使用回形針主動管理多個文件/圖像上傳

Question

我使用活動管理員，我需要上傳帶有大量圖像的圖庫。我該怎麼做？ 我的代碼：

class Gallery < ActiveRecord::Base 
    belongs_to :event 
    has_many :images 

    attr_accessible :name, :publish, :images, :image, :images_attributes 
    accepts_nested_attributes_for :images, allow_destroy: true 

    validates :name, presence: true 

end 

class Image < ActiveRecord::Base 
    belongs_to :gallery 

    attr_accessible :url 
    has_attached_file :url, :styles => { :medium => "300x300>", :thumb => "100x100>" } 
end 


ActiveAdmin.register Gallery do 
    form html: { multipart: true } do |f| 
      f.inputs do 
      f.input :name 
      f.input :images, as: :file, input_html: { multiple: true} 
      end    
      f.buttons 
    end 
end 

而且我有這樣的錯誤：

Image(#70319146544460) expected, got ActionDispatch::Http::UploadedFile(#70319105893880) 

Answer 1

試試這個：

ActiveAdmin.register Gallery do 
    form multipart: true do |f| 
    f.inputs do 
     f.input :name 

     f.has_many :images do |p| 
     p.input :url 
     end 
    end 

    f.actions 
    end 
end 

Answer 2

好吧，我設法解決它：

嘗試做如下：

ActiveAdmin.register Gallery do 
    form html: { multipart: true } do |f| 
    f.inputs do 
     f.input :name 
     file_field_tag("gallery_images_url", multiple: true, name: "gallery[gallery_images_attributes][][url]") 
    end    
    f.buttons 
    end 
end
