  <p>I'm here trying to inherit django-admin's <code>delete_confirmation.html</code> template. I want to add a <code>cancel</code> button at the time of deleting the objects in an app. It shows me cancel button and it also works fine but <code>delete</code> button does nothing by doing so.</p>
  
  <p>I've tried to add links in my "local template" which are defined in "admin template" but it raised error that "reverse url not found". Is there any workaround to do that? Please suggest me the right way to do it.</p>
  
  <p>Thanks in Advance. </p>
