Question

我目前在art和art_pic_attachment之间有HABTM关系（图像）。创建对象没有问题但是当我想删除图像时 - 我找不到任何显示如何删除图像的干净文档。我尝试了_destroy选项，但没有任何反应。有任何线索如何解决这个问题？

ActiveAdmin.register Art do

permit_params :art_pic_attachments_attributes: [:id, :picture, :_destroy]

 form(html: { multipart: true }) do |f|
    f.inputs do

        f.has_many :art_pic_attachments, allow_destroy: true, heading: 'Images' do |ff|
            ff.file_field :picture, required: true, heading: "Pictures"
        end

    end
        f.actions
 end

型号：

class Art < ApplicationRecord
        has_many :art_pic_attachments, dependent: :destroy
        accepts_nested_attributes_for :art_pic_attachments, allow_destroy: true  
    end

此wiki article讨论了如何使用Paperclip执行此操作并覆盖＆lt; attachment_name＆gt; _attributes =，例如。

def attachment_attributes=(attributes)
  attachment.clear if has_destroy_flag?(attributes) && !attachment.dirty?
end

如何在ActiveAdmin表单中删除图像？
