删除功能不适用于 rails 应用中的 Active Storage 图像

Question

我正在尝试为通过我的 rails 应用中的活动存储上传的图像创建删除功能。

我使用 devise 进行注册，使用 wicked wizard 进行多步操作，使用 cancancan 进行授权。我也在使用 rails 管理员。

但是我收到了这个错误，我不知道如何让它工作。我可以看到它与路线有关，但我不明白问题是什么以及如何解决。任何帮助将非常感激。

我的表格

<%= form_for @user, url: wizard_path, method: :put do |f| %>

<% if @user.clinic_images.attached? %>

<% @user.clinic_images.each do |image| %>

<%= image_tag(image.variant(resize: "100x100")) %>
<%= link_to ‘Delete this image’, delete_image_attachment_registration_url(image.signed_id),

method: :delete,

data: { confirm: ‘Are you sure?’ } %>

<% end %>

<% end %>

<% end %>

您的路由资源设置有误。

devise_scope :user do 
  scope module: :users do
    resources :registrations do
      member do
        delete :delete_image_attachment
      end
    end
  end
end
