I want to implement a simple 2 part FormWizard. Form 1 will by dynamically generated something like this:

class BuyAppleForm(forms.Form):
   creditcard = forms.ChoiceField(widget = forms.RadioSelect)
   type = forms.ChoiceField(widget = forms.RadioSelect)
   def __init__(self,*args, **kwargs):
        user = kwargs['user']
        del kwargs['user']

        super(BuyAppleForm, self).__init__(*args, **kwargs)

        credit_cards = get_credit_cards(user)
        self.fields['creditcard'].choices = [(card.id,str(card)) for card in credit_cards]

        apple_types= get_types_packages()
        self.fields['type'].choices = [(type.id,str(type)) for type in apple_types]

This will dynamically create a form with lists of available choices.

My second form, I actually want no input. I just want to display a confirmation screen containing the credit card info, apple info, and money amounts (total, tax, shipping). Once user clicks OK, I want the apple purchase to commence.

I was able to implement the single form way by passing in the request.user object in the kwargs. However, with the FormWizard, I cannot figure this out.

Am I approaching the problem wrong and is the FormWizard not the proper way to do this? If it is, how can the Form __init__ method access the user object from the HTTP request?
