Rails 5.2 Active Storage 不删除附加的图像

Question

I'm trying to delete an image that's attached to a job post. But after clicking on remove, the attached image is still there and doesn't get deleted from the job post.

Job Show page

<div class="ui text container slides">
        <i class=" left angle icon"></i>
        <i class=" right angle icon"></i>
       <% @job.images.each_with_index do |image, index| %>
        <div class="slide active">
          <%= image_tag image, size: 200 %> 
 <%= link_to 'Remove', delete_image_attachment_job_url(image.signed_id),
                    method: :delete,
                    data: { confirm: 'Are you sure?' } %>
                </div> 
         <% end %>
    </div>
  </div>

routes

  resources :jobs do
  member do
    delete :delete_image_attachment
  end
end

jobs_controller.rb

def delete_image_attachment
    @image = ActiveStorage::Blob.find_signed(params[:id])
    @image.purge
    redirect_to root_path
end

Answer 1

In my controller, i replaced @image = ActiveStorage::Blob.find_signed(params[:id]) with:

def delete_image_attachment
    @image = ActiveStorage::Attachment.find(params[:id])
    @image.purge
    redirect_back(fallback_location: job_path) 
end

My delete action is now:

<%= link_to 'Remove', delete_image_attachment_job_url(image),
                method: :delete,
                data: { confirm: 'Are you sure?' } %>
