cant pass initial values to a formset using curry - django

Question

as per this SO question Django Passing Custom Form Parameters to Formset im tryin to use curry to pass a dictionary of initial values to my formset.
its not working, it gives me a formset of empty values, which isn't what its supposed to do.
can anyone see if im implementing this wrong?
data = {'supplier': input_data['supplier'],}
InstanceFormSet = formset_factory(BulkAddInstanceForm, extra=int(input_data['copies']))
InstanceFormSet.form = staticmethod(curry(BulkAddInstanceForm, data))
EDIT: as requested
class BulkAddInstanceForm(forms.Form):
def __init__(self, *args, **kwargs):
super(BulkAddInstanceForm, self).__init__(*args, **kwargs)
self.fields['supplier'] = forms.ModelChoiceField(
queryset=Supplier.objects.all(),
label='Supplier',
empty_label='Select a Supplier...',
required=True,
)
self.fields['syllabus'] = forms.ModelChoiceField(
queryset=Syllabus.objects.all(),
label='Syllabus',
empty_label='Select a Syllabus...',
widget=FilterWidget(
queryset=Syllabus.objects.all(),
parent_queryset=Supplier.objects.all(),
control_name='supplier',
parent_attr='supplier',
),
required=False,
)
self.fields['venue'] = forms.ModelChoiceField(
queryset=Venue.objects.all(),
label='Venue',
empty_label='Select a Venue...',
widget=FilterWidget(
queryset=Venue.objects.all(),
parent_queryset=Supplier.objects.all(),
control_name='supplier',
parent_attr='supplier',
),
required=False,
)
start_date = NiceDateField(required=False, label='Start Date')
residential = forms.BooleanField(label='Res?', required=False)
special_offers = forms.BooleanField(label='S/O?', required=False)
manual_price = forms.IntegerField(required=False)
manual_cost = forms.IntegerField(required=False)

I have looked at the docco and it suggests to do a different thing.
formset = formset_factory(BulkAddInstanceForm, extra=int(input_data['copies']))
formset = InstanceFormSet(initial=[data, ])
which creates a formset with 'copies' amount of forms, plus another one with the data in.
if i do this
formset = InstanceFormSet(initial=[data, data])
then i get two extra forms with the data in.
so my idea is i need an iterator to add 'copies' number of dictionaries and zero the initial number of forms in the formset.
not that i know how to cod that yet!!

Answer 1

managed to do it with the following code:
InstanceFormSet = formset_factory(BulkAddInstanceForm, extra=0)
# build the list for populating the forms
n, datalist = 0, []
while n < int(input_data['copies']):
datalist.append(data)
print datalist
n +=1
formset = InstanceFormSet(initial=datalist)
so i create the formset, then i create a list of the data dictionaries, then populate the formset with the inital data as a list.
seems to be working so far, though i've got to work out how to collect and submit the info yet .

You would need to pick up the value you're passing in during the __init__
When I've used this in the past, I've set up the parameter as such:
class MyForm(forms.Form):
def __init__(self, data, *args, **kwargs):
self.data = data
#do whatever else I need to do with data
super(MyForm, self).__init__(*args, **kwargs)
Hope that helps you out.
