Delete() an instance

Question

In my view:

def delete_payment(request, id):
    thePayment = Payment.objects.filter(id=id)
    thePayment.delete()
    return HttpResponseRedirect('/invoices/open/')

In my model:

def delete(self, *args, **kwargs):
    raise Exception('foo')
    super(Payment, self).delete(*args, **kwargs)

I'm finding that the exception doesn't get raised unless I delete the instance from within the admin view. That is, I can't get delete() to be called properly if I use my own view.

Answer 1

Manager.filter() returns a QuerySet, not a Model. QuerySet.delete() doesn't invoke Model.delete() but rather operates directly on the database.
