보기 :

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 
             } 
          )

개체가 삭제 되었기 때문에 나는이 오류를 얻고있다. 그러나 get_success_url 메서드가 제대로 작동하여 사용자를 고객 페이지로 리디렉션하는 이유는 무엇입니까 게시 메서드가 작동하고 어떻게 액세스합니까 self.object.customer.id ???
