Thanks, the missing prefix was indeed one issue, although prepopulating with data is not a problem. It didn't solve the problem though. The problem arises from the fact that I'm rendering multiple forms, but the user is POSTing back only one form. Each form has it's own submit field. How do I know which form was submitted?

You are absolutely right, I added that. Thanks. 2B --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

You forgot to set the prefix here, so the form that the user is
submitting their data from doesn't have the fields named correctly. You
need to set it up exactly the same way at this point as you did in the
POST path, with the exception of not prepopulating with data.
Also, you've almost certainly left off an "else" clause here. You only
want to create new, empty forms if the method is not POST (you can fall
through to this point with request.method == "POST" and one of the forms
being invalid).

Malcolm

Multiple instances of the same form on one page: how to get the right POST data?
I'm trying to add multiple instances of the same form on one page,
each with its own submit button. I know how to use the 'prefix'
argument for a form to differentiate between forms, but I can't figure
out how to get the right data when it is POST'ed back (see view.py
below). Somehow the form stays invalid, no matter what I try. Any
suggestions what I may be doing wrong?
Thanks!

invitation= models.ForeignKey(Invitation, verbose_name=_
('User'))
email_address = models.EmailField(_('email address'))
status= models.CharField(_('RSVP status'), max_length=1,
choices=settings.INVITE_RESPONSE_CHOICES)
=views.py===
def invite_resp(request):
invites = Invite.objects.all()
if request.method == 'POST':
invite_formz = [InviteForm(request.POST, prefix=str(index),
instance=invite) for index, invite in enumerate(invites)]
if all([invite_form.is_valid() for invite_form in
invite_formz]):
invite = invite_form.save()
return HttpResponseRedirect('/')
invite_forms = [InviteForm(instance=invite) for index, invite in
enumerate(invites)]
return render_to_response('invite_resp.html', {'invite_forms':
invite_forms}, context_instance=RequestContext(request))
=forms.py
class InviteForm(forms.ModelForm):
def __init__(self, label, *args, **kwargs):
super(InviteForm, self).__init__(*args, **kwargs)
self.fields['status'].label = label
class Meta:
model = Invite
exclude = ('invitation', 'email_address')
=page.html===
{% block content %}
{% for invite_form in invite_forms %}
