我已經active_admin形式爲我的畫廊模式:active_admin形式和顯示圖像

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 

如果我編輯的畫廊,就說明我要圖像文件上傳的投入,但我也想顯示圖像縮略圖如果可能的話,像這樣:

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

任何想法我該怎麼做?型號有:

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才能做到這一點
