I am happy to help,
You should create one form per item and choose a smart prefix for each form
created, this example show only how to add multiple items.
But you can edit items too by using id as a prefix you will be able to get
an instance of the object for form creation.
something like that:
form_submit = False
if request.POST:
# POST data => we should try to validate
# always keep a list of ids of the item you edit
ids_string = request.POST.get('ids', None)
ids = ids_string.split(',')
form_submit = True
# we have post DATA we should validate/submit change
# MyModelForm is a ModelForm Class
all_forms = [MyModelForm(request.POST, prefix=str(id),
instance=model.objects.get(pk=id)) for id in ids]
if all( [ form.is_valid() for form in all_forms] ):
# All forms are valid we can update and save the object
for form in all_forms:
# update object field
form.save()
Message( id=None, user=request.user, message=_(u"success")
).save()
return ttpResponseRedirect(
"Where/you/want/after/a/valid/edit/")
else:
Message( id=None, user=request.user, message=_(u"fail") ).save()
if not form_submit:
# no POST data we should initiate the forms
# handle ids
ids_string = request.GET.get('ids', None)
ids = ids_string.split(',')
# Create the Custom ModelForm
all_forms = [ MyModelForm(prefix=str(id),
instance=model.objects.get(pk=id)) for id in ids ]
Hope this still helps
