In cases like this, rather than rely on overriding the default behavior of
the DeleteView,
I'd recommend writing your own base class.
It'll be more explicit and more obvious exactly what is going on...
from django.views.generic import View
class MarkDeletedView(View):
"""
Base class for marking a model instance as deleted.
"""
model = None
redirect_url = None
def delete(self, request, *args, **kwargs):
assert self.model, "model attribute must be set"
assert self. redirect_url, "redirect_url attribute must be set"
object = get_object_or_404(self.model, pk=kwargs['pk'])
if object.date_deleted is not None:
raise Http404
now = datetime.datetime.utcnow().replace(tzinfo=utc)
object.date_deleted = now.strftime("%Y-%m-%d %H:%M:%S")
object.save()
return HttpResponseRedirect(self.redirect_url)
Then you can create a different view for each model you need this behavior
on, like so...
class CustomerDeleteView(MarkDeletedView):
model = Customer
redirect_view = reverse('customer-list')
Hope that helps.
