Accessing variables in Django forms

Question

The problem I've run into here is how to display some additional text in a form, specifically the values of the previous step. The point is to show the user a message such as "you have chosen {{ value_from_step_0 }} as your starter, now choose a main course."

I can get that value from step 0 as follows:

class MenuWizard(SessionWizardView):
    def get_form_kwargs(self, step=None):
        kwargs = {}
        if step == '1':
            starter = self.get_cleaned_data_for_step('0')['starter']
            kwargs.update({'starter': starter})

class MainCourseForm(forms.Form):
    def __init__(self, *args, **kwargs):
        starter = kwargs.pop('starter')
        print "{0} chosen".format(starter) # This works
        super(DomainForm, self).__init__(*args, **kwargs)
        # What next?

If I don't pop the 'starter' value then the super call fails. But, how may I get that value into the relevant template? Presumably I need to do something further within init or override something else, but what?

First, note that 1.7 is unsupported, and the form wizards were removed from Django in 1.8 and are now in the third-party formtools library.

This isn't really a job for the form, but the view. SessionWizardView is a standard class-based view, and like most class-based views it allows you to override get_context_data to add elements to the template contents. See the documentation, which has an example of using self.steps.current to check the current step name.
