is going to annotate. Is there anyway, to access photo.id inside the fields_for loop?

Edit:

Is there any way to alter the order in which photos fields will be rendered in this example. As far as I can tell till now, that order is pretty random.
