Question

我正在尝试通过回形针在活动管理中提取图像

column "Images" do |m|
  m.member_images.each do |img|
    image_tag(img.photo.url(:thumb))
  end
end

但在我看来，我得到的不是图像本身

[#<MemberImage id: 2, member_id: 2, created_at: "2014-02-18 21:37:27", updated_at: "2014-02-18 21:37:27", photo_file_name: "associations.jpg", photo_content_type: "image/jpeg", photo_file_size: 140780, photo_updated_at: "2014-02-18 21:37:27">]

我的模型设置如此

class MemberImage < ActiveRecord::Base
belongs_to :member
has_attached_file :photo, styles: { thumb: '100x100#' }
end


class Member < ActiveRecord::Base

has_many :member_images, dependent: :destroy
accepts_nested_attributes_for :member_images, allow_destroy: true

end

图像无法显示会有任何原因吗？

Answer 1

所以经过一些更多的环顾四周，我发现这是有效的

column "Images" do |m|
 ul do 
   m.member_images.each do |img|
     li do
      image_tag(img.photo.url(:thumb))
    end
   end
 end
end

虽然我不确定为什么会有所作为

图像无法呈现Active Admin和Paperclip
