python - Django Form Wizard persistent initial data between steps -

i'm using django form wizard in project. want allow users provide initial data specific field , want make field initial data provided disabled.

problem when user clicks button initial data erased.

for example form(initial data set second step) can see fine here, form fields disabled , value selected. click next.

click next , second step without problems if click back..

form fields still disabled value gone!

the code i'm using goes (relevant part):
form

choices=[('one','choice 1'),          ('two','choice 2'),          ('three','choice 3'),          ('four','choice 4'),         ]  class bookingform1(forms.form):     """ select reservation type"""     sko = forms.choicefield(choices=choices, widget=forms.radioselect()) 

wizard

def get_form(self, step=none, data=none, files=none):         form = super(presentview, self).get_form(step, data, files)         step = step or self.steps.current          initial = {             'sko': {                 'initial':'two'             }         }          field in initial:             try:                 form.fields[field].widget.attrs['readonly'] = true                 form.fields[field].widget.attrs['disabled'] = true                 form.fields[field].required = false                 form.fields[field].initial = initial[field]['initial']             except:                 pass 

any ideas appreciated!

the way able solve removing fields choicefield type objects.

 field in initial:             try:                 field_o = form.fields[field]                 # remove choices if choice field                 if type(field_o) == forms.fields.choicefield:                     field_o.choices = [(key, value) key,value in field_o.choices if key == initial[field]['initial']]                 else:                     field_o.widget.attrs['readonly'] = true                  field_o.initial = initial[field]['initial']             except:                 pass
