Hi, I am trying to fill in *choices *for MultipleChoiceField in runtime. I am using formWizard and trying to return the dictionary using get_form_kwargs.
I am able set the *initial* for CharField but not *choices *for
MultipleChoiceField.
I am trying to show up dynamic choices based on the user's input in first
form. This choices will be calculated using form 1 cleaned_data.
views.py
--------
class SelectWizard(*SessionWizardView*):
def get_form_initial(self, step):
if step == 'select':
initial={'release_id': 'Major.Minor.Patch'}
return initial
return self.initial_dict.get(step, {})
def get_form_kwargs(self, step=None):
if step == 'select':
# Calculate the choices here from form 1 cleaned data
'''
cd = self.get_cleaned_data_for_step('main')
'''
return {'data': {'choices': (('1', 'Option1'),
('2','Option2'))},} # Manual for now
return {}
def done(self, form_list, **kwargs):
# do something
return HttpResponseRedirect('/queued/')
-----
forms.py
class Selection(forms.Form):
def __init__(self, *args, **kwargs):
* print 'kwargs', kwargs*
super(Selection, self).__init__(*args, **kwargs)
self.fields['release_id'] =
forms.CharField(initial=kwargs['initial']['release_id'])
self.fields['choose_items'] =
forms.MultipleChoiceField(choices=(('3', 'Option3'), ('4', 'Option4')))
# choices_tuple = kwargs['data']['choices']
# self.fields['choose_items'] =
forms.MultipleChoiceField(choices=choices_tuple)
release_id = forms.CharField()
choose_items = forms.MultipleChoiceField()
