active_admin表单并显示图像

我的Gallery模型有active_admin表单:

form do |f|
  f.inputs "Gallery" do
    f.input :title
    f.input :description
    f.input :file
  end
  f.has_many :images do |ff|
    ff.input :file
  end
  f.actions
end

如果我编辑图库,它会向我显示图像文件上传的输入,但我还想在可能的情况下显示图像缩略图,例如:

f.has_many :images do |ff|
  image_to ...
  ff.input :file
end

知道我该怎么办?模型是:

class Image < ActiveRecord::Base
  attr_accessible :gallery_id, :file
  belongs_to :gallery

  mount_uploader :file, FileUploader
end

class Gallery < ActiveRecord::Base

  attr_accessible :description, :title, :file, :images_attributes
  has_many :images
  accepts_nested_attributes_for :images, allow_destroy: true

  mount_uploader :file, FileUploader
end

你可能需要Javascript才能做到这一点
