Problem

I have a DeleteView. In which i want to access related object id. When user make POST request. View: ``` 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) ``` But I am getting error when I try to submit form. Traceback: ``` Environment: Request Method: POST Request URL: http://localhost:8000/delete/packet/96/ Django Version: 1.7 Python Version: 2.7.8 Installed Applications: ('django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'myapp') Installed Middleware: ('django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.contrib.admindocs.middleware.XViewMiddleware') Traceback: File "C:\Users\PrImE\envs\ge\lib\site-packages\django\core\handlers\base.py" in get_response 111. response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\PrImE\envs\ge\lib\site-packages\django\views\generic\base.py" in view 69. return self.dispatch(request, *args, **kwargs) File "C:\Users\PrImE\envs\ge\lib\site-packages\django\utils\decorators.py" in _wrapper 29. return bound_func(*args, **kwargs) File "C:\Users\PrImE\envs\ge\lib\site-packages\django\contrib\auth\decorators.py" in _wrapped_view 22. return view_func(request, *args, **kwargs) File "C:\Users\PrImE\envs\ge\lib\site-packages\django\utils\decorators.py" in bound_func 23. return super(LoginRequiredMixin, self).dispatch(*args, **kwargs) File "C:\Users\PrImE\envs\ge\lib\site-packages\django\views\generic\base.py" in dispatch 87. return handler(request, *args, **kwargs) File "C:\Users\PrImE\workspace\myproject\repo\dev\myproject\myproject\myapp\views\delete_views\delete_packet_view.py" in post 66. kwargs={'pk': self.object.customer.id Exception Type: AttributeError at /delete/packet/96/ Exception Value: 'DeletePacketView' object has no attribute 'object' ``` I am getting this error because the object is deleted. But `get_success_url` method works fine it is redirecting user to the customer page why not post method is working and how do I access `self.object.customer.id`???
