this is my form+formset and the validation/error display works for both
at the same time.
maybe you can get yours working by comparing it
def myform(request):
idea_form = ProjectideaForm
activity_formset = inlineformset_factory(Projectidea, Activity,
extra=5)
if request.method == 'POST': # If the form has been submitted...
form = idea_form(request.POST)
formset = activity_formset(request.POST,
instance=Projectidea()) # A form bound to the POST data
if form.is_valid() and formset.is_valid(): # All validation
rules pass
new_idea = form.save()
formset_models = formset.save(commit=False)
for f in formset_models:
f.projectidea = new_idea
f.save()
return HttpResponseRedirect(new_idea.get_absolute_url())
# Redirect after POST
else:
form = idea_form()
formset = activity_formset()
return render_to_response('fslform/fslform.html',
{'form' : form, 'formset': formset,},
context_instance=RequestContext(request))
