如何访问DeleteView中的相关对象ID

我有一个DeleteView。我想在其中访问相关的对象ID。当用户发出POST请求时。如何访问DeleteView中的相关对象ID

查看：

class DeletePacketView(LoginRequiredMixin, DeleteView): 

    model = Packet 
    template_name = DELETE_PACKET_TEMPLATE 

    def get_success_url(self): 

     # Return to customer home 
     return reverse('myapp:view_customer', 
         kwargs={'pk': self.object.customer.id 
           } 
         ) 

    def post(self, request, *args, **kwargs): 

     html = """ 
       <html> 
        <head> 
         <script>window.onunload = refreshParent; function refreshParent() { 
           window.opener.location.href=%s; 
           } 
         </script> 
        </head> 
        <body> 
        <h1>object deleted successfully</h1> 
        <button type="button" onclick="window.close()">OK</button> 
        </body> 
       </html> 
       """ % reverse('myapp:view_customer', 
           kwargs={'pk': self.object.customer.id 
             } 
          ) 
     super(DeletePacketView, self).post(request, *args, **kwargs) 
     return HttpResponse(html)

但我得到的错误，当我尝试提交表单。

，因为被删除的对象，我得到这个错误。但get_success_url方法工作正常它将用户重定向到客户页面为什么不能发布方法正在工作以及如何访问self.object.customer.id ???

def post(self, request, *args, **kwargs): 
    self.object = self.get_object() #Add this to load the object 
    #Your code 
    return HttpResponse(html)

PS：请使用Django模板;）
