Thanks for the clarification.
Apparently my demo case of the problem was not appropriate, but my
real problem is still there.
I have 2 ModelForms that I want to receive data at a single form
submission.
item_form is required only if 'item' field of the entry_form is
empty.
So I build the logic in my view that handles the form as follows:
def form(request):
...
if request.method == 'POST':
item_form = ItemForm(request.POST, instance=item)
entry_form = EntryForm(request.POST, instance=entry)
if entry_form.is_valid():
e = entry_form.save(commit=False)
e.user = request.user
if not form.cleaned_data['item']:
if item_form.is_valid():
e.item = item_form.save()
else:
return render_to_response(...)
e.save()
return HttpResponseRedirect(...)
else:
return render_to_response('blog/form.html',
{'entry_form': entry_form,
'item_form': item_form,
context_instance=RequestContext(request))
But when I submit an invalid entry_form (i.e. nothing related to item
form is executed or accessed other then the initialization item_form =
ItemForm(request.POST, instance=item)) the item_form arrives at my
template with a filled errors dictionary.
Any opinions?
