No, you have provided four keyword arguments. The signature for the
delete_object function is as follows:
def delete_object(request, model, post_delete_redirect,
object_id=None,
slug=None, slug_field='slug', template_name=None,
template_loader=loader, extra_context=None,
login_required=False,
context_processors=None, template_object_name='object'):
So you need to pass request, model and post_delete_redirect *without*
keywords, as simple positional arguments:
return delete_object(request, User, '/notify/delete_done/',
template_name='delete.html', login_required=True)
However more of a worry is the code before that call. I'm not sure
what you think it is doing, but it isn't doing it. If the user is a
superuser, it's iterating through all users in the database, getting
their user ID, then immediately discarding it. It will then pass the
ID of the *last* user to delete_object. I suspect that isn't what you
wanted.
