Hi Peter and others,
your idea was good, but it does not work with Django ORM Models:
Traceback (most recent call last):
File "/localhome/modw/django/core/handlers/base.py", line 87, in get_response
response = callback(request, *callback_args, **callback_kwargs)
File "/localhome/modw/foo/views/filter.py", line 473, in add
return edit(request, 'add')
File "/localhome/modw/foo/views/filter.py", line 493, in edit
filter=form.save()
File "/localhome/modw/foo/views/filter.py", line 457, in save
action=form.save()
File "/localhome/modw/django/forms/models.py", line 315, in save
if self.instance.pk is None:
File "/localhome/modw/django/db/models/base.py", line 292, in _get_pk_val
return getattr(self, meta.pk.attname)
AttributeError: 'MyAction' object has no attribute 'filter_action_ptr_id'
