Question

I am trying to build a django form wizard to allow people to register for an
event. I can get through the form wizard and see data in the done method.
The problem is that I also need event_id passed into done also. How do I get
event_id from the url through the form wizard and into done? Simple example?

------- urls.py ---------
named_register_forms2 = (
    ('basicdata', SeatsForm),
    ('form2', AnotherForm),
)

urlpatterns = patterns('',
    url(r'^register/(?P<event_id>\d+)/$', register_wizard, name='register_step'),
)

------ forms.py -----------
class SeatsForm(forms.ModelForm):

  class Meta:
    model = MyModel
    fields = [ 'last_name', 'first_name', 'address1', 'address2', 
               'city', 'state', 'zipcode', 'phone_number', 'email']

  def __init__(self, *args, **kwargs):
      super(SeatsForm, self).__init__(*args, **kwargs)

class RegisterWizard(SessionWizardView):
    #storage_name = 'formtools.wizard.storage.session.SessionStorage'
    template_name = 'wizard_form.html'

    def done(self, form_list, **kwargs):
        data = {}
        for form in form_list:
                data.update(form.cleaned_data)
                print data
        # I need event_id right here.  How to get it?
        return render_to_response('done.html', {
            'form_data': [form.cleaned_data for form in form_list],
    })

I think you will have to put that in the form and get it from there.

If its model form you can pass instance_dict param to the wizard view. instance_dict param. However in that case you will have to implement a wrapper view that will prepare the wizard view with these params. Something like this:

def wrapper_view(request, id):
    #somecode
    seats_instance = SeatsModel.objects.get(id=id)
    another_instance = AnotherModel.objects.get(id=id)
    inst_dict = { '0': seats_instance,
                  '1': another_instance
                }
    return RegisterWizard.as_view(named_register_forms2, instance_dict=inst_dict)(request)

class RegisterWizard(SessionWizardView):
    #storage_name = 'formtools.wizard.storage.session.SessionStorage'
    template_name = 'wizard_form.html'

    def done(self, form_list, **kwargs):
        data = {}
        seatform= form_list[0]
        seatinst = form.save()    
        #save other forms
        ...
        #using seatinst get event id

        return render_to_response('done.html', {
            'form_data': [form.cleaned_data for form in form_list],
             })
