Activeadmin - activestorage删除编辑多张照片

Question

我正在尝试使用activestorage删除从activeadmin上传的图像。我成功地在资源的展示视图和编辑视图中显示了所有图片，但如果我想要删除每个图片，我似乎找不到方法。我的模型代码如下：

  class Category < ApplicationRecord
    has_many_attached :images
  end

活动管理的资源文件：

   ActiveAdmin.register Category do

       permit_params :category_name, :description, :photo_cover, images: []

index do
    selectable_column
    id_column
    column :category_name
    column :created_at
    actions
end


show do |t|
    if t.photo_cover.attached? && t.images.attached?
        attributes_table do
          row :category_name
          row :description
          row "images" do |m|
                m.images.each do |img|
                       span do
                           image_tag(img)
                       end
                end
          end
        end
      else
        attributes_table do
          row :category_name
          row :description
        end
      end
  end


form :html => { :enctype => "multipart/form-data" } do |f|
      f.inputs "Basic Info" do
          f.input :category_name
          f.input :description 
      end

      f.inputs do
          f.input :images, as: :file, input_html: { multiple: true }
      end

       if f.object.images.attached?
            f.object.images.each do |img|
                span do
                   image_tag(img)
                 end
             end
        end

      f.actions
      end
 end

Thank you in advance!!

在ActiveAdmin模型中创建自定义路由，如此处所述：这里。

member_action :delete_category_image, method: :delete do
  @pic = ActiveStorage::Attachment.find(params[:id])
  @pic.purge_later
  redirect_back(fallback_location: edit_admin_category_path)   
end

在表单中使用 "do"：

f.object.images.each do |img|
  li class: "some_class" do
    figure do
      img src: rails_representation_path(img.variant(resize_to_fit: [200, 200])), alt: "Photo"
      figcaption img.blog.filename
    end

    a "Delete", src: delete_category_image_admin_category_path(img.id), "data-method": :delete, "data-confirm": "Are you sure?"
  end
end

实际上，应该是 a "Delete", href: delete... 而不是 a "Delete", src: delete，因为它是一个 a 标签。 - Hector Acosta
