Question

I have problem on accessing the form data from a formset. I attached the code:

####FORM
class ActionTypeForm(forms.Form):
     action_name = models.CharField(max_length=20)
     description = models.CharField(max_length=250, blank=True, null=True)


####VIEW
dataset = request.POST
ActionTypeFormSet = formset_factory(ActionTypeForm)
formset = ActionTypeFormSet(dataset)

if formset.is_valid():
     for form in formset.cleaned_data:  #I ALSO TESETED formset.forms
           customer.create_actiontype(form['action_name'], form['description'])

the error is I can’t get form[‘action_name’]. formset.is_valid() return True

ERROR

Exception Type: KeyError

Exception Value: ‘action_name’

POST DATA

form-0-action_name u’a’

form-2-description u’sadsa’

form-0-description u’a’

form-MAX_NUM_FORMS u”

form-1-description u’asd’

form-TOTAL_FORMS u’3′

form-1-action_name u’as’

form-INITIAL_FORMS u’0′

Answer 1

The main problem is that you have a blank form. You are using model fields in your form class definition, which django’s forms framework has no idea what to do with. Django models != django forms.

The formset is validating and returning empty forms which of course have no form fields.

You should either create Formsets out of forms with valid form fields, or ModelFormsets out of Models.

• Update: I initially thought that formsets don’t have cleaned_data, but I guess they do return a list of cleaned_datas of all forms, which means the problem with your code is just the above.
