heeey！）我试图制作一个画廊，但我在文件上传时遇到错误
模型库.rb
class Gallery < ActiveRecord::Base
acts_as_content_block
has_attached_file :avatar, :styles => { :thumb => "291x191#" }
#attr_accessible :images
has_many :images
accepts_nested_attributes_for :images, :allow_destroy => true
end
模型图像.rb
class Image < ActiveRecord::Base
belongs_to :gallery
#acts_as_content_block :belongs_to_gallery => true
has_attached_file :image, :styles => { :large => "640x480", :medium => "300x300>", :small => "100x100>" }
end
_form.html.erb
