Hi!
I've been stuck with this for some days now, and can't find any
answers whatsoever. Please bare with me since I'm a newbie with Python/
Django.
I have this form that's created and populated using
'modelformset_factory'. What it's supposed to do is to
1. show a number of sets so the user can add several at one time. Also
show the added ones, with the possibility to delete them if necessary.
2. Save content. This means insert/update/delete.
Easy enough, ey? But I'm stuck at the error "AttributeError:
'OptionForm' object has no attribute 'cleaned_data'". Strange things
happen here. "OptionForm" doesn't exist for example. I guess Django
adds "Form" by itself, why I don't know.
The full traceback:

formset = OptionFormSet(request.POST, request.FILES,
queryset=instance)
formset.save()
return HttpResponseRedirect(reverse(OptionEdit, args=
[invite_id, form_id, field_id]))
else:
OptionFormSet = modelformset_factory(Option, extra=2,
can_delete=True)
formset = OptionFormSet(queryset=instance)
return render_to_response('invites/options_edit.html', {
'formset': formset,
'invite_id': invite_id,
'form_id': form_id,
})
options_edit.html:
-----------------
<form name="frm1" method="post" action="">
<table>
{{ formset }}
<tr>
<td colspan="2"><hr /></td>
</tr>
</table>
<input type="submit" />
</form>
So, I'm really appreciate if you could help out an old VB coder with
this mess. Otherwive it seems like a super framework, if you only
could decode those error messages that's not very clear all the time.
Thanks!
