Following is the dispatch function:
def dispatch(self, request, *args, **kwargs):
try:
user_check_id = self.request.session.get("user_checkout_id")
user_checkout = UserCheckout.objects.get(id=user_check_id)
except UserCheckout.DoesNotExist:
user_checkout = UserCheckout.objects.get(user=request.user)
except:
user_checkout = None
obj = self.get_object()
if obj.user == user_checkout and user_checkout is not None:
return super(OrderDetail, self).dispatch(request, *args,
**kwargs)
else:
raise Http404
On line 27 color is red. Usually the error related to SimpleLazyObject
means that it's not able to grab the field with reference. I don't know
what to replace it with.
